Log of Changes and Improvements to Sierra Chart

This list contains major items of development, items which are notable, and changes and additions which users need to be informed about.

This is not a comprehensive changes and additions log. It only represents probably 25% of the actual development. There are not version notes for each version. The main Sierra Chart documentation is updated as needed relating to the changes and additions.

In addition to the below listed items for each version, there are also various low-level improvements, issues resolved, and small additions that a release may have which are not listed.

  • 1070 Release Date: 2014-01-03

    • Added support for the Eurex and ICE markets when using the Sierra Real-time and Historical Futures data feed.
    • Enhancements and issues resolved with the new Continuous Futures Contract functionality with back adjustments.
  • 1068 Release Date: 2013-12-31

    • Corrected some issues with the new Continuous Futures Contract feature when using the volume-based rollover method.
    • Corrected issue where when using the TT FIX trading platform service, the CME exchange code was not being translated to CBOT to match the symbols of charts for Orders and Positions, when using the CME gateway. This only caused a problem when the symbol used CBOT for the exchange. This problem would result in a Trade Position quantity momentarily displaying on a chart after a position has been initiated in a CBOT market, and then it would go back to 0. This is now resolved.
    • It is now possible for an ACSIL function to modify these SC members: sc.StartTime1, sc.EndTime1, sc.StartTime2, sc.EndTime2, sc.UseSecondStartEndTimes.
  • 1066 Release Date: 2013-12-28

    • Completely new Continuous Futures Contract functionality with back adjustments has been developed in this version. After updating to this version, you will need to manually enable the Continuous Futures Contract feature on the particular charts that you want. This is set through Chart >> Chart Settings >> Advanced Settings >> Continuous Contract. The choices are as follows:
      • None
      • Continuous Futures Contract - Date Rule Rollover
      • Continuous Futures Contract - Volume Based Rollover
      • Continuous Futures Contract - Date Rule Rollover, Back Adjusted
      • Continuous Futures Contract - Volume Based Rollover, Back Adjusted

      This new functionality is a major step forward with the Continuous Futures Contract functionality that Sierra Chart has previously offered. If you are using Continuous Futures Contracts from IQ Feed, then we highly recommend looking at what we offer. Please also be aware that we offer our own Sierra Chart Real-Time and Historical Exchange Data Feed now.
    • This version supports the new Sierra Chart server protocols for real-time data. All users will need to update to this version or higher by January 31, 2014 to continue to receive real-time data from the Sierra Chart servers. This includes market statistics and Forex data.
  • 1063 Release Date: 2013-12-17

    • Various small improvements related to the Sierra Chart Real-Time and Historical Data Feed. If you are using the Sierra Chart Real-time and Historical Futures Data Feed, it is essential to update to this version as soon as possible.
    • Corrected a problem where when replaying multiple charts, Skip Empty Periods was enabled, and the auto trade system back test option was not set, the charts would lose synchronization with each other after two minutes of replay. The Skip Empty Periods option on the replay window is now properly implemented.
    • Added a new Volume Graph Period Type to the Volume by Price study, named Multiple Profiles from Start Time to End Time. This can be used to create multiple volume profiles in the chart that cover a shorter duration of time in the chart than specified by the Session Times you have set in Chart Settings. Use the Start Time and End Time inputs with the Volume by Price study to set the start and end time respectively.
    • New Cycle tool features to allow the cycle node and mid-points to have vertical lines drawn. These are off by default, but can be turned on per drawing and in the drawing configurations for future drawings. There is also an option that will allow the vertical lines to be drawn only when the drawing is being modified.
  • 1061 Release Date: 2013-12-08

    • With the TT FIX and the AMP/TTNet trading services, there is now better organization and handling of CBOT symbols that should be routed through the CME gateway. There is a new setting named: Global Settings >> Data/Trade Service Settings >> Use CME Gateway for CBOT Symbols . Normally this should be enabled, unless CBOT symbols should not use the CME Gateway. Your broker will inform you how this should be set. It is recommended to keep it enabled unless orders get rejected or you do not receive market data for a CBOT futures market symbol. When updating to this version, it is recommended to perform a Full Reset of symbol settings if using the TT FIX and the AMP/TTNet trading services.
    • Corrected a problem from a recent release with the internal setting of the Maximum Historical Intraday Days to Download when historical Intraday is downloaded using the Sierra Chart server protocols. This was being set to a maximum of 100 when it should be a minimum of 100. The 100 days minimum does not apply when Intraday data is downloaded from an external service like Interactive Brokers.
    • When the Sierra Chart Futures Data feed, and you modify the Global Symbol Settings for a symbol, the settings necessary for the mapping of the trading service symbol to the Sierra Chart symbol, may have been lost. This problem is now resolved.
    • New ACSIL variables added: sc.BaseGraphScaleRangeTop, sc.BaseGraphScaleRangeBottom, sc.BaseGraphScaleValueOffset, sc.BaseGraphAutoScalePaddingPercentage.
  • 1057 Release Date: 2013-12-1

    • With the new Sierra Chart Real-time Futures data feed which is integrated with all of the supported Trading services, when you become disconnected from the server for one of the supported Trading services and Sierra Chart is in a reconnecting state, the Sierra Chart real-time futures data feed will continue to be received. So for example, with Interactive Brokers, you will continue to receive the data feed even if Trader Workstation shuts down.
  • 1055 Release Date: 2013-11-30

    • Performance improvements with historical data downloading and real-time chart updating. These improvements will be especially noticeable with historical tick data downloading.
    • Corrected a problem for recent release where there could be an abnormal shutdown of Sierra Chart while downloading historical data . This would only occur under certain conditions.
    • The TPO Profile Chart and Volume by Price studies now both fully support Peak and Valley lines with labels. Peak and Valley lines have the following extend options: None, Extend to End of Period, Extend to End of Window, and Extend To Intersection.
  • 1052 Release Date: 2013-11-25

    • Improvements to the Bitcoin Data services. There are now 50 levels of market depth available. There is a new service named Bitcoin Data (All Services) which combines all of the data feeds from the various Bitcoin exchanges into a single service. The symbols can be found through File >> Find Symbol.
    • Corrected a problem with the CTS FIX connection where because CTS no longer sends the Contract tag through the FIX messages, this would cause market data to be ignored and numerous messages added to the Message Log indicating the symbol could not be found. The problem is now resolved.
  • 1049 Release Date: 2013-11-20

    • Performance improvements with the downloading of historical Intraday data.
    • Corrected a problem where when there is continuously changing Daily High and Low data from a data service, Historical Daily charts will reload when the new High and Low values indicate a new trading day has begun. There has been problems with the Daily High and Low data from the FXCM Forex data feed, recently.
    • Numbers Bars enhancements: When Text Coloring value of Text On Dominant Side or Text On Dominant Side Auction is used, the compare values are now used instead of just looking at which value is greater. So, if the compare values are set to "150, 200, 300", the Bid/Ask volume are compared, and if the bid volume was greater than 300% of the ask volume, the Down Quartile 4 Color is used, else if greater than 200% of ask volume, the Down Quartile 3 Color is used, else if greater than 150% of ask volume, the Down Quartile 2 Color is used, else the Down Quartile 1 Color is used. The same goes for the ask volume, but the Up Colors are used instead of the Down Colors.

      If compare inputs are specified as values < 1.0 (i.e. .25), they are interpreted as 100 * value + 100 (i.e. .25 -> 125%).
  • 1047 Release Date: 2013-11-18

    • Corrected some issues with the Zig-Zag study where the data outputted to the Spreadsheet columns was not correct. Data was outputted to some rows when it should not have been and the rows for the Zig-Zag line end points, did not always have data. Also, corrected a problem where the labels may not have always appeared at the end points (this was a less common condition).
    • Increased the number of market depth levels to 50. Any ACSIL study which uses the sc.SymbolData member must be recompiled when using this version or higher. Otherwise, the study may be unstable.
    • The Time and Sales data structure, s_TimeAndSales has changed. There is now a single DateTime member of a SCDateTime type for the Date-Time and not individual members for the Date, Hour, Minute, Second. An ACSIL study that uses the Time and Sales data must be recompiled and be updated to use the new s_TimeAndSales::DateTime member, for it to be used on this version or higher.
    • The implementation of millisecond time stamping is now complete. The next step is to use this functionality in areas of Sierra Chart that will benefit from it. This is partially complete and will be ongoing. Sierra Chart uses millisecond time stamping as a counter to identify multiple trades within the same second. One major exchange like the CME, does not provide millisecond timestamps on trades. Therefore, it cannot be known exactly when a trade occurred within a second. Sierra Chart does not support estimating milliseconds in these cases. As is previously said, Sierra Chart uses milliseconds as a counter.
    • In the Time and Sales window, you will notice that each trade now contains a millisecond component in the Time column.
    • For the new Sierra Chart Real-time and Historical Futures Data Service, there is now 100% consistent identification of whether a trade occurred at the Bid or Ask.
    • When the Intraday Data Storage Time Unit is set to 1 Second or 1 Tick, and Historical Intraday data is downloaded in Ticks or Seconds, which will be the case for many supported Data/Trading services if the Intraday Data Storage Time Unit is set to 1 Second or 1 Tick, unless there is a separate setting for this for the particular Data/Trading Service you are using, then when a historical data download is completed, any missing trades that were not received between the last downloaded trade and the most recent trade, are added into the Intraday chart data file from the Time and Sales data. The implementation of this is all rather complex and has a reliance upon millisecond time stamping when it is used to count trades within the same second. Which is another reason, why Sierra Chart does not support milliseconds from external data feeds which do not necessarily accurately represent when a trade occurred, but only represent sending/receiving time of a message containing a trade.
  • 1046 Release Date: 2013-11-13

    • Continuing development to fully support millisecond timestamps. And improvements with historical data downloading
    • Corrected a problem from a recent release where when using the Rithmic/Zen-Fire trading services, the available trade accounts were not being listed on the Trade Window. This is now resolved.
  • 1044 Release Date: 2013-11-09

    • Corrected a problem arising in a recent release that prevented the MTGox trading service from being used. All order submissions will have mistakenly given an error indicating that the API Key and Secret were not set up when they were.
    • Improvements to the interface to the Sierra Chart Real-Time Futures Data Feed.
    • Correction of the current quote data used from a remote instance when there are multiplier differences between the Source and Destination Data/Trading services. This may not work under all conditions. However, it does work properly when using IQ Feed as a source data service and destination trading services like CTS T4 and TT FIX.
  • 1042 Release Date: 2013-10-30

    • For the TPO Profile Chart study, the midpoint calculation has now been changed to be the midpoint of the price range of the profile, rather than the midpoint of the TPO block/letter count per price level.
    • The Numbers Bars Calculated Values has the following new subgraphs: High Pullback Ask/Bid Vol Diff, Low Pullback Ask/Bid Vol Diff.
    • This version has complete support for the new Sierra Chart Real-Time and Historical Exchange Data Feed.
  • 1040 Release Date: 2013-10-30

    • Corrected a problem where order fills always had and Open/Close status of Open when performing a bar based back test. This is resolved.
    • When using the custom studies DLL compiler (Analysis >> Build Custom Studies DLL), it is now possible to select multiple files to compile and compile them all at once. Only one file can contain the SCDLLName line. All of the files are compiled into a single DLL file.
    • Low-level development to support the new upcoming CME real-time data feed.
  • 1039 Release Date: 2013-10-26

    • Added a new Volume Graph Period Type to the Volume by Price Study named: From Start Time to End Time.
    • When a DTC::s_SecurityDefinitionResponse message is received, this will add the symbol and its associated settings to Global Settings >> Symbol Settings and therefore it will be listed in File >> Find Symbol. We have noticed that in older versions of Sierra Chart when you send a DTC::s_SecurityDefinitionResponse message, this possibly could cause an exception in Sierra Chart or a corruption of the message added to the Message Log. This is now resolved.
    • Added support to specify additional compiler parameters to the compiler when building a custom studies DLL. There is an edit box on the Build Custom Studies window for this.
    • Volume/Size Filter input settings have been added to the Time and Sales Bid Size and Time and Sales Ask Size studies.
    • CTS server-side OCO has now been restored and supports Stop and Limit orders as both Attached Orders and as top level orders without any children.
    • The Trade Statistics tab on the Trade Activity Log has been updated to use the Sierra Chart built-in and developed colored list component and not the Windows component. This makes it flicker free, very reliable, and fast.
    • Low-level development to support the new upcoming CME real-time data feed.
  • 1038 Release Date: 2013-10-24

    • Corrected an uncommon updating issue with the zigzag study and improved the efficiency of it.
    • Corrected a problem with the handling of order quantities for bitcoin trading. This would be an issue with quantities of 10 bitcoins or greater.
    • Resolved a rounding problem with profit/loss values in the Trade Activity Log.
    • Low-level development to support the new upcoming CME real-time data feed.
    • When using the Trading Technologies FIX trading platform service, if market depth data is not required for a symbol, market depth data updates will not be started or they will be unsubscribed from.
  • 1035 Release Date: 2013-10-15

    • Improvements with the handling of out of sequence messages on FIX connections. This is now handled more gracefully.
    • Various low-level improvements with trade simulation. It is now possible to do simulated trading when using data from a remote instance even if not connected to the data feed in the copy of Sierra Chart you are trading from.
    • Trailing stop orders are now controlled using the Time and Sales data from the chart that the orders originated from. This means that if a chart uses data from remote copy/instance of Sierra Chart, then that Time and Sales data will originate from the remote copy if Global Settings >> General Settings >> Use Non-Chart Data from Remote Instances is enabled. Therefore, if this option is enabled the trailing stop orders will be controlled by the chart data from the remote instance rather than by the data feed from the primary connected Trading service in the copy of Sierra Chart that the orders originated from.
    • Continued improvements with the new non-CLR version Spreadsheets and issues resolved with those Spreadsheets.
    • Corrected some issues with the Continuous Futures Contract feature for charts. There were some issues when a chart is opened or reloaded when not connected to the data feed.
    • Low-level development to support the new upcoming CME real-time data feed.
  • 1031 Release Date: 2013-10-05

    • Added keyboard shortcuts and ToolBar buttons for Interactive Scale Range and Interactive Scale Move.
    • when extending the Value Area or Point of Control for Volume or TPO profiles until future intersection, and there is no profile after the last profile displayed on the chart, then the lines will still be cut at the point where they intersect future prices.
    • Low-level development to support the new upcoming CME real-time data feed.
  • 1029 Release Date: 2013-09-28

    • Improvements with restoring the previous selected trade account when going out of Trade Simulation Mode.
  • 1028 Release Date: 2013-09-25

    • On Global Settings >> Graphics Settings >> Other tab, the option "Bold DOM Last Price" has been added. When enabled, the last price will be bolded in the ChartDOM and TradeDOM.
    • In the Global Settings >> Graphics Settings settings window, the ChartDOM Best Bid/Ask Box Background and TradeDOM Best Bid/Ask Box Background color settings have been added. These color settings allow a box to be highlighted between the best bid and best ask prices within the price column. Note, in addition to setting the color, these options need to be enabled (using Enable check box).
    • In the Global Settings >> Graphics Settings settings window, ChartDOM LastPrice At Bid Text, ChartDOM LastPrice At Ask Text, TradeDOM LastPrice At Bid Text and TradeDOM LastPrice At Ask Text color settings have been added. These allow the text color of the LastPrice to be set based on if it traded at the bid or ask. If the bid/ask can not be determined, then the normal price color is used. Note, in addition to setting the color, these options need to be enabled (using Enable check box).
    • Improved the connection logic to the TransAct trading service.
    • Improved the setting of Attached Order offsets inputs on the Spreadsheet for the Spreadsheet System for Trading study
    • These offsets are only set when an order will actually be submitted.
    • When Order Types are changed on a Spreadsheet System for Trading Spreadsheet, they immediately go into effect. Previously a full recalculation was necessary for the Order Types to be read.
    • Revision 2: For the TT FIX trading platform service, the separate ICE Account setting in Global Settings >> Data/Trade Service Settings has been removed. This is no longer compatible with the multiple account support that Sierra Chart has now. This setting was used for one particular clearing firm. The Account number that was entered in the previous ICE Account box, needs to be entered into the Accounts box after the main account number separated by a comma. For example: Account1, Account2. So if the ICE account is 25000, then enter 25000 after the existing Account in the Accounts box. On the Trade DOM or chart, you need to set the account you wish to trade on the Trade Window. So if a different account is required for ICE, then select that account number. Refer to the documentation here: http://www.sierrachart.com/index.php?page=doc/TradeWindow.html#SelectingTradeAccount
  • 1026 Release Date: 2013-09-18

    • Added new Data service named Bitcoin Data (BTC China). This service accesses the Bitcoin China data direct from Sierra Chart servers for reliability and complete historical data.
    • When switching from Trade Simulation Mode to non-simulated mode, and there are multiple trade accounts or you are not connected to your Trading service, the previous non-simulated trading account will be selected.
    • Added new Value of Subgraph study Subgraph Draw Style.
  • 1025 Release Date: 2013-09-14

    • Corrected a problem from version 1024 with multistage Intraday data downloads where Historical Minute data and historical Tick data are downloaded for a symbol. This would affect services like IQ Feed and CTS. If the Intraday data file was empty, then none of the downloaded data would be written to the output file. This is now resolved.
    • In ACSIL renamed DRAWSTYLE_DONOTDRAW to DRAWSTYLE_HIDDEN.
  • 1023 Release Date: 2013-09-12

    • Added new option to Graphics Settings window: Underline Chart Header Field Names. When this is enabled, the field names along the chart header line will be underlined to make it easier to locate a particular field and read the data for it.
    • With the TPO Profile Chart and TPO Value Area Lines studies, there is now a new input to control the starting time of 30 minute subperiods when a session Start Time is used which is not aligned to 30 minute times. This input is named 30 Minute Letter/Block Sub Period Handling. The options are Standard, Merge Odd Subperiod with Next, Start New Subperiods at Even 30 Minute Time Blocks.
    • Corrected a problem from a recent release where the Average Fill Price for orders when using the CTS T4 trading platform service, was not being set correctly.
  • 1019 Release Date: 2013-09-01

    • In the circumstance where you may need to go back to a prior version of Sierra Chart for whatever reason, beginning with version 1017, it is now guaranteed to always be able to open a Chartbook from a newer version of Sierra Chart even if new internal data fields have been added to Chartbooks in newer versions. This change is as of version 1017. You will no longer need to access a backup Chartbook which may not have all of your latest changes/additions. Any Chartbooks saved with a version after this version, will be able to be used in any prior version going back to version 1017.
    • With the new CTS FIX connection, Trade Positions are now determined through a FIX report which provides the current position for a market through simple calculations. Previously this was not possible. By using this new FIX report, there is more reliable Trade Position processing. Other enhancements and resolution of issues relating to the CTS FIX trading and market data interface.
    • Corrected a problem from a recent release where you may encounter compiler errors when building a Custom Studies DLL file.
    • Only orders that have been submitted from a particular trade account will be displayed on a chart or Trade DOM based upon the selected trade account on the associated Trade Window.
    • Continued development of the new spreadsheet functionality in the non-CLR version. It is now possible to refer to Study Subgraphs outputted to the spreadsheet by an alternate reference name. For more information, refer to this Support Board Thread. This prevents problems of cell formulas becoming invalid when studies are added or removed from the chart, or new Study Subgraphs are added to a study.
  • 1014 Release Date: 2013-08-22

    • Corrected some minor small issues relating to the updated protocol for interfacing to Interactive Brokers TWS. One issue resolved is the Account Balance should continuously update.
    • Corrected a problem with the Rithmic/Zen-Fire trading platform service from a recent release where the timestamps for Eurex trades were not correct.
    • Ongoing Spreadsheet development. The latest development can be seen in the non-CLR version. The Spreadsheet studies are now available to be used with a non-CLR version. There are still various small user interface items of development which need to be done for the Spreadsheets and this is still in progress.
    • Corrected a problem from a recent release where if the connection to the Market Statistics data feed is lost, it would not automatically reconnect. This is now resolved.
    • Order handling and trading integration improvements with the CTS FIX trading platform service.
  • 1010 Release Date: 2013-08-14

    • With the CTS FIX trading platform service, resolved a problem with order IDs when an order is canceled, which would prevent the order status from properly updating for the canceled order.
    • Added new Range per Bar type.
    • Small improvements to the interface to Interactive Brokers relating to Financial Advisor accounts and historical order fills.
  • 1007 Release Date: 2013-08-09

    • With the Volume by Price study, the Draw Peaks & Valleys input now contains options to draw Peaks only, Valleys only or both.
    • The chart Session Start Time and End Time are now outputted to cells J75 and J76 for all of the Spreadsheet studies.
    • Attached Orders can now be specified directly from the Spreadsheet System for Trading study Spreadsheet cells. The Target is set through J80 and the Stop is set through J81. When either of these are set (are nonzero), these will replace any existing Attached Orders for the chart and replace them with a simple Target and/or Stop using the offsets specified. The offsets need to be specified as an actual price value.
    • New studies added: Volume Zone Oscillator and Pivot Range-Variable Period.
    • New Chart/Trade DOM columns have been added: Recent Bid Volume and Recent Ask Volume. These Are Added through Global Settings >> Configure Chart/Trade DOM Columns These new columns will show the Bid Volume and Ask Volume for each price level where the market traded at before moving to a new price. When the market goes back to a prior price level, the Bid Volume and Ask Volume are reset.
    • Various improvements and issues resolved with the integration to CTS FIX trading platform service.
    • Support for the TransAct trading service is now restored. This was not supported in version 1004. Sierra Chart now provides order prices as integers to the TransAct bridge program to avoid any slight price inaccuracies due to floating-point error.
    • New trading study added: Trading: Position . This will display the trading position for the symbol of the chart as a historical graph.
    • Update to the logic of automated trading management where when there is a Buy or Sell Exit and Cancel All Working Orders on Exit is set to TRUE/Yes, market orders will not be considered as being cancelable, since they are unlikely to be canceled, and they will therefore be used in the calculation of the exit quantity and they will prevent the Buy/Sell Exit from being followed if they cause the resulting position to be at 0. This resolves a problem where 2 or more exit orders given in quick succession when using Cancel All Working Orders on Exit, would cause 2 or more exits to actually occur and a reversal in position.
  • 1004 Release Date: 2013-08-03

    • Updated the interface to the Interactive Brokers Trader Workstation software to use the very latest protocol version supported by TWS. Improved the updating of Positions data by manually requesting the positions data every time there is an order fill. This will resolve problems where some users have reported a position in Sierra Chart disappears after about 10 seconds. Financial Advisor accounts now use a new Trade Position data request function supported by TWS which provides continuously updating Position data for all of the accounts. This Sierra Chart version will only be able to connect to Trader Workstation version 9392 or higher.
    • Added a Number of Forward Columns setting in Chart >> Chart Settings to control the number of columns/bars in the forward projection area of the chart.
    • Corrected some issues with the outputting of study data in the Spreadsheet studies that arose in the most recent prereleases.
    • The TT FIX trading service now supports multiple trading accounts. This development is now complete.
    • Changes to simulated order fill price processing. There is no longer a difference with the setting of the fill price between a new order and a resting order unless there is a bar based back test being performed.
    • This version does not support a connection to the TransAct trading service due to a protocol change with GSP. The connection will be supported in the next release when TransAct updates the bridge program to support the protocol change. This change has been agreed upon with TransAct and ensures very accurate setting of the order prices to avoid issues relating to floating-point error. If you are a TransAct user, and you update to this version, you can go back to the prior version by selecting Help >> Download Current Version.
    • Increased the number of historical order fills that are downloaded from LMAX upon a connection, to 45 days from 7 days.
    • Resolved a problem with order handling with TT FIX when there are orders submitted from another program, like X Trader, and they are received over the FIX connection. Previously this was causing a 2nd order to appear. This is now resolved. This issue arose in a recent release.
    • 2nd revision: Added the following Keyboard Shortcut Trading commands: Buy Bid + 1 Tick, Sell Ask - 1 Tick.
    • 2nd revision: It is now possible to use the standard symbol format with the Interactive Brokers trading service for silver futures. The symbol is: SI-######-NYMEX-USD-5000. You will now find this new symbol listed in File >> Find Symbol. Sierra Chart will be able to correctly track and display the current Trade position for that market using this symbol format.
  • 1000 Release Date: 2013-07-26

    • Corrected a problem with simple alerts in the non-CLR version that arose in the prior release.
    • With the TPO Profile Chart and the TPO Value Area Lines studies, improvements have been made to handling of an odd session starting time which is not a multiple of 30 minutes or at 0:00, when using a TPO Letter/Block time period of 30 minutes. There is now the ability to merge the odd sub period which arises from this with the next subperiod, or keep it as a separate subperiod. The study input that controls this is named Merge Odd SubPeriod with Next (Applies to 30 minute letter/block time period). For example, if the TPO Letter/Block time period is 30 minutes, and the chart Start Time is 8:20, and Merge Odd SubPeriod with Next is set to No, then there will be a single subperiod which goes from 8:20 to 8:29:59. The next subperiod will begin at 8:30.
    • Under development: The TT FIX trading service now supports multiple trading accounts. In Global Settings >> Data/Trade Service Settings >> Orders, you can now specify multiple trade account numbers separated by a comma in the Account box. These will be available from the list of trade accounts on the Trade Window.
    • Corrected some issues with simulated order fill handling due to the recent changes to support multiple trade accounts. This was causing various issues with the display of Trade Position data and order fills in a chart for simulated trading.
    • The ACSIL sc.GetStudyExtraArrayFromChartUsingID(int ChartNumber, int StudyID, int SubgraphIndex, int ExtraArrayIndex, SCFloatArrayRef ExtraArrayRef) function has been added.
    • Corrected a problem with the MTGox trading service integration, where the tonce value may not have been set correctly with requests. It is also imperative that your computers clock is accurate to within 10 seconds, otherwise the tonce value will be rejected by MTGox.
  • 998 Release Date: 2013-07-23

    • When using the TPO Profile Chart study on an Intraday chart with a Letter/Block time period of 30 minutes and the starting time of the trading day as set through the Session Times in Chart >> Chart Settings , is set to a time which is not an even multiple of 30 minutes like 8:20, then there will be automatically a separate sub period that goes from 8:20 to 8:29:59 and a new sub period will start at 8:30.
    • Due to the increasing complexity of sub periods with the above change and also the custom sub periods support in the TPO Profile Chart study, the ability to configure the TPO letters through a window is no longer supported. There is now a new TPO Letter Sequence input with the study. It is at the bottom of the list of study Inputs. By default, it is set to ABCDEFGHIJKLMNOPQRSTUVWXabcdefghijklmnopqrstuvwx. The first letter always represents the first sub period for a TPO Profile, whether actually part of the TPO Profile or not. The letters are incremented through for each subsequent sub period in the profile. A sub period refers to the time of an individual block or letter.
    • It is possible since a recent version to change the speed of a chart replay while the replay is running. One problem that has been reported is when the replay speed is reduced, the chart will not continue to replay. It will stop for a period of time. This problem is now resolved.
    • Support for FXCM trading now is only supported with a FIX connection. If you are not using the new FXCM FIX Trading service and have a FXCM account, then follow the instructions in the FXCM Setup Instructions section. The old FXCM interface is now labeled FXCM Historical Data and it only supports historical data. Support for real-time market data and trading for the older interface has been removed and is now discontinued.
    • The connection to CTS T4 now uses a FIX connection. This is much more efficient and has dramatically lower memory use. There are no external third-party API components involved any longer. This is part of our task to remove all external API components for the greatest reliability and performance. When updating to this version or higher, there are some steps you need to follow to successfully use the FIX connection. Follow the instructions in the Using New FIX Connection section on the CTS page. This is essential as the symbols are different.
    • There is now comprehensive support for simultaneously using multiple trade accounts within Sierra Chart. When updating to this version or higher, the trade account is now selected through the Trade Window for the chart or Trade DOM. Open the Trade Window with Trade >> Open Trade Window for Chart. There is a list box on the first tab of the Trade Window which allows selection of the trade account, if multiple trade accounts are supported with the logged in username to the trading service you are using.
    • In the case of LMAX, the account number is now your username. This will cause a problem with determining the current trade positions. After updating to this version or higher, you will need to clear the trade activity data in the Trade Activity Log for each symbol. This only needs to be done once after this initial update. To do this, refer to Clearing Trade Activity Data.
    • Addition to the options for combining Time & Sales records: Do not combine, Combine with same price and type (this is new), Combine with same time and price.
    • Various other new low-level improvements, issues resolved and additions.
