Log of Changes and Improvements to Sierra Chart

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

This is not a comprehensive changes and additions log. And it should never be relied upon for such. It only represents a very small percentage of the actual development being performed every day. The vast majority of development is not documented here. Or receives, one small comment after it is all complete. There are not version notes for each version. The main Sierra Chart documentation is updated as needed relating to the changes and additions.

The maintenance of this page has mostly been abandoned by Sierra Chart development for many years due to the difficulty of maintaining it and because users can be incorrectly misled by or misinterpret notes that are made here. This does not change, the development of Sierra Chart which is very active every day and new releases are made nearly weekly or several times a week. The Sierra Chart project is still very active, with extensive development and it remains a very high quality software in the world. The engineering is at the very top of the world.

  • 649 Release Date: 2010-11-18

    • When order is submitted from an auto trade system, the quantity differs from the trade quantity on the Trade Window, and Attached Orders are set to not be used, the Attached Order quantities will remain the same and the trade quantity on the Trade Window window will remain the same.
    • Various small improvements with the TPO Profile Chart study. Additionally, when the Tick Size of the chart changes, the Letter/Block Price Increment input is automatically set.
    • Corrected a problem arising in a recent release where in the Trade Activity Log, when the Maximum Open Position Profit/Loss was read in after starting Sierra Chart, the fields were reversed.
    • Corrected an issue with the returning of internal order IDs when using Attached Orders with ACSIL trading.
    • Changes have been made to the processing of order fills from trading services. This resolves an issue with IB where when order is in a Canceled state and a fill occurs, it will not be disregarded as previously.
    • Corrected a small issue with the calculation of the number of bars used with the Volume by Price study when the Period Type is set to One Period Fixed By Time.
  • 647 Release Date: 2010-11-10

    • Improved the calculation of the TPO and Volume Value Area.
    • Corrected a problem with the TPO Profile Chart study that occurred when volume data is unavailable for a symbol or was unavailable for some bars in the underlying chart. The issue is that there would be no profiles displayed. This is now resolved.
    • The General Settings window now uses multiple tabs. It is more compact than previously.
    • Corrected a problem where the Quantity with the Service Position data for the TD Ameritrade service for short positions would display as a non-negative number. Now short positions use a negative number.
  • 646 Release Date: 2010-11-03

    • The password protection feature for Chart Studies is now complete.
    • All color and font settings for charts can now be specified for each individual chart. All of this is set through Chart >> Graphics Settings.
    • Corrected a problem with the TD Ameritrade service where when your position becomes flat for a symbol, the Service Position data for the symbol would not go flat unless you reconnected the data feed or you manually refreshed the Service Position data. This has been resolved.
    • We have made additional various improvements with the TPO Chart study. The core data construction code has been completely rewritten and is more efficient. It is essential that the Tick Size in Chart >> Chart Settings be set correctly when using this updated version, otherwise it may take a long time to create the TPO chart and it may not appear correctly. Splitting and Merging functionality is now fully supported. To access Splitting and Merging functionality, right-click on the chart and select the TPO Chart Operations submenu. TPO Letter/Blocks can be displayed in their own column. On the TPO Chart Operations submenu select Letters/Blocks In Own Column. We plan to support color coding of the Value Area and Point of Control with the Volume by Price study soon. We plan additional improvements with the TPO study as well.
    • Corrected some issues with the TPO Chart study from version 645
    • Second revision of 646: Added the input New Period At Day Session Start When Using Evening Session (1 Day Period Only) to the TPO Chart study. When this input is set to Yes, the TPO Period is 1 day, and evening session times are used on the chart, then a separate profile will be created for both the evening and day sessions.
    • All unknown error messages and out-of-order data messages have been eliminated from the TPO Chart study.
    • Various low-level improvements.
  • 643 Release Date: 2010-10-22

    • Added a Password Protect option for chart studies to protect viewing and changing inputs, and alternate names for the study and subgraphs. This development is not fully complete.
    • Several important improvements with the TPO Profile Chart study. They are as follows:

      The drawing of columns of TPO Letters or Blocks in TPO Profiles is now linked directly to chart columns which prevents overlapping of TPO Profiles when the chart bar spacing is reduced. The width of profiles is now controlled by altering the chart bar spacing. You can change the chart bar spacing by using the Up and Down arrow keys on your keyboard or by dragging the timescale at the bottom of the chart. Letters/Blocks are now highlighted to indicate the open, midpoint, value area, and point of control rather than using external drawn objects. Splitting and merging is being rewritten and is currently not functional and will be within a matter of days. Volume Profiles have been removed from the study. For Volume Profiles, add the Volume by Price study. It is now fully integrated to work with the TPO Profile Chart study. Further improvements will be made to the Volume by Price study to highlight the Value Area and Point of Control. Displaying TPO Letter/Blocks in individual columns is still under development. The button to customize TPO letters still needs to be added to the Study Settings window. You will notice there is no longer a separate TPO Profile Chart Settings window and the standard input list for studies is used instead now.

      Note: Due to the extensive changes with the TPO Chart study, you will notice that your existing instances of this study on your charts, will be reset to default settings after an upgrade. You will need to go into the Study Settings window for the TPO Profile Chart study and change the settings as you require.

      Refer to the TPO Profile Chart Study documentation for the most up-to-date information and usage instructions about this study.
  • 642 Release Date: 2010-10-12

    • Corrected a problem with OCO order entry from the chart where if the Trade >> Global Trade Settings >> Chart Trade Settings >> Stop Limit Orders: Maintain Constant Offset When Adjusting Limit Price option is enabled, the two prices used for these order types would be set to the second price. This normally should only affect Stop-Limit orders, which use two prices, during order modification. This issue arose in version 639. This problem has been resolved. This is a critical update if you use these order types.
    • Added the option Draw Study Underneath Main Price Graph to the Study Settings window. Removed the option Display Main Chart Graph On Top Of Studies, from Chart Settings.
  • 641 Release Date: 2010-10-04

    • Corrected a problem with IB order handling where order fills may not be detected under certain conditions when using IB managed OCO orders. This problem arose in 639. This is an important upgrade if you use IB for trading.
    • All of the OCO order types that support Attached Orders now support multiple OCO Groups for the Attached Orders.
    • Solved issues with TD Ameritrade and TT market depth data processing.
    • Various low-level improvements.
  • 640 Release Date: 2010-09-30

    • Corrected a problem with stationary text where the text may not display if the Days to Load in the chart was not set high enough. Stationary text is no longer affected by that setting any longer.
    • The following studies have been added: Add-Study Subgraph, Multiply-Study Subgraph. The following studies have been updated: Difference-Study Subgraph, Ratio-Study Subgraph. All of these studies use a single input to the select a reference Study and the Subgraph within the study to use in the calculation. If you have been using one of the existing studies previously, you may need to update the inputs due to the changes.
  • 639 Release Date: 2010-09-25

    • Added full market depth support for TD Ameritrade. This is for both NASDAQ and NYSE stocks.
    • Added the Clear Method Swing Line study presented in Stocks and Commodities magazine to the list of available studies.
    • Improvements with Stop-Limit Orders: Working with Stop-Limit orders is now much easier. The limit price is now automatically set in all cases. It is specified as an offset to the Stop price through the Stop-Limit Order Limit Offset setting on the More tab of the Trade Window for the chart. The value is always specified in Ticks. The default is 4 ticks. This setting is saved with a Trade Window configuration file so you can easily switch between configurations. The automatic setting of the Limit price applies to all Stop-Limit orders including Attached Orders and Trailing Stop-Limit orders. When you modify the stop price of a Stop-Limit order, the limit price maintains a constant offset and is automatically adjusted. When you modify the limit price of a Stop-Limit order, the limit is adjusted independently of the stop. This let you fine-tune the maximum amount away from the stop price that you want your order filled. If you have Stop Limit Orders: Maintain Constant Offset When Adjusting Limit Price in Chart Trade Settings enabled, then when you modify the limit price of a Stop-Limit order, the stop will maintain a constant offset and be adjusted as well.
    • Added an option to File >> Data/Trade Service Settings >> SC Server Settings to select the port to use for the SC Real-Time Server.
    • Added the option Up/Down Coloring For OHLC Bars Based On Previous And Current Close in Global Settings >> Graphics Settings. The default OHLC bar Up/Down coloring is based on the bars open and close.
    • Added a global option to display the time frame on chart tabs for charts that have a Custom Title Bar Name. This option is located at Global Settings >> General Settings >> Display Chart Timeframe on Tabs When Title Bar Name is Used.
    • Fixed a recent issue in the TransAct Interface where symbols entered with lower-case characters would not be found.
    • Fixed processing of historical data in the CTS T4 client for symbols with a format like 1/32, such as ZB.
    • Added members for direct access to common sc.BaseData/sc.BaseDataIn arrays in the ACSIL. These members are: sc.Open, sc.High, sc.Low, sc.Close, sc.Volume, sc.OpenInterest, sc.NumberOfTrades, sc.OHLCAvg, sc.HLCAvg, sc.HLAvg, sc.BidVolume, sc.AskVolume, sc.UpTickVolume, sc.DownTickVolume, sc.NumberOfBidTrades, sc.NumberOfAskTrades.
    • Added a control to the Data/Trade Service Settings for the CTS T4 client to specify the data type (minutes, seconds, or ticks) for downloading intraday data.
  • 635 Release Date: 2010-09-08

    • Corrected various small problems with downloading historical intraday data from the CTS T4 system. Currently data with a resolution of 1 second data is downloaded.
    • Resolved an issue with Attached Orders in Trade Simulation mode where these Attached Orders after they were modified, could potentially fill when triggered by price action even if they were still in a Pending Child state. This issue arose in version 627.
    • Resolved an issue where when using a Price Multiplier on a chart, Trailing Stop orders when modified, would not have have a proper price set for them and could cause an unexpected fill.
    • Resolved a problem from a recent release where the chart tabs may not maintain the same order when clicked on.
    • Updated Sierra Chart to support trading with the latest TransAct AT software. Initially there was a problem in the first revision of 635, but this has been resolved in the second revision.
    • Added an option for automatically saving all open chartbooks at a certain interval. This option can be found under Global Settings >> General Settings >> Auto-Save Chartbooks.
    • With the UDP service, added the OPEN_CHARTBOOK command.
    • Added vertical lines to the Chart DOM to designate click-able areas.
    • The Automated Trading Management logic no longer considers orders in a "Pending Child" state when calculating the quantity of "Working Orders". Only when a child order is transmitted after a parent fills, will it then be considered in the calculations.
    • Improved handling of errors with order modifications sent to live trading services. This also results trailing stop orders continuing to trail even after a single order modification error. With the TransAct service, when there is an error modifying an order, the order will return back to the Open state from Pending Modify and the error result will be shown in the Trade Service Log.
    • Automated Trading management change: When AllowMultipleEntriesInSameDirection is FALSE and there is a Buy/Sell Entry signal, only the actual position for the symbol is considered and not working orders which can establish a position if CancelAllOrdersOnEntriesAndReversals is set to TRUE. For example, if there is a working order which can result in a long position, you are currently flat the market and then there is another Buy Entry signal, the Buy Entry will be allowed assuming other automated trading exceptions do not block it.
    • Various other low level improvements.
  • 631 Release Date: 2010-08-26

    • Updated the TransAct service interface files.
    • With the CTS T4 service, all historical intraday data is obtained directly from CTS T4. All spread symbols are available. There is no extra charge for this service.
    • We have renamed various ACSIL trading structures and functions. The old names still work. The old name followed by the new name are listed here:
      s_scTradingOrderDetails -> s_SCTradeOrder
      s_SCTradingPositionData -> s_SCPositionData
      s_SCTradingOrderInput -> s_SCNewOrder
      SCTrading_BuyEntry -> BuyEntry
      SCTrading_BuyExit -> BuyExit
      SCTrading_SellEntry -> SellEntry
      SCTrading_SellExit -> SellExit
      SCTrading_GetServicePosition -> GetServicePosition
      SCTrading_GetSessionPosition -> GetSessionPosition
      SCTrading_CancelOrder -> CancelOrder
      SCTrading_GetOrderByOrderID -> GetOrderByOrderID
      SCTrading_GetOrderByIndex -> GetOrderByIndex
      SCTrading_CancelAllOrders -> CancelAllOrders
      Trading_ModifyOrder -> ModifyOrder
    • The OpenClose and BuySell members of s_SCTradeOrder are now integer constants rather than strings.
  • 630 Release Date: 2010-08-19

    • Corrected a Volume By Price issue where when using a volume period setting which is equal to a bar period, the volume profiles may not display at the end of the chart.
  • 629 Release Date: 2010-08-18

    • With the Spreadsheet System for Trading study, the chart Price Multiplier is applied to the Profit/Loss values outputted to column J.
    • Corrected issues from version 627 involving Trade Simulation. The problem of simulated Trailing orders not filling has been solved. The problem of the Last Activity date/time not being correct for simulated orders when replaying charts has been solved.
    • Corrected some issues with trade Profit/Loss formatting when a Price Multiplier is used.
    • The Automatic Trendlines study has been modified so that you can specify the High and Low Subgraphs that it is based upon. This is done through the Input Data High/Low Inputs. By default these are High and Low respectively. These can be changed if you are basing the study on something other than the Main Price Graph.
  • 627 Release Date: 2010-08-17

    • Some of the items listed here in this version, were added in previous versions but reported this version. Often this is the case until such time that the new features become stable.
    • When new lines are added to the Trade Activity Log, then the log was automatically saved within about three minutes. The log is also saved when exiting Sierra Chart. The number of days in the log that are saved, based upon the LastActivityTime for the record, is specified under Trade >> Global Trade Settings. If the TradeActivityLog is large, then the saving can be very time-consuming. Therefore it is possible that when there is new activity and the log is saved within three minutes while running Sierra Chart, that Sierra Chart will be in a frozen state while saving the log. We have made changes so the saving is significantly faster and less frequent.
    • Corrected an issue from prerelease 625 where there were issues with loading chart data and this could affect studies relying on the Volume at Price data and could cause abnormal shutdowns.
    • Improvements to the integration of the CTS T4 data feed. Sierra Chart now subscribes to the full tick by tick data feed available on the T4 platform. Also, trades which should be filtered out which affect charting, are filtered out. When the trade is reported by the exchange as having occurred in a spread, it is filtered out.
    • The trade simulation functionality has been internally revised to be more simplified. This lays the foundation for improvements with back testing which includes high-speed back testing.
    • Corrected a problem with high CPU usage from data feed processing that arose with support for Global Symbol Settings and special processing that was done for the IB service. This is now all resolved and this should make a significant difference for users affected by this.
    • Various low-level improvements.
  • 624 Release Date: 2010-08-04

    • Corrected issue with the display of Total Quanitity for orders at the same price level when a Price Multiplier is used.
    • Corrected a problem where global symbol settings were not automatically applied when changing the symbol of chart, if global symbol settings were available for the symbol of the chart.
  • 623 Release Date: 2010-08-2

    • When drawing a 2 or 3 Point Retracement/Extension drawing, the text for each retracement/extension line indicating the price level and/or the percentage is also displayed during the drawing process.
    • Corrected a connection problem with the TT service arising in a recent release where a connection would not succeed to the order server.
    • Due to changes with IB TWS, when modifying certain trade orders, such as Forex trade orders, the modification would fail. Apparently it is now required that the currency code be specified. This issue has now been resolved and the currency code is automatically set. If there are any further problems, let us know.
  • 621 Release Date: 2010-07-28

    • Improvements to chart trading. The Chart DOM now displays the total working quantity of orders at each price level. When modifying orders at a price level where there are multiple orders, a menu appears and you have the ability to choose the order you want to modify. This does not apply to linked orders or when adjusting the price of an order interactively. The menu appears when you modify the quantity, cancel an order, or press the M button on the order line.
    • Added menu items to the right-click context menu of chart tabs. Added Duplicate Chart, Duplicate Chart To Another Chartbook, and Rename.
    • Added Adjust Regions Tool Always Active With Current Tool option in Global Settings >> Tool Settings >> General Settings.
    • Added Draw Highlight Drawings Underneath Main Graph and Studies option in Chart >> Chart Settings.
    • Added Time Range Highlight study.
    • Corrected an issue with Sell Exit Limit Price cell for the Spreadsheet System for Trading study where the price entered was not being used when using Limit orders. This issue arose in a recent release.
    • An option has been added to the Data/Trade Service Settings window for the Transact trading service to disable the connection to the trade server. This will speed up the connect process and can work around a potential issue you may encounter with the Transact AT software.
    • Improvements to Trading Technologies data feed processing.
    • Various low-level improvements.
  • 619 Release Date: 2010-07-22

    • Added Daily Profit/Loss field to the Internal Positions data tab on the Positions Window. This is also logged to the Trade Activity Log. Daily Profit/Loss is reset when a trade is closed and there is a new day.
    • Chart window tabs can now be dragged with your pointer to rearrange the order.
    • The Pivot Points-Variable Period study now forward projects Pivot Point lines into the forward projection area on the right side of the chart. To see the forward projection area, press the right arrow key on your keyboard or the arrow button on the right side of the scrollbar at the bottom of the chart.
    • Corrected an issue with the functioning of the CROSSOVER, CROSSFROMABOVE, and CROSSFROMBELOW Spreadsheet functions arising from changes beginning with version 615.
    • Various low-level improvements.
  • 617 Release Date: 2010-07-16

    • The Pivot Points-Daily study now forward projects Pivot Point lines into the forward projection area on the right side of the chart. To see the forward projection area, press the right arrow key on your keyboard or the arrow button on the right side of the scrollbar at the bottom of the chart.
    • Various improvemnts with the integration to the TT service.
    • Reorganized the Chart Settings window.
    • Corrected a problem arising in 615 with the Crossover functions when used on spreadsheets.
  • 615 Release Date: 2010-07-08

    • Improved the detection of crossovers for studies when Subgraphs have equal values for the beginning values being compared. This applies to the CROSSOVER, CROSSFROMABOVE, and CROSSFROMBELOW functions.
    • Second revision: Corrected an issue where a short position would be reported by one less contract when using TT. Corrected an issue with Scaling Out where existing target and stop orders would not be completely reduced or canceled, when there are multiple fills for a non target/stop order that would reduce the size of the position.
  • 614 Release Date: 2010-07-06

    • Increased the number of characters that can be in a Simple Alert Condition condition formula to 384 characters. This is triple the number of characters previously.
    • Completed the development of the Limit Chase order type. By enabling Use Chase on the Trade Window, limit orders will be converted to chase orders. Whether they are entered through the Trade Window, automated trading, the ChartDOM, or from the chart. The maximum Chase is set on the More tab of the associated Trade Window for the chart.
  • 613 Release Date: 2010-06-25

    • Added the ability to synchronize the Internal Position for a symbol with the Service position in case they are different. It is also possible to create a Internal Position which exactly matches the Service position when a Internal Position for a symbol does not exist. To do this select Trade >> Positions Window. Select the Service Positions tab. Highlight the positions that you want to make the Internal Positions match with (synchronize) and press the Copy Position to Internal Position button. If a corresponding Internal Position does not exist, it will be created.
    • What an intraday chart is opened, loading of the intraday data from the chart data file is now done on a background thread. What this means is that the user interface of Sierra Chart will not be busy or frozen while the loading of data is occurring. This allows chartbooks to take advantage of multiple CPU cores when they are opened. If you find that it takes a long time to load intraday chart data, then refer to help topic 30.12 for things you can do to reduce load times.
    • Added several custom studies from users from the Support Board to Analysis >> Studies >> Add Custom Study >> Sierra Chart Custom Studies and Examples for easy access.
    • The historical stock data downloaded from the Barchart service and the Sierra Chart Historical Data Service is no longer adjusted for dividends.
    • An alternate name can be specified for study Subgraphs. For example, you can use a shorter name than the standard name or a more descriptive name. To set an alternate name for a study Subgraph, open the Study Settings window for the study and then select the Subgraphs tab. Select the particular Subgraph you want to change the name of in the list, and enter the new name in the Short Name box.
    • Added the Stochastic Momentum Indicator study.
  • 612 Release Date: 2010-06-25

    • Added an option vertical grid spacing at Session Start in Chart >> Chart Settings. Using this setting will place a vertical grid line at the start of each session.
    • Added an option to Only Move Out Data On Weekends in File >> Data/Trade Service Settings >> Large Data File Settings
    • Updated Barchart API.
    • Fixed the Hide Study option to work with the Volume by Price study.
    • Improved synchronization in the Study/Price Overlay study. When we determine the appropriate source bar column to copy study or price data from, we now always use the latest bar column in the source chart that is contained within the destination bar column. Previously we would use the first bar column which can be older data.
    • Added a Draw Zeros input to the Study/Price Overlay study.
    • Added the studies Number of Trades - Bid and Number of Trades - Ask.
    • Changed the Move to Breakeven Stop order type so that after you adjust this type of order, the breakeven level is still relative to the parent order fill price rather than the current market price.
    • Added a new order type: Limit Chase. With this order type, if the market moves a way from your entry price, it will be adjusted towards the current market price, but not exceeding specified Maximum Chase value. The maximum Chase value is the maximum offset from your entry price. Therefore it is set to 2, the most your order will be adjusted by is 2.
    • Various low-level improvements.
  • 610 Release Date: 2010-06-08

    • Added an OCO Buy Limit Sell Limit trade order type, along with an OCO Buy Limit Sell Limit (Auto-Set) command.
    • Added the option Round Retracement/Extension Values to Tick Size for the 2 and 3 Retracement/Extension tools. This can be found in Global Settings >> Tool Settings in the tabs for the respective tools.
    • Fixed an issue with the alignment of bar times when the chart option New Bar On Session Start is disabled.
    • Fixed an issue with the Pivot Points-Daily study's Days to Calculate input.
    • Changed the way that the default chart settings are set. Changes to the chart settings of any chart will automatically be used as the settings for new charts, except in the case of settings set through Edit >> Symbol Settings.
    • Updated the interface software for the Barchart service.
    • Various low-level improvements.
  • 609 Release Date: 2010-06-03

    • Corrected a problem with Attached Orders during live trading where if a second fill of a parent occurs during the time the childern are awaiting confirmation from the trading service, the subsequent modification to increase these child order quantities may fail due to the service ID not being set if the service ID was not known at the time of the second fill. This issue only affected services where the Service Order ID is not immediately known, such as TransAct.
    • Support for TT Trading has been completed. More testing is required. TT Trading should not be used on a Live account.
    • The Set as Default button in the Chart Settings window has been removed. The primary default settings for a new chart are now configured through Edit >> Symbol Settings.
    • Various low-level improvements.
  • 606 Release Date: 2010-05-19

    • Implemented processing of IB Order Execution data. This is to support an alternative method for detecting order fills.
    • Various improvements to Trade >> Trading DOM Mode.
    • Added the option Align Trade Drawings Text to Right in Chart >> Chart Settings.
    • Corrected an issue with Attached Orders that arose in version 604.
    • Various low-level improvements.
  • 604 Release Date: 2010-05-14

    • Added Intraday Data Storage Time Unit of 5 seconds. This can be set in the Data/Trade Service Settings.
    • The Buy Stop and Sell Stop and Buy Stop-Limit and Sell Stop-Limit order types now support using Attached Orders. The confirmation window will display and display twice for each Stop order with its Attached Orders.
    • Various low-level improvements.
  • 601 Release Date: 2010-05-06

    • Updated the Rockwell Trading chartbook (Rockwell.cht) with some minor changes and performance improvements.
    • Added support for the Trading Technologies FIX platform. Integration to the data feed has been completed. Trading integration is still in progress.
    • Corrected issue with incorrect Vertical Line drawings date displaying for historical charts.
    • Saturday data from from the Transact service is now filtered out. This is a very important improvement in it is highly recommended that you update soon to this version or higher.
    • Added the ability to fully specify Attached Orders from an ACSIL trading system. These Attached Orders defined from an ACSIL trading system, will replace already defined Attached Orders on the Trade Window for the chart. For an example, refer to the scsf_TradingExampleWithAttachedOrders2 function in the ACS_Source/TradingSystem.cpp file.
    • Additional improvements to the display of Filled orders on charts.
    • Corrected an issue with Numbers Bars coloring arising in 598.
    • Improved the Volume at Price mapping when using derivative charts like the Point and Figure Chart study. This data is used by Numbers Bars and volume related studies.
    • Renamed the Automated Trading variable SendOrderSignalToOrderSystem to SendOrdersToTradeService. It functions identically as before. Keep in mind that even when this is set to TRUE, if you are in Sierra Chart global Trade Simulation Mode, your orders will still be simulated.
    • Various low-level improvements.
  • 599 Release Date: 2010-04-28

    • Revision 2: Removed the Start Date input/setting from the TPO Value Area Lines, TPO Chart, and Volume Value Area Lines studies. This input was useful to start periods at the beginning of the week, the beginning of the month, the beginning of the year when using a Time Period Type of Weeks, Months, or Years respectively. However, this is not necessary because these period types always will start at the beginning of a week, month or year in newer versions. In the case of the TPO Chart study, this input was also used to create a single profile of a fixed period at the end of the chart. You can now use 1 Profile At End of Chart with Specified Length instead.

      When using a Time Period Type of Weeks with the TPO Value Area Lines or TPO Chart studies, it is now possible to specify the TPO Letter/Block Time Increment in Minutes rather than using the default of 1 day.
    • Corrected a problem arising in version 582 with the OEC service where if an order fill event was not received, the Internal Position data would not update and Attached Orders would not be sent. Apparently this was due to an order fill event not being received from OEC. We implemented an alternate method to detect fills as previously was done.
    • Improvements to the display of Filled orders on charts.
    • Various low-level improvements.
  • 598 Release Date: 2010-04-27

    • When a parent order fills and the child order quantities are increased, or when an order in a OCO group fills and its sibling quantity is reduced, the order modifications may be delayed if there is already a pending modification. Corrected a problem where when these order modifications are delayed, the new order quantity may not have been correct. Although, the order modification quantity would never have exceed the original quantity. This problem has now been resolved. This issue arose in version 582 with the introduction of delayed order modifications necessary to support client-side bracket and OCO orders. There would not have been any problem with order quantities involving 1 or 2 contracts or when there was only a single fill. Additionally, this issue was not as a practical matter significant when it came to adjusting sibling orders.
    • Added a new Chart Trade command named OCO Buy Stop Limit Sell Stop Limit (Auto-Set). This will enter both a Buy Stop Limit order and a Sell Stop Limit order in an OCO group where the prices are offset by the Auto-Set Prices Offset from the price that was right-clicked at on the chart. The Limit prices are set by the Stop-Limit Order Limit Offset. This Setting specifies the offset from the Stock price. The Auto-Set Prices Offset and Stop-Limit Order Limit Offset settings can be found on the More tab of the Trade Window.
    • Improved the algorithms for coloring of Numbers Bars. The documentation will be updated soon.
    • Added a new option to Global Settings >> Data/Trade Service Settings >> More Interactive Brokers Settings, when using the Interactive Brokers service, named Use IB Managed OCO and Bracket Orders. By default this is enabled. When this option is disabled, then OCO and Bracket orders will be managed fully by Sierra Chart. Although in this version, Bracket orders are already partially managed by Sierra Chart in that they are not sent until the parent order fills. However, it is expected in a future release, that IB server-side managed Bracket orders will be restored as previously. The reason for this option is that there have been ongoing reports that the IB/TWS system does not always transmit these orders when submitted and they are left in a stuck state. Disabling this option will solve this issue.

    • Corrected a long-standing issue where the right-click menu on charts would not display when the main window, or a detached chart window, had a certain positioning. This was long believed to be some unusual Windows issue, but it turned out to be a coding error with the handling of mouse coordinates.
    • Added a new Chart Trade command named OCO Buy Stop Sell Stop (Auto-Set). This will enter both a Buy Stop order and a Sell Stop order in an OCO group where the prices are offset by the Auto-Set Prices Offset from the price that was right-clicked at on the chart. The Auto-Set Prices Offset can be found on the More tab of the Trade Window.
    • Improved the Sum Charts From List study to correctly set the High and Low of the displayed bars.
