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 less than 25% of the actual development performed every day. 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 has which are not listed.

  • 435 Release Date: 2009-05-18

    • If the Global Settings >> Trade Settings >> Use Internal Position for Charts, Flatten and Reverse option is enabled, then the Flatten and Reverse commands rely on the Internal Position data. This solves the problem where the position from IB simply cannot be determined for some symbols. In this case, Flatten and Reverse were always disabled preventing their use. These commands will now be enabled when a Internal Position exists. However, keep in mind that the Internal Position may not necessarily reflect the actual position with your trading service because it could be out of sync with it. It only knows about trades since you started Sierra Chart.
  • 434 Release Date: 2009-05-15

    • Updated the TPO Value Area Lines study to use a standard time input control for the Start Of Day input instead of entering the number of seconds since the start of the day.
    • Enhanced the Color Bar Based On Alert Condition study with an input to use the alert condition that already exists on another study.
    • Added the sc.GetStudyNameFromChart function to the ACSIL.
    • With the Automatic Trendlines study, added an input named Number Of New Bars Before Auto-Adjustment. This specifies the number of new bars that must appear on the chart before the trendlines re-adjust automatically. This prevents often adjusting of the lines.
  • 433 Release Date: 2009-05-14

    • Corrected a problem where an error message would be shown upon startup indicating that the configuration file is not found. This message will no longer be shown. It would show on a fresh installation of Sierra Chart. This error was simply indicating the configuration file is not present and a default one would be used. However, this error is no longer shown so it does not confuse any users.
    • The Spreadsheet studies will now display the Short Name for studies that have a Short Name set. The names will be displayed in the format: "Short Name (Study Name)".
    • Removed the auto-coloring option Based on Open/Close and replaced it with Same as Base Graph. This will use the same logic as the base graph for determining which color to use for the subgraph. This makes it easy to have the colors of the bars of a subgraph match the colors of the bars of the base graph.
    • Minor corrections related to custom charts made with the ACSIL. These corrections only apply to errors that may have been received with custom charts. If you never received errors with custom charts, then there was never a problem that these corrections, corrected.
    • Removed outlines from the Bid Ask Volume Bars graph draw type.
    • Changed the Volume study to use the new auto-coloring option Same as Base Graph. The input that had been used previously was removed.
  • 431 Release Date: 2009-05-11

    • Corrected a problem with the Donchian Channel arising in a recent pre-release.
    • Corrected a problem where the OrderStatusCode member of s_scTradingOrderDetails was not being set. This applies to the ACSIL Trading functions.
  • 430 Release Date: 2009-05-08

    • The ACSIL Trading function SCTrading_GetLivePosition has been renamed to SCTrading_GetServicePosition to more accurately reflect what it does. SCTrading_GetSessionPosition and SCTrading_GetServicePosition no longer give an error when position data cannot be found. Instead the Position structure object members are simply empty or zero. However, the Symbol member will still be set.
    • The ACSIL Trading functions SCTrading_GetOrderByIndex and SCTrading_GetOrderByOrderID get all the orders now. There is a new member of s_scTradingOrderDetails named OrderStatusCode that indicates the order status. Refer to the updated ACSIL Trading documentation. SCTrading_GetFilledOrderByIndex is now an unsupported function.
    • If you have developed a system study using the ACSIL Trading functions, then you will need to rebuild it under this version or higher and make any appropriate code changes due to the changes that have been made.
    • Added a Moving Average Type input to the Demand Index study.
    • Made an adjustment to the way range bars are expanded when there would be a gap between the bars. Instead of being expanded based on the direction of the bar, range bars are now expanded in the direction of the next trade. This is to prevent the appearance of a high or low value that was never actually reached. Also the close of a range bar that needed to be expanded remains at the last traded price of that bar instead of being pushed to the high or the low of the bar.
    • Fixed a problem with range bar charts not working when the Price Multiplier was set to something other than 1.
    • Added support for BARDATE, BARTIME, and BARDATETIME for Simple Alert condition formulas for studies.
    • Added the ability to set detached charts to always be on top of other windows. To do this, open a chart, detach it from the main window by selecting Chart >> Detach/Re-Attach Chart Window on the menu, and then select Window >> Always On Top on the detached chart's menu.
    • Intraday charts now load data based on the session times set in Chart Settings rather than always cutting the days at midnight. So now if you set the Days to Load to 1 and the Last Date to Load in Chart Settings to a specific date, the chart will show the full trading day for that date according to the session Start and End Times.
    • The PaintBar study has been renamed to Color Bar Based On Alert Condition.
    • The font size for the volume counts in the Volume by Price study can now be set manually through the Volume Count Text subgraph line width. To do this, set the Draw Style for the Volume Count Text subgraph to Visible, and set the Width/Size to a number greater than 5. A Width/Size of 0 will adjust the size of the font automatically.
  • 428 Release Date: 2009-05-06

    • The ACSIL sc.SCTrading_BuyExit and sc.SCTrading_SellExit functions would not necessarily flatten the position if an order quantity was not specified. The default quantity was 1 previously. Therefore at most they would give an order of quantity 1. By default the order quantity is now zero which means they will flatten the position. If the order quantity is specified, and it does not exceed the quantity necessary to flatten the position, that quantity will be used. Otherwise the position will be flattened.
    • The ACSIL Trading functions, data structures and documentation have undergone numerous revisions. Refer to the current documentation. It is necessary for you to rebuild your custom studies that use the ACSIL trading functions. You may encounter compiler errors. When you do, refer to the updated documentation for the function, structure member or constant you are using to find out what changes you need to make.
  • 427 Release Date: 2009-05-04

    • There have been changes to the types used in the ACSIL trading structures. When using this version or higher it is necessary to rebuild your study functions that use the ACSIL Trading functionality, that were built with prior versions in order to work properly on this version and up. Due to type changes, you may also need to make code modifications. Several SCStrings have been converted to either doubles or ints. The Trading From an Advanced Custom Study documentation has been updated on May 5, 2008.
    • Corrected a minor problem with the Pivot Points-Variable Period study when using evening session time settings.
    • Various other low-level improvements.
  • 425 Release Date: 2009-04-30

    • Corrected some issues with the Automatic Trendlines study.
    • Added the Average Fill Price (AvgFillPrice) to the ACSIL trading s_scTradingOrderDetails structure.
    • The ACSIL Trading functions and structures have been internally improved. When using this version or higher it is necessary to rebuild your study functions that were built with prior versions in order to work properly on this version and up.
    • Various low-level improvements.
  • 423 Release Date: 2009-04-24

    • Filled Orders can now be displayed on the chart in Chart Trade Mode. The settings for this feature can be found in Trade >> Global Trade Settings in the Chart Trading Section.
    • The Text Size for the Volume By Price study has been fixed so that it resizes to the bar size as it did in previous versions.
    • A problem with trailing stops arising in a recent pre-release, has been corrected.
    • Our simple alert feature for studies has been enhanced. It is now possible to use an Excel-style formula for alerts. Alert condition formulas can refer to other studies on the chart by using this syntax: ID#.SG# where # is the study ID number shown on the right side of the study in the list of Studies to Graph and the number of the subgraph. To use an enhanced alert condition, precede the formula with an equals (=) sign. Documentation is being worked on. An example would be =CROSSOVER(ID1.SG1, ID2.SG1). This would give an alert when the first subgraph of study with ID 1 crosses the first subgraph of study with ID 2.
    • Added a Copy Symbols button to the Alerts Log. When this button is pressed, it will create a list of symbols which have alert lines in the Alerts Log that can be pasted anywhere.
    • Added a new study subgraph Draw Style pair named: Transparent Fill Top and Transparent Fill Bottom.
  • 421

    • Added a Copy Command to the Trade Orders Window and to the Positions Window.
    • When downloading Historical Data from the Barchart Real-Time and Historical Data Service, the chart is updated as the data is being downloaded.
    • Added a new option to the Study Settings Window to save the current settings as the default for newly added instances of the study. This option is named Save these settings as the default. There is also a Reset Defaults button that will clear these saved default settings.
    • A Length input has been added to the Swing High and Low study.
    • Added a new input to the Envelope Study to support a fixed value.
    • A new function has been added to the ACSIL Trading Interface, sc.SCTrading_GetFilledOrderByIndex(), that is used to get order details of orders that have already been filled.
    • When the connection is lost to the TransAct trade engine, Sierra Chart will retry every 20 seconds for 5 times, then every 1 minute for 55 times and stop. In no case will the Message Log open up indicating the retries during this time. Sierra Chart will not attempt to reconnect to the Transact trade engine if it was never able to successfully connect previously. If Sierra Chart has difficulty reconnecting to the Transact trade engine, then be certain your Transact AT software is fully up to date as Transact has resolved some issues with this.
  • 419 Release Date: 2009-04-10

    • A new input has been added to the Spreadsheet Study to cancel all orders on a reversal. This input is called Cancel All Orders on Reversals. The ACSIL Trading interface has been enhanced to support the same functionality. The variable that controls this is called sc.CancelAllOrdersOnReversals.
    • For the Spreadsheet System for Trading studies, cell J29 is now used to flatten and cancel all working orders. Be sure to update your formulas if you were using this cell for calculations before.
    • Corrected a problem where when duplicating a detached chart, it would not show.
    • Text drawn with the Stationary Text tool is now Stationary along the Y-axis.
    • Added controls to the Global Settings >> Spreadsheets Settings window for controlling options affecting the interface to Excel.
  • 418 Release Date: 2009-04-08

    • Support for trading through GAIN Capital (OEC Trader) is now available. This is our initial release. It should only be used with the OEC simulation server until you are certain that it works properly for you. Any problems or questions should be directed to Sierra Chart Support on the Sierra Chart Support Board.
    • A new study input has been added to the Renko Chart titled "Draw Renko Boxes on Bar Close". This tells the study to only draw Renko Boxes when a bar in the underlying base data has completely closed.
    • The Trade Orders Window and Positions Window now use color coding.
    • Downloading Historical Data from the Barchart Service is much faster.
  • 417 Release Date: 2009-04-03

    • When you double click on a Highlight chart drawing in the middle, it will move it instead of adjusting it.
    • Added new calculated values to the Chart Calculator Tool. These can be found under Global Settings >> Tool Settings >> Calculator.
    • Corrected a problem from the prior release where this error was given: "c_Chart::GetWndPtr: c_Chart object doesn't have assigned Window." This has now been solved.
    • Added the Automatic Trendlines study.
    • Added to the Time and Sales settings window, controls to highlight lines based on the specified price or volume conditions.
  • 416 Release Date: 2009-04-02

    • Corrected a problem with the sc.Parabolic ACSIL function where it would not function properly when used with the Watcom compiler.
    • Added the study function scsf_StudyPriceOverlay to Studies6.cpp. This function works like the Study/Price Overlay study. It does not copy all of the settings of the source study, as the built-in version. We have provided it as an example of how the Study/Price Overlay study works.
  • 415 Release Date: 2009-04-01

    • Corrected some issues that arose with version 414 with downloading historical data from the Barchart Real-Time and Historical Data Service.
    • Corrected a problem from version 414 with the Commodity Channel Index not being back compatible with existing study collections.
  • 414 Release Date: 2009-03-31

    • The Spreadsheet System for Trading study has been improved. There is now a cell that allows you to disable all trading, this is located in cell J28 and titled Disable Auto Trading. There are also 2 new cells that record the last DateTime of Entries and Exits. These cells are located in cell J42 and J43 respectively and titled Last Trade Entry DateTime and Last Trade Exit DateTime.
    • The ACSIL has a minor improvement. sc.PlaySound now displays a more descriptive alert line in the alert log. Additionally, Go To Chart now works with alert lines generated from sc.PlaySound.
    • Historical intraday data for the SC Real-Time Data (DDF) service is now downloaded directly by Sierra Chart instead of using the Barchart API.
    • Added the ability to quickly change the color of chart drawings. To do this, right click on a chart drawing, and select one of the colors from the Color submenu.
    • Settings for the line style and width were added for the Linear Regression tool.
    • Added the Save Message Log To File option in the General Settings that will save the log to a file. The file is saved in the Logs subfolder where Sierra Chart is installed to. The saving of the log is automatic once this option is checked. The file is updated every time a new message is added.
    • Added a new study collection for the Buffy Trading system named Buffy 2. This is installed when you choose to install the Additional Files in the installer.
    • When using the chartbook and window tabs, the active tabs are now highlighted.
  • 413 Release Date: 2009-03-20

    • Added support for Financial Advisor accounts trading through Interactive Brokers. To fill in your Financial Advisor information, select File >> Date/Trade Service Settings on the menu and go to the More Interactive Brokers Settings... section.
    • Removed the Immediate and Good Till Date/Time expiration types from the TransAct client because they are not known to be supported.
    • If the bid and ask are both the same as the value of a trade, then the volume of that trade will be split evenly into the bid volume and ask volume of the bar so that the sum of the bid volume and the ask volume will equal the total volume. Previously the sum of the bid volume and the ask volume had both been set under this condition so that the sum ended up being greater than the total.
    • A Zoom In tool has been added.
  • 412

    • The ACSIL Trading interface has been improved. A new member variable has been added, sc.GlobalTradeSimulationIsOn, that is set to TRUE when a user has enabled Trade Simulation, and is set to FALSE when the Trade Simulation is disabled. Another new member function has been added to modify orders. The declaration for this function is int sc.SCTrading_ModifyOrder(const SCString& OrderID, s_scTradingOrderInput& OrderModifications);.
    • Fixed an issue where the replay control window did not work on detached charts.
    • Added Good Till Canceled, Good Till Date/Time, and All or None order options to the TransAct trading interface.
    • Corrected a problem where if a text file did not contain the carriage return character at the end of a line, and only had a line feed character, the lines were not read in correctly. This applies to historical text files and when importing intraday data. Files created by Sierra Chart were not affected.
  • 411 Release Date: 2009/03/13

    • This version includes the latest TransAct API.
    • The message log can now be minimized. If an important message is added to the message log while it is minimized, the log window will flash in the task bar.
    • Corrected a problem from a recent release where stopping a replay causes high CPU usage when using Trade Simulation and when disconnected from the feed.
  • 410

    • A new member varable has been added to the sg struct for ACSIL trading, sc.SupportAttachedOrdersForTrading. When this variable is set to TRUE, the orders that are entered from the ACSIL trading interface will use the Attached Orders that are specified from the Trade / Settings Window of the chart in which the ACSIL study is applied to. This only applies to Buy/Sell Entries, Exits can not have attached orders attached to them.
  • 409

    • Added an option for the IB trading service to multiply stock data volume by the specified multiplier. By default this is 1. This option can be found under Global Settings >> Data/Trade Service Settings >> {Service set to Interactive Brokers} >> More Interactive Brokers Settings.
  • 408 Release Date: 2009/03/10

    • Added an Import function for importing a list of symbols from a text file, to the Global Settings >> Intraday File Update List window. Each symbol needs to be on its own line in the file.
    • Added an option for Simple Study Alerts to Evaluate on Bar Close.
    • This version has significantly reduced CPU usage. Especially when loading a large number of bars in a chart.
  • 407 Release Date: 2009/03/09

    • Corrected a problem from a recent release where some Trade Position related prices would sometimes not be set correctly for Simulated Trading. If you are using Simulated Trading, it is important to upgrade.
    • Automated trading now takes into consideration multiple attached orders when calculating the Internal Position with working orders quantity.
  • 406 Release Date: 2009/03/04

    • Updated interface files for Transact and the Barchart Real-Time and Historical Data Service are included.
  • 405 Release Date: 2009/03/03

    • Corrected a problem with the displaying of Compiler Output on the Build Studies DLL window.
    • Various low level improvements.
  • 404 Release Date: 2009/02/27

    • Corrected a problem with the Volume Weighted Average Price study where the last bar would produce incorrect results for the VWAP line.
    • On the Associated Symbols List there is now an Import button that lets you import symbols from a text file. Each symbol should be on its own line.
  • 403 Release Date: 2009/02/26

    • Created a new Buffy studies template. This is very fast and reliable compared to prior templates that were available.
    • Corrected a problem with the output displayed on the Build Studies DLL Window.
    • The problem with abnormal shutdown when using the IB service experienced by some users, apparently is due to extreme out of range trade position values received from the IB service. We now reject those values and this should resolve the problem.
    • When the connection to the TransAct trade server used for trading functionality is lost, a reconnect will automatically be performed unlike prior versions since support for the new TransAct pricing API. Working orders and Positions are also refreshed after the connection. It is important if you are using the trading functionality in Sierra Chart with Transact that you update to this version. Additionally, Transact has released a new trade engine file to solve some reconnection issues. That is available on our Support Board.
  • 402 Release Date: 2009/02/24

    • This version has new API files from Transact. This should resolve the problem where that data feed from Transact stops and does not resume. If you still have a problem be sure to let us know and we will contact Transact about the issue.
  • 399 Release Date: 2009-02-19

    • Fixed a problem with the Volume Weighted Average Price study that arose from a recent release.
    • This version solved the problem where some users would experience an abnormal shutdown when using IB. This relates to the code that processes Position Data from Trades. We are still in the process of determining the exact cause and have disabled position data processing. This will be reactivated in the next release. Therefore, in this release you will have to rely on the Internal Position data. Flatten and Reverse may not work.
    • Color Coded the data feed status window.
    • Added an associated symbol list feature for charts. This lets you add a list of symbols to a chart and be able to cycle through them on that chart. This can be found on the Chart Menu.
    • Added High/Low of Day study. This study will mark the high and the low of the day.
  • 397 Release Date: 2009-02-17

    • Improved the function for the Interactive Brokers debug logging.
    • Corrected a problem with the names shown on window tabs.
    • Color coded the data feed and program status window.
