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.

  • 875 Release Date: 2012-07-10

    • When calling sc.GetServicePosition, the only members of the s_SCPositionData structure that are set are as follows: Symbol, PositionQuantity, AveragePrice. For simplicity, position reporting reliability and overall better organization, we have removed everywhere the concept of two sets of position data, the Internal Positions and the Service Positions. There is now is just the Internal Positions. You still see the Service positions on the Orders and Positions window, but that is only used for reference purposes when necessary. You should be using sc.GetInternalPosition from now on. sc.GetServicePosition will only work for live trading. However, we no longer recommend using it. It is not needed unless you set Global Settings >> Trade Settings >> Synchronize Service and Internal Positions.
  • 874 Release Date: 2012-07-07

    • A new option has been added to Global Settings >> Chart Trade Settings to allow modification of working orders on the chart by left clicking the order, releasing the pointer button, moving the order, and then left clicking again to set the new location. This is an alternative to the default click, hold and then drag method.
    • Various enhancements to Attached Orders on the Trade Window. New Stop order types have been added including new Stop-Limit orders. The Move to Breakeven functionality has been enhanced and can now be applied to any of the Attached Stop orders. A Limit Touch Chase order type has been added and can be used as an Attached Order. With this order type, the chase functionality only begins when the order is touched by the last trade price.
    • Various low-level enhancements to the Trade Window.
    • The connection to the Trading Technologies Trading platform service now uses the new Sierra Chart FIX processing engine/functionality. This is still relatively new and is considered still in the testing phases which will be completed over the next week. The advantages of the new Sierra Chart FIX processing functionality is significantly reduced CPU load, the user interface does not freeze when connecting and disconnecting to the servers, and improved logging and troubleshooting.
    • More accurate Intraday chart volume data when using the Trading Technologies Trading platform service.
    • New members added to sc interface for Renko bar type:
      • sc.RenkoTicksPerBar - Set to number of ticks in Renko bar (zero if bar type is not Renko).
      • sc.AreRenkoBars() - Call to check if bar type is Renko, returns zero if not Renko.
    • When in Trade Simulation Mode, the user can now control which order fills are used/displayed on a chart. The choices are Non-Simulation (Live), Simulation, Replay, and Backtest. A new chart header field is displayed indicating which order fills are being used. This setting controls which filled order drawings are drawn, and which fills are used for Trade Statistics and Trading studies on the chart. This is controlled in one of three ways: Trade menu using Trade >> Simulation Fills Source, new ToolBar buttons corresponding to the menu items, or by clicking on the Fill Source field in the chart header.
  • 871 Release Date: 2012-06-27

    • Period sorted trade statistics are shown on the new Period Trade Stats tab of the Trade >> Trade Activity Log. The supported periods include Hour of Day, Half Hour of Day, Day of Week, Month of Year, Daily, Weekly, and Monthly. The statistics are based on the fills being displayed on the Trade Activity tab.
    • Replay and BackTest fills are now treated separately in the Trade Activity Log. This results in four types of fills that are tracked: Non-Simulated (Live), Simulation, Replay, and BackTest.
    • Corrected an issue where the Daily Profit/Loss value on charts and Trade DOMs was not resetting at the start of a new day.
    • Improved upon the processing of Interactive Brokers True Real-Time Bar data. When Global Settings >> Data/Trade Service Settings >> More Interactive Brokers Settings >> Record True Real-Time Data in Intraday Charts is not enabled, then Sierra Chart only supports true real-time data from IB in a chart when using the -TD suffix on a symbol. Everything will be the same as earlier versions. When Record True Real-Time Data in Intraday Charts is enabled, then Interactive Brokers True Real-time Bar data will be recorded in all charts no matter what the symbol, if this type of data is available for the symbol. The way that the recording of the True Real-Time Bar data works is that the chart bars will update every 5 seconds using this true real-time data feed. The time and sales, market depth, current quote data, and last trade price box on the right side of the chart are updated as the standard IB market data feed provides data. So you will have fast updates with time and sales, market depth, current quote data, and the last trade price box and 5 second updates with chart bars.

      The advantage of enabling Record True Real-Time Data in Intraday Charts , is that the Open, High, Low, and Close values for each bar in the chart are now accurate and the Volume for each bar is accurate as well. Whereas when this option is disabled, all of these values are less precise.
    • Various low-level enhancements.
  • 870 Release Date: 2012-06-23

    • Renamed the study High/Low for Time Period to High/Low for Time Period - Extended.
    • Added a new study named High/Low for Time Period. This study is the same as High/Low for Time Period - Extended , except that it does not extend the High and Low lines forward to the end of the session. They only span the defined time period.
    • Improvements with market data processing for the PFG Best trading service.
    • Various low-level enhancements.
  • 868 Release Date: 2012-06-17

    • Second revision: Corrected an issue from the prior release where on a Trade DOM the Daily Profit/Loss value would not indicate trades made during the day before the Trade DOM was opened.
    • Added support for Interactive Brokers to request missing order fills for the past 3 days. This will ensure you have a complete log of fills in the Trade >> Trade Activity Log for fills that occurred when Sierra Chart was not running.
    • When downloading historical Tick data from DTN IQ Feed, quote recording suffixes like -BID will cause the historical bars to be based upon those suffixes.
    • The color of all buttons on the Trade Window can now be configured through Global Settings >> Graphics Settings. The color settings begin with "Chart Trade Window".
    • A new option has been added to the Rectangle, Extended Rectangle, and Line Tool Configuration windows. You can now change the color and style when a Rectangle or Line drawing is touched or crossed by the price bars. The color and style to switch to is specified through the Tool Configuration for the particular drawing tool. Therefore, you can have a Rectangle drawing that is set up to switch to the appearance of another Tool configuration when it is touched or crossed by the price bars. For example, when the bars hit or cross a Rectangle, the outline color/style, fill color, and transparency are set to the settings contained in the selected Rectangle Tool Configuration. This event can trigger one time.
    • When using multiple instances of the Volume by Price study and the profiles are aligned to the right side of the chart, each profile on the right side will be drawn one after another and they will not overlap. There is nothing special to do. This happens automatically.
    • Added new ACSIL member sc.Protect, which when set will disable other studies from getting the study's sc.Subgraph[].Data values. This also includes Spreadsheet studies from accessing the data.
    • Various low-level enhancements.
  • 867 Release Date: 2012-06-08

    • With the Interactive Brokers Trading service, if the True Data market data feed stops, this is detected within 10 seconds and will be restarted.
    • With the Interactive Brokers Trading service, now when the option Record True Real Time Data In Intraday Charts is unchecked, then -TD symbols will work as they did previous to version 863 and non-TD symbols will only record the standard market data feed. TD Intraday charts will only record the True Data real-time data feed when this option is disabled. The standard Interactive Brokers data feed will not be recorded to the TD Intraday data files.
    • Added to ACSIL sc.Input[].DisplayOrder which allows for the display order of study Inputs to be changed without changing array indexes.
    • New option has been added to double extend an Extending Rectangle tool drawing. When double extended, the adjustment of a drawing is done by selecting the top or bottom line instead of the ends of a normal rectangle. If you select the middle, then the entire rectangle will be moved. You will also be able to use the chart drawing menu options to extend rectangle <-> extended rectangle <-> double extended rectangle.
    • Significant improvements to the FIX connection to the PFG Trading service. During the process of connecting, the user interface no longer will go into a freeze condition.
  • 863 Release Date: 2012-06-03

    • This version higher now supports True Data for all IB symbols whether or not -TD is appended to the symbol or not. To use this feature, enable Global Settings >> Data/Trade Service Settings >> More Interactive Brokers Settings >> Record True Real-Time Data in Intraday Charts .

      In this version higher, if you are using -TD symbols, it is essential that you enable Global Settings >> Data/Trade Service Settings >> More Interactive Brokers Settings >> Record True Real-Time Data in Intraday Charts , in order to continue to receive true bar data in these charts. Otherwise, the updating of the charts will be normal updating and not contain true data.

      When you have enabled Record True Real-Time Data in Intraday Charts , the Intraday Data Storage Time Unit will always be at least 5 seconds. It cannot be less and a lower setting will be overridden. In the case where you will want to have an Intraday Data Storage Time Unit that is less than 5 seconds and you wish to use the Record True Real-Time Data in Intraday Charts feature for some charts, you will need to install a second copy of Sierra Chart. This copy needs to have Record True Real-Time Data in Intraday Charts disabled and then you can set the Intraday Data Storage Time Unit to a lower setting in that copy of Sierra Chart.
    • Improvements to the internal calculations of trade position Run-Up/Drawdown and Maximum Open Position Profit and Loss.
    • Continued development with the Trade Window.
    • Various low level additions, changes and improvements.
  • 862 Release Date: 2012-6-1

    • Redesigned Trade Window. Continued development with the Trade Window and Attached Orders is ongoing.
    • When performing a replay back test, the High, Low, and Close values of the underlying data records in the data file are now all used to fill orders. Therefore, no price data is missed.
    • Resolved a problem with IQ Feed where historical Daily data downloaded may not be applied to the proper data file. This issue only potentially affects Historical Daily charts, not Intraday charts, and only occurs if you have a historical Daily chart open for an invalid symbol.
    • Improvements to the Copy Chart Drawings feature to copy chart drawings from one chart to another chart.
    • Added the ACSIL sc.OpenChartOrGetChartReference() function for ACSIL to open a chart matching the provided parameters.
    • Various low level additions, changes and improvements.
  • 859 Release Date: 2012-5-28

    • Interface to the PFG Best Trading service now uses separate connections for data and trading.
    • Added a Grid Lines Subgraph to the Numbers Bars Additional Calculated Values study to control and display grid lines around the values. Set the Draw Style for this Subgraph to Visible to see the grid lines.
    • Various low level additions, changes and improvements.
  • 855 Release Date: 2012-05-17

    • Corrected an issue where when downloading historical Intraday Forex data from the Barchart Data service or Sierra Chart Historical Data service, the bar timestamps were off by one hour. This is now resolved.
    • When applying changes from the Chart >> Chart Settings window, the chart data is only reloaded if you made a change to a setting which requires a reload of the data. Otherwise, the chart data will not be reloaded. This is much more efficient.
    • Corrected a problem from a recent release where when you open a new Intraday chart, and historical Tick data is being downloaded, the data would not be written to the data file with some Data and Trading services. You would receive an "Access is Denied" message relating to the Intraday data file.
    • The TPO Profile Chart study and the Volume by Price study fully support labeling of the Value Area and Point of Control extension lines. This is enabled through the Value Label settings for the Value Area and Point of Control Color subgraphs on the Subgraphs tab of the Study Settings window. When you use Left or Right label alignment, then labels will be drawn on all prior profiles as well as lines that go to the right side of the chart window.
    • Improved the algorithm for identifying whether a trade is at the bid or ask. This is used to set bid volume and ask volume.
    • Added commands to Window menu: Minimize/Restore Detached Chart Windows.
    • The Numbers Bars study has a new Input setting to adjust the width of the background box for each price level in a Numbers Bar based upon the volume of that price level compared to the total volume of the bar.
    • Added Bid/Ask Size Filters to the Time and Sales Window.
    • The Last Trade P/L has been removed from the Internal and Simulated Positions tab of the Trade Orders and Positions window. For this data, use the Trades tab of the Trade >> Trade Activity Log. The corresponding column is Profit/Loss. In order to avoid confusion and inconsistencies, this field has been removed because it was an older field that has been replaced by the data in the Trades tab in the Trade Activity Log and the calculation and matching method was different than we use on the Trades list.
    • Various low level additions, changes and improvements.
  • 852 Release Date: 2012-05-10

    • Added a new Input setting to the TPO Profile Chart study named "Number of TPO Profile Periods". The choices are: "Multiple Periods Fixed by Time", "One Period Of Fixed Time Length at End", "From Start Time To End", "From Start Date-Time + Time Length", "From Start Date-Time To End Date-Time". There are an additional two inputs for setting the TPO Profile Start and End Date-Time in the study Input list as well.
    • Resolved an issue with the Chart >> Perform Future Symbol Rollover feature that prevents chart data for the next contract from being downloaded and the rollover function not completing. This occurs when the symbol being rolled over to, is already being used in another chart.
    • New option in Global Trade Settings to include Open Profit/Loss in the Chart / Trade DOM Daily Profit/Loss display. When turned on, Net Profit/Loss is displayed (NPL).
    • New field in Trade Statistics for Charts tab of the Trade Activity Log, showing Daily Net Profit/Loss (Daily Profit/Loss plus Open Profit/Loss).
    • New Reward/Risk drawing tool.
    • Various low level additions, changes and improvements.
  • 850 Release Date: 2012-05-05

    • When using the Jump Forward button on the Replay Window when the replay is running or when the replay is in a Paused state and you are at the end of the chart, a reload of the chart data no longer occurs. When resuming a replay from a Paused state, and you are at the end of the chart, a reload of the chart data no longer occurs. Both of these improvements make replay easier to use.
    • Set X and Y Constant Relationship scaling mode will now work with TPO Profile Charts and any chart that replaces the main price graph. The internal implementation of this feature has been improved.
    • Various low level additions, changes and improvements.
  • 849 Release Date: 2012-05-03

    • Improved the logic with determining the order of files when joining Intraday data. This is used by the Edit >> Join Intraday Data function and the Chart >> Perform Future Symbol Rollover function. This solves an issue where sometimes files would not be joined in the correct order causing unexpected results in the Intraday data output file.
    • In the case of automated trading, when a trade signal is ignored based upon the automated trading logic, the bar starting Date-Time is now logged with the message indicating the reason for ignoring the trade signal. These messages are logged in Trade >> Trade Service Log .
    • Various low level additions, changes and improvements.
  • 848 Release Date: 2012-04-29

    • Simplifications and improvements with automated trading system Replay Back Testing. There is now one Back Testing option on the Replay Window. It is Accurate Trading System Back Test Mode. This provides a combination of the best accuracy and efficiency. Resolved an issue with Trade Statistics updating within a chart during Back Testing. When starting a Replay Back Test from the Chart Replay window, all prior trade simulation data for the symbol is now cleared and the simulated trade position is reset.
    • New fields outputted to the Spreadsheet System for Trading study spreadsheet. This includes Daily Total Win, Total Lose, Total Trades and Total Quantity Filled.
    • Corrected a problem with trade order modification on charts arising in version 847.
    • We have added new options to the Price Expansion and Price Retracement tools to show the levels in terms of Ticks, Point, Currency, and Risk Reward Ratio.

      The Price Expansion tool can be used to drag between the entry and the stop, and the levels can be used to evaluate different targets. The -100% level is the stop level, while the 0% level is the entry.

      The Price Retracement tool can be used to drag between an entry and a target, and the levels can be used to evaluate different stop levels.
    • Various low level additions, changes and improvements.
  • 842 Release Date: 2012-04-18

    • Corrected an issue with Trade Statistics when a price multiplier is used for price data for a symbol.
    • Trade statistics and the Cumulative Closed Profit/Loss for charts are now consistent among all charts that calculate this data, since they use a common starting Date-Time which is based upon the first order fill for the symbol. The Cumulative Closed Profit/Loss can be viewed by using the Trading: Profit/Loss Text study.
    • Improved the Volume Weighted Average Price study. It can be calculated across any time period. The default is 1 Day. It can be based upon minutes or weeks or any time period as well. 4 standard deviation lines are now provided as well.
    • The number of ToolBar buttons that can be set to a custom time period per bar, has been increased from 10 to 20.
    • Various low level additions, changes and improvements.
  • 840 Release Date: 2012-04-14

    • Improved TPO Profile Charts splitting and merging functionality. Small issues with this functionality have been resolved. Splitting and merging is now much faster. It is now possible to merge Day and Evening session profiles together without any other adjacent profiles being merged in. New commands have been added to the Split and Merge menu allowing removing the leftmost or rightmost merge from a merged profile.
    • Various low level additions, changes and improvements.
  • 839 Release Date: 2012-04-11

    • Trade Statistics, Trade reporting, and Profit/Loss calculations now consider whether an order fill is an opening or closing fill. This makes all of this type of reporting more accurate in case there is missing fill data.
    • In the Volume by Price study, the Extend Value Area and Extend Point of Control inputs now have an option to extend Until Future Intersection .
    • In the No CLR version, there is a menu command Chart >> Link to Quote Spreadsheet , which supports linking a chart to the selected symbol on a Spreadsheet used for quotes. This functionality only works in the no CLR version. The new spreadsheet functionality in the no CLR version is still undergoing development. It is still very new and a lot more work is planned. It is OK to use for a quote board, but it still is not at the level of quality needed for the Spreadsheet studies and the Spreadsheet studies do not work with the new Spreadsheets.
    • Various low level additions, changes and improvements.
  • 836 Release Date: 2012-04-03

    • We have made some enhancements to the new Renko bars Bar Period Type. Refer to the updated documentation in Chart Settings for Renko in Ticks for all of the latest functionality.
    • Resolved an abnormal shutdown issue arising in version 835 with the new performance improvements to the volume at price data.
    • Various low level additions, changes and improvements.
  • 835 Release Date: 2012-04-01

    • Significantly improved the performance of the Zig Zag study when using labels on the Zig Zag lines. When the Additional Output for Spreadsheets input is set to Yes with this study and the Spreadsheet study is on the chart, this study will output the Reversal prices into a separate column on the spreadsheet.
    • Renko Bars: In Chart >> Chart Settings, you will see a new Bar Period Type for Intraday charts named Renko in Ticks. This setting will let you create Renko bars direct from the underlying data in the data file. This is a huge advantage over the Renko Chart studies because there will be less memory use and faster loading times. This is what we recommend using going forward. The other primary advantage is that all of the Volume related studies, especially the Cumulative Delta Bars studies, are all 100% accurate with this new Renko bar.
    • Some low-level improvements with position handling with the various Trading services. The synchronization of the Internal position data and the Service position data, if they are out of sync, is instantaneous now when a full refresh of position data is received from the Trading service.
    • Significantly improved performance with Volume At Price data. Chart data loading times have been reduced about 40%. Memory use has been reduced about 40%. This data is required when using any of the following studies: Volume by Price, Volume Value Area Lines, Numbers Bars, Numbers Bars Additional Calculated Values, TPO Profile Chart. And any other studies requiring this data.
    • Any custom studies that you have developed use the sc.VolumeAtPriceForBars ACSIL member will require code changes. For example code on how to work with the updated version of sc.VolumeAtPriceForBars , refer to the scsf_VolumeAtPriceArrayTest function in the /ACS_Source/studies7.cpp file provided with Sierra Chart.
    • Various low level additions, changes and improvements.
  • 831 Release Date: 2012-03-21

    • Added a complete set of ToolBar buttons and menu commands for chart linking. The menu commands can be found under Chart >> Linking . The ToolBar buttons can be added through Global Settings >> Toolbars >> ToolBar 1-8. You will see them listed in the Chart Linking section of the available ToolBar buttons.
    • Improvements with the handling of positions data with the PFG Best trading service and the Trading Technologies Trading platform service.
    • Added to the Global Settings >> Trade Settings window an option to choose between FIFO or LIFO order fill matching modes. This is used with Trade Statistics and Trades reporting. The name of the option is Use Last In First Out Fill Matching.
    • Various low-level improvements with Trades and Trade Statistics calculations.
    • For Data and Trading services that both historical Minute and Tick data, we now have an improved procedure to download historical chart data from them. When you choose the option to download historical Intraday Tick data, Sierra Chart first will request Minute data if it is a longer-term data request. After that the historical Tick data will be downloaded. The Minute data and Tick data will be joined together, so you have a complete set of long-term history without any gaps. The maximum amount of historical Tick data will be requested and included in the chart data file. Prior to that, the historical data will consist of Minute data. There is nothing special you need to do for this feature. This all works automatically. However, one thing that you can do is select File >> Data/Trade Service Settings on the menu and increase the Maximum Historical Intraday Days to Download to the number of days that you require. One thing to be aware of with this method of downloading is that during the download process, you will not see the bars immediately appear on the chart, they will appear after the download is completed.
    • This version no longer requires Windows Administrator level access when running. However, if you have Sierra Chart installed into a folder on your computer, such as the Program Files folder that prevents a program from writing into that folder, then Sierra Chart will not function properly unless you enable Run As Administrator in the Compatibility settings accessed from the Windows shortcut for Sierra Chart.
    • The sc.UseTool() function has changed slightly in several ways:
      • The s_UseTool.DrawingType member should be used to specify the drawing type instead of setting the s_UseTool.Tool number. The DrawingTypeEnum constants (DRAWING_TEXT, DRAWING_LINE, ...) need to be used instead of the old TOOL_* constants that were assigned to the s_UseTool.Tool field.
      • Old code will continue to work without the above changes, but should be changed.
      • All of the studies that Sierra Chart provides have been updated with the above changes where necessary.
    • Windows 2000 is now supported again. Beginning with a recent release, it was not possible to run Sierra Chart on Windows 2000 and now it is.
    • Various low level additions, changes and improvements.
  • 829 Release Date: 2012-03-14

    • Added support for downloading of PFG Best Historical Tick by tick data. This is necessary for Numbers Bars and high accuracy Volume Profiles when using the PFG Best trading service.
    • Added new menu command: Edit >> Screen Images >> Save Chart Image to File. This command lets you take an image of the chart and save it to a file on your computer system rather than uploading to the Sierra Chart website. Use this command if you do not need to have the image uploaded to the Sierra Chart website.
    • Added the Chart >> Chart Settings >> Advanced Settings >> Align Order Cancel Box to Right option. This lets you align the "X" cancel button on an order line over to the right side of the chart. This may be a more convenient location for some users.
    • Fixed problem with Closed profit/loss in the Trading: Profit/Loss Text study.
    • Added an option to set the connection type in the Global Settings >> Data/Trade Service Settings for TransAct. The choices are Demo, Simulated Live and Live.
    • Various low level additions, changes and improvements.
  • 828 Release Date: 2012-03-08

    • Added a new option to the Time and Sales Settings to combine time and sales records into a single row in the Time and Sales window if the time and price are the same. This is very good at consolidating data.
    • Added in an earlier version: The Trade Activity Log Trade Statistics and Trades tabs now support the capability to display results for all symbols that there is data for the Trade Activity Log.
    • Added in an earlier version: Trade Activity Log now supports fill-to-fill trades in addition to flat-to-flat trades.
    • Various low level additions, changes and improvements.
  • 827 Release Date: 2012-03-06

    • The connection to the Rithmic trading service is now performed in the background so the user interface of Sierra Chart does not freeze during the connection process.
    • Some improvements have been done to the Trading: Profit/Loss Text study.
    • The Trade Orders and Positions window is now a separate top-level window which is accessible on the Windows taskbar.
    • Corrected some issues with the maintaining of Trade Statistics and Trades data within charts. This data is used by the Spreadsheet System for Trading study. And this is also related to Filled orders displayed on a chart.
    • Various low level additions, changes and improvements.
  • 826 Release Date: 2012-03-03

    • Resolved some issues related to Trade Statistics and Trades reporting, and Profit/Loss values.
    • New study added: Trading: Profit/Loss Text . This displays various Profit/Loss values on the chart. These values can be positioned anywhere on a chart window. It is fully customizable.
    • Corrected a problem with the insertion of missing fills when using the FXCM Trading service. Not all fills were inserted. This is now resolved.
    • Corrected a problem submitting orders with a non-hedging FXCM account. Orders which would normally reduce the size of a position were being rejected. This arose in a recent release. This is now resolved.
  • 823 Release Date: 2012-2-23

    • Added the SuperTrend Stop study.
    • Added support for inserting missing order fills to the Trade Activity Log when using the TransAct trading service.
    • Always symmetrical candlestick bars with all high-Low bar thicknesses and bar spacings. (fourth revision)
  • 822 Release Date: 2012-2-17

    • When connecting to the Open E Cry Trading service, a unique identifier is now provided from Sierra Chart. This allows Sierra Chart and the OEC Trader software to be used at the same time. However, it is now necessary to allow Sierra Chart to be used on your OEC account by accessing your account through the OEC website and allowing the Sierra Chart third-party application. For additional help with this, contact OEC.
    • Corrected an issue when using the FXCM Trading service where Synchronize Service and Internal Positions on Connect would not function due to continuous position updating.
    • Added support for inserting missing order fills to the Trade Activity Log when using the FXCM Trading service.
    • Improved trading integration with TransAct. An unusually encountered issue involving fill processing has been resolved.
    • When an automated trading system modifies an order or cancels an order, and there is currently a pending modification or cancellation of that same order, the new modification or cancellation will be queued and will be processed when the prior operation completes. This has always been the case when Sierra Chart is performing its own order management. It should have been the case with order modifications from an ACSIL trading system. However, there was a decision previously that order cancellations should be immediately followed even if there is a pending operation on the order. This is no longer the case.
    • When there is a manual modification of an order, and there is already a pending modification or cancellation of the order, then the modification will be queued and will be processed when the prior operation completes. When there is a manual cancellation of an order, it will be immediately processed as always without regard to whether there is current modification or cancellation on the order.
    • Improved accuracy with Bid Volume and Ask Volume with the Trading Technologies data feed. Testing shows that it is still not 100% accurate, however it should be better.
    • Various continued improvements and development with Trade statistics reporting, Trades reporting, and trade Profit/Loss values.

      In the past Sierra Chart had limited trading statistics reporting. There were a few trading statistics fields maintained for each symbol listed in the Internal Positions tab of the Trade Orders and Positions window. These values would accumulate based upon the received order fills, until they were reset. It was not possible to have them start from a particular Date-Time unless you reset them at that particular time. Although in the case of a back test, they would be automatically reset and would indicate the trading results for the period of the back test. These old fields also would only have knowledge of the real-time fills received. They would not have any consideration of missing fills which were later downloaded by Sierra Chart. In recent months we have developed a new Trade Statistics and Trades tabs on the Trade >> Trade Activity Log window. These displays provide very detailed trading statistics and reporting of your trades for a specified period of time. These tabs also take advantage of missing fills which are downloaded from the Trading service server upon a connection to the Trading server. We have now removed all of the old fields from the Internal Positions tab of the Trade Orders and Positions window. All of the same data can now can be found on the Trade Statistics tab of the Trade Activity Log. In this version all of the development we have been doing in this area over the last few months is now considered finalized and a few outstanding issues have been resolved.

      Additionally, each chart now maintains its own Trade Statistics and Trades list internally when needed. ACSIL trading systems and the Spreadsheet System for Trading study now obtain the trading statistics data they need from this new internal Trade Statistics data and Trades list within the chart. For example, the Closed Profit/Loss you see displayed on a Spreadsheet when using the Spreadsheet System for Trading study comes from the trading data maintained within the chart and it will represent the closed trades since start Date-Time of the chart.
    • If you have an ACSIL trading system that uses the trading statistics data in the s_SCPositionData structure, this includes CumulativeProfitLoss, WinTrades, LoseTrades, TotalTrades and TotalQuantityFilled, then sc.MaintainTradeStatisticsAndTradesData needs to be set to TRUE in the study function in order to have the data for these members maintained.
