The other times you can connect to the SC Data - All Services and still receive the CME real-time data. For Interactive Brokers, added the option Global Settings >> Data/Trade Service Settings >> Trade Settings >> Perform Automatic Trading Account Check for SC Exchange Data Feed. When this is enabled, a connection to TWS will occur automatically as needed when using the SC Data - All Services service in order to receive the real-time CME data if using the lower-priced CME exchange fees.

    • VWAP Rolling study has new period type option "Days - 24 Hour Period" allowing bar-by-bar type of day rolling.
    • New Data/Trade Services to support the new connection model for FXCM and LMAX.
  • 1382 Release Date: 2016-03-16

    • Improvements to DTC Server. This includes the modification of server side bracket orders. The server (when Sierra Chart is used as a server) modifies the attached bracket orders to maintain the original offset they have to the parent order, on a parent fill.
    • Added support for LMAX Stop-Limit orders and resolved a problem relating to the modification of a Stop-Limit order for services that do not support Stop order modification.
    • Corrected a problem with TPO Profile Charts arising from a recent release where Letter/Blocks will be slightly misaligned when using a Letter/Block Price Increment in Ticks Input setting greater than 1.
    • Additional functionality added to the Relative Volume study. Added the Volume Average Type Input which has the options Average Volume and Median Volume. These control how the average volumes are calculated. Added new Study Subgraphs: Average Volume and Average Cumulative Volume, allowing access to the actual average values instead of the Relative Volume percentages.
    • Corrected a problem with the setting of the ACSIL variable sc.IsFullRecalculation arising in a recent release.
    • Corrected a problem from a recent release where some pricing data could potentially be skipped when filling simulated orders originating from Charts/Trade DOMs and modifying trailing stop orders originating from Charts/Trade DOMs. This did not affect back tests.
    • Corrected a problem with the cancellation of Attached Orders when there are linked orders. This arose in a recent release. In some cases some Attached Orders would not be canceled when they should be.
    • Disabled use of server-side OCO orders with the FXCM Trading service because the FXCM server is no longer handling those properly. We expect within the next 30 days to be releasing support for a new connection model for FXCM which will support full server-side OCO and bracket orders and have no account minimums.
  • 1377 Release Date: 2016-03-08

    • Improvements to the automatic downloading of user files from the Web server.
    • Continued improvements with the DTC Server.

    • Various low-level improvements and issues resolved.
  • 1375 Release Date: 2016-03-01

    • There has been a change to the filling of simulated Stop orders. The changes are as follows: In the case where the Bid and Ask prices are higher than the last trade price, then a Buy Stop order will be filled at the last trade price +1 Tick. In the case where the Bid and Ask prices are lower than the last trade price, then a Sell Stop order will be filled at the last trade price -1 Tick.
    • Resolved some issues and made improvements to the DTC Server related to Trade Simulation Mode. The LOGON_REQUEST TradeMode setting is no longer used in the DTC Server. Instead it is a combination of the Trade Account (whether it is a simulated account or not) and the global Trade Simulation Mode setting in the Server which controls whether a trade is simulated or not.
  • 1373 Release Date: 2016-02-26

    • It is now supported to import simulated order fills into the Trade >> Trade Activity Log.
    • New built-in chart bar type in Chart >> Chart Settings: Point And Figure.
    • Added new ACSIL function sc.ChangeACSChartShortcutMenuItemText.
    • Various work with the DTC Server in Sierra Chart relating to trading and market data. The DTC Server for simulated trading is still undergoing testing and there may be some issues that still need to be resolved.
    • Corrected a problem with the filling of simulated orders that originate from the DTC Server where incorrect fill prices may have been used.
    • Improvements to the internal handling and logging of Order cancel rejections and order modification rejections. The DTC Server now will always provide consistent and reliable Order Updates for these.
    • Corrected a problem from a recent release where when there is an order modification reject of a parent order, the Attached Orders were not restored back to their prior prices. This is now solved. This was a problem that developed recently when Attached Orders are modified first before the parent order which is necessary to support the DTC Server in Sierra Chart.
    • Corrected some issues with the Exporting and Importing of Trade Activity Log data.
    • Corrected a problem with the Time and Sales Settings window where it would not close when pressing the OK button.
    • Added new color settings to the Global Settings >> Graphics Settings window to set the text and foreground colors for all of the text based windows. This has been implemented for the Trade Orders and Positions window. Support for these color settings for other windows will be added soon.
    • Added new color settings to the Global Settings >> Graphics Settings window to set the colors of the Profit/ Loss text displays on the Trade Window.
  • 1371 Release Date: 2016-02-18

    • Prevented a usually unnecessary reconnect to the data feed when closing the Data/Trade Service Settings window and also when Symbol Settings are received. Both of these are the result of recent changes.
    • Finished the development of the multithreaded and multiple connection DTC Historical Price Data Server. Only DTC Binary Encoding is currently supported. There are no plans to support other DTC encodings anytime soon. And as a general rule JSON encoding will not be supported with historical price data.

    • Added Point and Figure as a new Chart >> Chart Settings >> Bar Period Type. This is in addition to the study and provides efficient and very accurate Point and Figure bars.
  • 1369 Release Date: 2016-02-13

    • Corrected an integer overflow problem when rounding numbers to an increment when evaluating alert formulas. This may have affected the evaluation of alert formulas when the formula is using large numbers like Volume/Quantity numbers from the main price graph.
    • The Numbers Bars Calculated Values study now supports referencing another Intraday chart for the purpose of accessing chart data that uses different Volume Filtering compared to the chart it is applied to. This feature was added previously but some additional work has been done to it to complete it.
  • 1368 Release Date: 2016-02-11

    • Added the new input setting: "Include Fill Space In Developing Period Width" to the Volume by Price study. When this Input setting is set, the chart fill space is included into the Volume Profile width of a developing period, allowing more space for a developing Volume Profile to be displayed.
    • When saving a single study as a Study Collection, and it is not in Chart Region 1, it will be set to be in Chart Region 2 and the Chart Region height percentages are properly saved with the Study Collection.
    • Added the Automatic option to the Maximum Volume Bar Width Type Input with the Volume by Price study. It will select the period width until it exceeds the window width, at which point it will use the window width.

    • Low-level changes/issues resolved relating to Tick Size, Value Format and Price Multipliers when using the Sierra Chart Exchange Data Feed. when Auto Set from Data Feed was checked in Chart >> Chart Settings, and using the Sierra Chart Exchange Data Feed, the Price Multipliers were incorrectly being set.
    • Continued improvements to New Spreadsheets.
    • Added new rollover date rule for ICE Brent crude oil futures.
    • The connection to TeleTrader is no longer performed through a separate DTC bridge program and is direct from the Sierra Chart main process.

      If you have been using the Relay Server, for the same functionality you need to use the DTC Protocol Server and send a LOGIN_REQUEST message to put the connection into Relay Server Mode. Refer to the updated Relay Server documentation for specific instructions.
  • 1364 Release Date: 2016-01-30

    • Corrected a problem with the Initial Balance study not working on Mondays when the Initial Balance Type is Daily and the time range overlaps midnight.

    • Support for unbundled CME trade data from the CTS T4 trading service. There is currently not an option for this so the CME data from CTS will always be processed as unbundled but an option will be added soon.
    • Solved a price mapping problem from a recent release that existed under certain conditions and with certain values with the Recent Bid/Ask Volume and Current Traded Bid/Ask/Total Volume market data columns.
    • Resolved some small potential issues when submitting an order for a different Symbol or Trade account from ACSIL.
    • In the DTC Protocol Server, the Require TLS (transport layer security) is now supported in properly implemented. When this is enabled, the connection will be encrypted and only an encrypted connection will work. TLS version 1.2 should be used when connecting to the DTC Protocol Server when using TLS.
  • 1360 Release Date: 2016-01-27

    • There is a new option Settings >> Auto Set Alert Text Column Width on the Alert Manager. Toggling this off will prevent the Alert Text column from being automatically sized.
    • Corrected a problem with the CQG Web API trading interface where the price set for order modifications and for order updates for certain symbols (like Silver) was incorrect.
    • Added new ACSIL functions: sc.TimeStringToSCDateTime and sc.IsDateTimeContainedInBarIndex. The documentation will be updated.
  • 1359 Release Date: 2016-01-27

    • Corrected a problem with the CQG Web API trading interface where the price set for submitted orders for certain symbols like silver was incorrect.
    • Other low-level improvements.
  • 1358 Release Date: 2016-01-23

    • Continued performance improvements with New Spreadsheets.
    • Corrected a problem with the TeleTrader data service where when a symbol contains more than two delimiters, it is now properly parsed rather than giving a symbol error.
    • The Trade Account field is now set from open orders sent by IB Trader Workstation.
    • Other low-level improvements.
  • 1355 Release Date: 2016-01-16

    • Corrected problem with New Spreadsheets where when pasting a formula into a cell, the formula result may have been incorrect until the cell was recalculated.
    • Continued performance improvements with New Spreadsheets.
    • Changes to Automated Trade Management where Market orders are not attempted to be canceled when orders are set to be canceled on entries, reversals, and exits because market orders cannot be expected to be canceled. Therefore, market orders are considered in calculations of working orders when combined with the current Trade Position Quantity, even if the variables to cancel orders have been set to TRUE/Yes. This functionality still requires testing. An automated trading system needs to be tested with this version and higher in Trade Simulation Mode to verify it will function correctly. Although we see no reason why any changes to an automated trading system would be necessary. The changes done are to ensure that automated trading works more safely since market orders cannot be expected to be successfully canceled under usual conditions.
    • Added Average Price for Bar study which is meant to normally be used as a hidden study and allow other studies to be based on it to use these average prices as necessary.
  • 1353 Release Date: 2016-01-12

    • Corrected a problem with the Daily OHLC study from a recent release.
    • Continued performance improvements with New Spreadsheets. The GetCorrespondingMatch function has been fully implemented. Additional performance improvements are still being worked on.
    • Corrected a problem when using the Point and Figure XO Graph Draw Type for Reversal bars. The X and O columns now alternate.
