What Is New
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.
- Added sc.TEMA(), sc.BollingerBands() and sc.GetMainGraphVisibleHighAndLow() functions to ACSIL.
- The Spreadsheet System/Alert for Trading study now has more open support to write trade signals to a text file. This is configured through the ExternalTrading.ini file located in your Sierra Chart program folder. To write signals to the text file set the Write Signals to Text File input to Yes, and the Send Orders to Trade Service input to No.
- sc.Subgraph.ExtraArrays in the ACSIL has been renamed to sc.Subgraph.Arrays . ExtraArrays can still be used as well.
- Corrected a problem with the TPO study, where the # character would show for all time increments instead of the TPO letters until one of the letter code options was selected. It is normal for the # sign to show for time increments that do not have a letter defined.
- The Chart Background color can be specified independently under Chart >> Chart Settings.
- The file size for the automatic moving out of data from Intraday data files can be set under Global Settings >> Data/Trade Service Settings >> Large Data File Settings.
- The File >> Find Symbol And Open Chart command is now supported for the SC Forex Data Service.
- Corrected a problem with IB symbols that have a high number of decimal places which caused trading order prices to be rounded off to the incorrect decimal place. This also caused a problem with the modification of attached orders when they are based on the number of Ticks from the parent order. The reason for this problem is because IB sends the tick size in Scientific notation (1.0e-5)for small tick sizes.
- Improved the request of streamer data from TD Ameritrade to avoid cancellation errors.
- Added sc.MACD() and sc.Summation() functions to ACSIL.
- Internally updated the sc.HullMovingAverage(), sc.TriangularMovingAverage() and sc.SmoothedMovingAverage() functions in ACSIL. If your custom study uses these functions you will need to rebuild your DLL.
- For the Attached Orders advanced trading feature, when the parent order is filled the attached orders are adjusted if necessary to maintain the specified relationship to the parent if the parent fills at an unexpected price.
- Added support for downloading of tick data from opentick in addition to minute data that is already supported.
- The Chart Region Headers can now be set to: Visible, Overlapped or Hidden.
- The number of chart regions has been expanded from 5 to 8.
- For the IB trading service it is now possible to attach orders to a parent order. This lets you place stops and targets with an order. These are managed by IB. The quantities will be adjusted and the orders will be maintained even if Sierra Chart is shut down. This is controlled under Trade >> Open Trade Window for Chart >> Advanced >> Attached Orders. This feature is still new, and should only be used on a simulation account until you are comfortable that it works correctly for you. If you have any problems please let us know.
- Study subgraph auto-coloring now supports coloring lines based on +/- values in addition to slope.
- For Studies that support the Moving Average Type input, Smoothed moving average is now an available choice.
- sc.SmoothedMovingAverage() in the ACSIL has been updated, if you are using it in Custom Study functions, be sure to recompile your DLLs.
- ACSIL functions that required passing of arrays for internal use, now no longer require those arrays. The documentation has been updated to reflect this. Existing custom studies will still work. However you can update your code to use fewer arrays.
- Corrected some issues with the Trading interface to Transact as described here.
- Corrected a problem with the information displayed on a modify order confirmation. Modifications were handled correctly, but the confirmation did not display the Modify word.
- Increased the speed of loading Intraday data. (Revision 2 of 272)
- Improvements to the Trade Window. The Internal Position is now shown. The price list boxes have been improved.
- Corrected an issue with Internal Positions relating to the new TWS version.
- The following ACSIL functions have been added: sc.HullMovingAverage, sc.TriangularMovingAverage, sc.VolumeWeightedMovingAverage and sc.SmoothedMovingAverage. Documentation will follow.
- The following ACSIL functions have been updated and require less parameters: sc.CCI, sc.RSI, sc.DMI, sc.ADXR, sc.DMIDiff, and sc.ADX. Documentation will follow.
- Sierra Chart has a much improved Chart Replay feature. There is a new floating replay control panel with buttons to control the replay. You can Start, Pause, jump Back and Forward, and Stop a replay. The jump time is user controllable. You have the ability as always to replay multiple charts. Unlike the prior replay, the starting date and time of the replay is controlled by the chart scroll bar. You simply scroll the chart back to your beginning time and when starting the replay, it will begin with the last bar displayed. When resuming a replay or jumping back or forward, keep in mind that the chart needs to be reloaded and therefore it's important that you load the minimum number of days possible under Chart >> Chart Settings.
- Corrected some minor issues with range bars.
- Corrected an issue with the new ACSIL Subgraph Extra Arrays.
- For the Spreadsheet System/Alert for Trading, some internal improvements to supporting reversals have been made and a new input, named Reset Condition On New Bar, has been added.
- Corrected a problem with Upload Chart with Overlays.
- Corrected issues from the prior pre-release with Woodies and the Extra Arrays. Also corrected a problem where there may have been an abnormal shutdown with certain types of order entry.
- Corrected some issues with the new studies and the revised studies in the prior release.
- Due to changes to the Woodies studies, it is necessary to reapply the Woodies Built-in study collection. For the Chop Zone study, the seven colors can now be set individually and this requires that you remove and re-add the study or modify the Subgraph color settings in order to get the correct colors. If you reapply the Woodies Built-in collection the colors will be correct.
- Woodies studies that require a tick size are now based on the Tick Size setting under Chart >> Chart Settings. If they do not display correctly after upgrading check your Tick Size. You may also need to go to the input settings for Chop Zone and Sidewinder and make sure the Tick size setting there is 0.
- For the Spreadsheet studies, added the fields Open, High, Low, Net Change, and Daily Volume, in the I and J columns. This has caused the limit price inputs cells for the Spreadsheet System for Trading study to have been shifted down. You will need to update your Spreadsheet if you are specifying limit prices. The limit price specification was recently added.
- Fixed a bug with sc.Subgraph.ExtraArrays in ACSIL that prevented them from being allocated on use. If you have any problems with these, please let us know. A working example can be found in the scsf_ExtraArraysExample function in the studies.cpp file.
- The woodies collection source code is now available in woodies.cpp in the ACS_Source folder.
- Woodies studies that require a tick size are now based on the Tick Size setting under Chart >> Chart Settings. If they do not display correctly after upgrading check your Tick Size.
- Made changes to reduce memory usage. It is also now possible to add up to 127 chart studies per chart.
- With the Spreadsheet System/Alert for Trading study, reversals (When the Support Reversals input is set to Yes) do not occur unless there is a position which is opposite of the entry column direction. This is in addition to the existing rules for reversals. For example, if Sell Entry is triggered and you are flat or short the market, a reversal cannot occur. The default quantity will be used and not doubled. Testing of the reversal functionality is being done now, and the reversal feature should still be considered in the testing phase in this release. When using reversals please first test on a simulation account.
- Added the Ichimoku Kinko Hyo studies and study collection.
- Added the Zero Lag EMA study.
- Modified Range bars to not move the last price to the high or low, unless it is outside the high/low range.
- Added Multiply -1 and Chande Momentum Oscillator studies.
- When the Chart Values tool is set to be always on, then it is always on even before beginning drawing with another tool.
- Added a new input to the Spreadsheet studies named Alert/Order Signal Only on Bar Close. When this is set to Yes an Alert and/or order signal will only be given on the close of the last bar.
- When a text drawing is moved or adjusted it now appears in the position of your mouse pointer as you move it around. It also will not prompt for text changes, when you set it in place.
- Added the study Synthetic VIX.
- For advanced custom studies we have added an additional 80 arrays. There are 5 new extra arrays per sc.Subgraph structure. These can be accessed by using sc.Subgraph.ExtraArrays[n][n1], where n can be from 0 to 4 and n1 is the same index value as used with second set of brackets with sc.Subgraph. This required a major change in our custom study interface, if you see any problems with back-compatibility, please let us know. These new arrays also lay the foundation to eliminate passing background arrays to our array operation functions such as sc.ADX().
- For the Spreadsheet System for Trading study, you can choose to use a limit order individually for any of the 4 order signal columns and specify the limit price to be used. The limit prices are specified in column J. In version 262 rev. 2 the limit price cells have been moved down to row 22.
- For the Spreadsheet System for Trading study, the Buy Entry and Sell Entry Counts are preserved between sessions. They can be easily reset by changing them directly on the Spreadsheet.
- Due to some significant changes this version is considered a Pre-Release and is being tested.
- When a logarithmic scale is used and there are negative values in the scale range, a linear scale will be used and the graph will display properly. Negative values cannot be in a logarithmic scale. In the past negative values would cause the graph to not appear. If there are any problems with the display of your charts or studies, please let us know.
- Added commands to the Help menu to download the current version and pre-release version, and update the current running copy of Sierra Chart. This makes updating extremely easy especially if you are running multiple installations.
- Revision 2 of 259: Additional improvements to Range Bars to deliver a constant range according to your setting. This is accomplished by splitting data records and by improved logic when gaps occur.
- Added a command to the Help menu to access remote assistance. This feature lets a support engineer view your desktop and assist.
- Corrected a remaining problem with the constant range scale type.
- Improved the pitchfork tool so the lines are always parallel. There were some certain rare cases where this may not have all always been the case depending upon screen resolution.
- Interactive Scale Move now works with a logarithmic scale.
- Some other low level improvements. Such as an option to automatically open the study settings window when a new study is added. We also plan to allow direct access to the settings window for a study from the chart.
- Fixed a problem that has existed for a while where if more than one Quote Request for a symbol were entered on a Spreadsheet used for quotes, then only the first one would update.
- Corrected a problem with the Upload Chart function arising from the prior pre-release.
- Additional improvements have been made to the SC Real-Time and Historical Forex Data service.
- The constant range scale type has been improved to be stable when auto-centering is off and scale changes are made through interactive scale feature. Other improvements have been made as well. The scale can be moved beyond the values of the last bar.
- Added Historical Volatility Study.
- New recording modes have been added. For complete information see Recording Modes. The suffix -INV can be added to any symbol to get the inverse price. This is very useful for the SC Real-Time and Historical Forex Data service. For example, you can use EURUSD-INV, EURUSD-INVBID, EURUSD-INVASK, EURUSD-INVBIDASK, or EURUSD-INVBAAVG. The SC Forex Historical Data Server supplies historical data only for -INV and -INVBID out of these new modes.
- Added the Moving Average - Triple Exponential study.
- Improvements have been made to the SC Real-Time and Historical Forex Data service.
- The Sierra Chart Trading interface now works with TransAct for approved users.
- Modified the Renko study to handle smaller box sizes for volatile markets.
- The Stop or Limit price for a Stop Limit order can now be automatically set. This applies to order entered through the chart or trade window. To activate this feature select Trade >> Open Trade Window for Chart>> Advanced >> Automatically Set Other Price for Stop Limit Orders. Select the desired unit and enter your value with From Other Order controls.
- Added support for the SC Forex service for levels 3, 4 and 10. This will be available until March 1, 2008.
- Some additional low-level improvements to Tool and Chart Drawing related ACSIL functions were made to provide better support for Kiwi's Copies Lines From Another Chart study.
- Sierra Chart now offers a Real-Time and Historical Forex Data service. For complete information, refer to the Sierra Chart Real-Time And Historical Forex Data Service page. Historical Daily Forex data is and has always been available with the Sierra Chart Historical Data service.
- Some improvements have been made to Range bars, and additional improvements will be made in the next version.
- Better handling of IB True Data symbols. Data for these symbols are continuously restarted every 5 minutes in case the data feed stops from Interactive Brokers.
- Corrected a problem with the Difference (Single Line) study from the prior version.
- Added a study that writes chart bar data in real-time to a text file. The study is called Write Bar Data To File.
- Added a draw style called Candle Outline.
- Optimized and added a study named 'Copies Lines from another Chart' developed by Kiwi, to our custom study list. This can be found under Analysis >> Studies >> Add Custom Study >> Sierra Chart Custom Studies. This study was updated in the second revision of 251.
- The tool related functions in the Advanced Custom Study Interface and Language no longer accept a Line Number of zero. If zero is used, it will be set to 1. This should not be a problem. However, if your custom studies do not function correctly and they are using tool functions, then you may need to update your code.
- Corrected a problem with the Spreadsheet System for Trading study where the position data in column J in a Spreadsheet was not reset to zeros when there was no position data available for the symbol. The Spreadsheet in this case may have showed any previously received position data. Potentially this could have been a minor problem if any formulas relied on this position data until the time that position data became available for the symbol. This was corrected in the second revision of 251.
- Our Intraday data importing function, which imports text data into a Scid or Mnd file has been improved to handle many more data line formats. See the Exporting and Importing documentation page.
- Improved the Candle-Stick coloring logic when open and close prices are equal.
- Corrected a problem with displaying Alert Messages.
- Low level improvements have been made to the Drawing Tool related functions which are part of the Advanced Custom Study Interface and Language. If your advanced custom study uses the sc.UseTool(Ex) or related functions, you may need to rebuild your DLL if you see any problems when using this version or higher.
- Updated the interface to TransAct to properly format the data received for the CBOT contracts that are moving to CME GLOBEX beginning January 14, 2008.
- Improved the detection of Intraday data in an ASCII/Text format. This applies when you open an Intraday text file from File >> Open Historical Chart.
- We have internally updated the RSI studies to be faster. It is recommended if you have these studies in your charts or in study collections, that you verify all your input settings. Some inputs have changed.
- sc.RSI function has been added to the Advanced Custom Study Interface. This calculates the Relative Strength Index.
- Added the Stochastic RSI study.
- Corrected a problem that arose from 245 that prevented the trading functionality from working properly and caused errors.
- Added Bracket Trader Integration for Back Compatibility purposes. We do not provide support for this, you will have to contact Bracket Trader.
- Added the Demarker study.
- Added support for reading number of trades and Bid/Ask Volume when directly opening an ASCII file to chart. Added support for more ASCII data file formats. All of these formats, other than the standard export format for SCID files, can be imported into a SCID file in an upcoming version.
- With the Study Overlay study, the name of the main price graph from the source chart is shown on the data line above the study for easier identification.
- For the DTN IQ feed service, out of order time-stamps in historical Intraday data records are not filtered. This solves the problem that some users had with missing data. We have also advised DTN of this out of order time-stamp problem.
- Corrected a problem from version 242 for the DTN IQ Feed Service that did not filter out data earlier than the last time in the file. This would cause duplicated data. DTN IQ Feed has had time stamping problems with their historical data. This will cause Sierra Chart to filter out some historical data. We are working on removing this filter. This problem arose from the work we did to remove this filter.
