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.

  • The Sierra Chart main window now has optional scroll bars that appear when you move chart windows beyond the main window's edges. This allows you to widen your workspace. You can then use the scroll bars to move charts in and out of view. To enable this option, select Global Settings >> General Settings >> Enable Workspace Scrolling
  • Added the Fill Rectangle Top and Fill Rectangle Bottom subgraph draw styles. These work the same as the Fill Top and Fill Bottom draw styles, but they fill the entire bar from the top to bottom rather than following the contour.
  • You can also use a single fill style if you wish to fill to the edge. That is, only applying the Fill Top style to a subgraph will fill from the subgraph to the bottom of the region.
  • Updated the TD Ameritrade client to accommodate a change they made in the login process. If you use TD Ameritrade you will need to upgrade to this version.

  • Corrected a problem that potentially could occur when downloading data where data may be out of order in the charts. Please upgrade ASAP if you're using version 135-136. If you see any data in the chart where the date and times are out of order, there are two solutions. You can go to Edit >> Export and Edit to view the data and delete or reorder any out of order data. For more information on this, see the Exporting and Importing page. Or you can delete and refresh the out of order data by going to Edit >> Edit Data. For more information on this, see the Intraday Data Editor page. If there is any out of order data, it is most likely to be at the beginning of the file.
  • Corrected a problem where the displayed starting time of bars may be inaccurate when using odd bar periods.

  • All of the Woodies CCI trading club studies are now built in for easy access. To use these, select the "Woodies Built-In" Study Collection from the Analysis menu. The Woodies panel will also be made available shortly as a built-in professionally programmed study. The advantage in using these studies is they provide greater efficiency due to professional programming. They also use safe arrays to eliminate any possible potential for instability. Very shortly our custom DLL study interface which has been used for the Woodies studies will be enhanced to provide safe arrays for custom studies so they cannot cause any instability due to data array access errors.
  • Added 16 float variables and 16 integer variables to the custom studies API. These variables can be used for persistent data storage between function calls. However, they are not saved to disk unlike the StorageBlock.

  • Corrected a problem with the Chart Replay feature where the replay was canceled after reloading the chart during a paused state.
  • The TPO/Volume Profile Split and Merge function has been improved to merge together separate TPO Periods as well. To merge 2 periods, double click between 2 TPO periods. After 2 periods have been merged, you can split them back apart by splitting the TPO chart at the beginning of the 2nd period. To do this, double click on the TPO letter which represents the first time increment for the 2nd day.
  • A new Reset TPO Chart command has been added to the Chart menu. This will reset all the split/merged TPO's back to normal.

• 129

  • Added the SideWinder and Chop Zone Indicator Studies. These are now built in studies, they can be found by selecting Analysis >> Studies on the menu.
  • Corrected a problem from a recent release with the DTN IQ Feed integration where the processing of data was incorrectly handled.
  • Corrected a problem with the Adjust for Split function, which caused Volume to be set to 0 in Intraday Charts.

• 128

  • TPO/Volume Profile charts now support Splitting/Merging TPO's. To do this, simply double click on a TPO letter to split a TPO chart from that point, or double click in between 2 already split TPO charts to merge them back together. Note that although any tool can be used while double clicking, it is best to use the Pointer or Crosshair tool so that no accidental lines/text are drawn.
  • Corrected a problem with the True Strength Index (Ergodic) study which made the study display improperly on updates.

  • Corrected a DTN IQ Feed time-stamping problem. This problem was only from a recent pre-release. This problem could have caused charts not to update.

  • Corrected a problem that could have caused an abnormal shutdown while downloading historical data when using an invalid symbol with the TransAct service.
  • Corrected a problem with TPO and Volume Profile Charts that did not correctly update the TPO Chart when specifying the Start of Day.
  • Corrected a problem with the UseTool DLL function which may have prevented some lines/texts from being added.
  • Added a countdown field to the chart header. This displays the remaining time/ticks/volume/range until the next bar. To use this, go to the Global Settings >> Customize Chart Header window.

  • The port number used when downloading historical intraday data when using the TransAct service, has been changed. Some ISPs were blocking the old port number. This prevented the downloading of historical Intraday data and would cause a timeout error. The port is now 10149.

  • The Pivot Point study has been modified to support R4 and S4 lines.
  • Added 2 new formula types to the Pivot Points Study. The first calculates Open Price Pivot: (Yesterday's High + Yesterday's Low + Current Open + Current Open)/4. To use this formula, set the Formula Type Input to 3. The second calculates pivot points using the standard classical formula's for R3 [PivotPoint + 2 * (High - Low)] and S3 [PivotPoint - 2 * (High - Low)]. To use this formula, set the Formula Type Input to 4.

  • Added a new UseToolEx function for custom DLL studies. Documentation will follow shortly. Refer to the UseToolExample function in studies.cpp.
  • Corrected a problem with the TPO and Volume Profile study which would cause an abnormal shutdown when the study was used.
  • All of the Pivot Points studies have been combined into a single study. You can select the levels you want to display by going to the Subgraphs tab in the Study Settings window for the study. Change the Draw Style to Line for a level to display the line. Or set the Draw Style to Hidden to hide a level.

  • Modified the True Strength Index study based on Bill Blau's ergodic TSI to support the Signal Line MA, Oscillator, and a Multiplier. For more information see the documentation page.
  • A new option has been added to the General Settings Window. You are now able to use any Study Collection as the Default. This setting will automatically assign the selected Study Collection to all new charts. By default, the last Study Collection used before this release of Sierra Chart will be selected. If you have previously defined a study collection named Default, then you need to select it from the list and enable the Use Default Study Collection option to use it.
  • Added support for the opentick service.

  • The Volume by Price study has been significantly modified to display on a regular price chart. Additionally, the profile period can now be specified using Time (fixed period), Number of Bars (fixed width), or Chart Width (dynamic width).
  • The TPO and Volume Profile study has been changed so that a user can now specify what is considered the start of a day. This is particularly useful when charting evening sessions, one could specify the start of a day to be something like 17:00 and TPO/Volume Profile charts would be in increments from 17:00:00 to 16:59:59.
  • The Only Charts in Chartbook in the Chart menu is now a global member. This means that all charts in any chartbook share the same setting.
  • When the Only Charts in Chartbook option is on, and you use the Previous File (-) or the Next File (+) commands, the current symbol is remembered so you can return to it after iterating through all of the symbols in the chartbook.

  • Corrected a problem with the Study/Price Overlay study, Study Moving Average study, GetStudyArray DLL function, and GetStudyArrayFromChart DLL function caused by changes made in pre-release version 119.

  • An option has been added to the "Chart Settings" window: Load Weekend Data. When the option is disabled, weekend data is not loaded. This also applies to real-time chart updating; therefore, if the option is disabled, Sunday night trading is blocked from the chart.
  • Point and Figure charts are now implemented as a study. This study can be found by selecting Analysis -> Studies on the Menu. The study is named Point and Figure Chart. Your existing Point and Figure Charts will open up correctly with this new version. What you will find is that the Point and Figure Study will be automatically added to your chart.
  • A scaling problem with Point and Figure Charts from a recent release has been corrected. This problem may have caused additional space to be shown above or below the chart.
  • If you are using the Pivot Studies or the Previous Day OHLC study, please verify the input "Use this Intraday Chart" is set as you require.
  • The custom DLL study API has been expanded to allow custom chart creation. Several new members have been added to the s_sg structure. For an example of a Point & Figure custom chart, refer to the PointAndFigureChart function in the Custom Chart.cpp file supplied with Sierra Chart.

  • Improvements with historical intraday data for TransAct:
  • Corrected a problem from a recent pre-release where the first 50 minutes from the last date in your chart was not downloaded.
  • Historical data is now compressed which means historical downloads should take less time, up to three times faster.
  • The maximum number of days to download for historical intraday data is now controllable. This can be found by selecting Global Settings >> Data/Trade Service Settings on the menu.
  • The download unit now is based on the Intraday Data Storage Unit setting in Sierra Chart. Previously, data has been downloaded in units of 2-seconds of trading. So now, if your Intraday Data Storage Unit is set to 60 seconds, data will be downloaded in 60-second units.
  • Installed a backup historical intraday data server.
  This avoids any possibility of gaps in the data in case the primary server is unavailable.
  • Collectively these improvements along with the already high-reliability of the historical intraday data service for TransAct, makes this historical intraday data service the most reliable one available.
  • If you are a futures trader and looking for an alternative to IB backfill, we recommend using the TransAct service.

  • In the Intraday Editor, when you press the Delete and Refresh... button and you are deleting less than 10 minutes, no confirmation is shown and the editor is closed.
  • The Spreadsheet for the Stochastic Crossover System example (found on the Analysis menu) now shows a simple method for calculating the Profit or Loss of your system in order to allow you to back-test it. Refer to cells P3 and Q3 for the formulas.

  • Corrected a bug in Renko, Kagi, Three Line Break charts that would cause charts to display extra bars during updates.
  • Added a command in the Edit menu to simply Export an intraday file to a .txt. file without opening the text file in the text editor.
  • Added the option to display VWAP lines historically.

• 114

  • Added a new version of the Demand Index study that follows the more commonly used formula. The existing Demand Index study has been renamed to Demand Index (original).
  • The number of study collections listed per menu column now depends on the screen resolution.
  • A "Cancel Active Backfill Requests on Timeout" option has been added to the Data/Trade Service Settings window for IB. When this option is disabled, Sierra Chart will continue to try to make queued up backfill requests even if there was a time out. Use this option with caution because if the IB server continues to not respond, and our experience is that it will not, then this will lead to extensive delays with chart updating.
  • Corrected a bug where Time and Sales data wasn't stored if the Store Bid & Ask data option was not checked.

• 113

  • Daily data downloaded from IB now only covers the regular trading hours instead of all hours. This corrects a problem where the date of the daily bar may have been one day earlier. This earlier date referred to the starting date of the prior evening session.
  • Support for Ameritrade has been added. Streaming data and Intraday Charts are now supported. Trading through Ameritrade is coming shortly.

  • ADX and ADXR are no longer rounded to integer values. The fractional values are now shown as well.
  • The Pivot Points studies have a new input named: Use this Intraday Chart. When this input is set to Yes , a daily chart is not required and the necessary values are determined from the Intraday chart itself.
  • The Previous Day OHLC study has been reworked and now encompasses Open, High, Low, Close, HL Average, HLC Average, and OHLC Average all on the same study. Additionally, it also has the Use This Intraday Chart option as explained above.
  • Heikin-Ashi Study has been added.

  • Corrected a problem where chart data downloading and updating may not occur after reconnecting to the Transact service when disconnected during an active download.
  • Corrected a minor TPO/Volume Profile bug that would sometimes cause the chart to freeze when volume is not present or too large.
  • Added the %B and Band Width study both relating to the Bollinger bands study.
