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.

  • 126

    • 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.
  • 125

    • 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.
  • 124

    • 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.
  • 123

    • 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.
  • 122

    • 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.
  • 121

    • 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.
  • 120

    • 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.
  • 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.
  • 117

    • 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.
  • 116

    • 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.
  • 115

    • 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.
  • 112

    • 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.
  • 111

    • 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.
  • 110

    • Supports Software Service Level 10.
    • Improved the downloading of Sierra Chart Historical Daily Data.
    • Improved Chart Downloading and Symbol Status display.
    • Added the Cumulative Sum of Study Line Study.
    • Corrected a problem with TPO/Volume Profile end dates not incrementing on new days.
  • 109

    • Sierra Investment Software now offers Historical Daily Data as an option. For complete details, see the Historical Daily Data page. 5 years of Historical Daily Data for Sierra Chart is provided. This option is great for TransAct users, as an alternative to IB Historical Daily Data, or for users who just need daily historical charts.
    • *Chart Download status and Symbol Errors are now displayed directly on the chart window. This is a major improvement in the communication of these messages. If you have ever experienced a chart not updating for a moment with real time data, now it is very clear why this can happen. This is usually due to a download in progress.
    • A new Options Format is supported for IB. An Example is: ZN-FOP-200612-107-P-ECBOT.
    • A new setting has been added to the General Settings window. You can now choose to display the Alert Log when a Study Alert is added.
    • The Kagi, Renko, and Three Line Break charts have been enhanced. You can now add other studies to them.
  • 108

    • Changes to Getting Quotes on a Spreadsheet: When a # instead of a / precedes a symbol in a Quote Request on a Spreadsheet, the Number Formatting for the cells are ignored. The Quote Values are currently formatted to 5 decimal places. It is planned shortly that the formatting will be based on exchange specifications. If you precede the symbol with a /, then the cell number formatting is applied. Number formats can be controlled by selecting Spreadsheet >> Number Format on the menu.
    • TPO and Volume Profile has been greatly enhanced with new customization options. Additionally, a new dialog window has been created to make it easier when customizing the TPO and Volume Profile study.
  • 107

    • Corrected a problem from version 106 with downloading historical intraday data when using the TransAct service.
  • 106

    • A Lock Scale feature had been added to the interactive scale menu. This simply prevents the scale from being modified while it is locked.
  • 99

    • A new color input has been added for TPO/Volume Profile. As a result, you may have to re-add the study or reconfigure your colors to get correct colors.
    • Volume Profile Gridlines can now be hidden by setting the gridline distance to a negative number. Note that the distance of the gridlines (and ultimately the bars) are still controlled by this number.
    • When using a solid color for TPO's, TPO POC/VA Bar Colors now controls what the POC and VA TPO colors are when the Use Different Colors for POC/VA option is turned on.
    • TPO/Volume Profile Periods are able to be significantly closer to each other than before, this is still controlled with bar spacing.
    • In the TPO/Volume Profile Chart Study, the 1 Day/Custom Days Time Increment (in Minutes) option can now be set to 1440 to represent a whole day increment. For more information on this see the TPO/Volume Profile Study Inputs Documentation Page.
    • With the Volume Study, when there is no difference between the open and close, the bar color is now colored as the average of the 2 colors.
  • 94

    • Corrected minor synchronization and timing issues with replay. If any problems are found, let us know.
    • Documentation for TPO and Volume Profile Charts has been added, refer to the TPO and Volume Profile Chart Documentation for more information about this study.

  • 93

    • Interactive Scaling other than for the constant range scale type now requires software service level 4.
    • Corrected a bug concerning the POC (Point of Control) for TPO and Volume Profile Charts. The POC is calculated based on the following rules: 1) POC is the maximum number of TPO's/Volume. 2)If more than 1 exists, POC is the price that is closest to the mid point of the range [ (HighestPrice+LowestPrice)/2 ]. 3) If there are 2 prices equal distance to the mid point, the side that has more TPO's/Volume is the POC. 4) If both sides have equal TPO's/Volume, the lower price is the POC.
    • Corrected a problem with "Import and Load Intraday Data" with the interpretation of time when the hour for a time was 0.
    • Corrected some problems with the TransAct service integration.
  • 92

    • Made some changes to downloading historical daily data from IB.
    • This version is a pre-release. However, it is known to be stable with DTN IQ Feed, myTrack, and IB. Some issues are being worked out with TransAct still.
