ACSIL (Advanced Custom Study Interface and Language) is for creating custom studies and automatic trading using C++ code.

Unfortunately, ACSIL is not something covered in detail within this handbook. There are some basics to be aware of. The official Sierra Chart ACSIL overview linked below covers many key topics for ACSIL.

Official Documentation:

Build a Custom ACSIL study

First a basic text file containing C++ code is saved with a CPP extension, then the study is built using that file from within Sierra Chart. User can: download examples from Github, examples in the ACS_Source folder, or write them from scratch.

Taking an example file here, modifying it, and then building it for use within Sierra Chart:

  • Navigate to the User/SierraChart/ACS_Source/ folder
  • Open the ACSILCustomChartBars_Example.cpp file
    • Add the following text to the top 2 Lines of the file:
    • #include "sierrachart.h" SCDLLName("Example Studies")
  • Save, ensure the extension is .CPP

Build Study Checklist:

text file containing C++ code saved with a .CPP file extension
The top lines of the file should read:
#include "sierrachart.h"
SCDLLName("Custom Study DLL")

Replace the Custom Study DLL with any name


Next, build the CPP file into a study:

  • Open the main window for Sierra Chart
  • Title Bar: Analysis > Build Custom Studies DLL
  • File > Select Files
  • Select the appropriate CPP file (ACSILCustomChartBars_Example.cpp used as example)
  • Click Open
  • Build menu
  • Remote Build

Apply the study to a chart:

  • Open chart
  • Title Bar: Analysis > Studies (Or click Studies from Control Bar)
  • Add Custom Study
  • expand the SCDLL Name saved earlier (Example was: Example Studies)
  • Select by clicking Custom Chart Bars Example
  • Add
  • OK
