Hi, I'm trying to create a custom study and I want to access market data. The source code is the following:

#include "sierrachart.h"

SCDLLName("Volume Profile and Volume Delta")


SCSFExport scsf_FirstAttempt(SCStudyInterfaceRef sc)
{
SCGraphData BaseGraphData;

sc.GetChartBaseData(ChartNumber.GetInt(), BaseGraphData);

SCFloatArrayRef HighArray = sc.BaseGraphData[SC_HIGH];

SCFloatArrayRef LowArray = sc.BaseGraphData[SC_LOW];

SCFloatArrayRef CloseArray = sc.BaseGraphData[SC_LAST];

SCFloatArrayRef VolumeArray = sc.BaseGraphData[SC_VOLUME];

SCFloatArrayRef BidVolumeArray = sc.BaseGraphData[SC_BIDVOL];

SCFloatArrayRef AskVolumeArray = sc.BaseGraphData[SC_ASKVOL];
}


However when I compile it I get the following errors:

-- Starting build of Custom Studies Source files: FirstAttempt.cpp. -- 20:06:23

"E:\SierraChart\CPPCompiler\bin\g++.exe" "E:\SierraChart\ACS_Source\FirstAttempt.cpp" -march=i686 -mtune=i686 -O2 -shared -static -static-libgcc -static-libstdc++ -s -fno-rtti -fno-exceptions -o "E:\SierraChart\Data\FirstAttempt.dll"

SCFloatArrayRef AskVolumeArray = sc.BaseGraphData[SC_ASKVOL];

-- End of Build -- 20:06:25


Also, how do I access the volume profile and ask/bid volume difference bars indicator values?

With the problems we are seeing with the code and the questions being asked, you really need to spend more time studying ACSIL. Refer to this page:
https://www.sierrachart.com/index.php?page=doc/doc_CreatingDLLs.html


SCFloatArrayRef HighArray = sc.BaseGraphData[SC_HIGH];


Needs to be:

SCFloatArrayRef HighArray = BaseGraphData[SC_HIGH];

We do not provide programming help.
