Hello,

I hope you are doing well today,

I was trying to build some custome orderflow using IA but when i would like to build it / import it into sierra there is a following error:

-- Starting remote build of Custom Studies Source files: zn_orderflow.cpp. 64-bit -- 23:04:55

Allow time for the server to compile the files and build the DLL.

Server: https://build.sierrachart.com
The remote build is complete.
The build failed.
zn_orderflow.cpp:11:10: fatal error: SierraChartStudyInterfaceDefinitions.h: No such file or directory
11 | #include "SierraChartStudyInterfaceDefinitions.h"
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

Failed to generate the dll file.

-- End of Build -- 23:04:57


I was looking for this file - SierraChartStudyInterfaceDefinitions.h: but i dont have it in any sierra folder, my Sierra Chart version is 2888, service pac 11

It does not exist...
Your AI hallucinated it.



#include "sierrachart.h"
