I downloaded the source code for the COT study from here. https://www.sierrachart.com/AdditionalFiles/UserContributedACS_SourceCode/COT.cpp Then I followed these instructions for building a custome study from source code. How to Build an Advanced Custom Study from Source Code However. I'm getting an error after I click Remote Build to compile the study. I'm running version 2086. The text of the error is pasted below. TEXT OF ERROR -- Starting remote build of Custom Studies Source files: COT.cpp. 64-bit -- 09:51:14 Allow time for the server to compile the files and build the DLL. The remote build did not succeed. Result: COT.cpp:2:30: fatal error: scstudyfunctions.h: No such file or directory #include "scstudyfunctions.h" ^ compilation terminated. -- End of Build -- 09:51:16

UPDATE: I changed the following line of code: #include "scstudyfunctions.h" to read #include "SCStudyFunctions.h" That led to a new error. ERROR TEXT -- Starting remote build of Custom Studies Source files: COT.cpp. 64-bit -- 10:42:38 Allow time for the server to compile the files and build the DLL. The remote build did not succeed.

You could try this instead: std::string Bufferas = sc.HTTPResponse.GetChars()

Thanks. Problem solved with some help from a friend. I changed the 2 instances of std::string Bufferas = sc.HTTPResponse; to std::string Bufferas = ""; Buffer.Append(sc.HTTPResponse);

I am having a similar issue as indicated above. -- Starting remote build of Custom Studies Source files: COT.cpp. 64-bit -- 16:09:38 Allow time for the server to compile the files and build the DLL. The remote build did not succeed. Result: COT.cpp: In function 'void scsf_TradingLevelsStudy(SCStudyInterfaceRef)': COT.cpp:427:47: error: 'DAYS' was not declared in this scope 427 \| SCDateTime DataDateLessOne = DataDate - 1*DAYS; \| ^~~~ -- End of Build -- 16:09:42 Did anyone find a solution for this issue?

The error is here on line 427: SCDateTime DataDateLessOne = DataDate - 1*DAYS; Change it to: SCDateTime DataDateLessOne = DataDate - SCDateTime::DAYS(1); This was documented as a change here: Required SCDateTime Changes for ACSIL

Hello, I followed your instructions, I corrected all the mistakes and finally I have successfully compiled the COT, but it still doesn't work. There's a log in Sierra that says: "requesting data from quandl server". Don't you please know what's the problem?

Study accesses COT data from Quandle.com ( basic free account needed for study )

Personally, I also had difficulty getting this study to work. After I finally did, it didn't give the data I was looking for. I use IQFeed and get the CoT data from them. Additionally, they have a lot more history.

I do have Quandle.com account and Quandl APIkey, but it doesn't work anyway.

So try to contact the author of the study via DM (or email) COT / Commitment of Traders \| Post: 170793
