I recommend an ubuntu or macOS setup for dev with TA-Lib... WSL on windows would also do.

It should work on windows native, but I do not actively use it for development anymore (I use a windows VM only for packaging and running ta_regtest).

mcpp.exe

From https://mcpp.sourceforge.net/download.html

For convenience, I did embed the .exe in the repos https://github.com/TA-Lib/ta-lib/tree/main/src/tools/gen_code

how to use gen_code

Just a heads-up, this is not trivial, but if you are willing to spend a few days to get started, I am here to help (when asking a question, consider putting your latest code in a fork so I can review all changes instead of going back and forth with small code excerpt).

gen_code generates the ta_XXXX.c files (and more). The function signature (the API) is defined in C in one of the "table file": https://github.com/TA-Lib/ta-lib/tree/main/src/ta_abstract/tables

Best way to start is to cut&paste&rename an existing "similar" function in a table, rebuild and run gen_code... and verify that a new ta_func/TA_xxxx.c file is created.

You then modify the non-generated portion of TA_xxxx.c file to put your own code. You can always add/remove parameters by changing the table and rebuilding+running gen_code.

To test the logic, rebuild ta_regtest after a gen_code. Again, cut&paste an existing "similar" function for testing.
