how to modify this project, if i have add a new indicator in ta-lib project and get ta-lib.lib #703
i have add a new indicator in ta-lib and get ta-lib.lib.
what shoud i do about this python wrapper?
ta-lib-python\talib.c seems generated code, how to modify it?
Exciting!
I should probably write that up better, but as a start:
Using the abstract interface, I would think it would already be available.
When I built this wrapper, I used a script tools/generate_func.py and later tools/generate_stream.py to “auto generate” talib/_func.pxi and talib/_stream.pxi.
Those two are in turn converted into the _ta_lib.c file using cython to generate and store the C code so you can compile on platforms that don’t have Cython available.
So to answer your question:
1) I would consider using the generate scripts, but at the very least manually write your wrapper in _func.pxi.
2) use the “make generate” to rebuild the C file
https://github.com/TA-Lib/ta-lib-python/blob/3dd0531bdbe282ffe95d4c74bcabab21c596253e/Makefile#L15
3) use “make build” to build it locally then you can import the local built version for testing by either writing a test for your new indicator and doing “make test” or starting a Python shell and testing it manually.
I’m happy to help your work through this, since we haven’t had a lot of new indicators in awhile!
i get this error when run generate_func.py, how to fix it?

Exception: ACCBANDS not supported by TA-LIB.
Well, you can build it against your new ta-lib with the new indictor in C library, but without the new indicator in Python.
And then add it using the generate script.
Alternatively, add the function manually to talib/_ta_lib.pxd and copy-and-paste a definition for ACCBANDS in talib/_func.pxiand talib/_stream.pxi, which is what the generate script does anyway.
And since someone contributed talib/_ta_lib.pyi we need to add the typed declaration there too.
Alternatively, you can modify the generate_func.py script to provide "defaults and docs" which is what the abstract interface is used for... something like:

Okay, I pushed a change to make it fine without abstract info.
I mean the way I develop it, I use a a ta-lib-python checkout, and I build it locally and run it from the same build directory, so not installed in site-packages.
make build will build it
make generate will make new cython generated C files
if you're on windows, i made an extra change to the generate scripts to support their new install locations.
Running it, I notice this output
cannot find defaults and docs for ACCBANDS
cannot find defaults and docs for AVGDEV
cannot find defaults and docs for IMI
Are these new indicators in 0.6.x that I should support?
the indicator what i want to add is TD Sequential Indicator, i'm not familiar with the whole process of add a new indicator,
so i copy and paste other's volume price trend (VPT) indicator, and got stucked
The "Update the C file" step is only because I like this to be installable without cython available, it's not strictly needed for local development and testing.
i have add new VPT indicator in talib/_ta_lib.pxd, and run generate_func.py, generate_stream.py,
the next step, how to Regenerate the cached talib/_ta_lib.c file using cython?

the indicator that i add was VPT, not IMI
cloudslee commentedon Feb 4, 2025
yeah, it seems that my code was outdate, when i pull remote code from latest git master, it conflict with my local file
cloudslee commentedon Feb 4, 2025
it's ok, thanks
if i want to push my new indicator to ta-lib and ta-lib-python, what shoud i do?
