This will help select a replacement library to move to from ta-lib.

$ egrep -roh 'ta\..*\(' .|sort -u
gives

ta.ADX(
ta.CCI(
ta.CDLHAMMER(
ta.CMO(
ta.EMA(

ta.MINUS_DI(
ta.MOM(
ta.PLUS_DI(
ta.RSI(
ta.SAR(
ta.SMA(
ta.STOCH(
ta.STOCHF(
ta.TEMA(

Total number of appearances to be changed:

$ egrep -r 'ta\..*\(' .|wc -l

For Finta, only ta.CDLHAMMER does not have a replacement.

I don't think we need to replace talib from the strategies repository to satisfy freqtrade/freqtrade#2509.
talib is a good library - which i think is perfectly fine to include in strategies IF needed (but we should not hard-depend on it as we do now).

We need to remove it from Default / Sample Strategy - and from here "where possible" - maybe.

[hroff-1902]

Than it should be added as dependency here. The custom version with the patch...

The custom version with the patch...

I'm not sure i understand what you'd patch ...

[hroff-1902]

The patch to ta-lib, which is required for cryptos due to low asset price values,
this one:
https://github.com/freqtrade/freqtrade/blob/5e09913e3dc37d2d330be765a48f2722dcc68253/build_helpers/install_ta-lib.sh#L10

[xmatthias]

ah that patch ... - sorry - it wasn't really clear.

we'll also need to keep it in freqtrade (imho) itself - removing ta-lib from the docker image will risk breaking peoples running strategies ... which is ... bad . . .

[hroff-1902]

it's easier to keep it in the docker (because it's build in a more predeterminated environment and conditions) than to keep it a general dependency...

[stigmaknight123]

I think TA modules need to be included in docker images. Some of the strats won't run without them.

[xmatthias]

The main TA modules (ta-lib, technical) are included in the docker images.

There's literally 100ds of others out there - if you need one of these, you can use the docker dependency instruction to include them in your docker image.
