Closed tenebreux closed 1 year ago

tenebreux commented 1 year ago

Describe your environment

Describe the problem:

there is an issue to get the ta lib that's used in all strategies installed on Google's cloud instances. Because of that all the strategies that use ta don't get loaded in freqtrade

Steps to reproduce:

  1. Install docker on google cloud instance
  2. install freqtrade in docker
  3. use any strategy that imports the ta library

Observed Results:

Nothing. It doesn't start.

Relevant code exceptions or logs

Note: Please copy/paste text of the messages, no screenshots of logs please.

your usage is wrong - which is causing the error. EMAPriceCrossoverWithThreshold.py is not a valid python class name - but is a filename. Best read the documentation if it's unclear how to use this.

Regarding your question about ta: Freqtrade does install some technical indicator librararies as dependencies (pandas-ta, ta-lib, technical).

It will however not (and also won't attempt to) install all possible libraries strategies (or also strategy samples provided in this repository). It's the user's responsability to ensure the dependencies are installed (you can usually install it with pip install <yourlibrary>). Often, strategies will also provide a hint about this.

EMAPriceCrossoverWithThreshold.py (or the actual strategy name, EMAPriceCrossoverWithThreshold) is however not a strategy provided here - therefore we also can't provide guidance as to what is ACTUALLY needed.

Thanks for helping Mathias. It's still not working. Can you recommend another strategy i can try?

i still get the same error:

Strategies in this repository should normally load just fine.

Your strategy seems to either use an old interface with new functionalities (namely, using short) - or is not properly implementing the interface.
