works fine if #strategies > warmups and pairs, else doesn't. something about forkmanager cannot start child process inside child process. I think the logic using fork manager needs to be revisited.

[pangoyal]

@xFFFFF any idea about how to resolve this? It kinda restricts testing of a single strategy on multiple timeframes.

Did you solve this @fubarred ?

[pangoyal]

@lkru No, couldn't. I tried but was taking too much of my time since I am not a python dev. Thought just raise the issue and keep using whatever way it works fine to gain momentum.

@fubarred I have it running now.
downgrade to gekko 5 or:
#35
about fork manager I keep one candle size in backtest config file
