I get the same error using the default BTC-USD trading pair also.
Thanks for pointing this out. What is the granularity set to? I’ve not tested it at granularity values other than 300 (5 min) and 900 (15 min). I’ve also not tested with pairs other than USD-BTC. I’ll look into this a bit. It’s a new script and could be a little buggy.
As far as I can tell, this is caused when no strategies have a profit greater than zero.
When that happens, no strategies "beat" the default best_strategy
of None
in find_optimal_strategy
.
This None
is returned up the stack to main
, which passes it to iterate_signal
, which can't subscript it, thus the error.
Oh interesting. That makes sense. I didn’t consider that potential failure point. Will update the script to correct that. Thanks for pointing it out.
OK, I fixed the NoneType
issue in the helper_monkey.py
script. It will now default to a {'buy':1.0, 'risk':1.0}
strategy in the event that an optimal strategy can't be found.
When I have a little bit more time, I think I am going to add a feature where the user can override the strategy optimization and set a default strategy of their choosing.

got this after filling API key details and issuing ./run_bot.py command. I'm using XLM/BTC trading pair. 0 XLM, small amount of test BTC on account.
