Smart question, @mjk2019, i'm just trying different setups yet so wouldn't give you recomendations so far. I'm between 0.01 or 0.02 for alerts and entry points but this is still on testing so if you find something, share. Soon i'll update it with some improvements
@jesuszz4, thanks ;)
I'm using the default options, so far statistics aren't bad. I put a 13% take profit order (with leverage; which means actually 0.13% of price movement in my desired direction) and back-test results are promising.
