Yeah I didnt do through the instructions as I dont have any problem with the process either. Even with that error and another error in the beginin of the process saying the amoun is too small, I still get the bot working fine. I mean It doesnt really make money. It gets less and less everyday but it works at least.

I tried DEMA
and then now I`m trying MACD with the above suggested settings
So far it came down from 0.5 BTC to 0.41 BTC

We`ll see.
Experience is always the most expensive type of lesson you get in life
