I keep trading 0.01 and just building more EAs. I think this is the easiest and smartest way.
As Petko says, you better diversify your number of EAs, and trade smaller lots as 0.01.
So for example instead of having 0.1 lot for on EA, I prefer to have 10 different EAs for this currency pair with 0.01
This way I will catch more possibilities on the market, and I will lower the risk.
