@Andi-I first look at win/loss % for the last 10 trades, then I look to see how many pips did each trade move, and how much profit/loss occurred for each trade. Highest win%, highest pips, and highest profit/lowest loss =0.04 and then I take the next best and give it 0.03 and so forth. Of course, this all occurs for each asset pair. So as I am trading 12 different assets right now, there are only 12 EAs that have the 0.04 lot size (1 for each asset pair). Hope this helps explain my thought process better.
