Hi Gregor,
I reviewed your FXblue results. I suggest keeping AUDCHF.pro and USDCHF.pro with current lot sizes. Change other lots sizes to 0.01. Each weekend sort by Net pips, largest to smallest. Then look at Symbols. Pick the ones that are in profit with profit factor greater than 1.2 and increase their lot size to the risk level you are willing to accept. Move all other assets to 0.01 lots. repeat each weekend. This is how I do it. I do not expose my account to more than 3%. For example, if I find 4 assets that have profit for last week and profit factor greater than 1.2 I set each of their lot sizes to represent 0.75% of account balance.
You can follow my topic from start to current status to get an idea of how I trade the robots. The robots I trade are my own but the workflow is the same:
Hope this will help get you going!
Alan,
