With regards reporting percentage profits HC, please find me someone else or a link anywhere on the web who/which expresses return as percentage of capital risked.
Using this approach, if I enter a trade with a 20 pip stop and end up making 40 pips, I've made 200%. Looking back at my returns over the last year, I had one month when I was up 500%, using your calculations. However, because I risk less than 1% of my ENTIRE trading pot per trade, it "only" amounted to +20% on my entire account.
It doesn't matter if you're running 4 or 400 other systems on your pot, you have to state the return for the overall pot. I guess that the question is this -
should someone devote 100% of their pot to your strategy?
I think we all know the answer is no, because you've seen things in your backtest which have made you hesitant. You know, the backtest which you ran and won't reveal any results for.
