1. It's called reality-and unless you have a black box-which will work for a short while before meltdown-and you have to understand when it is melting down, not the why.Choose any method you like- there are more skint forex traders than ....... you make up the saying.
2. I have just explained the numbers-you will miss many of the winning trades,beat yourself up about it and take the next 4 losers,then lose your nerve. You will take profits too early too. so P&L will be negative.
3.my last 3 months' trades all small winners- typically 5% ROCE,plus one that is 25% ROCE, same for ther last 36 months-but 2010 I had a losing year and lost the plot somewhat
I hear you. Sometimes just a market shift can cause the black box not to work. I read somewhere where MIT made an auto trading system, but it didn't work for long. I personally used a auto trading program---results were the same. So yep, that statement is correct from my personal experience.
Well I just started my "new system" at the beginining of the month, I haven't missed the winning trades like I did when I was a rookie.
You forgot to address why you think Options are more forgiving.
