@Florian ... Everyone has a right to their own opinion and view.
However here is more to my view. imagine two traders, A and B
Trader A has 10% returns per month, yet makes -200 pips a month, with an average expected return of 10 pips per trade
Trader B has 3% returns per month , yet makes 10,000 pips per month. with an average expected return of 100 pips per trade
Who is the better trader long term?
Well from the above stats we can figure out the following
Trader A, is either a scalper or a grid/martingale trader, who used increasing lot size to recover from a move against him ( that's why they have negative pip results) This kind of trader has a limited capacity issue, and historically will blow up at some point
Trader B, is a trend trader, using probably higher time frames, smaller lot sizes and is correct on market moves, as he is capturing positive market movements without having to escalate to martingale matters to capture positive results.
That is the key, you cant be lucky and consistantly bank 1000 pips a week... but you can be lucky and bank 20% return on a 5 pip move in your direction...
let me know if that makes more sense...
