I still don't understand the sense of asking that question.
Each trader has a different way of trading:
So what is interesting about knowing % of commission without knowing what kind of trader the person is? I really don't get it.
- some trade frequent with small average profits, which causes a high % of commission on profits.
- some trade not frequent with bigger average profits, which causes a low % of commission on profits.
The only relevant information would be to know the commission structure per trade.
Simplified example:
Trader A pays 2 pips and has an average profit per trade of 5 pips.
Trader B pays 20 pips and has an average profit per trade of 150 pips.
Trader A pays 2/5= 40% commission
Trader B pays 20/150=13.33% commission
But the broker of B is 10 times more expensive.
Hint, I am only interested in the trader that survived very well.
