So that I don't have to figure out the next time again when I need them.
The following must be true for profitable trades:
1 < (Avarage win * win frequency) / ( Avarage loss * loss fequency).
The above is kind of obvious.
Calculating losses in percentage:
Loss percentage all in all: 1 - ( 1 - percentag of loss per trade) ^ number of losses in a row
10 losses with 2% losses per trade result in 18.3$ loss on the account
10 losses with 3% loss per trade result in 26.3% loss on the accoutn.
Now it is possible to calculate overal account risk percentage but I hate to get that mathematical about this.
