I have not had good trades with "overcome fee costs" but rather with "Procent price change -Insurance (Wanted raise: 1,0 %, Wanted drop: 1,0 %)" Two trades at 0.2% each is 0.4% so a 1% change should cover that. I know that is not exactly an exact calculation but so far it is working.
I've added a RSI Indicator with no ensurance. It makes some trades where i lost a bit, but on the oter side i win even more.
