Hi Mariano. Some additional questions so I can help better;
1- What is your trading experience?
2 – What kind of account are you trading this on (demo, live, broker etc)
3 – Have you compared any real time tradng results with the backtest.
I would always recommend trading with the lowest risk, and 1 or two weeks in trading is totally meaningless in my opinion as all strategies have drawdowns and stagnations much longer than this and that is normal
