I only needed a single symbol to test, I removed all the others.
I ran a backtest for 1 year and there were only 42 trades, this equates to 3.5 trades per month, in the past week there were no trades, the issue is that you have very few trades, this is not a bad thing, many trades do not mean more profit.
