I like to use one really plain and objective trading system. I search for one that hit a CRSI below 30 and also has 4 closing prices decreasing in a row. Buy this close, estope 5% below the entry point and target 5% above the entry point. This strategy in a pretty good number of achieves 65-70% of win percentage. We do have a 1:1 risk; profit. this would be one trade following this strategy... target in 170,50.. stop in 154,20.
