I did get it to work but I had to play with the RSI values. This strategy only triggers on the cross over event but at this point your RSI is already above or below the values you are using. I changed the RSI values and I did get it to trigger.
You could either modify the RSI values or try various EMA values since RSI will ride up or down as price moves. So the more price moves before the ema "cross", then usually the more RSI is going to increase or decrease (above or below your values).
