Upgrade with RSI and Stochastic

I have an EA which needs an upgrade.

First of all it needs a double check to see if position is correct (long or short). This should be very simple and special condition will be explained.

The EA has two moving averages and I want to add RSI (and maybe Stochastic), to the existing strategy.

I also want the option to choose between trade on 1,2,3 or more signals and as the last thing I would like to have Trailingstop.
