Multi-MA Expert Advisor

I am looking for a customised EA which opens positions based on the price/candle bar closing above (long)/below (short) of the 3 (variable) moving averages for the EA [so position opens when candle bar closes above/below the 3 variable MA's].

 I would like to add a SL and TP variable as well - timeframe will be whatever chart is open and activates the auto trading.

 The EA should also close the position if the trend has reversed and open in the new trend.
