Simple EMA crossing robot with close order strategie.

I want to try a simple EMA crossing Robot. Tile Frame : the current Time Frame. Need 2 EMA :Fast EMA and Slow EMA (Need to be possible to change the 2 EMA period) - Buy signal : when Fast EMA cross up SlowEMA while the 2 EMA are going UP.  - Sell Signal :  sell when Fast EMA Crosses down the slow EMA while both EMAs going down - close Buy position signal :  close when Fast EMA Crosses down the slow EMA - Close Sell Position Signal : close when Fast EMA Crosses up the slow EMA.   I would like another option : A configurable trailing stop loss. (I insist on TRAILING) And the possibility to choose if I want to close the positions with the trailing stop loss or with the closing signal.  That's all I need.
