阿尔诺方法 (Method Arnau)

I started using the fozzy method but it did not convince me.
I started to use Rsi(14), EMA (8) and the bollinger bands based on the EMA, not in the rsi as the fozzy metod.
I applied to this chard the following rules:
1- When the EMA cross the lower boll is a BUY (EMA1)
2- When the EMA cross the upper boll is a SEll (EMA2)
but sometimes the prices don't take the correct way as I would like, then there are two important rules.
3- when the current EMA goes lower than the EMA1, it produces a close position of the BUY and after that a SELL
4-when the current EMA goes upper than the EMA2, it produces a close position of the SELL and after that a BUY

I attached a chart for better understanding

I have good results graficaly but i tried to proram with the mt4 and it does not the results as i expect, sometime it doesnot do what i want
Can some one help me?
