3 EMA Indicators

Hi,

I need an indicator that will automatic trade for me at the close of the current candle if the wick has touched a certain EMA while three EMA's are lined up in a trend.

Condition of buy signal :

1. EMA 10 cross over EMA 20

2. Last candle is over EMA 50

3. Price closed at 10 candle back must higher at least 12% of current candle

Sell signal :

1. EMA 20 cross EMA 10

2. Last candle is under EMA 50

3. Price closed at 10 candle back must lower at least 12% of current candle

Indicator should have the ability to change the EMA Periods and the MA types (EMA, SMA, SMMA, LWMA)

Signal arrows must be shown

Please feel free to ask me for any other information
