I got this simple system from the book High Propability Trading Set Ups and it seems really profitable, so I want to implement it as as EA.

Here are the rules:

Rules for a Long Trade
1) Look for currency pair to be trading below the 20-period EMA and MACD to be negative
2) Wait for price to cross above the 20-period EMA, make sure that MACD is either in the process of crossing from negative to positive or have crossed into positive territory no longer than 5 bars ago
3) Go long 10 pips above the 20-period EMA
4) For aggressive trade, place stop at swing low on 5 minute chart. For conservative trade, place stop 20 pips below 20-period EMA
5) Sell half of position at entry plus amount risked, move stop on second half to breakeven
6) Trail stop by higher of breakeven or 20-period EMA minus 15 pips


Short Trade
1) Look for currency pair to be trading above the 20-period EMA and MACD to be positive
2) Wait for price to cross below the 20-period EMA, make sure that MACD is either in the process of crossing from positive to negative or have crossed into negative territory no longer than 5 bars ago
3) Go short 10 pips below the 20-period EMA
4) For aggressive trade, place stop at swing high on 5 minute chart. For conservative trade, place stop 20 pips above 20-period EMA
5) Buy back half of position at entry minus amount risked, move stop on second half to breakeven
6) Trail stop by lower of breakeven or 20-period EMA plus 15 pips



It may looks to easy, but I believe its worth to make an EA and see how it works in forward testing.
