I was recently told about a strategy that has a 90% success rate and I'd like to see if someone could code an EA for it.

Here are the rules...

1) This only works on the GBP/USD & only on the 15 minute charts.
2) Take the High & Low of these 3 candles - 08:15, 08:30, 08:45 (EST-NY time)
3) Buy when the price reaches 1 pip above the High
4) Sell when the price reaches 1 pip below the Low
5) Initial trailing stop of 15
6) When the price reaches 15 pips profit, change trailing stop to 5

If anyone can do this that would be fantastic!

Thanks a million!

I don't know who told you about the 90% success rate. When I back tested this strategy during the last 2 weeks it came out to a loss
I have played around with various session overlapping brakeouts and I see that it has potential for automated money making... I'll try to modify your approach during the weekend using historical data and I'll see if this gives any profit.
