Hello mico,

An EA should not be difficult for this system, BrunoFx is right we would need more information.
So far I understand all this:

- Use the 15 minute chart for the currency of your choice.
- Find the High and Low for the 8:30 - 9:00 (EST) time frame
- Then buy if price goes 4 pips above the high OR sell if price goes 4 pips below the low
- Do only one trade.
- Do not buy and sell ( either Buy or sell but not both).
- Buy or Sell whichever comes first.
- Do not trade if one of the bars in the specified time frame ( 8:30- 9:00) is over 50 pips.

So I pressume that you only buy or sell once a day, or you dont if it does not trigger the signal.
My question is:

- Manually adjusting the Stop Loss, Trailing stop and Profit limit.

This is the most important part, when opening an order (buying or selling), we need to set a Take profit at least or this cannot be backtested ?
I would suggest to indicate a rule for stop loss and take profit, then it can be done

Thanks
S.
