Simple Close Order EA

I need an EA that can close a single order if profit decreases to a specified percentage of maximum profit that reached by the order.

For example at a certain time after order placed, we reached 100 pips profit (maximum profit point in the order) and then profit starts to decrease. If we specify percentage %75, then when profit decreases to 75 pips order will close automaticly.

But if profit is very low (we specify the treshold in terms of pips on properties- i.e 3 pips) EA doesn't close order even if profit decrease. If profit increase and go beyond treshold EA actively monitor order and apply rules.

EA should work both sell and buy orders including pending orders. EA should consider spread and swap costs when calculating profit. Profit ratio (%75 in the example) should be changeable on properties.

EA will work only charts which we drag onto.

Source codes with comments is needed.
