If the arrow points down, the previous buy order is closed and sell order is opened. If the arrow points up, the previous sell order is closed and buy order is opened. I am using the tester (visualization mode) to verify my code. It seems that no matter how I try, the EA does not close and open the positions when arrow indicator points up or down. The back test confirms that the EA is not working properly. Instead of opening and closing the orders at the arrow points shown by the indicator, the EA closes/opens order at some different time. I cannot understand why my code doesn't work.

In the beginning of start statement, I have the following code:

if (Time[0] == savedTime) {
return (0);
} else {
savedTime = Time [0];
}

This (I hope) will ensure that the code in the start statement is executed only when new bar has formed. Later in the body of the start subroutine, I query the indicator with iCustom function. The request looks as below:

iCustom (... 1)

The last argument of one specifies the previous formed bar, which is why it is not 0. Yet later I close the opened order with OrderClose and open new one with OrderSend. I suppose that both functions must be able to execute instantaneously.

The bottom line is: I am trying to create an EA based on arrow indicator. The indicator points either up or down. The way I see it (and I am probably incorrect), the only thing that I need to do is to close previous order and open new one when the next bar has formed. I would greatly appreciate any input into this problem.

Thanks to all.
