Build EA From Custom MT4 .ex4 Arrow Indicator I Provide

I would like the EA to open a position in the direction the indicator gives, every time it gives a signal, at the close of that bar. I would like to be able to set the day and time, to the second, as to when the EA activates and will start opening positions. I do not want the EA to open a position immediately when activated, meaning it should not open a trade based on the last signal that has already past, so it waits for the next signal to open it's first position. There are a few more select-able parameters required as follows - Lot size - Stop Loss - Break Even - Take Profit - Trailing Stop - Max Slippage allowed
