I got an idea... what the point to put two pending orders and wait both them to be executed just to close them? Under this strategy we constantly lose one spread on opening second order which we don't need.

So, the strategy should be:
at 0 hour check MACD and remember two price levels according to your rules about for up and down trend.
If price goes down and hit bottom level - open buy with SL 50 and TP 30,
If price goes up and hit top level - open sell with SL 50 and TP 30.
If close order at 23.30 if it is still exist (not closed by SL or TP).

Following this rules we get the same result but lose only one spread.
I'll do this EA a bit later.
