Exit long position when hourly candle stick touches EMA(133)

Enter short position when hourly candle stick closese below EMA (13)

And exit short postion whne Hourly candle stick closese > EMA(9)

Many thanks in advance.

Buy : -   CROSSOVER(CLOSE, EMA(CLOSE, 33))

Exit Long  : -  CROSSOVER(EMA(CLOSE, 133), CLOSE)

Short  : -  CROSSOVER(EMA(CLOSE, 13), CLOSE)

Exit Short  : -  CROSSOVER(CLOSE, EMA(CLOSE, 9))

We can't define Time Frame in Trade script. We have to select Manually while back testing.
