Combing in MACD and MTF

Hi all, I'm trying to wedge in the MACD into a multiple timeframe. Scope is to create:
1) an alert when the MACD across all timeframes is positive,
2) an alert when the MACD across all timeframes is negative, and
3) one when neither of them is applicable.

Would anyone be so kind to give it some thoughts, please?

Guys, I need some help, please.

1) why doesn't my script close a position when TF_global_off kicks in? and
2) why there is a gap of time between the fulfilment of a condition (all green or all red) and the actual opening?

thanks in advance

this should be the final version. Exit points correctly visualised and good results.
only regret I have is that I would prefer to be able to count data from the open of the candle, instead of the close.
