How to achieve "wait" in seconds?

[Zackry]

let say the ea buys when EMA 5 crosses above EMA 20, but now i want the ea to wait for 30 seconds before opening the trade.
meaning EMA crosses above EMA 30, wait for 30 seconds and then open the trade

The key factor is the moment you want to be considered as crossing happened. I mean, are you looking for candle ID 1 or 0 to be checked? I guess it is ID 0, but then consider all issues related to it.

@l-andorrà candle 0 , this is what i am trying , fast ema crosses above slow ema , then wait 30 seconds and , if the ema fast is still above the ema slow then enter buy
