I'll share the basic building blocks, but you should post your attempt (code) and then ask for help if you get stuck.

You're going to need two instances (handles) of iMA with the different moving average values you need: https://www.mql5.com/en/docs/indicators/ima

You're going to need to grab the datetime value of the 30th bar that your signal is valid for. You can ascertain this value by getting the current datetime value of the open candle (for the timeframe you're tracking) and then adding it to the value of PeriodSeconds() * 30: https://www.mql5.com/en/docs/common/periodseconds

For the above, I would consider storing the datetime value in a Global Variable so that you know which datetime value it is regardless if you close MT5 / change timeframes / recompile / etc: https://www.mql5.com/en/docs/globals

From there, you should have enough to implement your conditional logic to determine whether the signal is valid.
