Approach to consider various confirmations happen across ticks in an EA

Hi, I would like to check for multiple confirmations such as fast EMA cross slow EMA, MACD crossover, etc to determine sending order or not, but these events may not all happen on the same tick. I want to consider them as long as they all happen within a reasonable time period. With EA logic being executed every tick, what should be the approach to implement that?

Thanks!

Mike
