Add 'time to form bar check' to a Renko EA

I am playing with an idea that seems to be working but, like many ideas, struggles when the markets slow down. Since the system is working on renko charts I want to add a line to the ea that checks the time taken to form the last x bars. So, when a trade signal arrives, the ea needs to check did the last X bars form in a combined time of less than Y minutes.
I'm sure it shouldn't be difficult. Any tips please?

should be same as with candles
(Time[0]-Time[x])/60

No one to contribute? its pretty essential tool IMO.
