I would like to confirm when a daily bar changes it's index from 0 to 1, e.g. close[0] to close[1].
I am developing a strategy that runs on a 1 min time frame of Index Futures and 1 minute before the session open, it requires the prior day close of the cash instrument (an added series). My testing suggests that the prior day cash close is as follows:
Before the cash session open, Closes[1][0] is the prior day cash close
Immediately after the cash session open, Closes[1][1] is the prior day close.
Is my understanding correct?
Cheers
Tony
