is there an indicator available where I can highlight bars at a certain time?
I looked for it but didnt find anything. what I mean is the following.

I just want to have two dots (one above/one below a candlestick on a 5min timeframe or 1hr)

purpose of this is: I want to track the opening bar (does price trade above or below) and then I want to have other times e.g. 8am opening (5min bar)
11am (lunch break) 2pm US session start and so on. all on 5min bars.

thanks for any help
