How to make a code that uses 1-hour time frame to start at the bottom of the hour?

I wrote a simple code for my watchlist to let me know if the current hour candle is green(Up), red(Down), or white(Neither), for only market hours (no pre/post market data). I’ve hid the “Extended-Hours Trading Session” on my hourly charts so the candle will start at the bottom of the hour, i.e. 9:30am, instead of 9:00am (which happens when premarket data is shown).

Here’s my code:

plot dir = if close > open then 1 else if open == close then 0 else -1;

AddLabel(yes, if dir == 1 then “G” else if dir == 0 then “U” else “R”, if dir == 1 then Color.black else Color.white);

AssignBackgroundColor(if dir == 1 then Color.green else if dir == 0 then Color.white else color.red);

I made sure that the “Include Extended-Hours Trading Session” checkbox was unchecked. Whenever I look at my watchlist, the color inconsistently matches the hourly bar. When I allow my hourly charts to show premarket data, the codes matches it perfectly, but that’s not what I want. I need this code to match the candles that are at the bottom f the hour, not the top.

Thank you in advance for your assistance.
