ThinkOrSwim Candle Open/Close Setting

Hi Fellow Traders,

hoping someone can help because im racking my brain trying to figure this out.

I have read the best time frame for candles to open and close on are the New York GMT -5 time zone.

My questions is how do i set this in TOS?

ive found how to change the timezone under style >settings > general, but this doesnt seem to change the chart candles open and close.

Anyone have any ideas?
