In my opinion, it depends on the merchant's point of view. If the trader is a scalper then
he follows the M1 or M5 chart and if the trader is day trading then he follows H1 or H4, if the trader
swing trading then he follows the M15 or M30 and D1 or M1 follow if the trader trading as a trading position.
So now you decide what type you are and follow each graph.
