Choosing a time frame to trade on depends a lot on your personality. An adrenaline hungry trader will likely seek shorter time frames and more action, while a calm-seeking trader will prefer longer time frames and sitting on a position for a longer period of time. What is your choice?
If you are not looking at all time frames then you are missing a lot. It’s kinda hard to put a jigsaw puzzle together if you never look at the picture on the front of the box.
