After closing yesterday near the previous record highs, markets may pullback a bit but no way of telling for certain. Best to wait a bit and see.
VERY important to have a pre market routine if you are day trading which includes but is not limited to:
Scanning for high quality gaps
Going through trading plan and affirmation
Taking a breather a few minutes before market opens and when it does open to get your mind right
Having a routine and a plan helps to ensure better success for you, as it helps take your emotion out of trading, which is one of the best ways to make money.
