This was a good example of why you should sometimes wait for the opening range to establish itself completely (no entries before 9:45 unless a VERY STRONG TREND is in play since the premarket hours)
I did not do it this time, which was bad.
This video does show how it helps to have simultaneous charts open. You gain confluence, when your decided trend is confirmed across multiple timeframes.
Watch the video and hear me reason out loud.
