The last four weeks have been the biggest one month rally in 15 years. You can't expect every day to be like yesterday was. Yesterday was nuts actually.
And the first hour and a half can be a very difficult time to find a play on any day. Like yesterday, 11:00am was the time to start betting on things to go down, after they had gone up too far too fast. But until it reached that point, it would be hard to know when to bet on it.
Some days you just can't quite tell what to do, and it can be better just to stay out of the game on those days.
You learn as you go. I have a long way to go myself.
