Ya, in my case I definitely had that feeling, like shoot, I missed the morning lets see if I can still make some trades
From roughly 30 minutes into trading to 3.5 hours into trading there will be an excellent move 90% of the time. That is when you make hay. If you miss that move you have to be very, very, very careful. Especially on light volume days when there is little pace. If you can’t resist, don’t turn your screen on. In the afternoon the ranges for the stocks and the market are set and you do not get big moves. Sure you can find a stock or two that are moving, but in general, most of the action has played out.
