But it cleared up almost immediately when I began to view the day as divided into three separate and distinct trading sessions: the 1st Frame, the Midday Frame, and the 3rd or Last Hour Time Frame.
These are just names. In truth, the periods don't last for exactly the same time each day. The 1st Frame of the day can last about 1 hour and 45 minutes, give or take about 20 minutes.
