If you’re a day trader there are certain times in the day that give you the highest probabality trade as demonstrated with the two charts below. The first is 30 after the market opens, if there is a reversal in trend it will most likely happen here.

The second is at 12pm EST, this is when traders go to lunch in NY so the market will slow down, trade sideways or trend down. The 3rd reversal point is at 1:30pm and you can see from the charts below they turn exactly at this time. These patterns are not written in stone but they happen very often.
