Well, my platform does a neat trick, if I don't make 4 points in 30 minutes, it shuts itself off when all trades completed, I was up 3 ticks in 30 minutes day session on closed profits, had couple open trades which eventually made 4 points, but closed down at 9:06 so off to Starbucks early. You do enough back tests to find optimum trading times and don't want to be giving it back. Trade well all FOMC coming up in few hours, fun to watch only for most.
I use to be always afraid of reports till you figure them out, first moves generally wrong and they are to be faded.
