Well, I first went short at 3658, 3662 and 3880, it popped to 3684, pretty scary trades, and finally bailed out at average 3667 with a small gain.
Could have gone long or short either way to make money but I rarely trade actively in the afternoon because my margin wasn't big enough.
Well yeah in the morning short worked good and long worked out even better but after 11:30am it was virtually straight down the rest of the day (relatively speaking on a larger chart). It eventually gave clues that it was likely to be a long squeeze, so I prefer to trade in the most likely macro direction for the day. Although clearly you don't have to and sometimes it's just not possible because you get it wrong.
