That chronology of trades and posts implied he was long into the open, taking heat BUT adding to the original position as it declined. By the time he got that second add at 7484.50 x 20, he was down $27000+ on the first 20 lot. Nowhere in the language heading into the "adding here" do we hear about a stop out on the first 20 lot.
When he says he lost $9600, then went long again, NQ was down at 7414.00, there is no possible way to make the math work that he took only a $9600 loss, best case would be a -$15100 loss if he added another 20 lot, then sold at the top tick on that swing before it plunged again.
