Quote from NoDoji:
He didn't buy calls, he bought DITM puts (making him short).
He said he had a plan at first to wait for price to rally to a certain level before beginning his position. The problem is that he jumped the gun because the price run up didn't occur in his time frame. By waiting until price reached the level he planned for, the end result would have been a scratch or a small profit.
And a couple days before expiration you need to be right on direction, there's no room for averaging down, IMHO, even if the strike is DITM. FNSR wasn't far from becoming OTM on the run up.
