If Scotia 85 did not take our knees out over a mere few seconds this week with a bulk order, PTK's SP is probably at 2.50++ right now.
Wheather it was HFT or a nasty market order, either way it was an unfortunate trade that likely triggered a few other trades/stop losses....remove that, the week was not as bad as it looked.
It is of no matter. Eye on the prize. Day to day SP is less important than the end game.
