You are correct. I have gauged a specific success ratio in my approach, and in order for that to materialize, I take position preferably every day. Whereas straight gappers--you, Robster, by the sound of it--may choose to sit certain days out--I elect to take a position even on unlikely fill days. Rationale is, except on rare cases, price will assume a pro-closure behavior, be it premarket or at open. My targets and stops are adjusted accordingly. Gappers I know would not bother with my two point profit, but chase, and have the resiliency to hang for five, six points and much more. My mental conditioning is not at that point.
That said, I would like to say I do not go blindly about my entries. Sentiment in the market, price action of several preceding sessions, and key news releases all serve as confirmation, and often as deterrents to my participation. Today was a key release, the December unemployment numbers, which gave us a gap where there was none. I timed the volumes, t&s, and some old fashioned gut feeling that this closure was plausible. In the end, I entered, fully accepting that a stop would have been hit. Once I 'write the check out' for my stop, I am free to watch the trade develop. Today, it came within a point of hitting my stop, but instead turned around and hit both my targets, and believe me, it was tough to wait and see.
I fully expect my plays, and parameters, to improve to a level befitting my eventual experience.
