I have no problem hearing someone say they don't like my trade and give reasons as you did earlier. This is why I posted - wanted other viewpoints to consider.
Though I do keep tabs on the market all day, I don't watch the market constantly (I no longer day trade full time - not worth the roller coaster times I encounter sometimes).
The options expire tomorrow (Mar 11) at which time I planned on unloading trade, just felt this was a good risk/reward scenario to try and squeeze up to 675 points from a trade that looked like was almost a guaranteed 200 points.
As I said earlier, I felt jitters in morning when market failed to hit 13500 (on downside) and saw these option quotes and felt I could improve on my profit target.
I figured with one day to go I can take that chance when I have such great paramaters to fall back on to. If market goes up by 100 points tomorrow then same result from original profit expectation/want. According to certain stats I keep (small little strategy) when QQQ closes below Hi-Lo study (study of last 10 high moving average and 8 low moving average) I notice there is usually (over 80%) follow through the next day by 0.5% which is approx 70 Nasdaq points which will bring us back down to 13500 at some point tomorrow.
My 2 cents worth.
If I am not mistaken, the only way it works out better than simply taking profit is if it expires worthless right around the strike. So you want to be exposed for a full day for that, OK, up to you.
