That is my modus operendi.
When VIX is below 22, and below 19, I am setting profit targets in the QQQ moves of .30 cents. When it gets to VIX 22 and over, I expect .50 cents to a $1.25. In either case, soon as the volatility in a move stops climbing, I´m exiting.
The other day it went down to VIX 14 and was seriously considering a trade for .14 cents. With 6 cents being for commissions. Hardly worth trading it. Still, to keep the hand in so to speak, would trade a minimum lot, or one contract. Can´t really increase the number of contracts until the VIX gets over 22.

I was re-learning how to DEBIT SPREAD from Ryan. Now I remember why I do not do them. ( I´m old and forgetful ) If you are accurate enough to forecast a POP with a 99% accuracy in anything, enough to cover the TRUE RANGE sufficient to collect a profit from a Vertical. Then I had long ago come to the conclusion you would be more profitable and better off, just trading straight by buying. So have sidelined the interesting DEBIT SPREAD idea again. With a moving volatility mental stop, tracking the change, you can exit and still show a profit of some sort, even if you just cover your commissions on a straight buy order. Whereas in a VERTICAL SPREAD you HAVE to cover more of a mini-trend in whatever you are trading, to break even, or take a loss, at least the commission loss.
My mantra is: do not take losses EVER, if it can be avoided. The profits, tiny, medium or large do not matter. Nor can I forecast the length of a trend. I´m trying to keep any loss small, hopefully just to commissions through TIMING. IF you time it right, you can. If you are wrong and the flutter in the market is a bit wider than you want, a reversal can cost you a loss, plus the loss of commissions. But nothing like getting eaten alive by small trends that abruptly stop when you are holding a VERTICAL.
