Quote from The Swordsman:
Yes, if you are trying to catch high momentum situations, you shouldn't find yourself out of the money if you know what you are doing. There are times during the day that, if you watch closely, you know if so and so price is touched, we should get a strong move off of that price immediately (or shortly thereafter). Now, the length (ticks) of the move and how long it lasts (time) are variable so its very important to watch for feedback confirming the momentum.
alot of it for me is feel after i enter on these trades, once you've seen them enough you get a sense of which ones are good and which ones are marginal.
