How many hours would you say that or an effective course of action would require from a trader just walking in the options door that day trades well of off stock and etf PA action that has a successful track record when applied to the stock's 5minute charts themselves and the day-trader's new intent is to work the setup triggers using weekly options to be held for a range between 20minute to 60 to maybe the rare 240minute hold time? For that scenario and considering the amount of Gamma effect to be found on a max 240minute hold, how much time would be required to take Gamma into relevant consideration, Two hours, Tens, Hundreds, Thousands of hours?
How much gamma rate of change for a ~40delta based on a 3% move in a leveraged etf's underlying's price for a 60 minute hold on say a Thursday could there be? How much associated % reduction in that trade's net could there be?
How about a Friday afternoon?
I'm thinkin' it has relatively little effect on the profitability of the trade.
If that's true, then why would more than a passing familiarity with the definition of Gamma require more than an hour?
