I want to play with SPY 0dte or 1dte. I want to buy a contract and want to consistently get 0.1 increase in premium. For example, if I buy an atm contract which has around 0.4 delta, for the option premium to increase by 0.1, I want the price to quickly move around 25 cents in my anticipated direction.
\* How realistic is this?
\* If this is realistic, how to identify the entry opportunities?
