Hi, I am new to options and am still learning how they work.
Currently my hypothesis is if I am selling (getting credit) using vertical spreads and iron condors on 0DTE options, I should primarily be concerned about **NOT** going in-the-money. And for that I should be selecting the legs based on (technical) analysis of the underlying.
Can someone please help me in understanding why are Greeks important is this setup and what am I missing? All I want to make sure is that the price of underlying stock not touches my leg, and I don't do ITM - and retain the premium I earned. Now Greeks will determine how much is the premium on that leg, but not if I am positive or negative. Am I correct? TIA
