You get a feel for it as you do it. There are still many variables, like the overall market. Works well in a bull market, but if you get caught holding and dividend stock, then you are still earning. Also your boosting your income by writing covered calls. I have some stocks I have been in and out 10 plus times a year. Some I keep writing calls and keep pocketing dividends. I have a goal of $500 a week and I have achieved that the last 2 years and exceeded it. This year my average is $1200 a week. I am playing with a decent amount of capital and retired, so its more of a hobby.
Don't get greedy. I will take $100 from a trade in 1 day and be happy. Better than gambling and better than getting .01% on MM.
But don't get me wrong, last March/April, I was holding and sitting on covered calls. I made money on every call but was sitting on large losses, market came back and I wrote covered calls all the way back and called out on most of them.
Cash secured puts, you need to have the cash in account. I calculate my yield on the cash. So if I secure a put with say $10K and it makes $100 in say 1 month or less, that is a 12% plus annual yield and I happy with that!
