Maybe I am comparing apple to orange, day trading vs longer time frame option trading.You have it backwards...It is easier to figure out how to trade outright with margin in your face than with optionality to mitigate the outrights on day trading with all that IV stuffs.
Options are quantifiable, are probability & algorithm based, almost everyone follows some basic algorithm & logic to price them. Once you understand the math and logic, there are many potential paths to profit.
I can't find any logic and algorithm for day trading, price change is almost Markov. My hat off to those who are consistently profitable, year after year, they are a special breed.
