Quote from matt122333:
What do you currently practice the most when trading options?
Abstinence
(And as a new options trader, you don't have any business selling puts. One of the few strategies that can really knock you out of the game. If you feel you must, then trade very small and fully calculate your risk. You've been collecting premium during a major bull market. But when the market changes...which it will...those positions can really bite you.)
