I can totally relate. Making nice profits when the market is stable, losing a week's worth of profits in a couple of bad days like earlier this week.

Educating yourself is super important. Stay away from YouTube channels promising easy profits.

Decide how active you want to be, day trading, swing trading or longer term investing and find books with tons of good reviews.

Over the last 3 years I've tried a little of everything, day trading and swing trading stocks, buying call and put options, futures, you name it.

My best advice:

1. In real estate they talk about location, location, location. In trading it is money management, money management, money management. To give yourself the best chance to be around for the long haul, keep your risk on each trade small.
2. Your highest odds are in selling options. You limit your upside on each trade, but you have better odds. If it goes wrong though, it can be catastrophic, so you have to be super disciplined respecting your stop losses.
3. Look into the wheel strategy. The account where I do that almost exclusively, is by far my most stable account.
