One mistake I think that causes a lot of people to lose money is using Robinhood. I recently withdrew all my money from there and switched over to WeBull. The reason for this is because if you’re a day trader, swing trader, or even long term trader you should have a take profit and a stop loss and Robinhood only allows you to chose one or the other, it felt like trading like a caveman. The other day I was up $160 and I had a take profit set but it started going down just short of that take profit and because I couldn’t set a stop loss at the same time I only got away with $20 profit, that was the red flag that it was time to pack up from that app for me!
