This. If you trade small you've gotta take small profits and compound. Very, very few people have the discipline to do this
Trading small is good to get your confidence up. I was dealing with bear market PTSD so taking a 5-10% loss was messing with me heavy. Another mistake I was making was setting my stop losses too tight. Wake up thinking I was up 25% when I took a 5% loss getting wicked out over night. Had to learn patience and take my emotions out of it. Before I used to revenge trade but I didn't fall into that trap.
After a few successful trades I was happy with how I did.
