$DEXE feels so painful, it turns out that to think big you have to make fewer short-term trades. When 17 ran away, I thought it would drop and I could buy in again, but then it surged ahead, increasing more and more. When it was at 19u, I was unwilling and wanted to short it, trying to recover what I missed. After thinking for a while, I decided to stay calm and took a nap. When I woke up, it really took off. Luckily, I took a nap to calm down, otherwise it wouldn't have just been a matter of earning less, but I would have been beaten by the market so badly that I wouldn't recognize myself.
