I have been a gamer since the early 90s, and a trader for over 10 years.
I see my trading like some kind of game. I like fast markets (NQ, FDAX...), fast and frequent entries and exits (scalping for a few seconds). To me, it is all about experience, skills and... FUN. The more you enjoy your "game", the more you play it. The more you play, the better you get at it. No rocket science.
I use game sounds (Super Mario coins, Turrican laser...) as trade confirmation, cancellation sounds in my trading platform, makes it feel even more like a game. A while ago I even connected a Xbox controller to my trading PC and tried the trading with the controller buttons, but it was too limited and slow, so I returned to the classic mouse and keyboard soon.
I often play games while trading, especially when the market is slow. Keeps me busy and prevents me from doing unnecessary trades.
