5. Stay calm and try to control temporary emotions.
I think the most crucial thing for a trader is to truly understand what you're doing. When you have a solid grasp of your strategy, your emotions are less likely to take the wheel. You're confident that your approach will lead to profits, which lets you stay calm while you work. Trading is a mental game, and once emotions get involved, they can cloud your judgment, leading to regrets later on.
Exactly, Understanding what you are doing is basically the key to emotional dealing, this brings my memory back to when I was a newbie trader, I was trading with emotions because I had no proper knowledge about trading, exited trades when the market was on correction, and the worst of it was that I was using high leverage and a little bit more above my entry point I'm already on huge lose.
To manage emotion don't trade with money you can't afford to lose.
Stop using high leverage or lot size and manage risk.
