Professional traders have losses as well. It’s all about the size loss you take (relative to your account size) and how you recover from a losing day. I have some great tips on how to recover from a losing day.
Losses are inevitable but do not let it discourage you
If you have a small loss one day, review your trade. Determine if your entry and exit was according to your trading plan.
Did you take a bigger loss than you intended? “Hoping” That you can recover some or even tried to break even. If so, take a few days off in order to put your mind at ease. Once you are mentally ready to focus again, reduce your size position going forward until you build back up that confidence.
Always trade according to your trading plan, if you are still in a trade and it’s against your plan. Get out.
