If I were you, I will stop trading at least for a moment, refresh and cold my mind for a while, and let my regret and bad experiences aside.
And I will continue by analyzing and thinking why I was always lost and lost again so much in trading with the previous strategy. There must be something wrong.
I agree with your idea. Don't be too hurry to trade more if someone is not really confident. OP really experienced bad results in his trading, he must feel deep regret. In this situation, stop a moment to evaluate and calm his mind are the best options. OP needs to know what is wrong in his trading way, then he must fix it. If he doesn't evaluate it, he will experience the same situation as before. But to evaluate properly and carefully, OP needs to calm his mind first.
Once you do realize your mistakes then this is where learning would set in and on next time you would do trades then you are somewhat that confident since you had already able to experience it even though it wont really be making you a better trader on point but as you do engage on trades then you would gradually able to make some good decisions which might lead on
becoming a better trader as you do go ahead.Dont rush up on making profits because the market is always open on opportunity, it is really just matters on
how someone would able to sustain this one.
