People should be able to set their own goal, and work towards that and not get greedy and just keep at it as long as they possibly could. That would make them lose as much money as they normally would and it would be a smart decision if they end up holding it out until their strategy works.
Easier said than done. Many follow the best strategy but end up losing. And why is that? Because they can't follow the strategy till the end. This all happens because they are unable to control their emotions. People tend to look past emotion control while learning to trade. But to me, it comes first. Telling from experience, I have followed many strategies, and I have made some good profits too. But I have lost more than what I've made. Everything was right, the calculations were right, and the price was moving in the predicted way. But the sudden price drop/up was putting me in red. I closed many trades that way.
In the end, the problem I found was that I was not able to control my emotions. Because after many trades I have closed, the final results were the same as it was predicted most of the time. So then I have fixed my mistakes and learned from them, and now you can say that I am doing a good job in trading. Not the best but not as before only making losses. So yeah, emotion control comes first. I made decisions where there was no need to. And that I have learned in a hard way, LOL.
