You really want to know how to make stupid trading mistakes by fear? Or is it the other way round?

If its the other way round, then one way is to slow down, you are too fast in making your buy and sell decisions, just like you were to fast and anxious to post this that you didn't even read what you post.

But on the other hand, if what you want to know is as you have written it, then your answer is to continue to allow fear to make you stupid, then you will continue to make stupid trading mistakes as you've asked.. That all.
