Being overconfident is very bad. Initially I was overconfident but now I am not over confident. But there was time when I used to get over confident at my earlier life trading. Whenever I won 2 or 3 consecutive trades, I became overconfident. As a result I used to open more low probability trade and incured loss. But at present I am not like that. Now I only open trade if it meets my checklists criterion. If I do not get any set up, I do not open any trade. I also use a good broker which is AAFX. It provides a wide range of services to its customers.
