I would assume the measurement would be against oneself. We are trading against ourselves, so others self confidence would not matter.
Cool mind is not the only thing that will bring you profits. There are a combination of things that will help you bring results. Knowledge of the financial markets is the foremost important aspect to be considered.
You must turn off emotions when you start trading, and clearly and focused on acting on your trading plan.
homeboy got me blocked but the gist of his opening was: wrbtrader said: Both Cognitive Confidence and Physical Confidence has been measured. Measurement is great stuff. Competence is a good too if a trader does not want to walk into a shitestorm repeatedly. Chick with the red drawers thinks she all dat with a bag o chips and disses the heck out of some dude in a lineup where the participants rank one another for IQ, then are ranked by an IQ test measurement. And her EQ is so advanced too. ...qued o'course, Annnnd the winner is... Hey Red: pot, meet kettle, LOL. Teamed with Cog Competence, Now you got something there. If a trader has demonstrated competence, and Still the confidence don't show up, well...
in cooling mind we the traders first of all have to choose the broker , because the broker can affects the result of our trading with certainly.
