What else is required for such a person to control,is it still his or her emotions or what next?
It's emotion that you have to control in trading and that is what I have seen to be fixed. It's very dangerous for a trader to let their emotions be on the top of their decisions. It can ruin your journey in trading as it will cause a lot of losses.
And what will be your advice to a person in that position or state and what kind of trader are you going to call such a person?
My only advice to a trader is never ever trade if your emotion is not stable. You should make sure that you're okay before you trade as it will help you to decide and execute effectively in trading.
