*What else is required for such a person to control,is it still his or her emotions or what next?
*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?
I guess if you can control your emotions and keep yourself calm in any situation which is good, then it gives you a good effect to have a wise decision to have a good call in trading. Then if you still loss a lot in trading or investing despite the fact that you can control your emotions? Maybe you lack a good timing and knowledge, you're already composed so there's something ain't right when you are trading. I myself can say that I might can't control sometimes my emotions especially when trading, but can still keep up since I know what I'm doing.
Losses are really part of trading, but those losses have reasons behind them, one of which is that you haven't controlled your emotions, so you trigger the trade even if your confirmation is not yet confirmed, which is why controlling your emotions is best, like having patience and not hastily triggering the trade, as well as being greedy, which leads to losses and mostly chasing back your losses, which means you trade beyond your capacity. If you have already strategy in trading your mostly enemy is your emotions which really needs to practice to control also.
