Being angry would be just normal because we dont want to lose money and with this very unpredictable market then situations like this is really unavoidable due to unpredictablity
and you should be aware on the first place so that you wouldnt really get shocked once you chad seen your portfolio drop that fast in a short span of time.
Its normal for a human being to have these reactions but you shouldnt really tolerate this because once you get angry will really result into desperation which would
create bad possible moves.
Is it normal to get angry when something does not go your way? Yes, is it productive and it helps to resolve your problems? No, when it comes to trading you need to try to remain as calm as possible even when the market turns against your prediction, and if you cannot do that then most likely you do not have what it is necessary to become a good trader.
Also sometimes the anger comes from the false expectations traders have out of the market or their own skills, no one wins 100% of the time or even something close to it, if your prediction failed then just accept it and move on, because if you do not then those feelings could be the reason of a subsequent error.
Anger would really make the situation even more worst if you do let your emotion do control you because if you are in the state of anger then making out decisions will really be not that well and making out mistakes just because you cant think that well.
Things wont go as we anticipated and if it does then lots had already been smiling on making out of this market. This place is never been predictable so its just normal that you would really experience these situations.
Just get used to it when it comes to situations like this because lots of possible situations that you would surely be facing off and this isnt the only
one will really make you angry.
