I have noticed also that this fear can help you reduce lose sometimes when you fear to pull in your trade then you stay back and at the end the market would have gone against you. It means that the fear actually was to your advantage because you didn't enter an order.
Well sometimes if you rely on that youd lose some chance to gain too. It happened with me all the time, that I fear to enter this particular trade and suddenly it goes beyond what I am expecting too then I regret for not having enough courage. But it also happened that I bravely ape some coins and If only I got fear to not do it I could save my capital. I think its a loop for both pros and cons.
Sure it is both pros and cons. Sometimes you are in at the right time and sometimes too you are out at the wrong time vice versa but I have taken a decision not to regret whichever one I follow but what is important is not losing your capital unnecessarily.
They say not trading or being outside and waiting is trading itself because you might be saving yourself some loses while staying outside.
