Trading is a very difficult thing, especially when classic technical analysis not works as far as fundamental one. Only whales know when the price move on.
Like few years always the market had bull run and in that period the traders did make money and cover up their losses which is not the case till now as market has not had the bull run like previous years due to which traders did not got the chance to make some great amount of money in their trading and this is what it is frustrating everyone.
Bull markets can be very deceiving, if you invest when the market is about to skyrocket you may think that you are a genius and that is because you do not have to do anything to earn a huge amount of money, and the worst part is that you may believe it and think that you are some kind of genius when you are not and then when the market goes down you believe that you can still make money in it only to lose everything.
