In trading the results will be not same such as yesterday and possible too for that day you will experience to loss because you had wrong predict for the prices movement however even these jobs full of risk but some people very enjoy for trading and they more likely to choose trading than other jobs
there is no doubt abuot this that every kind of trading is risky, and some time your prediction can prove as false and you can face a big lost, but i think there are so many experience people who are really giving too much good prediction about trading and mostly their prediction proves as right and so they get so much benefit from it.
