and vice versa when you do gamble and make some statistics then predict the outcome , it is like the way you do trading too .
It think it is not the same. Gambling especially dice, slots, roulette and other chance games solely rely on the internal setup of the game. So no matter how hard you prepare your statistics, it won't affect the outcome. Now with trading you have different factor to consider, it is not the outcome that you need to affect but rather your decision on which one to buy or sell. Meaning, in trading, knowing all the factors, news, development etc, can affect your decision and thus mitigate your risk factor.
that time trading just like gambling , it is uncertain and we are guessing based on something have no effect at all in the end.
