I do not understand about trading but in my opinion is very different from gambling. because basically gambling is risky and can not use any tricks. different from a trading using calculations subuah
If you are just differentiating trading and gambling with risk maybe you can check it again because they are both risky. But they are totally different on how it goes gambling is a fast game of money where the chances of losing is fast too but in trading you need to use your skills and knowledge upon on how market moves.
but i think if we compare the risk factor of both trading and gambling. i think gambling is more risky than trading. in gambling for some games we totally depend on luck while in some gambling format we depend mostly on our luck. while in trading although luck is also involve there but still our experience and our skill can change the result of the game.
