Correct, trading is just like gambling. It is very risky but if you know how to manage your risk it is also profitable tough.
You just contradicted your first statement. If trading was similar to gambling then there would be no method to make it into a profitable earning method. But it can be done so. Gambling is always going to be a loss for the player because they are fighting against the odds. Trading if done on the right assets and at proper times can end up being profitable.
Trust me, if we went around the forum all day picking out comments that contradict each other or even don't make sense, we'd never finish our jobs. Guys like them obviously either never really traded or never really gambled. They just talk out of their arses thinking they make sense but never did anything close to trading or gambling to make sense.
