So why we still think that trader is a profession? It is the same with gambling. He tries to predict result and get some profit with it. Of course, i`m talking about sport betting, it is predictable and we can calculate something. Not 100% of course, but it can be enough to get profit. Random games is only expense, even if we sometimes win.
I disagree. In trading there somehow a safety pin to avoid losing it all. The market moves but it doesn't go all the way down to zero in an instant. A trader could still save his money if he knows what he is doing. Alarms and notifications will really help in this situation.
Gamblers on the other hand doesn't have this kind of features to help them save their money. The cashout button doesn't work when the team you are betting for is losing. It only works when you hit your bet and want to pull out early to avoid losing it in case the results changes while there is still time left
So I think there's a big difference.
You can cash out, when you see that something goes wrong. Of course not every moment, and not when it is too late, but often you have such opportunity. Also, you can try to hedge your bet. I can`t say right now how to use it like traders use stop-loss, but i think that it is possible to calculate how to get something like it.
Anyway it is tool and tools differs because it is different "markets" with different rules.
