Cash out in gambling will prevent you from the lose. That will similar with stop loss in trading. If you can use both in trading and gambling, you will prevent the loss. But badly, most people are tempting to become greedy in gambling and trading so they are not use that feature because they expecting a big profit.
I do both gambling and trading and I can clearly tell you that the "stop lose" In trading is not same thing with "cash out" In sports betting. Stop lose is very good because it has precision but cash out don't have. You can set your precision in trading and once price hit there, you are off from the trade, but in betting you can not do the same. If you are not watching the game to know when to take the cash out, you will miss that opportunity. Cashout offers are not stable, it can appear for some minutes and the next minutes you won't see it again.
It is precisely because they do not have an exact stop in the game that many players do not feel the support under their feet and continue to play in situations where they should not. This is more about self-discipline, which players often do not want to pay attention to, because many do not want to take the game too seriously, because many of them even take it frivolously, sometimes win and are proud of it. This can also interfere and affect the player, especially when he loses and begins to prove in the game that he is not a loser with his money.
It's lack of self control or discipline that can make the gambler to gamble in a situation they are not supposed to, if they think it's same thing with trading, they didn't realize that they can have more control over their losses in trading than they can do in gambling. Some people do not even have any experience at all in trading but they just blindly argue that both are same thing when there's a big difference from the both activity.
