I was told that the cash-out feature in casinos is the same thing as stop lose in trading.
No, that’s not the same. In trading, you have what’s called a "stop loss" to minimize your losses automatically. But in sports betting, when you cash out, it can go both ways, either you’re cutting your losses early, or you’re locking in a guaranteed profit before the game ends.
People who don't trade might think that stop loss and cashout works the same way but there's a big distinction between them...in sports betting, the cashout offer is just simply based on what the bookmakers are making available to you, due to some factors in the match even before it starts your capital can be reduced and it all depends on how the odds are changing...in Trading just like you said stop losses minimizes the losses you incur.
