I don't know if such feature is available on any casino, haven't seen such anywhere, and I am eager to know what you guys think about such a feature, and feel free to use this thread to suggest other features you did like to see in our online casinos.
Basically, you want an automatic cash-out if your parley reaches x2,x3...x10 at some moment. I have never seen anything like it, and I doubt this will ever be available. The question is how many people would use it, and whether it would be a popular option for punters. If it is not something that can attract a large number of people, I doubt that the casino will bother to create it.
You only have one thing left, and that is to follow your games and cash out manually at the moment you want.
Well, I am not here to answer for the op, but on my own personal assumption, I think a lot of punters will make use of such feature if implemented by any casino, you can never imagine correctly how much alot of punters lose to sports betting simply because they were too busy with something more important, and couldn't stay online to monitor their bet and cash it out when the opportunity presented itself.
With a feature like auto cashout, punters who know they are too busy to monitor their bets will simply set the auto cashout to trigger any time a cashout offer of x3, or x5, or even x10, x20 or more is available, depending on the bet ticket, if it's a parley with big odds.
It's a nice feature, and the only reason why casinos would not want to implement this is not because punters won't use it, no, but more of because it will help punters win more than they usually win in sports betting before.
Well, definitely, the implementation of this function will lead to a global decrease in casino income.
Therefore, there is great doubt that any casino will be so concerned with the need to perform such a, one might say, charitable, social function as this proposal, that it will take it into work and implement it in its casino. This does not look like the real state of affairs in such a super-competitive business environment as the gambling industry.
After all, the care of the clients' money and its movement lies entirely with the clients themselves, even if they are completely stupid, forgetful, dumb or even dumber and generally almost crazy.
