The solution to this problem is really easy and should be implemented.
If a line is +140 when you attempt to place the wager and it goes to +120 while attempting to place the bet, you should have a pop up asking if you accept the new odds. It shouldn’t automatically go through at +120.
The same can be said if you trying to bet a team -3 points and in trying to confirm the wager the line changes to -4.5 because a basket was made. A confirmation box asking if you accept the new odds should occur.
This should occur on any line change whether for or against you.
Then there’s the other option where you have a box check marked that states accept all changes automatically.
So for now we have what shows below. If you are typing in the bet and before submitting the line changes you see it, but as stated if it changes mid bet you’re stuck with it.
Note at the time, I was doing this the line was -8 -110 and changed to -8 -115 then to -7.5 -120
Add an option to accept new odds and another box that you can check mark before placing the wager to accept all changes. Either way the bettor makes the decision to accept the new odds or accept whatever the odds change to no matter what.
But in the end, it’s ultimately their decision and not a computer program forcing them to take the less desired odds if that is the outcome of the change.
