Are you being serious? I placed the bet two hours before the tennis match was set to begin. It wasn’t until 15 minutes before the match was about to start did I notice that every book (including stake) now had a completely different price.
What were the odds like on other platforms at the time you placed the bet (2 hours before match start)? Did all of them have approximately the same odds as Stake or were there significant differences?
It’s a tennis match and it’s absolutely impossible that a line moves 800 cents the other way.
I am not familiar with the odds system that you are using. I am used to decimal odds, so I have no idea how big the change was. How would that look like in decimal odds?
