Yes, the big bookies will definitely know when their book is 'overbroke' I.e. There is no profit margin in their odds at over 100%. They will have an algorithm to pick out those out of line odds, and traders overseeing the odds.Yeah could be that, they were both around 99% will try one at lower cheers
Edit: Hmm dunno... tried one at only 97% and still it would only allow £5... not going to try any lower and lose too much in QL... Bit of a newbie question (from an oldie) do bookies know when their odds are higher than in Smarkets etc? like when over 100%??
At Coral, for example, you will have a customer profile with a stake factor on certain odds, which may differ on sports depending on what odds you've taken so far.
