Value betting software and web only provides bet slip for one bookie

Hi,

value betting only completes the bet slip for williamhill no other bookie so by the time i’ve found the bet the odds have changed and the value has gone

Is there a list of the bookies where auto bet slip is complete or is this just something which i have to live with?

Extremely difficult to secure the value for the odds being shown in either web version or software version

Thanks
P
