Arbusers

Hey everybody,

I'm a new arber who's just starting to play with this interesting world.
From what I was able to understand so far a huge part of being in arber is avoiding and dealing with cancelation or betting limits.
I was wondering if people with experience such as yours could help and educate me in what are good ways to avoid the cancelation of the bookies, and if this already happen, how can I go around it?

Thank you very much!
