actually no and Fairlay can't be compared to Orbit IMO , they are different anyways
Fairlay still can't be compared to any exchange , cause the majority of times it only has pinnacle prices so you can't really trade since the odds are directly from a book and the spread is relatively high unlike orbit where the odds are different and the spread is lower  ( difference between back and lay is usually one cent in orbit , you won't find that in fairlay )

the only reason I mentioned fairlay is because he wants to use pinnacle and fairlay can solve that , but it can't really replace betfair unless more traders started using it and creating real orders that aren't directly from pinnacle
