FAQ
- Can I use both Betfair and PolyGram simultaneously?
- Absolutely — institutional and retail traders routinely operate across both venues. Betfair serves as the live-sports engine whilst PolyGram captures political and emerging-market opportunities. They function as complementary rather than competing systems.
- Are prices correlated between Betfair and PolyGram?
- On overlapping events (UK political contests, major sporting fixtures), price discovery tends to align across platforms. Temporary mispricings occasionally surface, enabling arbitrage-minded traders to exploit cross-venue spreads.
