FAQ
- Can I use both Betfair and PolyGram simultaneously?
- Absolutely — institutional and retail traders routinely operate both. Betfair serves live-action sports; PolyGram handles longer-duration political and emerging-market positions. They function as complementary tools rather than substitutes.
- Are prices correlated between Betfair and PolyGram?
- For overlapping events (UK political contests, major sporting fixtures), quoted odds tend to align. Periodic mispricings between venues present arbitrage and statistical-edge opportunities for alert traders.
