Priorbook · Arbitrage
This isn’t Priorbook’s main focus — arbitrage scanners are a commodity, and that edge is shrinking fast as more of them compete for the same spread. But it’s still useful, so it’s here. This is a basic, static scan of the highest-volume contract per curated topic on each venue — it does not verify the two questions are identical, so read both before treating a gap as a real trade. Pairs with an implausibly wide gap (almost always a sign the two questions aren’t really the same bet) are left out rather than shown as if legitimate. A live, continuously-refreshing version is planned.
