Polykal watches both venues and judges each gap against what is normal for that point in the schedule. See the numbers.

Prices are the venues' listed YES prices at index time (~5 min cadence) and can be stale by the time you look; executable prices, fees and spreads differ. Impersonal analytics on public data — not investment or betting advice.
