every arb, in the open.
Public log of every cross-exchange arb the Tellmarket scanner has surfaced — dates, edges, durations open. Filtered only by the same data-truth gates the live feed uses (edge ≤ 15%, from a currently-active matched pair). Grouped by market so a single arb that flickered open→closed→reopened shows as one row with a capture count.
Cross-exchange arbs above ~1% net edge are rare events. Most hours show zero. We log every single one we catch — including duplicates from the same market flickering open and closed — and never delete the past. This is the floor of the product, not the ceiling.
Pro subscribers get an email and Slack/Discord ping the moment a new arb hits the threshold you set. Most fire in seconds — having the alert first is the difference between catching the edge and missing it.
