Margin = Margin (Overround) · I = Implied Probability · NM = No-Margin Probability · EV = Expected Value · E = Edge · K = Kelly Criterion · G = Bankroll Growth

Updated is when each book last changed its price, so an older time means the odds simply haven't moved, not that the price is stale. Books not seen in the last ~15 minutes are normally dropped; only if a whole market's feed goes quiet are the latest recorded prices shown instead.
