Notable Trades

Serial trader adds to quiet-market No

A serial cross-market trader added a sizable No position in a very quiet market, though their long-term record does not show a clear odds-adjusted edge.

This wallet has traded across 77 events and 157 markets, with 723 resolved bets and $111,158 in reported profit.
The 63% win rate is notable, but the 72¢ average winning entry suggests the historical edge is not clearly strong.
