A strategy is a rule that can be tested against settled markets: buy one side of markets on a venue, in a category, priced in a 10-cent band, some days before they close. Its result is what those markets actually did.
A rule is listed only with at least 100 settled markets, a return of 3% or more before fees, and an edge on at least one horizon. Rules are ranked by return_low_usd, so a large sample with a steady edge outranks a lucky small one.

Markets that fit now

Matches are listed markets on the rule’s venue and category, with a Yes ask inside its band, closing near its horizon, and not yet under way. Each carries the ask for the rule’s side.
Returns are historical and before fees, and use each band’s average midpoint rather than the ask you would have paid. Bands below 10¢ and above 90¢ are left out because that far out the ask sits too far above the midpoint for the return to be reachable. History is not a forecast.
