Biggest movers

Ranked by size of the move, up or down. We don't have volume data, so this isn't “most active,” just the largest percentage swings.

Universe: distinct US and Canadian tickers with an insider filing, a Congress trade, or a CIRO short-interest report in the last 45 days, ranked by most-recent activity and capped at 200, refreshed every 20 minutes through pre-market, the regular session, and after-hours via Yahoo's public quote endpoint. This is deliberately not the full market, and there's no sector heatmap here: this database has no sector or industry data, so rather than invent one, we're shipping gainers/losers/biggest movers only. Every ticker links through to its full page with insider activity, short interest, and the Work Order verdict. Not investment advice.
