Why the result list stays focused

This is an event screen, not a broad state filter. A symbol must satisfy the phase change and the current-session participation test at the same time. Medium-liquidity gating and ETF exclusion are applied when it runs.

How to use it

Review the chart and catalyst, remove names that fail your risk rules, save the survivors to a watchlist, and publish a frozen result snapshot when the list is worth discussing.

Backtest context

Event screen; validate before use. Historical results are not a promise of future performance; customize the rules and validate them against your own holding period and costs.
