Q Screener and Daily Alerts

Daily-close quantile comparisons, seven-session forecasts and saved filters.

Daily scan

A scan is scheduled after each NYSE close (normally 4 pm New York). The calendar gate handles DST, holidays and early closes. GitHub scheduling and inference take time; publication follows coverage validation.

The latest completed daily close is included—no withheld session or minute tracking. Seven future trading sessions use Prophet, Toto 4M, Granite, Chronos-2 and TimesFM, each with 20% central weight. Unsupported tails are reweighted. Quantiles: P01/P10/P25/P50/P75/P90/P99. No fabricated fallback.

Price and quantile comparisons

The screener shows the latest completed daily close beside the first future P01/P10/P25/P50/P75/P90/P99 values. Above/below quantile and min/max/average filters are descriptive comparisons, not buy/sell recommendations. Prices are split-adjusted. Trade-signal filters and labels have been retired; old saved signal-based alerts are paused and can be removed and recreated with quantile filters.

Browse recent scans

The screener keeps each validated stock scan for 14 calendar days. Use the date picker or Previous day / Next day to visit published dates; days without a completed scan are unavailable. Search, quantile, sort and CSV-export filters apply to the selected date. The count is the number of markets matching those filters. Historic rows use their saved close and forecast, not today’s quote. Kalshi perpetuals remain on demand and have no dated screener forecast archive.

For programmatic reads, pass date=YYYY-MM-DD to GET /api/screener/data or GET /api/screener/export.csv. The JSON response includes availableDates and selectedDate. An unavailable date returns screener_snapshot_not_found (404); the service does not synthesize a scan.

Filters and alerts

Combine min/max/average quantiles with AND rules. “Average P50 > 10% above price” means 100 × (average P50 - daily close) / daily close > 10.

Save filters & alerts requires sign-in; maximum ten filters. Email is opt-in to your verified address. Remove a filter to stop alerts. Matching rows enter the inbox once per input trading date, with one combined email subject to delivery limits. No location is needed.

Reading needs alerts:read; saving/removing needs alerts:write. View forecast opens the published snapshot without inference. Save to profile preserves a private copy; workspace permissions apply. Public stock scan links remain available while their dated asset is in the 14-day archive; saved profile copies remain after that window.

Brevo uses the approved Fixie proxy. Sends are durably deduplicated and subject to the shared allowance; provider acceptance does not prove inbox delivery.
