Data updates & coverage

Momentum Screener is designed for long-term momentum analysis, so accuracy and cadence matter more than split-second ticks. Here is how we keep data current.

Daily refresh schedule

• Ranking refresh – We recalculate momentum scores and update every list between 6:30–7:00 PM ET after the U.S. market close.
• Corporate actions – Splits, dividends, and symbol changes are reconciled overnight so the next session opens with clean history.
• Economic calendar & watchlists – Macro notes and saved lists sync continuously so they are ready when you log back in.

If the market is closed for a holiday, we run the pipeline after the next full session so momentum windows stay aligned with trading days.

Coverage universe

• Equities – All U.S.-listed common stocks plus the most liquid international ADRs.
• ETFs & mutual funds – Core sector, factor, and bond ETFs along with a curated list of mutual funds requested by subscribers.
• Custom lists – Edge subscribers can upload CSV watchlists. Symbols that are not in our default universe are queued for review and typically added within one business day.

Data providers & quality checks

We blend multiple licensed feeds and reconcile them before publishing ranks:

1. Ingest raw pricing, volume, and corporate action data.
2. Run validation checks (missing bars, stale prices, outliers) and flag anything suspicious.
3. Recompute rolling return windows and risk metrics.
4. Publish the new ranks and alert systems that power watchlists, drawdown lists, and email summaries.
