Top Movers Scanner
Top movers show symbols with meaningful intraday percentage movement and sufficient liquidity. The scanner emphasizes quality by combining movement, dollar volume, and real-time market-session logic.
Reviewing movers alongside RVOL helps avoid chasing flat-volume spikes and improves context for entries, exits, and risk control.

The free real-time RVOL scanner & halt tracker
This dashboard watches the whole US market and flags stocks the moment they trade on unusually high relative volume (RVOL), the earliest tell that a stock is in play. Alerts fire live through premarket, regular hours, and after-hours, alongside a real-time halt tracker, top movers, and 200 EMA signals. It is the same scanner that powers our leaderboards and per-ticker feeds.
Frequently asked questions
- What is the RVOL scanner?
- A real-time scanner that flags stocks trading on unusually high relative volume (RVOL), the earliest sign a stock is in play. It updates live through premarket, regular hours, and after-hours.
- What are halt alerts?
- Notifications the moment a stock is halted (volatility, news, or LULD) and again when it resumes trading, so a stopped ticker never blindsides you.
- How is relative volume (RVOL) calculated?
- It compares a stock’s current cumulative volume to its own average for the same time of day. Roughly 2x is unusual and 5x or more is a strong signal of institutional or retail interest.
- Is the scanner free?
- Browsing live alerts is free for 5 days, then premium at $24.99 per month. The public RVOL and top-mover pages stay open to everyone, and you can add any ticker to a watchlist for personal alerts.
