Momentum Bell is a free, live-updating watchlist of US-listed stocks that are moving and drawing heavy trading activity right now.
From the market to your screen
Scanning. A scanner runs continuously during premarket, regular and after-hours sessions, looking across the market for stocks that meet a set of filters: a price range, a minimum percentage gain on the day, and a minimum dollar volume.
Measuring attention. For each qualifying stock, the system measures how actively it is trading in real time and turns that into the Momentum Bell Score. See how to read the score.
Publishing. Results are sent to a cloud database and this page listens for changes, so rows update within moments without reloading the page.
Dropping out. When a stock no longer meets the criteria, it leaves the main list and appears in the Dropped-out section with the largest gain it reached that day.
What’s on the page
All Movers and Focus. Two views of the same data: All Movers uses the broad filters, Focus applies a tighter set on top. Hover over a tab to see its current criteria.
Session badge and clock. Shows whether the US market is in premarket (4:00–9:30 a.m. Eastern), regular hours (9:30 a.m.–4:00 p.m.), after hours (4:00–8:00 p.m.) or closed, using an NYSE holiday calendar. The feed is empty when the market is closed.
Live indicator. Shows LIVE while the scanner is connected, and OFFLINE if the feed has been disconnected for several minutes.
Sound. An optional alert sound when a ticker’s score rises above 100.
Search, favorites, headlines. Type a ticker to filter the list, star tickers to pin them, and tap the 🗞 icon to see recent headlines.
How to read the watchlist
The watchlist is empty when the market is closed, so here is how the score colors, the All Movers and Focus buttons, and Sound look and work, using sample data.

Below 70Neutral70 – 100AmberAbove 100Green
GREENAbove 100 — High attention
What it means: This stock is among the busiest names on the list right now. Heavy trading activity is building around it, which is why it stands out from the rest.
What to do: Open the news and the chart, check the price, and compare Change% with Max Change to see how much of the move is already done. Above 500 the row lights up with a 🔥 fire banner. With Sound on, a rising alert sound plays when a score first crosses 100.
A high score means a stock is busy, not that its price will keep rising. Hypothetical screenshot with sample data.

AMBER70 – 100 — Building attention
What it means: Activity is picking up, but it hasn't reached the high-attention zone yet. Amber rows are worth keeping an eye on.
What to do: Watch the direction. A score that keeps climbing towards 100 can mean interest is building; one sliding back toward grey means it is fading. No alert sound plays yet; that comes when the score crosses 100.
Scores move from second to second, so judge the trend over a few minutes, not a single reading. Hypothetical screenshot with sample data.

NEUTRALBelow 70 — Neutral
What it means: The stock passes the filters (price, % change and dollar volume), but trading activity is ordinary right now. Most rows spend most of their time here.
What to do: Treat it as background. It becomes interesting when a neutral row starts turning amber or green.
Outside market hours the live list is empty. This is what it looks like when the market is open. Hypothetical screenshot with sample data.

VIEWSAll Movers and Focus: two views of one watchlist
What it means:All Movers is the full list of stocks that are passing the site's filters right now. Focus is a shorter list of the same stocks, narrowed down by a stricter filter, so you see fewer rows and less noise.
What to do: Start in All Movers for the wide view, and switch to Focus when you want a shorter list to watch. Point at either button on the live page to see its current settings. The score colors work the same way in both.
Both lists update live while the market is open. Hypothetical screenshot with sample data.

SOUNDSound alerts: hear it without watching the screen
What it means: With Sound on, the page plays a short rising alert sound each time a stock's score climbs above 100 into the green zone. There is no alert sound for amber or neutral rows.
What to do: Tap the Sound button at the top of the page to switch between Off and On, turn your device volume up, and keep the page open in a tab. Browsers only allow sound after you have tapped or clicked the page once, so switch it on yourself. A stock that dips just under 100 and comes back soon does not trigger the alert sound again, so you are not buzzed repeatedly.
Your Sound choice is remembered on this device. Hypothetical screenshot with sample data.
