For each territory, we track the top 1000 most actively traded stocks, ranked by their 5-day volumes.


Traders use Stockbeep to discover price events and volume flows during the trading session.

New highs

Price events that traders look out for typically include new highs/lows. These could mean all-time highs or 52-week highs.

It could also mean monthly highs.

The New Highs scan tracks all-time, 52-week and monthly highs, helping traders discover stocks with significant new highs today.

Continuous updates

The scans update every 5 seconds during regular trading hours. To get the latest results for any scan, sort by Time. This will display stocks ranked by the timestamps of their latest highs/lows.

Price breakouts

Traders are often on the lookout for “breakout stocks". These are stocks where prices are showing a sharp upward move.

The Breakout Stocks scanner

The methodology that we use, is the 5-day range. When a stock moves above its 5-day range by one standard deviation, it gets displayed on the scanner.

Volume flows

Traders also look out for increased volume flows. The industry term would be “unusual volume", “high relative volume (RVol)" or “volume spike".

volume flows

Elevated volume flows typically signal that there is something going on today, or that the stock “is in play" today.

The Unusual Volume Stocks scan identifies stocks with increased trading activity today.
