What Is a Momentum Scanner?
A momentum scanner is a tool that automatically screens thousands of stocks and crypto assets to identify which ones are building momentum before a major price move. Unlike static screeners, momentum scanners detect dynamic patterns like volume surges, price compression, and social sentiment acceleration in real time.
How It Works
A momentum scanner runs continuously, pulling live market data and scoring each asset against momentum criteria. Most scanners track a combination of technical indicators (RSI, MACD, moving averages), volume patterns, and price action. Advanced scanners like Banana Farmer also incorporate social sentiment data from platforms like Reddit and financial news feeds.
The scanner ranks assets by momentum strength and surfaces the top-scoring ones. Instead of manually reviewing hundreds of charts, you get a ranked list updated every 15 minutes. Read the full breakdown in our deep-dive guide to momentum scanners.
Example
A small-cap biotech stock starts showing 2x its normal volume on a Tuesday morning. RSI climbs from 48 to 63. Social mentions on Reddit triple overnight. Individually, none of these signals are dramatic. But a momentum scanner detects the convergence, scores the stock in the top 20 out of 9,000+ tracked assets, and flags it as “Ripening.” By Thursday, the stock is up 12%. Traders who spotted it on the scanner's ranked list had a two-day head start.

Frequently Asked Questions
How is a momentum scanner different from a stock screener?
A stock screener filters by static criteria you set (price above $10, volume over 1M). A momentum scanner actively detects dynamic patterns like accelerating volume, tightening price ranges, and social sentiment shifts. Screeners wait for you to define rules. Scanners find emerging setups automatically, often before they meet any fixed filter criteria.
Do momentum scanners work for crypto?
Yes. Momentum scanners that track technical indicators and volume work across any liquid market. Banana Farmer scans 9,287 stocks and 125 crypto assets using the same scoring framework. Crypto tends to show faster momentum cycles (hours to days vs. days to weeks for stocks), so the scanner updates every 15 minutes to catch those shorter windows.
Are momentum scanners useful for beginners?
Very useful. Beginners typically lack the experience to spot momentum building from raw charts. A scanner compresses that learning curve by surfacing setups automatically and explaining why each asset is scoring high. Instead of watching 50 charts, you review a ranked list. Banana Farmer's free tier gives you access to the top signals so you can start learning the patterns.
