Crypto Volume and Momentum Scanner: Anomaly Signals

Scan the crypto market for unusual volume and momentum: turnover, 1h/24h/7d momentum and an anomaly classification, scored and ranked. Self-serve crypto screener for traders.

Spot the coins that are moving before they hit your feed. Scan the crypto market and get a ranked list of unusual volume and momentum: turnover (24h volume vs market cap), 1h/24h/7d momentum and a clear signal classification - volume breakout, capitulation, strong weekly momentum or unusual volume at a flat price. A curated screener signal, not a raw market dump.

What it does

  • Turnover: 24h volume divided by market cap, the clearest single measure of unusual activity.
  • Adaptive scoring: turnover is percentile-ranked within the scanned universe, so the score adapts to market conditions.
  • Momentum blend: 1h / 24h / 7d change combined with turnover into one impact score (0-100).
  • Signal classification: volume breakout (rising), volume capitulation (falling), strong weekly momentum, or unusual volume at a flat price.
  • Stablecoins filtered out so they do not pollute the ranking.

Who uses a crypto screener

  • Crypto traders and quants building watchlists and anomaly alerts.
  • Fintech and research apps embedding a scored momentum/volume feed.
  • Researchers wanting a clean, reproducible snapshot of market-wide activity.

How it works

The tool reads the official CoinGecko markets API (free, public, JSON), filters stablecoins, computes turnover and momentum, percentile-ranks each coin within the scanned universe, and classifies the signal. Clean and stable.

Example

WLD in live data: "Volume breakout (rising)", up ~8.8% in 24h and ~20% in 7 days on heavy turnover, scored impact ~79. Highest-signal coins rank first.

Scope and limitation

This is a market-data screener (price and volume), not on-chain "smart money" wallet tracking - there is no clean, free, public source for labeled-wallet flows, so this Actor deliberately stays on transparent, reproducible market metrics.

FAQ

What is turnover?

24h trading volume divided by market cap. High turnover means a coin is changing hands unusually fast for its size.

Why are stablecoins missing?

They are filtered out on purpose; their constant high volume would otherwise dominate the ranking.

Is this investment advice?

No. Crypto is volatile; this is data for research and monitoring.

Use with AI agents and automation

This runs as an Apify Actor, so it drops into your stack with no scraping or glue code: - AI agents and LLMs: call it as a live tool from LangChain, LlamaIndex or Flowise, or over MCP. - No-code automation: wire it to Zapier or Make (new volume breakout -> Slack, Google Sheets or alert). - Webhooks and pipelines: fire a webhook on each run, or chain it into another DataSignals Lab product. - API and schedule: JSON output, on demand or on a daily schedule.
