What is an Altcoin Screener?
An altcoin screener is a tool that filters and sorts cryptocurrencies based on specific criteria — price change, volume, market cap, on-chain activity, or technical indicators. The goal is to surface coins that match your trading strategy from the thousands of altcoins available, saving hours of manual research.
Key Metrics to Screen For
- 24h price change: identify momentum and trending tokens
- 24h volume spike: unusual volume often precedes significant price movement
- Market cap range: filter by large-cap, mid-cap, or micro-cap depending on your risk tolerance
- 7-day performance: separate sustained trends from single-day spikes
- DEX activity: tokens with growing decentralized exchange volume may be early in their trend

Building a Screening Workflow
The most effective approach is a multi-step workflow: first, use broad filters to identify a watchlist of 10-20 candidates (e.g., gainers with increasing volume). Then, check each candidate on the Radar for DEX momentum signals. Finally, verify with the Whale Tracker for large wallet activity. This three-step process — screen, signal, confirm — reduces noise and improves trade quality significantly.
