About ProScreeners

ProScreeners is a collection of pro-grade market screeners for crypto, crypto perpetual futures, US stocks, ETFs and CME futures, and every one of them is free. They run entirely in your browser: no account, no download and no subscription.

Why it exists

Good screeners usually sit behind a paywall or a sign-up form. ProScreeners puts the scans traders use every day (gainers and losers, unusual volume, 52-week highs and lows, RSI extremes, moving-average crossovers, gaps, volatility squeezes, momentum setups, market caps, funding rates and options flow) on simple pages that load in seconds.

How it works

Your browser downloads market data straight from the provider and works out every indicator itself. Each technical screener has a market switch and opens on crypto:

  • Crypto: the public market-data API of Binance (Binance.US as a fallback), plus CoinPaprika for market caps. No key.
  • Crypto perps: OKX’s public API for USDT perpetual futures, and Hyperliquid for funding rates. No key.
  • Crypto options: Deribit’s public API (BTC, ETH, SOL, XRP, AVAX, TRX and HYPE options), with OKX as a fallback. No key.
  • US stocks, ETFs and US options: Alpaca, using a free market-data key you add once and that stays in your browser (how to get one).
  • CME futures: Massive (formerly Polygon.io), using a free API key you add once (how to get one).

Optional auto-refresh (off until you turn it on) updates results in place while you watch, pauses when the tab is hidden, and stops after half an hour without activity, so an idle tab doesn’t keep downloading data.

ProScreeners is the sister site of FreeCharting, which offers free charts with indicators and drawing tools. Click any symbol in a screener to open its chart there.
