Technical Indicator Screener — US Stocks via Finviz

Technical Indicator Screener screens US stocks by 18 technical indicators using Finviz — RSI, MACD, SMAs (20/50/200), Bollinger Bands, golden/death cross, and trend classification. Two modes: screener (find stocks matching filters) and tickers (analyze a specific watchlist). No API key required. $0.02/stock.

Finviz's free screener is the most widely used technical scanning tool in retail trading. This actor makes it programmatically accessible — schedule daily pre-market scans, build custom alert systems, and pipe results into trading workflows without manual browser use.

Why use Technical Indicator Screener?

1. Daily pre-market momentum scanning — Run rsi_oversold + high relative volume every morning to find potential reversal setups before market open. High-volume oversold stocks with improving technicals are a classic bounce setup.
2. Automated breakout detection — Filter new_high + above_sma200 + above_sma50 to find stocks making new highs with clean technical structure. Schedule hourly during market hours.
3. Watchlist technical dashboard — Run in tickers mode on your portfolio or watchlist. Get RSI, MACD position, SMA relationships, and 52-week range position for every holding in one batch.
4. Golden/death cross alerts — Schedule daily runs with golden_cross or death_cross filters to catch major trend change signals across the entire US market as they develop.
5. Sector technical rotation — Use marketCapFilter: "cap_large" with above_sma50 to track which large-cap sectors are in uptrends — a classic systematic sector rotation signal.

FAQ

Does Finviz update intraday? Finviz's free screener updates throughout the trading day, typically with a 15-minute delay. For intraday momentum scans, run the actor multiple times during market hours.

Can I combine multiple filters? Yes — set filters: ["rsi_oversold", "above_sma200"] to require all conditions. Multiple filters use AND logic (stock must match all).

How does relative_volume work? relative_volume = today's volume / average daily volume. Values above 1.5 indicate unusually high trading activity — often associated with news catalysts or technical breakouts.

Is this US stocks only? Yes — Finviz covers US-listed stocks (NYSE, NASDAQ, AMEX). For crypto technical indicators, see Altcoin BTC-Relative Performance or Long/Short OI Aggregator.
