Centband

Penny stock screener & organizer from Wood Between Studio · information only, not investment advice

Sort low-priced stocks by price, and see why each one is tagged

Centband is a calm, local screener and organizer for stocks under $5. With your own free Alpha Vantage key, the table opens already filled with U.S. stocks under $5 that are most active by volume — you don't have to type tickers first. You can also keep a watchlist of names you choose, group them into price bands (Under $1, $1–$3, $3–$5, or your own), and see which published rules each one meets: Unusual volume + move Meets 3+ checks Risky. Every tag lists the exact rules that fired and their numbers, and every price shows its source and quote time.

Centband is informational software, not investment advice. Wood Between Studio is not a registered investment adviser or broker-dealer. Centband is a tool for organizing and screening low-priced stocks. It is not a recommendation to buy or sell any security. Tags such as Unusual volume + move, Meets 3+ checks and Risky are rule-based descriptions, not recommendations. You are solely responsible for your own decisions. Market data is supplied by third-party providers or public filings, may be delayed or inaccurate, and is provided as is. Wood Between Studio is not responsible for the accuracy of that data and, to the fullest extent permitted by law, is not liable for any losses or actions taken based on the app. Please read the Terms of Use and About the data before you use it. Penny stocks are high risk and can be subject to fraud and manipulation.

Your data, your key

Centband doesn't sell or host market data. You connect your own free key from Alpha Vantage (about two minutes) to load the most-active-by-volume list, and optionally Finnhub and Twelve Data for names, market cap, the 52-week range, and volume. Your browser asks them directly; Wood Between Studio never sees your key or your watchlist. Filing checks come from the U.S. SEC's public EDGAR system. Read exactly how each number is sourced on About the data.
