📉 US Short Interest Scraper: NYSE, Nasdaq and OTC via FINRA Data

Short interest for every US ticker, not just the Nasdaq ones Official FINRA data for NYSE, Nasdaq, NYSE Arca and OTC securities. Short interest, days to cover, and period change, going back to 2017.

🏛️ Every US market NYSE, Nasdaq, Arca and OTC. Tickers like IBM and SPY that Nasdaq-only tools miss entirely.

📅 History back to 2017 Over 200 settlement periods, not the twelve months most tools stop at.

🎯 Backtest-safe dates Every row carries the date the figure actually became public, not just the settlement date.

🔔 Quiet until it matters Monitor mode returns nothing until a genuinely new period publishes.

Pull official short interest data straight from FINRA, the regulator that collects it. Export to JSON, CSV or Excel, or connect it into Google Sheets and your own pipeline via the API. Run it on demand or on a schedule. No account, no API key, no coding required.

✨ Why use this Actor

Built for anyone who needs short interest as data, not as a web page.

• 📊 Quant and systematic traders: backtest crowding and squeeze signals on more than 200 settlement periods, with a date field that keeps hindsight out of your results.
• 🔍 Squeeze watchers: track days to cover and period-over-period short interest changes across a whole watchlist in one run.
• 🧑‍💻 Fintech and app builders: a clean, structured short interest feed to power your own screener or dashboard.

Coverage is the difference. Other short interest scrapers on the Store read Nasdaq's own site, so NYSE and Arca tickers such as IBM and SPY come back empty. This Actor reads FINRA's consolidated data, which covers every US market in one place.

⚙️ How it works

STEP 2 Pick a period The latest settlement period, or any historical range back to 2017.

🛠️ Tips for better runs

• Short interest publishes twice a month, on the 15th and the last business day, and appears about seven business days later. Schedule around that rhythm.
• Turn on monitor mode for scheduled runs. It stays silent until a new period lands, so you never pay for duplicate rows.
• For a whole-market pull, leave symbols empty and raise maxItems. A single settlement period covers thousands of securities.
• Sort by daysToCover in the squeeze view, but filter out rows where daysToCoverIsCapped is true first.

❓ FAQ

Does this include cost to borrow or short percent of float? No. FINRA publishes short interest, average daily volume and days to cover, and this Actor reports exactly those. Cost to borrow, percent of float and utilization come from other sources and are not included.

Why do other short interest scrapers return nothing for IBM or SPY? They read Nasdaq's own site, which only carries Nasdaq-listed securities. This Actor reads FINRA's consolidated data, so NYSE, NYSE Arca and OTC securities are all covered.

How accurate is the knowable date? It applies FINRA's published schedule of seven business days after settlement. It counts weekends but not market holidays, so in a holiday week the real publication date can be a day later. It is a close guide, not an exact timestamp.

Is it legal to use this data? Short interest reporting is required of broker-dealers under FINRA rules, and FINRA publishes the results as public data. This Actor reads that public source. You are responsible for how you use the data.

How far back does the history go? To late 2017, covering more than 200 settlement periods. Turn off "latest settlement period only" and set a date range to pull history.
