# Nasdaq Short Interest Tracker — Official Data (`bovi/nasdaq-short-interest-tracker`) Actor Scrape official Nasdaq short-interest reports for any stock or ETF ticker: settlement-date short interest, average daily volume, days-to-cover, and period-over-period change (computed, not left blank). Official Nasdaq data, no login, no API key.

You are not charged for the Apify platform usage, but only a fixed price for specific events. Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Nasdaq Short Interest Tracker Official Nasdaq short-interest data for any stock or ETF ticker — settlement-date short interest, average daily share volume, days-to-cover, and **period-over-period change, computed for you** (most competing tools declare this field and leave it blank). **No API key. No login. No paywall.** This is Nasdaq's own publicly disclosed exchange data (the same bi-monthly short-interest report every US listed security files), read straight from the JSON endpoint that powers `nasdaq.com/market-activity/{stocks|etf}/ {symbol}/short-interest`. Pay per result. --- ### What data you get One record per settlement date, per symbol: - `symbol` — ticker, uppercased - `assetClass` — `stocks` or `etf` - `settlement_date` — MM/DD/YYYY, as published by Nasdaq (bi-monthly) - `short_interest` — shares held short as of the settlement date - `avg_daily_volume` — average daily share volume for the settlement period - `days_to_cover` — `short_interest / avg_daily_volume` - `change` — `short_interest[this period] - short_interest[prior period]`. **Computed from the same history the API already returns** — no extra request, no guesswork. `null` only for the oldest settlement date in the returned window (no prior period exists to diff against). - `scrapedAt` — ISO 8601 UTC scrape time - `parse_confidence` (0.0–1.0) and `warnings` — machine-readable data-quality signal Nasdaq's endpoint returns roughly the last ~24 settlement dates per symbol (~2 years of bi-monthly history) in one call — no pagination needed. --- ### Input | Field | Type | Description | |---|---|---| | `symbols` | array of strings | Ticker symbols, e.g. `["AAPL", "TSLA"]`. | | `assetClass` | `stocks` \| `etf` | Must match how the symbols trade — Nasdaq's API is keyed by asset class. | | `maxItems` | integer | Max settlement-date records returned **per symbol**, newest first. `0` = all available (~24). Default `10`. | | `proxyConfiguration` | object | Apify Proxy — works out of the box, Residential is the default group. No setup needed. | Example: ```json { "symbols": ["AAPL"], "assetClass": "stocks", "maxItems": 10 } ```` *** ### Why this actor Existing short-interest scrapers pull the same official numbers but leave the period-over-period `change` field empty even though it's a one-line subtraction once you have two consecutive settlement dates for a symbol — which the source API already hands you in a single call. This actor computes it, so you don't have to diff the history yourself downstream. No proxy key, no unlocker key, no credentials required from you — the actor works out-of-the-box on your own Apify account. # Actor input Schema ## `symbols` (type: `array`): Nasdaq ticker symbols to fetch short-interest history for, e.g. AAPL, TSLA, MSFT (stocks) or QQQ, SPY (ETFs — set Asset class to ETF). ## `assetClass` (type: `string`): Whether the symbols above are stocks or ETFs. Nasdaq's short-interest API is keyed by asset class — mixing the wrong class with a symbol returns no data. ## `maxItems` (type: `integer`): Maximum number of bi-monthly settlement-date records to return per symbol, newest first. 0 = all available (Nasdaq publishes roughly the last ~24 settlement dates, ~2 years of history). Default 10. ## `proxyConfiguration` (type: `object`): Apify Proxy is used for every request out of the box — no buyer setup needed. Residential proxy is the default and recommended group. ## Actor input object example ```json { "symbols": [ "AAPL" ], "assetClass": "stocks", "maxItems": 10, "proxyConfiguration": { "useApifyProxy": true, "apifyProxyGroups": [ "RESIDENTIAL" ] } } ``` # Actor output Schema ## `results` (type: `string`): Dataset containing Nasdaq Short Interest Tracker records (symbol, assetClass, settlement\_date, short\_interest, avg\_daily\_volume, days\_to\_cover, change, scrapedAt, parse\_confidence). # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "symbols": [ "AAPL" ], "assetClass": "stocks", "maxItems": 10, "proxyConfiguration": { "useApifyProxy": true, "apifyProxyGroups": [ "RESIDENTIAL" ] } }; // Run the Actor and wait for it to finish const run = await client.actor("bovi/nasdaq-short-interest-tracker").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
