Bulk Stock Ticker Price Checker Across Portfolio

WHAT IT DOES

Bulk Stock Ticker Price Checker Across Portfolio solves a common investing challenge: checking prices and market data for multiple stock tickers is tedious when done one at a time across different websites or apps. This tool lets you enter a list of stock ticker symbols (comma-separated or line-separated) and fetches current price and market data for each symbol from a public financial API (Yahoo Finance). Results are displayed in a scrollable checklist with symbol, current price, day change, percent change, volume, market cap, and day high/low. Color-coded indicators make it easy to identify performance: green for positive change, red for negative change, and gray for no change or errors. You can filter results by price change status, view a preview of tickers before checking, and export the complete dataset as CSV or JSON.

WHERE IT RUNS

This extension panel runs directly inside your browser as an overlay on any web page. It works independently of any specific site and requires no additional API keys or permissions beyond the BotGentz extension. The tool fetches data from a public financial API, making it usable from any browser session.

HOW TO USE

After installing the BotGentz extension and activating Bulk Stock Ticker Price Checker Across Portfolio, click the extension icon in your browser toolbar to open the panel. Enter your stock ticker symbols in the text area — you can separate them by commas or new lines. For example: "AAPL, MSFT, GOOGL, TSLA" or each on its own line. The preview section shows how many tickers you've entered. Click "Check Prices" to begin fetching data. The tool processes each ticker sequentially with a 400ms delay, showing live progress updates. Results appear with color-coded status indicators and show price, change amount, change percentage, volume, and market cap. Use the filter dropdown to view only tickers that went up, down, or returned errors. Click "Export Report" to copy the complete dataset to your clipboard in CSV or JSON format. Click "Clear" to reset the panel.

TECHNICAL OPERATION — Financial API Data Fetching and Parsing

This tool uses Yahoo Finance's public API endpoint (`query1.finance.yahoo.com/v8/finance/chart/{ticker}`) to fetch real-time market data for each ticker symbol. The response is parsed to extract current price, change, change percentage, volume, market cap, day high, and day low. The tool handles API response parsing with robust error handling for invalid tickers, network errors, and timeouts. A 400ms delay between requests prevents rate limiting and API congestion. Results are categorized by price change direction (up, down, unchanged) and error status. The tool stores ticker history locally for convenience. Results can be exported as CSV with proper field quoting for Excel compatibility, or as structured JSON for programmatic use.

THE PANEL

The extension panel is fully draggable and remembers its position per site session. It snaps to the nearest edge of the browser viewport when dragged within 50 pixels of any side. You can collapse the panel to a compact title bar using the minimize button, preserving your selection state. The panel resizes vertically by dragging the bottom edge. Press the Escape key to close the panel instantly. The preview updates in real-time as you enter tickers, and the results section updates as fetches complete.

PLEASE NOTE

This tool requires the free BotGentz extension to function. The script fetches stock data from a public financial API and does not store, transmit, or log any ticker data, prices, or user activity. All operations are performed locally from your browser session. The Yahoo Finance API is a public endpoint and may have rate limits or availability changes. Data is for informational purposes only and may be delayed; the tool is not a substitute for professional financial advice. The tool uses a 400ms delay between requests to prevent rate limiting. Ticker symbols are case-insensitive and are normalized to uppercase. Export formats include CSV and JSON for maximum compatibility with analysis tools. Some tickers may return errors if they are invalid or not available on the API. Always verify critical financial data through official sources before making investment decisions.
