jse-scraper 0.1.3

A high-performance, Playwright-powered scraper for the Jamaica Stock Exchange.

jse-scraper 🇯🇲

A robust, headless-browser Python library designed to extract real-time market data from the Jamaica Stock Exchange (JSE).

Because the JSE website uses dynamic JavaScript rendering and modern bot-protection, standard scrapers often fail. jse-scraper utilizes Playwright to mimic human browsing patterns, ensuring reliable data ingestion for your financial models.

🚀 Key Features

Dynamic Rendering: Automatically handles JavaScript-heavy tables that requests cannot see.

Stealth Mode: Mimics human behavior (scrolling, viewport management) to avoid firewall triggers.

Pandas Native: Returns data directly as a DataFrame for immediate quantitative analysis.

Auto-Cleanup: Sanitizes headers, removes currency symbols ($), and standardizes "Ordinary Shares" tables.

📦 Installation

Ensure you have a virtual environment active, then install the package and its browser dependencies:

Install the library (once published to PyPI)

pip install jse-scraper

Install the necessary Chromium browser for Playwright

playwright install chromium

🛠️ Quick Start

from jse_scraper import JSEScraper

Initialize the scraper

Set headless=False if you want to watch the 'Searcher' work in a window

scraper = JSEScraper(headless=True)

print("📡 Fetching Market Data from JSE...") df = scraper.get_trade_quotes()

if df is not None: # The library cleans headers automatically print(df[['Symbol', 'Last Traded Price', 'Volume']].head(10)) else: print("❌ Failed to retrieve data. Check your internet connection.")

📊 Why use a Headless Browser?

Most Caribbean stock exchange websites do not provide free public APIs. They rely on "Server-Side Rendering" or "Hydrated States" where data is injected into the page after it loads.

jse-scraper solves this by:

Launching a headless Chromium instance.

Navigating to the Trade Quotes page.

Waiting for the "Ordinary Shares" section to fully render.

Capturing the DOM and parsing it via lxml for maximum speed.
