pypsx

Programmatic, API-first access to the Pakistan Stock Exchange (PSX). The official Python SDK for pyPSX.

pyPSX is the trading platform for PSX, and it is API-first: everything is available programmatically over a REST and WebSocket API, through this Python SDK, and in a point-and-click web terminal. This is not just a library. The platform gives you free market data, backtesting on 10+ years of history, a paper-trading sandbox, live real-money trading, a live market feed, and an AI Strategy Copilot. This package is the authenticated Python SDK that ties into all of it.

What this package does

pypsx is the authenticated Trading SDK. With one free API key it gives you:

• Historical and intraday PSX market data.
• Backtesting on 10+ years of history, with realistic commission and slippage.
• A free paper-trading sandbox with a real fill engine and FIFO lot accounting.
• Live real-money trading on your own account after standard KYC onboarding.
• A live market feed over WebSocket.
• Strategy Copilot configs that turn plain English into a runnable bot.

The same capabilities are available over REST and WebSocket, and inside the pyPSX web terminal, so you can work in code or point-and-click, whichever fits.
