PSX Intelligence
AI-powered financial analysis platform delivering real-time insights into Pakistani stock market data.
Problem
Individual investors and institutional traders needed actionable insights from the Pakistan Stock Exchange (PSX). Raw data is abundant but difficult to parse—sentiment analysis, anomaly detection, and predictive signals require expertise and time. The market moves fast, and delays in analysis mean missed opportunities or uninformed decisions.
Solution
PSX Intelligence combines real-time data collection, AI-driven analysis, and a clean user interface. The platform ingests market data, applies machine learning models for pattern recognition, and surfaces high-value signals to users through an intuitive dashboard.
Key features include: live ticker updates, AI-generated sentiment analysis, anomaly detection flagging unusual trading patterns, predictive signals based on historical data, and watchlist management.
System & Architecture
Backend: Node.js API with PostgreSQL for historical data storage. Real-time WebSocket connections for live ticker updates. Background jobs process incoming market data and feed AI models.
AI/ML: LLMs for sentiment analysis, time-series models for anomaly detection, ensemble approaches for signal generation. Models run asynchronously and results are cached for fast dashboard queries.
Frontend: React with TypeScript, real-time updates via WebSocket, responsive design for mobile traders, dark mode optimized for market monitoring.
Key Technical Decisions
Real-time vs. Batch
Chose hybrid approach: real-time ticker updates via WebSocket for responsiveness, but heavy ML models run on scheduled batches to manage computational load. Users see latest data immediately with refreshed analysis every 5 minutes.
Data Storage
PostgreSQL for reliability and query flexibility. Time-series data is partitioned by date for optimal query performance. Archive older data to cold storage after 6 months.
Model Reliability
All AI models have fallback logic. If a model fails or produces invalid output, the system surfaces the raw data with a transparency note. Trust is earned through reliability first, features second.
Outcome & Current State
PSX Intelligence is live with 500+ active users. The platform has proven reliable during high-volatility market events, maintaining real-time updates even during trading halts and market surges.
User feedback highlights the speed of signal generation and accuracy of sentiment analysis. The platform has detected several market anomalies before traditional analysis caught them.
Future work includes expanded model coverage, mobile app refinement, and institutional API access.
