QuantVision Engine

QuantVision Engine — Full-Stack Confluence Trading Platform

QuantVision Engine is an automated confluence trading and technical pattern recognition engine built for the XAU/USD (Gold) market. The platform computes 6 technical indicators in real-time and synthesizes them into a single confluence score (0-100%) to generate actionable BUY/SELL/NEUTRAL signals.

The system features a FastAPI backend that fetches live market data via yfinance, computes indicators using custom NumPy/Pandas-based algorithms, and streams updates through WebSocket connections. The React frontend renders professional-grade TradingView charts with real-time overlays for all indicators.

Architecture

• Backend: Python FastAPI — REST API endpoints + WebSocket streaming for live market data
• Frontend: React 19 + Vite — Interactive dashboard with TradingView Lightweight Charts
• Data Pipeline: yfinance → NumPy/Pandas computation → In-memory cache → WebSocket broadcast
• Deployment: Full-stack served from single FastAPI instance with static file mounting

6-Indicator Confluence System

The engine computes and weighs 6 independent technical indicators, each contributing to the final confluence score:

• Ichimoku Kinko Hyo (20% weight) — Trend filter using Tenkan-sen, Kijun-sen, Senkou Span A/B, and Chikou Span for comprehensive trend analysis and cloud-based support/resistance.
• MA 9/10 Crossover (20% weight) — Momentum trigger detecting golden/death crosses between 9-period and 10-period moving averages.
• ZigZag Market Structure (20% weight) — Market structure analysis identifying Higher Highs/Lower Lows patterns for trend confirmation.
• Stochastic Oscillator (20% weight) — Momentum oscillator detecting overbought/oversold conditions with %K/%D crossover signals.
• RSI (10% weight) — Relative Strength Index for momentum confirmation with configurable overbought/oversold thresholds.
• Tick Volume (10% weight) — Volume confirmation requiring above-average volume to validate signals.
