About Stock Monitor
A free, comprehensive stock analysis and portfolio monitoring platform built specifically for individual investors and active market participants.
🎯 Our Mission
Stock Monitor is a free stock analysis and portfolio monitoring platform designed for individual investors. The platform combines technical indicators, portfolio tracking, market scanning, historical performance analysis, and AI-assisted market insights in one place.
Stock Monitor was created to make market analysis easier by bringing commonly used investment tools together in a single application. Historically, retail investors had to juggle fragmented tools: one platform for charts, another for momentum screener alerts, a third for portfolio calculations, and expensive proprietary terminals for macro context. Stock Monitor unifies these essential capabilities into a responsive, high-speed, and modern interface.
Stock Monitor is an independent project and is not affiliated with, sponsored by, or tied to any brokerage firm, investment bank, hedge fund, market maker, or financial institution. We sell no financial products, accept no order-flow kickbacks, and offer unbiased quantitative tools for educational self-directed study.
💡 What Powers Stock Monitor
Our platform is architected around five core functional pillars designed to deliver actionable market intelligence without information overload:
Technical Indicators
Real-time calculation of key momentum and trend metrics including RSI (14), MACD with signal crossovers, short and long Exponential Moving Averages (EMA 20/50), and dynamic support/resistance levels.
Real-Time Scanner
Quantitative screening engine that scans market tickers across the US and Canadian exchanges to spot oversold bounces, bullish MACD crossovers, and volume momentum setups.
Portfolio Tracking
Mark-to-market portfolio accounting with support for multi-currency positions (USD & CAD), cash balance tracking, automated P&L breakdown, and imported transaction ledgers.
AI-Assisted Insights
Quantitative diagnostic models and LLM integration (Google Gemini) that generate structured trade post-mortems, catalyst breakdowns, and daily morning briefings on macro drivers.
Trade Simulator
Risk-free paper trading engine allowing traders to validate strategies, track simulated executions, and evaluate expectancy without risking real financial capital.
Privacy-First Architecture
Your portfolio data, trade ledger, and API preferences are stored locally in your browser (LocalStorage). We do not store your private financial transactions on our servers.
⚙️ Engineering & Architecture
Stock Monitor is engineered for speed, low latency, and zero friction:
- Client-Side Quantitative Computation: Technical indicator mathematics (EMA, RSI, MACD histograms, ATR multipliers) execute directly in the client's browser, eliminating server bottlenecks and enabling instant parameter tuning.
- High-Fidelity Financial Charting: Interactive candlestick charts, volume histograms, and overlay curves powered by industry-standard lightweight charting frameworks.
- Intelligent Two-Tier Caching: The Node.js proxy backend implements memory caching with stale-fallback resilience, ensuring rapid response times while respecting market data rate limits.
- Zero Account Required: Start analyzing stocks and tracking your watchlist immediately without cumbersome signup walls or sharing personal identification.
