VALUEDESK is a lightweight, zero-dependency, single-file value betting terminal that runs entirely in the browser. It automatically strips bookmaker margins from sharp reference lines (e.g. Pinnacle, Betfair Exchange) to compute true probabilities, expected value (EV), and recommended Kelly stakes.
No server, no Node.js, no build step, no npm dependencies.
- Sharp-Line Margin Removal (Devigging): Supports Shin (1993), Power, Multiplicative, and Additive margin stripping models.
- Ensemble & Quality Scoring: Analyzes model disagreement, sharp agreement, and line freshness to calculate a 0–100 signal quality score.
- Kelly Criterion Staking: Computes optimal stakes (Full, ½, ¼, ⅛ Kelly) with customizable bankroll caps and currency support.
- Interactive Bet Slip & Parlay Analysis: Evaluates accumulator/parlay growth versus single bets before placing.
- Bet Log & Automatic Settlement: Track stakes, ROI, and Closing Line Value (CLV). Automatically fetch finished match scores via API.
- Smart API Caching: Built-in credit management for The Odds API to fit within free tier limits.
- Offline / Demo Mode: Built-in synthetic market simulator for testing without an API key or credit consumption.
- 100% Client-Side: Your API keys, bankroll, and betting history stay entirely in your browser's local storage.
