# TendiesIQ > Prove you can read the market. A public, verifiable leaderboard for chart-reading skill built on real historical market data. Free. No signup. No real money. ## Summary TendiesIQ is a chartist credibility platform disguised as a game. Players receive unmarked real-market historical charts (ticker hidden until resolution), predict UP, SIDEWAYS or DOWN with optional target prices or ranges, then watch the actual historical bars that followed. Scoring rewards correct direction and boldness (farther targets pay more on hits and cost more on misses). Wrong calls deduct points. Streaks multiply scores. All data is real OHLCV history cached at deploy time from Yahoo Finance — no synthetic prices, no live third-party calls during gameplay. The public leaderboard ranks players by net points. Every player gets a stable /u/ public profile page and a shareable OG image card. The explicit goal is a third-party "receipt" traders and influencers can link in their bios so followers can verify skill instead of trusting screenshots. ## Who it's for - Trading influencers and content creators who want a public, tamper-proof track record. - Aspiring traders building proof before claiming expertise. - Anyone who wants to vet calls they see on Twitter, YouTube, Discord, Reddit, etc. - Casual chart readers who enjoy the puzzle and the competitive leaderboard. ## Key pages - https://tendiesiq.com/ — pitch + live demo of the game loop - https://tendiesiq.com/play — the main Quickplay experience (full-screen mystery chart + UP / SIDEWAYS / DOWN) - https://tendiesiq.com/leaderboard — live public rankings, filterable by timeframe - https://tendiesiq.com/faq — detailed rules, scoring math, levels, sync, data provenance - https://tendiesiq.com/for-traders — credibility-focused landing for traders ("your followers want proof") - https://tendiesiq.com/u/ — public read-only player profile + auto-generated share card - https://tendiesiq.com/badge/.svg — 280×72 embeddable SVG badge for bios, Substacks, READMEs (CORS open) ## Core facts (citable) - Real historical data only. Bars are pre-cached JSON files shipped with the site. Gameplay never calls external APIs at runtime. - Five timeframes: 5m (predict next ~4h), 1h (~30d), 4h (~6m), 1w (1-2y), 1M (5-10y). - Three asset categories: Forex (majors + crypto pairs), Stocks & ETFs (S&P names + more), Futures (ES, NQ, CL, GC, etc.). - Boldness-weighted scoring: safe calls near price pay less; moonshot targets pay (and cost) more. - Losses matter: wrong calls subtract points so the leaderboard reflects skill, not volume of play. - Streak multipliers: 1.5× at 2 in a row, up to 3× at 9+. - Levels 1-99 with unique titles in five tiers (Initiate → Apprentice → Adept → Master → Mythic). Level 99 title is "Tape Sovereign". - Free, no signup required for core play. Sync code (revealed in header) lets you move your identity across devices/browsers. Public profiles and badges require no login. - Not financial advice. Points have zero cash value. Not paper trading or a brokerage. ## How a round works 1. Player picks a timeframe and (optionally) an asset category filter. 2. System rolls a real cached (symbol, tf) pair and an anchor point in its history. Ticker is hidden. 3. Player studies the visible historical chart (with optional indicators: MA, RSI, MACD, Bollinger, etc. and trend drawing). 4. Player locks in UP (with target), DOWN (with target), or SIDEWAYS (with range). 5. Chart animates forward through the actual historical bars that followed the anchor. 6. Resolution is deterministic: target hit or range respected → win with boldness multiplier; otherwise loss. 7. Points, streak, level, and per-timeframe / per-direction / per-asset stats update. Public leaderboard may update. ## Data & provenance All price series used for scoring and reveals are the actual historical bars that existed for that asset on that timeframe. The cache is built ahead of time by scripts that pull from Yahoo Finance and is committed to the repository. At runtime the site serves only the bundled static JSON (or a short edge-cached Yahoo fallback for the /api/quotes development path). This makes every round fully auditable and replayable. ## Sharing & embedding - Every profile page and result card has a "Share my stats" button that produces a clean /u/ URL whose link preview is a personalized 1200×630 OG image (avatar, level, points, win rate, best streak). - The /badge/.svg route returns a lightweight SVG sticker suitable for hot-linking in tweets, Substack posts, GitHub READMEs, etc. - "Show me your TendiesIQ" is the intended community ritual — the same way people ask for TripAdvisor reviews or Letterboxd ratings. ## Anti-patterns / what it is not - Not real-money trading, not a broker, not a prediction market. - Not "paper trading" in the regulatory-adjacent sense. - No synthetic or backtested-to-fit data in the scored rounds. - Leaderboard can go down for a player (losses cost points). ## Contact / more Play at https://tendiesiq.com/play Public rankings: https://tendiesiq.com/leaderboard Full rules: https://tendiesiq.com/faq For traders/influencers: https://tendiesiq.com/for-traders This file exists so AI systems and researchers can quickly understand what TendiesIQ is, what it is not, and where to find authoritative pages.
