About Alpha Quant Terminal
Alpha Quant Terminal v9.2.3 —
The Execution Terminal for Prediction Markets
Stop guessing your stake size. Alpha Quant Terminal is a hyper-fast quantitative execution tool built specifically for Polymarket. Every feature exists to answer one question: how much capital do I deploy on this edge?
Paste a Polymarket URL, set true probability against market price, and get exact Kelly Criterion stake recommendations across four aggression levels — or switch to flat bankroll % sizing for fixed-stake plays. Log trades in one click, sync across devices with a passphrase, track whale wallets, and analyze your edge over time.

WHY USE IT
Most prediction-market traders size positions by feel. AQT replaces "feel" with mathematics. Two sizing engines, in-place sport detection, automatic Polymarket integration, and per-sport version tagging let you measure which models actually work and which don't.
━━━━━━━━━━━━━━━━━━━━━━━━━
CORE FEATURES
▸ Fractional Kelly Engine — Input price + true probability, get exact stakes for Full / Half / Quarter / Eighth Kelly fractions
▸ BANK % Flat Sizing Mode — Skip Kelly entirely with a 5th tile for flat bankroll % sizing (0.5%–100%). Always-visible gradient slider escalates color from gold → amber → orange → red as you increase exposure. Quick-pick buttons for 1–5%
▸ Polymarket Integration — Floating "α Add to AQT" button on every market page captures URL, title, and team images in one click
▸ Cloud Sync — Push and pull your full portfolio across devices using a private passphrase. No account, no signup
▸ Multi-Profile — 3 independent portfolios with separate bankrolls, plus an ALL view that merges them
▸ Sport + Version Tagging — Per-sport version memory with autocomplete dropdown. Tag every trade by model version to measure which iterations actually work
▸ Live Score Fetch — One-click "RESULT" button pulls live scores from ESPN's public API for NHL, NBA, MLB, NFL, ATP/WTA, and major football leagues
▸ Whale Watcher — Track up to 20 Polymarket wallets. Real-time trade feed with smart fill aggregation, threshold-based alerts, and per-wallet filtering
▸ Shareable Cards — Canvas-rendered PNL cards for individual trades and a complete season performance card. PNG export for Twitter/Discord
▸ Shadow Bets — Paper-trade any position without touching your bankroll. Dedicated tab with separate win-rate tracking
▸ Advanced Analytics — Equity curve, calendar heatmap, win-rate trend, cumulative PnL by sport, profit by day-of-week, risk/reward ratio, longest streaks, monthly breakdowns
▸ Side Panel + Fullscreen Modes — Lock the terminal alongside Polymarket, or open as a full tab for analysis sessions
▸ CSV Export & Import — Full data control per profile, including BANK% actual vs intent columns for execution drift analysis
▸ 6 Themes — Midnight, Ocean Blue, Stealth Black, Forest Green, Cyber Yellow, Coffee Brown

PRIVACY
This extension does not collect or track personal data. All trade data is saved to your local browser storage. Cloud Sync uses Firebase Realtime Database — data is encrypted in transit via HTTPS and accessible only with your private passphrase. Whale Watcher uses Polymarket's public Data API to read on-chain trade history of wallets you choose to track — no authentication, no private keys, no wallet connection required. No accounts, no third-party analytics, no ads.
What changed and why:
Hero pitch in 2 paragraphs. New users get the value prop in 30 seconds before scrolling.
"Why use it" section — answers the implicit question every reader has ("why this vs the dozen other Kelly calculators on Github?"). The differentiator is BANK %, sport tagging, and Polymarket integration.
Core features as a flat list with checkmarks. Easier to scan than version-grouped sections. New user doesn't care whether something shipped in v9.0 or v9.2 — they just want to know if AQT does X.
BANK % is item #2 in core features. It's the newest differentiator and shouldn't be hidden in a "what's new" section.
"How to start" section — addresses installation friction. Most extensions skip this and lose first-time users at the "what do I do now" moment.
Changelog moved to bottom and condensed. Returning users can still see what ch…
