Changelog
What's new in 0xInsider.
New features, improvements, and fixes — shipped weekly.
Live P&L for Open Positions
Open positions now show unrealized profit/loss based on live order book prices. See at a glance whether a trader's current bets are winning or losing.
NewAnalyticsPortfolioRefined Terminal Color Palette
The trading terminal now uses a unified color system with improved contrast and readability. Grade colors, trade sizes, signal scores, and all data cells use a cohesive dark-mode palette designed for extended screen time. Borders, backgrounds, and hover states are more subtle and consistent across every panel.
ImprovedTerminalCalibration Edge Column in Terminal
A new Edge column in the terminal shows whether a whale systematically finds underpriced contracts or overpays. Unlike raw win rate, edge accounts for entry price — a 60% WR at 50-cent entries is +10% edge, while 85% WR at 90-cent entries is -5% edge. Green means the trader wins more often than their prices imply, red means they overpay. Win rate colors now also match the tooltip ranges.
NewTerminalDaily, Weekly & Monthly Analytics Reports
Recurring analytics reports now live at /reports. Daily, weekly, and monthly reports show active traders, whale trade volume, the biggest trades ranked by size, hottest categories, and grade distribution. Filter between cadences with a single click. Each trade links directly to its detail page.
NewAnalyticsContentSign In with Google

NewPlatformBeta Countdown Timer

NewPlatformImproved Filter Chip Readability
Inactive filter chips in the terminal (size, side, and grade) now have higher contrast text for better readability. Lighthouse accessibility score: 100/100.
FixedTerminalSearch Any Polymarket Trader
Search now reaches beyond 0xInsider's database. Type any Polymarket username or wallet address and we'll find them — even if they've never been tracked before. Click an external result to import the trader instantly. You'll see a syncing banner while we pull their full history, then the profile loads automatically with complete stats, grades, and P&L.
NewPlatformInstall 0xInsider as an App
0xInsider can now be installed to your home screen on mobile and desktop. Tap "Add to Home Screen" in your browser menu to launch it as a standalone app — no browser chrome, full-screen terminal experience. Works on iOS, Android, Chrome, and Edge.
NewPlatformColorful Filter Bar & Grade Filter
New grade filter in the terminal filter bar — toggle S, A, B, C, D, or F to see only trades from traders at that level. Multi-select any combination. Size chips now match the feed’s color coding: $10K+ white, $25K+ blue, $50K+ orange, $100K+ purple. Buy/Sell chips glow green and pink. Every filter chip shows its signature color at a glance. Grade filter is Insider only.
NewTerminalTerminal Column Redesign & Grade Improvements
Redesigned the terminal feed layout for better scannability. Trader name and grade are now fused into a single column — the colored letter after each name tells you the grade at a glance. Signal score colors now match the tooltip legend (slate → blue → amber → orange → red). Every trader with stats now gets a grade — no more gaps. Losing traders get D or F, profitable traders get at least C. Backfilled 1,376 previously unranked traders and added an automatic hourly sweep so no trader goes without a grade.
ImprovedTerminalGradingSmarter Trader Classification
Trader type labels now factor in actual performance — not just behavioral patterns. Profiles that showed strategy-like trading patterns but had no real edge (negative alpha, low consistency, poor equity curves) are now reclassified as Speculators instead of receiving flattering labels like Algo Trader or Market Maker. 159 profiles updated.
ImprovedGradingAnalyticsSpread Column in the Terminal
The terminal now shows the top-of-book bid-ask spread for each whale trade, measured in basis points (bps). Formula: (ask − bid) ÷ midpoint × 10,000. It tells you how liquid a market is — a tight spread (under 25bps) means active price discovery with many competing orders. A wide spread (over 1000bps) means an illiquid orderbook where any sizeable order can shift the market. Five color-coded tiers from ultra-liquid to illiquid help you gauge signal quality at a glance. Lower spread = stronger signal. Works across Polymarket and Kalshi.
NewTerminalWhale AlertsPrice Range Filter for Whale Trades
Filter whale trades by market price from 1¢ to 99¢. Instantly spot contrarian bets on longshots under 25¢ or find conviction plays on heavy favorites above 75¢ — and everything in between.
NewTerminalWhale AlertsTerminal Filters Now Persist Across Sessions
Your terminal filter settings — platform, category, side, and price range — are now saved to local storage. Close the tab, come back later, and your filters are exactly where you left them.
ImprovedTerminalMentions Category in Market Classifier
The market classifier now detects Mentions-type markets (e.g. "Will Elon Musk mention Bitcoin?") and tags them correctly. Expanded crypto keyword detection across all categories.
NewAnalyticsPlatformInsider Avatar Ring in Sidebar
Insider subscribers now see a subtle ring around their avatar in the sidebar navigation. A small visual detail to distinguish your account status at a glance.
ImprovedPlatformPlatform Filter on Activity Feed
Filter your activity feed by platform — Polymarket, Kalshi, or Probable. See trades from one exchange at a time or combine them all.
NewTerminalF-Grade Support and Grade Badge in Profile Header
Trader profiles now show an F grade for underperforming wallets. The grade badge is now visible in the profile header alongside the trader’s name and stats.
NewGradingAnalyticsImproved Ranking Normalization
Refined the scoring algorithm to better normalize across volume tiers. Traders with thin history no longer get inflated scores from a single lucky trade.
ImprovedLeaderboardGradingResearch Section
Deep-dive research articles now live in their own /research section, separate from the learn hub. Case studies and analyses with full data breakdowns.
NewContentProfit Achievement Floor in Grading Algorithm
The grading algorithm now includes a profit achievement floor — preventing wallets with high Sharpe ratios but negligible absolute profit from receiving inflated grades.
ImprovedGradingUnified Grade Color Palette
Grade colors are now consistent across every chart, badge, and Tailwind class. S=violet, A=cyan, B=blue, C=amber, D=slate, F=red. Updated heatmap loss colors for better contrast.
ImprovedAnalyticsPlatformGeopolitics Separated from Politics
The market classifier now treats Geopolitics as its own category, separate from domestic Politics. Filter the leaderboard and analytics by either one independently.
ImprovedAnalyticsLeaderboardKalshi Tooltip Fixes
Corrected Time and Trader tooltips for Kalshi trades in the terminal. Anonymous traders now show a clear explanation of why identity data isn't available.
FixedTerminalChart Watermark and Email Image Improvements
Chart watermarks now render above axis labels for cleaner visuals. Fixed email digest images and improved 15-minute article data rendering.
