Product changelog

v1.1 α 2026-04-24 · Live feel sprint

Chart rebuild + 4 new pages + live slippage + watchlist + alerts. 25 commits in one afternoon.

Charts

• FIXED OHLC continuity bug — each candle's open now equals the previous close. Zero gaps between bars.
• NEW lightweight-charts candlestick series on hero + terminal + equity curve
• NEW OHLC legend overlays with crosshair-driven hover values
• NEW Real volume histogram (was synthetic high-low proxy)
• NEW Moving-average overlays on terminal chart — MA 20, MA 50, Bollinger Bands (toggleable)
• NEW Cumulative depth chart under the order book (bids left, asks right)
• NEW 12-week commit activity heatmap on every repo page

Trading UX

• NEW Price flash 600ms animation — symbol bar + markets table row cells

Admin + status

Platform

• NEW Alpha signals get per-card 24h spark + 2σ/3σ/4σ severity colour
• NEW Leaderboard: per-trader 30d equity curve on podium + row
• FIXED Orderbook 500 on depth ≥ 10 — md5 seed pool was shorter than requested. Chained hash extends it.
• IMPROVED Consistent top nav across all pages (Markets · Trade · Compare · Activity · Portfolio · …)
