​

0.3.42

​

New Features

• SMT Divergence — new Smart Money Technique indicator. Compares fractals and session levels of two correlated assets (e.g. BTC vs ETH). Two modes: fractal (Williams fractal 3/5) and level (PDH/PDL/PWH/PWL sweep detection). Reference symbol search, configurable lines/dots/styles, second asset price overlay.
• Server notifications — banner with important messages from administration (updates, maintenance).
• Server watchdog — health monitoring script for data servers with auto-restart.

​

Workspaces

• Instant switching — no reload, direct config swap + connector reconnect.
• Theme applies correctly on workspace switch.
• Heatmap slider preserved in workspace config.
• “New workspace” creates with default config.
• Delete confirmation — custom modal before deletion.
• Dialog layout — wider (720px), balanced columns, shortened labels.

​

Alerts

• Global dedup — 5 second window between identical indicator alerts.
• once_per_bar fixed — disables after fire, re-enables on new candle.
• Cluster alerts — dedup by candleTime+price (not just price).

​

Server

• WS broadcast optimization — removed redundant String clones.

​

0.3.38

​

New Features

• Ruler Tool — measure distance between two chart points: bars, time, price, change%, volume, delta, bid/ask. Middle-click activation. Configurable rows, colors, font size, line style.
• Mean Reversion Channel — Ehlers SuperSmoother indicator with 6 filter types, inner/outer bands, gradient zones.
• OB Depth Overlay: Gradient Mode — smooth continuous fill showing orderbook depth dominance with border lines.
• Diamond Alert Markers — redesigned “brilliant-cut gem” geometry with crown, pavilion, facets, highlights, and Double Diamond halo.
• DrawSidebar — permanent drawing tools panel docked to left edge of chart.
• Resizable Subcharts — drag dividers to resize subchart indicator panels; height and order persist in tab config.
• Appearance Drawer — slide-in panel for chart appearance settings (replaces dropdown popup).
• Workspace Dialog in Header — folder icon in global header; export/import config to/from JSON.
• App Version in Header — current version displayed in window header.
• Double-Click to Live — double-click chart to scroll to latest candle + auto-fit Y axis.

​

Drawing Tools

• Head & Shoulders — reworked to 7 points (Start→LS→Valley(L)→Head→Valley(R)→RS→End) with LS/Head/RS labels and full neck line.
• XABCD — auto-finish at 5 points with anchor circles and smart label placement.
• Elliott Wave — auto-finish at 6 points (0→1→2→3→4→5) with standard wave labels.
• Early Finish Protection — double-click/right-click won’t finish H&S, XABCD, Elliott, Quasimodo until required point count is reached.

​

DOM (Depth of Market)

• Bar Style — 3D (rounded, gradient, shadows) or Flat (minimalist rectangles).
• Adaptive Grouping — tick steps auto-calculated from symbol’s real tickSize (1x, 5x, 10x, 25x, etc.).
• Seamless Tiling — DOM bars render from price-halfStep to price+halfStep, eliminating gaps at any zoom.

​

Widget Tab

• Compact Header — symbol search button + indicators button with active count on one row.

​

Bug Fixes

• 1000-prefix symbols (PEPE/BONK/SHIB/FLOKI) — fixed dead overlay on symbol switch via surface.rendered subscription; server symbol converter restores “1000” prefix.
• Candle fetch race condition — scope-key instead of requestSeqRef; data arriving after symbol/interval change is correctly ignored.
• CVD Divergence minDistance — added i-p > minDist check between divergence endpoints; lastAnyIdx prevents bull/bear signal clustering.
• Anchored CVD first load — delta fallback changed to undefined (not price delta); falls back to vb-vs from klines.
• Alerts — trigger only on crossing, not on first render; fixed crash on tab.alerts = undefined.
• tickSize — fallback on error instead of exception; binancef checked first; precision preserved for small prices.
• Auto-retry — dataCache retries 2x on network/timeout errors.
• Candle↔Heatmap switch — scroll state preserved.

​

Server

• Forming candle — inline OHLCV aggregation without JSON clone/merge/sort.
• WS throttle — separate throttle: candles 100ms, volumes 300ms; separate TF lists.
• Feed — on_trade without tokio::spawn overhead.

​

UI/UX

• All hardcoded border-white/5 → border-[var(—border)].
• Light themes: improved borders and contrast.
• Full i18n for IndicatorsOverlay (~200 new localization keys).
• Anomaly highlighting removed from all subchart indicators (code and settings UI).

​

0.3.24

​

Bug Fixes

• DPI scaling fix — chart no longer detaches from axes on any display scaling (125%, 150%, 200%, 250%). Crosshair markers now display correctly on all DPI settings. Tested across 100–250% scaling range.
• Chart rendering under axis labels — fixed chart content extending behind price/time axis labels on high-DPI screens.

​

Improvements

• Remote diagnostics — automatic error/warning collection sent to server for faster issue resolution. No personal data collected.
• DevTools in release builds — F12 now opens developer console in release builds for on-site debugging.
• Telemetry improvements — fixed device fingerprint collisions, improved system info accuracy.

---

​

0.3.18

​

Improvements

• Light theme contrast — significantly improved contrast and readability across all 3 light themes (Light, Moderate Light, Solarized Light). Borders, text, inputs, and indicator colors rebalanced for visibility.
• Telemetry diagnostics — automatic collection of system info (GPU, DPI, screen, OS) sent to server once per day. Helps diagnose rendering issues like chart detachment from axes.
• Bug report enrichment — the bug report button now copies full system info to clipboard before opening the feedback form.

​

Bug Fixes

• Double crosshair markers — eliminated duplicate price/time axis markers caused by SciChart native labels rendering alongside custom DOM markers.
• Crosshair marker clipping — fixed orange price marker being cut off by overflow container.
• Crosshair marker size instability — marker no longer changes width as cursor moves. Fixed with tabular-nums font rendering and consistent precision formatting.
• Y-axis too wide — reduced unnecessary padding on price axis labels for a tighter layout.
• Indicator pills invisible in light themes — replaced hardcoded text-emerald-200 with CSS variable colors.
• Hardcoded white borders/text — replaced border-white/* and text-white/* across 8+ components with theme-aware CSS variables.
• Logo invisible in light themes — added brightness filter for startup screen logo.

---

​

0.3.16

​

Improvements

• Native screenshots — screenshots now use Windows API (BitBlt), capturing the entire window pixel-perfect — all charts, indicators, heatmap, toolbar. File is saved to downloads + copied to clipboard.

​

Bug Fixes

• Screenshots work correctly — fixed issue where screenshots only captured canvas/SVG elements without HTML content (empty panels, missing labels, watermarks).

---

​

0.3.14

​

Improvements

• HD Heatmap — doubled heatmap resolution (~$10.5 price step for BTC instead of ~$21). Order book depth visualization is now significantly more detailed.
• Heatmap stability — eliminated “checkerboard” artifacts where heatmap blocks jumped between snapshots. Price granularity and range are now cached and stabilized.
• Server switcher — quick server selector in the header bar. Switch between Finland (FIN1) and Russia (RU1) data servers on the fly, or enter a custom server URL.
• TPO settings localization — all TPO (Market Profile) settings are now fully translated in Russian locale.
• Chart theme system — 160+ chart color themes including cryptocurrency-inspired (Bitcoin, Ethereum, Solana, BNB, XRP, Cardano, Dogecoin, Toncoin, Avalanche, Chainlink) and gaming-inspired (Valorant, GTA, Cyberpunk 2077) themes, each in dark and light variants.
• SciChart license — removed evaluation watermark from all charts.

​

Changes

• Indicator glow disabled by default — the premium glow effect on all indicators is now off by default. Enable it per indicator in settings if desired.
• History limit reduced — maximum history depth changed from 730 to 365 days for optimal performance.
• Enhanced Liquidations simplified — removed line and candle display modes; columns is the only display mode (most appropriate for liquidation data).

​

Removals

• Old Liquidations indicator removed — the legacy “Liquidations” indicator has been removed. Use Enhanced Liquidations instead, which provides richer visualization with buy/sell breakdown and volume scaling.

​

Bug Fixes

• Minor tick marks removed — eliminated barely-visible tick marks from all chart axes for a cleaner look.

---

​

0.3.6

​

Bug Fixes

• Cluster data flickering — eliminated candle data flickering/jumping caused by REST and WS data fighting. Removed WS Open correction and cluster H/L expansion ratchet that caused one-way drift.
• 2x volume in forming candle — fixed double-counting where raw trade volumes were added on top of REST volume profile during the first ~10 seconds after load.
• Trade counts — corrected trade counting to match industry standard (1 per aggTrade). Previously used individual fill decomposition which inflated numbers vs other platforms (TigerX, ATAS, ExoCharts).
• Heatmap stability — added referential stability check to prevent unnecessary full data replacements on periodic refetches.

---

​

0.3.0

​

New Indicators

• OB Depth Overlay — colored bands behind candles showing bid/ask dominance at 5 orderbook depth levels (0-1%, 1-2.5%, 2.5-5%, 5-10%, 10-25%). Dominance formula: (bids - asks) / (bids + asks). Configurable thresholds, opacity, and per-band colors.
• Diamond Alerts — Spot + Perpetual orderbook confluence detection. Detects reversal points when both markets show bid or ask dominance simultaneously. Single and Double Diamond types with sound alerts and visual markers on chart.

​

Bug Fixes

• Net Longs/Shorts — fixed bars showing ~10 per candle instead of 1. Now uses candle-close bucketing (last heatmap snapshot per candle).
• CVD Divergence — fixed O(n²) performance issue causing slowdowns on large datasets.
• Delta Divergence — improved calculation accuracy.
• Orderflows Divergence — fixed detection logic.
• VWAP — corrected session reset behavior.
• Liquidation Levels — rendering improvements.
• Market Structure — improved swing point detection.

​

Server

• Heatmap collector for spot + futures orderbooks (15s snapshots).
• New API routes: funding rate, heatmap data, metrics.
• Import scheduler improvements and blob codec optimizations.
• Orderbook cache performance improvements.

​

UI

• DOM on Chart overlay — expanded functionality.
• Persistent cache improvements for faster data loading.
