Price-axis controls, pinned timeframes, compact legends and charts that remember their history
Chart workflow controls arrive on the price axis and in the interval menu, composite volume profiles can cover fixed ranges, and downloaded history is kept in the browser so reopened charts load from the last cached day.
New
- Price-axis quick controls. Right-click the main price axis to toggle auto-fit, switch between linear and log, reset the price scale without resetting time, or open Scales & lines settings. Indicator-pane axes get reset and settings menus, and a double-click resets them.
- Compact indicator legends show the hovered or latest candle's values inline, up to three readings with an overflow tooltip, compact units for large volume and delta, and a settings button to show or hide parameters and values.
- Pinned timeframe shortcuts. Star intervals in the interval dropdown to choose which appear as toolbar shortcuts, pin custom intervals, and use Reset pins to restore the defaults. Pins are saved per account.
- Composite volume profile ranges. The composite profile can aggregate the previous day, the current or previous week, the current or previous month, or the last N trading days instead of only the visible profiles. Two-sided profiles get a Left or Right position in the indicator, the Fixed Range drawing and TPO mode.
- OHLC history is kept in the browser. Downloaded bars are stored per series in memory and in IndexedDB, so reopened charts and page reloads refetch only from the last cached trading day. History also arrives as compressed binary frames, cutting download size.
Improved
- Only the dragged drawing repaints while you move it, and Market Profile now renders inside the main chart pipeline.
Fixed
- Scrolling back through history no longer skips a day. The older page ended a day early because the server excludes the end instant; pages now end exactly at the loaded start.
- Theme switches repaint the chart even when the market is closed, instead of keeping the old colours until the next tick.
Performance
- Chart workers start on demand: an unused footprint worker was removed, tick workers start only when tick history is first parsed, and the drawings canvas is released when idle.
- Off-screen volume profile bars are skipped and the per-frame sort runs only for Linear and Step styles.
- Panels opening together share one history request per time window and one tick request per session instead of each fetching its own copy.
- Broker orders and positions are written to storage once per poll and only when something changed.
