Tick Analyser, Volume Underlay, Bar Statistics heatmap and alerts that snap to profile levels
Rolled out on 22 and 23 June. A panel that narrates the tape in plain language, volume bars under price, nine new Bar Statistics rows with a heatmap style, value-area fading for footprints, and Volume Profile upgrades including alerts placed exactly on POC, VAH and VAL.
New
- Tick Analyser panel (Add Widget, Market Overview). Plain-English commentary on every print for one instrument: a headline, strength, side, tags and an explanation, with All and Strong filters, above an Aggressor Balance session summary. Tick Analyser guide.
- Volume Underlay indicator draws volume bars under price in the main chart with up and down colours, opacity, height, bar width and an optional moving average. Bars are pixel-snapped so they tile evenly at every zoom.
- Fade Outside Value Area for footprints, with an Outside Opacity setting that dims cluster cells outside the value area.
- Bar Statistics rows and heatmap. New rows for Buy %, price change and change %, bar range, relative volume with a period, average trade size, session volume, delta divergence and OI build-up (long build-up, short build-up, short covering, long unwinding). Cells can render as bars or a heatmap normalised per day or per visible range, with auto-contrast text, last-bar highlight, row separators and session totals in the legend. Bar Statistics guide.
- Alerts snap to Volume Profile levels. Right-click near a profile to add an alert at the exact POC, VAH or VAL under the cursor, or at the raw cursor price.
- Volume Profile upgrades: a bid × ask split mode that is stacked or mirrored, optional Auction Market Theory badges and Initial Balance per anchored group, price labels that honour the instrument's tick size, and only the forming candle re-binned on each tick.
- Open scanner symbols in linked panels. Clicking a Power Scanner row loads the symbol into the panels linked to the scanner, or a new chart if none is linked.
Improved
- Fixed Range Volume Profile matches the footprint. Bins use the same price-based bin height and edge rule as cluster cells so totals line up, the value area is a contiguous band expanding from the POC, and labels respect the show-as-lots setting.
- Indicator panes can be dragged to reorder, and each pane's price axis formats values to suit the indicator.
- Footprint Summary rewritten with a value-area band, column cells, POC highlight and headers in the same heatmap and auto-contrast language as VWAP and Bar Statistics; the live candle refreshes on every tick.
- VWAP moves to a monochrome blue band scheme where lines fade outward and fills are darkest at VWAP; Anchored VWAP matches.
Fixed
- Charts focus the latest data correctly on symbol, timeframe and session changes: no stale re-bucketing on a timeframe change (the cause of mis-scaling), no one-frame snap, a width-aware fit, mode switches that render in place without refetching, and live ticks that preserve your viewport.
- Footprint Summary no longer bloats workspace saves. Its render caches are excluded from cloud and local saves, which had failed or grown to several megabytes.
Performance
- Hidden chart tabs park their render loop instead of waking 60 times a second.
- Indicator calculations are cached: one computed series per indicator is shared between readings, last value, colour and rendering, where previously it was recomputed up to five times per render and on every crosshair move.
- Workspace chrome no longer re-renders on connection status, latency or log updates, and panels restore through a deterministic queue.
