A new TPO engine with a volume profile beside every column, and a terminal-wide performance pass
Rolled out between 9 and 11 June. Stacked Market Profile gets its own horizontal scale and an info box per profile, the Option Chain drops from two hundred live connections to one, and crosshair movement no longer repaints the whole chart.
New
- New TPO engine. Stacked TPO mode has a native horizontal scale: panning is a one-to-one pixel offset, zoom scales column widths, and the crosshair and time axis read the real column layout, which ends the pan, zoom and crosshair drift. Hover a profile for a TPO Profile Info Box with session date, POC, VAH and VAL, session high, low and range and TPO count. TPO settings guide.
- Volume profile beside each TPO column. A volume-at-price histogram with its own settings: position, metric (volume, delta or bid × ask), Histogram, Linear or Step style, width, opacity, bin size, gradient, POC, VAH and VAL lines with style and colour, HVN and LVN with counts and colours, naked POC only, inside and outside value-area colours and label format. Extended lines carry their start-date label.
Improved
- Mobile tab strip. Panel tabs scroll horizontally on phones and a scroll drag no longer activates the tab under your finger.
- Touch controls in settings and the colour picker respond properly, and ghost clicks after a tap are swallowed.
- Drawing settings start collapsed so a selected drawing does not cover the chart.
Fixed
- Blank chart after restoring a workspace. Charts in hidden tabs are kept mounted with a safe minimum size, so restoring a workspace no longer leaves an empty chart.
- Duplicate layers in the Layer Manager: one layer per indicator or drawing, and the race that created two is closed.
Performance
- Crosshair movement no longer re-renders the whole chart. Pointer state lives in a small interaction store with tiny overlay components for the OHLC readout and replay selection.
- Drawings render on their own canvas between the base and interaction layers, so dragging or selecting a drawing never repaints the footprint or TPO beneath it.
- Option Chain: two hundred connections become one. Per-symbol subscriptions are replaced by a single feed and rows re-render only when their own tick arrives.
- Workspaces restore in parallel, idle panels skip drawing, the footer clock no longer re-renders the workspace every second and change detection pauses while the tab is in the background.
