Senzoukria v0.8.4 release notes

Nobody wrote reviewed notes for this version. What follows is the release body as published on GitHub, unedited.

• VWAP mean reversion bands
• Four standard-deviation bands around VWAP — ±1σ, ±2σ, ±3σ, ±4σ, each one switchable with its own multiplier. Off by default: an update never repaints a chart you didn't ask it to. Bands 1 and 2 are pre-armed behind the master switch, so one click gives you the standard picture without eight lines landing on your footprint at once.
• Every band is labeled with its price, not just its multiple (+2σ 28034.25). A mean-reversion level you have to hover to read is a level you can't place an order against.
• Two ways to measure σ, and the panel says which is which. Typical price takes one sample per bar at (H+L+C)/3 — the figure your other screens show. Footprint levels takes one per price actually traded, which is the real dispersion, and will not match other platforms. Both are correct; the difference is explained in the settings panel rather than left for you to discover by comparison.
• σ is now computed with Welford's method. The textbook formula (E[x²] − E[x]²) subtracts two nearly equal numbers at index-level prices, and was losing about five significant digits before rounding. The bands are accurate at MNQ/ES price magnitudes now.
• Big Trades appear while the candle is still forming
• Bubbles no longer wait for the bar to close. On the candle view, Big Trades bubbles stayed frozen for the entire duration of the bar, then all appeared at once on close — up to a 60-second lag on a 1-minute chart, five minutes on M5.
• The window buffer memoises a cursor so panning through history doesn't rescan the whole ring. That cursor only reset when its time bound moved forward — true for the heatmap, which passes a clock, but false for the footprint, which passes the right edge of the forming candle: a bound that sits in the future and doesn't move until the bar closes. Everything ingested in between ended up above the cursor and was never drawn.
• Fixed by rescanning only what arrived since the previous frame. The panning optimisation is preserved, and both behaviours are now pinned by tests.
• Broker catalog
• Astrofund is listed, with its dxFeed rail marked coming soon rather than offered. The firm issues its own dxFeed credentials to funded traders and has no Rithmic accounts to hand out — so giving it a Rithmic option would have produced an entry that fails on every single connection attempt. It's documented without being promised.
• Windows build only. macOS and Linux builds are not included in this release; the previous beta builds remain available from earlier tags.
