Named sessions, TPO letters, and a full order ticket

What you can do now that you could not before.

• Market Profile now anchors on named sessions — Asia, London, New York — each drawn in its own colour with its own levels, instead of one profile spanning the whole day. This is the gap every other platform in the category leaves open.

• Added TPO letters to the Market Profile, in the canonical Sierra Chart form. Volume Profile now uses the real CME trading day (Globex open to open) instead of a calendar day, and its row resolution adapts to zoom — a "Resolution" setting lets you pin it, or leave it on auto.

• Big Trades bubbles were rebuilt: they are now real objects on the chart that pan and zoom with it, the way DeepChart's do, instead of markers pinned to fixed screen positions. The size threshold now slides automatically with recent volume, and a burst filter and auto-filter strength are configurable from the panel.

• Heatmap: a new colour ramp for the liquidity gradient — the ask side is now a magenta that stays distinguishable for the most common form of colour blindness, where the previous red/amber pair did not. Added a "Low" floor so faint liquidity stays visible instead of washing out, hover now shows the real lot count at a level (not an estimate), and detected icebergs are drawn as overlays on the book. Settings moved from a popover — which had outgrown its own space — into a tabbed dialog.

• The trading panel is now a complete order ticket: four order buttons (limit and market, both sides), risk:reward shown in dollars and as a ratio, position size computed from the risk you're willing to take, and a P&L readout you can click to cycle between dollars, ticks and percent. Position management gained reverse, close partial, and move stop to breakeven. Risk distance to your stop is now shown in ticks at your current order size.

• The quantity you set in the trading panel, the quick-trade bar, and the chart's right-click menu is now the same number everywhere — it used to be three independent values. The right-click menu itself grew: stop-here and target-here (reading the side from your open position), flatten, and cancel-all-orders, alongside the existing limit orders — deliberately no market orders in that menu.

• Option Flow gained a second data source: Tradier, real-time on the free Lite brokerage account — no 16-minute delay on trade prints, which the existing Alpaca free tier imposes. Switch between the two from the Option Flow header if you already have a Tradier token saved for GEX; nothing new to set up.

• Added 3 more prop firm accounts to the broker connection catalogue (Earn2Trade, Tradeify, Elite Trader Funding — Evaluation), sourced from Rithmic's own current gateway list.

• Connecting to Rithmic now offers the 13 official points of presence, defaulting to Chicago — previously only one gateway per environment was reachable. The choice doesn't apply to the Test environment, where it has no meaning.

• 49 chart indicators that plot a line or histogram (out of 204) gained an optional smoothing setting. Off by default — nothing already on your chart changes unless you turn it on.

• Indicators now have a clear answer to "what's actually on this chart right now" across built-ins, the 204-indicator catalogue, and your own scripts — a foundation for a legend, which is not on-screen yet.

• The Scripting assistant can now search and read the web — arXiv, SSRN, exchange documentation — when it's helping you write or debug an indicator or strategy. This runs entirely on Anthropic's servers, not from anything installed on your machine; the sandbox your scripts run in is unaffected and stays exactly as closed as before (no network, no files, no Tauri API). The other five assistants in the app are unchanged.

The symptom, written the way you saw it on screen.

• Fixed charts sometimes showing no data at all until you pressed F5. A failed market-data subscription was being recorded as successful, so the app never retried; it now retries on a short backoff and, separately, re-subscribes automatically if no data arrives within 8 seconds of a subscription the server called successful.

• Fixed dragging a selected drawing tool's handle sometimes moving your position's entry line instead — the entry line was checked before the tool's own handles, regardless of what was actually selected.

• Fixed the Scripting page's layout stretching far past the screen instead of scrolling. A flex row was measuring itself against its unwrapped content before wrapping — over 4500px of it — rather than the space actually available.

• Rithmic order notifications: added a guard against a subtle protocol pitfall. Two distinct message types share most of their internal field numbers, so decoding one as the other can succeed silently instead of erroring — this is now checked and logged rather than trusted.

Speed, ergonomics — what would surprise you if you knew the previous version.

• Windows MSI and installer.

• Python scripting is built and tested but not released in this version — the language button says so. JavaScript scripting is unaffected.
