Changelog

Every release and what changed in it. The app updates itself, so you are on the newest one unless you dismissed the prompt.

0.2.5

14 August 2026

The 0.2.4 build was tagged but never published, so everything in it is included here. This is the first update since 0.2.3.

Connect your own broker

  • Sign in with tastytrade or Coinbase using your broker’s own login. There are no API keys to create, copy or store: the app never sees a key, and your session lives in the operating system keychain.
  • tastytrade brings the first live futures execution path in macrodesk, with the front month resolved for you, so MES becomes the correct quarterly contract without you looking it up.
  • A Rithmic connector for prop and funded accounts, with its own card in the broker picker.
  • The account bar reads from the connected broker, so net liquidity, cash and buying power are the broker’s numbers rather than the simulator’s, and the header says plainly which one you are on.

Live data on the entitlement you already pay for

  • Charts and the watchlist stream from your connected broker’s feed, so a connected account gets live data at no extra cost. The source ladder runs Rithmic, then your broker, then Databento, and falls back to delayed data when none is connected.
  • Switching or disconnecting a broker now re-routes the feed immediately. Previously the chart kept the source it started with until you changed symbol.
  • Deeper crypto history, and a 72 hour seed window for tastytrade crypto symbols.

Order flow

  • Depth heat behind the candles for crypto, drawn from a continuously recorded order book, with the recorded history browsable in the overlay.
  • Footprint mode: bid and ask volume at every price, in place of candles.
  • Absorption bubbles on the tape, with large prints labelled by notional value.
  • The depth ladder is a full scrollable price grid. Every tick has a row, you can click any level to trade, and working orders appear as pills on their own row.

Trading from the chart

  • Order lines carry a pill whose size and order type are each clickable, so you can resize an order or switch between limit and stop without opening anything.
  • Right click a resting order to set an exact price and size.
  • Take profit and stop loss lines show what they would realise if they filled.
  • The depth ladder reads profit and loss in the units you think in, whether dollars, points or ticks, and it shows what a partial exit has already banked instead of only what is still open.
  • A bar close countdown sits under the last price on the axis.

A gate before a mistake reaches your broker

  • Pre-trade risk limits catch a slipped digit before an order leaves the app: a maximum order size, a maximum position size, and a price band that rejects an order priced far away from the market.
  • Limits are in contracts for futures, and in shares and dollars for stocks and crypto.
  • An order that reduces an existing position is never blocked. A risk control must not be the reason you cannot get out.

Paper trading

  • Commission is charged on simulated fills, so a paper edge is one a funded account could repeat. It can be switched off.
  • Trailing stops, post only and immediate or cancel.
  • Resting paper orders can keep filling while the app is closed, if you opt in.
  • A durable store for the trade journal, with layered backups of your configuration and accounts.

News and the calendar

  • Headlines are tagged by market and theme, so news reaches the instrument it concerns even when it never names it. Company news follows the charted stock and appears as dots on the chart.
  • The news panel and the economic calendar scope themselves to what you are looking at.

Learning the app

  • Every panel introduces itself the first time you open it, and a guided tour walks the real interface rather than a video.
  • Bar replay gained real playback speeds, a clock, keyboard control, step intervals and a visible cut at the replay point.

Speed and battery

  • Idle processor use is roughly half what it was. The largest single cause was two crypto order book recorders that ran on every installation, including ones that never opened a crypto chart. They now follow you: chart any crypto pair once and they return.
  • The chart no longer re-renders when nothing on it has moved, panels load when first opened rather than at startup, and the panels that track the tape now redraw once per frame instead of once per price change.
  • The chart itself was ported to a new rendering engine.

Fixes worth naming

  • Order and bracket lines follow the price scale itself, so they track the chart while you drag it instead of jumping when you let go.
  • The last price tag is clipped at the edge of the chart rather than drawn over the toolbar.
  • Dragging the chart no longer selects text.
  • A double click on the depth ladder rests one order, not two.
  • Bid and ask lines are labelled, and collapse into one when the spread is a single tick.

0.2.4

18 July 2026

Tagged but never published. Its changes shipped inside 0.2.5.

Paper ledger

  • A date column on the paper positions ledger, labelling each day so a run of shuffled times reads clearly.

0.2.3

18 July 2026

Positions and performance

  • The positions panel takes the whole main area as a full page, instead of squeezing beside the chart.
  • A trading statistics dashboard on that page: win rate, profit factor, average win against average loss, and daily results.
  • On a wide screen the charts pair side by side rather than stacking.

Depth ladder

  • The extended ladder: a full virtualised price grid that follows the market, with a recenter control when you have scrolled away.

Under the hood

  • Data source state machines, pointer-capture dragging, and two security fixes from an external review.

0.2.2

17 July 2026

Account tracker

  • Expandable rows showing how long a position has been held, on a real opened-at foundation rather than a guess.
  • An expanded row collapses back to the symbol, and the detail strip animates rather than snapping.

0.2.1

14 July 2026

The release where broker trading became free, and the chart learned deep history.

Pricing

  • Brokerage access moved to the free plan. The AI Desk and the local model runner are free on every tier too, using your own key.

History and the chart

  • Daily, weekly and monthly charts on native deep history, with a parallel fetch and a disk cache so the second visit is instant.
  • Progressive loading paints a short range immediately and extends behind it, with a spinner during a cold fetch rather than an empty axis.
  • A latest-updates card behind the event dots, and event pins scoped to the instrument you are charting.
  • A twelve hour clock option for the time axis and crosshair.

Safety

  • A reinstall-proof configuration backup and an accounts recovery net, so a fresh install does not start from nothing.

Speed

  • The custom indicator engine moved to the platform’s own JavaScript engine, which made scripted indicators dramatically faster.
  • The War Room map was split out of the startup bundle, and order line repaints were separated into two cadences so panning stays smooth.

0.1 series

June and July 2026

Twenty builds that established the app: the chart, the simulator, the desk and the map.

What was built

  • A frameless desktop window with its own title bar, a categorised interval picker with favourites and custom intervals, and volume profile as a chart indicator, including the visible range variant.
  • The paper trading simulator with its balance ledger, bar replay with isolated practice fills, and chart click orders that also work during replay.
  • The broker facade that later carried live accounts, with a guard that forces replay orders to paper.
  • The AI Desk: local model discovery, hardware-aware fit scoring with realistic speed estimates, and download progress.
  • The news feed with a thirty day local archive, free text ticker lookup, keyboard navigation in symbol search, and the War Room with looping radar and a global natural events layer.
