A tour of the app

Five minutes here saves you hunting later. The app is one sidebar, one topbar, and the engine command strip. Everything else hangs off those three.

The sidebar

Once your plan is active, pages are grouped by what they're for:

• TRADE: the daily drivers. Overview is your start screen: the three setup steps (choose your plan, connect your broker, choose your leader account), each with a link to the page that does it and a tick once it's done, then your Weekly Review card and a row of links to help, contact and the legal pages. Trade Desk holds open positions with their P&L, per-position close, cancelling working orders, the order history, and a read-only Rules panel for each copy group.
• TRADE SETTINGS: things you configure, then mostly leave alone. Accounts (broker connections and their discovered accounts), Copy Rules (groups, followers, sizing; each group links back to its place on the Trade Desk), and Risk Management (the live risk monitor, daily loss limits, profit targets, locks, order expiry, the optional confirmations, and quick switches for e-mail and Telegram alerts).
• RESOURCES: analysis, not controls. Journal, with seven sub-pages: Dashboard, Weekly Review, Trades, Daily, Weekly, Strategy, and Manage Data. Then Economic Calendar and Educators & Creators. This section starts open. Click the RESOURCES heading to fold it away on a trading day, and click it again to bring it back. The app remembers which way you left it.
• At the bottom, under a thin rule: Affiliate and Settings. A small plan chip under them names your plan and says how many accounts it covers; click it to manage your plan.

Until your plan is active, the sidebar holds only Overview, and its first step is where you choose a plan. Everything above appears the moment the plan is active, including your own copier: every account runs its own, and nothing another customer does can stop or flatten yours.

Two things fold: Journal starts folded (click it to show or hide its seven sub-pages) and RESOURCES starts open. A chevron points right when something is folded shut and down when it is open. If you open a page that lives inside a folded section, the section opens itself so you can always see where you are. On a narrower screen, roughly tablet width, the sidebar shrinks to a strip of icons by itself (hover any icon for its name), with every section shown.

The topbar

Left to right:

• Engine pill shows your copier's state from any page: Stopped, Starting, Copying, Reconnecting, Stopping, or Error, in the engine strip's colours: green while copying, amber while the kill switch is armed after Flatten all (it still reads Copying), and amber Stopped when something other than your own Stop ended the session (the broker signed the login out, or MirrorFill support stopped your copier).
• Open-positions chip appears whenever anything is open, on every page except the Trade Desk (which lists every position): a count plus up to three contract symbols, for example 2 OPEN · ESZ6, MESZ6, so a forgotten position is visible from every page on a wider screen. A phone's top bar drops it.
• Market clock: Chicago time and the CME Globex equity session in plain words, HH:MM CT · CME open or HH:MM CT · CME closed. Globex opens Sunday 17:00 CT, closes Friday 16:00 CT, and halts for maintenance 16:00-17:00 CT Monday through Thursday. When it says CME closed, no fill is coming.
• Alerts bell keeps recent connection events (a drop, a reconnect, a login signed in elsewhere), Flatten all, rejected orders and errors. Fills and risk alerts never reach the bell: risk alerts arrive as toasts, and fills do too if you switch fill toasts on in Settings → Notifications.
• Theme toggle: a quick light/dark flip (in the avatar menu on a phone). The three-way choice (system, light, dark) lives in Settings under Appearance.
• Your avatar menu: your account, Settings, Help center (these articles, in a new tab), and Sign out. The help center is also under Settings → About → Support.

The engine pill, the open-positions chip and the alerts bell belong to your copier, so they appear once your plan is active; before that there is no copier for them to report on.

Pages without a headline of their own, like Settings or the Journal pages, show their name at the top of the page.

The engine command strip

The engine command strip sits at the top of every trading page: Trade Desk, Accounts, Copy Rules, and Risk Management. It shows the copier's state and only the button that applies right now: Start copying while stopped, Stop while copying (with Resume copying beside it after Flatten all), then Flatten all after a divider. On a phone the Desk and Rules tabs carry the full strip, Risk keeps Flatten all (plus Resume copying while copying is paused), and Accounts has none. Details in engine controls explained.

The Trade Desk

Under the engine strip, the Positions heading carries the open count (for example 3 OPEN) and the leader (LEADER · APEX-104 · ES), then View rules, the List | Cards switch and, while copying runs, Pause all and a red Cancel orders. When every follower is paused, Pause all reads Resume all, and then it shows even while the copier is stopped. The leader is set on Copy Rules; the desk shows it but has no control to change it. The gear at the end holds the desk settings: whether follower protection is on, Hide account numbers, + Contract to add a contract filter, and the table's column list (not on a phone).

While copying runs, a row of contract chips filters the positions whenever there is more than one contract to choose between, or a chip you added with + Contract. It works the same in List, in Cards and on a phone, and a filter you set keeps its chip until you clear it, so rows never vanish without a reason on screen. Below the chips, one band totals Day P&L, Open P&L, balance, open positions and the last event.

Positions are grouped by copy group. Each group's strip names the group, its leader and how many followers it has, folds on a click (a fold hides the followers, never the leader), and carries Rules for the read-only rules panel. Followers holding a position come first, then by name. Every row holding a position ends in a red Close; in Cards view it sits at the bottom of the card, and a phone has none. While the copier is stopped the board lists no positions and says "The copier is stopped. Start copying to see positions here." Before anything is set up, it shows the one step that is missing instead, with a button for it (such as Add connection). At the bottom of the page, Order history is one collapsed line with today's fill count, plus today's rejects and failures in red; open it for the All, Fills, Copies, Rejected and Failed tabs, search and reload. It remembers whether you left it open.

On your phone

Below 720px wide, the sidebar becomes a slide-out drawer (the menu button at the top left opens it) and a bottom tab bar carries the primary pages: Desk, Accounts, Rules and Risk, then More, which opens the drawer with every other page, Overview and the Journal included. The drawer also shows the market clock at its top. The top bar keeps the MirrorFill logo, the engine pill, the alerts bell and your avatar menu; the theme switch and the help center are in the avatar menu. It's the same app. The few things a phone leaves out, such as the per-position Close and the open-positions chip, are named where they come up.

Until your plan is active the tab bar reads just Overview and More, with no engine pill or bell in the top bar, and the Overview page ends with links to the help center, the FAQ, contact and the legal pages (plus Manage cookies where the cookie banner is in use). Settings and the other pages are not open yet, so that row is where those links live; it stays on Overview afterwards too.
