TickerAll Web Terminal

An MT5-style trading terminal that runs in the browser — chart any symbol and trade live against any MT4/MT5 broker through the TickerAll API, with no MetaTrader install.

It's a React app. The whole UI (charts, market watch, trade panel, drawing tools, alerts) is a shared renderer that reaches the outside world only through a single window.terminal platform object. This repo ships the web implementation of that object — talking to a backend over REST + WebSocket, with auth supplied by the host page. The backend is pluggable: it defaults to the TickerAll API, or you point it at your own (see Use with any API).

Status: early. The web target of the TickerAll terminal, extracted for public use. Charts, market data, and live trading run against the hosted TickerAll API out of the box.

Install

npm install @tickerall/web-terminal

The package ships prebuilt assets in dist/web/ (the bundle + index.html). Serve that folder as static files, or copy web.js + web.mjs + chunks/ into your app and embed them (see Embedding below).

Build from source

npm install
npm run build      # → dist/web/ (web.js, web.mjs, index.html, chunks/)
npm run typecheck  # tsc --noEmit

Run it

Open dist/web/index.html (served over HTTP, not file://). Sign in, connect a demo broker account (server / login / password), pick a symbol + timeframe, and the chart loads real history and streams live ticks. Broker passwords are only ever sent to the backend to open a session — they are never stored in the browser.

Embedding

The app reads its config from window.__TICKERALL_WEB__, set before web.js loads:

<script>
  window.__TICKERALL_WEB__ = {
    // REST + stream default to the public TickerAll API; override for self-hosting.
    baseUrl: 'https://api.tickerall.com',
    // Auth: the host supplies a short-lived session JWT (refreshed host-side).
    getToken: async () => currentSessionJwt,
    user: { id, email, displayName },
    tradingEnabled: true,
  };
</script>
<script src="web.js"></script>

Key config fields (all optional):

field	meaning
baseUrl / streamUrl	TickerAll API REST / WS base (default: the public API)
getToken	returns a valid short-lived session JWT — the embedded-auth path
authUrl	sign-in base URL for the standalone email-login path (no host token)
backend	a custom TerminalBackend to run against any API (see below)
tradingEnabled	false = watch-only (hides all buy/sell UI)
activeAccountId / activeSymbol / activeTimeframe	boot straight into an account / chart

If you host the terminal on a different API or a direct sign-in endpoint, widen the connect-src in the generated dist/web/index.html CSP (or supply your own CSP on the embedding page).

Use with any API

The terminal reaches all broker data, trading, and the live feed through one interface — TerminalBackend, defined in src/web/backend.ts. Implement it and inject it, and the UI runs against your server unchanged. Everything the backend returns is in the terminal's own types (PositionRow, ChartBar, Quote, …), so you map your wire format once, inside the backend — nothing TickerAll-specific leaks into the rest of the app.

1. Implement the backend

Only the core methods are required to make it work; the optional ones light up extra UI when present and degrade quietly when absent.

// implements TerminalBackend — see src/web/backend.ts for the exact signatures
export function createMyBackend(opts: { getToken: () => Promise<string> }): TerminalBackend {
  const api = makeClient(opts.getToken);   // your REST/WS client; sends the bearer token

  return {
    // ── Accounts (required) ──
    async listAccounts()        { return (await api.get('/accounts')).map(toBrokerAccount); },
    async connect(id)           { // fetch symbols + opening snapshot; THROW if the account is cold
                                  return toAccountConnection(await api.get(`/accounts/${id}`)); },
    async reconnect(id, pw)     { await api.post(`/accounts/${id}/connect`, { password: pw }); },
    async createSession(creds)  { return (await api.post('/sessions', creds)).accountId; },
    async disconnect(id)        { await api.post(`/accounts/${id}/disconnect`); },
    isNotHot(err)               { return (err as { code?: string })?.code === 'ACCOUNT_OFFLINE'; },

    // ── Market data (required) ──
    async candles(req)          { return (await api.get(candlesUrl(req))).map(toChartBar); },
    async symbolSpec(id, sym)   { return toSymbolSpec(await api.get(`/accounts/${id}/symbols/${sym}`)); },
    async positions(id)         { return (await api.get(`/accounts/${id}/positions`)).map(toPositionRow); },

    // ── Trading (required) — return { ok, message, ticket? } ──
    async placeOrder(req)           { return run(() => api.post(`/accounts/${req.accountId}/orders`, req)); },
    async closePosition(id, t, v)   { return run(() => api.del(`/accounts/${id}/positions/${t}`, { volume: v })); },
    async modifyPosition(id, t, sl, tp) { return run(() => api.patch(`/accounts/${id}/positions/${t}`, { sl, tp })); },

    // ── Live feed (required) ──
    openStream(h) {
      const ws = api.openSocket();
      ws.on('tick',      m => h.onTick({ accountId: m.id, symbol: m.sym, bid: m.bid, ask: m.ask, time: m.t }));
      ws.on('position',  m => h.onPosition(toPositionPush(m)));
      ws.on('orders',    m => h.onOrders({ accountId: m.id, orders: m.orders.map(toPendingRow) }));
      ws.on('account',   m => h.onAccount({ accountId: m.id, balance: m.balance, group: m.group ?? '' }));
      ws.on('reconnect', () => h.onReconnect());          // after a dropped socket re-establishes
      ws.on('state',     s => h.onState(s));              // 'connected' | 'reconnecting'
      return {
        subscribeTicks:     (id, syms) => ws.send({ sub: 'ticks', id, syms }),
        unsubscribeTicks:   (id, syms) => ws.send({ unsub: 'ticks', id, syms }),
        subscribeAccount:   id => ws.send({ sub: 'account', id }),
        subscribePositions: id => ws.send({ sub: 'positions', id }),
        subscribeOrders:    id => ws.send({ sub: 'orders', id }),
        close:              () => ws.close(),
      };
    },

    // ── Optional — add to light up the matching UI ──
    // history, ordersHistory, dealsHistory, listPendingOrders,
    // modifyPendingOrder, cancelPendingOrder, removeAccount, serverAlerts
  };
}

A cold account must make connect() throw an error your own isNotHot() recognizes — the terminal then prompts for the broker password, calls reconnect(), and retries connect(). Auth is separate from the backend: the host supplies the session token via getToken (above); the backend just uses it.

src/web/tickerallBackend.ts is a complete reference implementation (the default TickerAll backend) to copy from.

2. Inject it

<script>
  window.__TICKERALL_WEB__ = {
    getToken: async () => mySessionJwt,                     // your session bearer token
    backend:  createMyBackend({ getToken: () => getToken() }),
  };
</script>
<script src="web.js"></script>

For TickerAll, inject nothing — omit backend and the built-in createTickerallBackend talks to api.tickerall.com with your session token, no hooks required.

Layout

src/renderer/   the shared UI (charts, trade panels, drawing, alerts, themes)
src/web/        the browser platform — window.terminal, the TerminalBackend contract + default
src/shared/     the TerminalApi contract + settings schema
build.mjs       esbuild web build

src/web/backend.ts is the backend contract; src/web/tickerallBackend.ts is the default implementation; src/web/webTerminalApi.ts wires a backend into the renderer's window.terminal.
