FxSocket Python SDK

Typed Python client for the FxSocket API. Connect your MetaTrader 4 / 5 accounts, then place trades, read market data, and stream live updates over REST and WebSocket — with mirrored synchronous and async interfaces.

Features

• Account management — link, list, fetch, and disconnect MT4/MT5 accounts.
• Trading — market & pending orders, modify, close, plus margin/profit calculators.
• Market data — quotes, symbol specifications, OHLC history, account state & info.
• Live streaming — ticks, bars, account, positions, trades, and terminal status over WebSocket, with automatic reconnect + subscription replay.
• Sync and async — Client / AsyncClient, method-for-method mirrors.
• Typed — Pydantic v2 models throughout; ships py.typed.
• One interface for MT4 and MT5 — platform differences handled for you.

Install

pip install fxsocket

Requires Python 3.10+.

Quickstart

from fxsocket import Client

with Client(api_key="fxs_live_…") as fx:        # or set FXSOCKET_API_KEY
    account = fx.accounts.list()[0]
    term = fx.terminal(account)

    print("equity:", term.account_summary().equity)
    print("EURUSD:", term.quote("EURUSD").ask)

Authentication

Every call uses your FxSocket API key (fxs_live_…), from the dashboard. Pass it explicitly, or set the FXSOCKET_API_KEY environment variable and call Client() with no arguments.

from fxsocket import Client

with Client(api_key="fxs_live_…") as fx:
    for account in fx.accounts.list():
        print(account.platform, account.nickname, account.status)

Managing accounts

from fxsocket import Client

with Client(api_key="fxs_live_…") as fx:
    # Link a new account (platform defaults to MT5).
    account = fx.accounts.create(
        platform="mt5", server="ICMarkets-Demo", login=1150125, password="…",
    )

    # Poll until it's connected.
    account = fx.accounts.get(account.id)
    print(account.status)                  # connecting → connected

    # Where this account's terminal API lives (empty until provisioned).
    print(account.rest_url, account.ws_url)

    fx.accounts.delete(account.id)         # unlink

Everything is also available on AsyncClient:

from fxsocket import AsyncClient

async with AsyncClient(api_key="fxs_live_…") as fx:
    accounts = await fx.accounts.list()

Trading & market data

fx.terminal(account) returns a REST client bound to that account's terminal (resolved from account.rest_url, whether it's a shared pod or a private droplet):

from fxsocket import Client

with Client(api_key="fxs_live_…") as fx:
    account = fx.accounts.get("…")         # must be connected (has a terminal)
    term = fx.terminal(account)

    summary = term.account_summary()       # balance, equity, margin, …
    quote = term.quote("EURUSD")           # latest tick
    bars = term.price_history("EURUSD", "M5")   # recent OHLC bars

    result = term.order_send(              # market buy
        symbol="EURUSD", operation="Buy", volume=0.10,
        stop_loss=1.07, take_profit=1.10,
    )
    if result.success:
        term.order_modify(result.order, take_profit=1.12)   # None keeps the SL
        term.order_close(result.order)

Every order call returns an OrderResult. A 200 only means the terminal answered — check the body: success is true for retcode 10009 (done) or 10008 (placed), and outcome classifies the result as applied / no_change / partial / rejected (compare against OrderOutcome).

no_change (retcode 10025) is a benign, idempotent no-op — the requested SL/TP/price already match — so it's safe to treat as applied even though success is False. For idempotent SL/TP management (e.g. re-sending after a lost confirmation), send absolute values and gate on result.is_effective (true for both applied and no_change):

res = term.order_modify(ticket, stop_loss=1.0850)
if res.is_effective:        # applied now, or already in effect
    ...

Inputs are validated client-side before they're sent. One guard worth knowing: in order_modify, a literal stop_loss=0.0 would remove your stop-loss, so it's rejected — pass clear_stop_loss=True to remove one deliberately, while None (the default) keeps the current value.

MT4 and MT5 share one interface. MT5-only timeframes (M2, M3, H2, H6, H8, H12) raise UnsupportedOnPlatformError on MT4 before any request.

MT4 history note: on MT4, price_history with from_/to bounds (or the D1 timeframe) can fail server-side with CopyRates failed when the terminal hasn't loaded that history. Calling price_history(symbol, timeframe) without date bounds returns the most recent bars reliably.

Streaming (WebSocket)

Subscribe to live ticks, bars, account, positions, trades, and terminal status. Streaming is async-first; a synchronous wrapper is provided too. A dropped connection auto-reconnects and replays active subscriptions (auto_reconnect=True by default).

import asyncio
from fxsocket import AsyncClient, Tick, Bar, AccountUpdate

async def main():
    async with AsyncClient(api_key="fxs_live_…") as fx:
        account = await fx.accounts.get("…")
        async with fx.stream(account) as s:
            await s.subscribe_prices("EURUSD")
            await s.subscribe_bars("EURUSD", "M5")
            await s.subscribe_account()
            async for event in s:
                match event:
                    case Tick():
                        print(event.symbol, event.data.bid, event.data.ask)
                    case Bar():
                        print(event.symbol, event.timeframe, event.data.close)
                    case AccountUpdate():
                        print("equity", event.data.equity)

asyncio.run(main())

Synchronous equivalent:

from fxsocket import Client, Tick

with Client(api_key="fxs_live_…") as fx:
    with fx.stream(fx.accounts.get("…")) as s:
        s.subscribe_prices("EURUSD")
        for event in s:
            if isinstance(event, Tick):
                print(event.data.bid, event.data.ask)

Errors

Every failure raises a subclass of fxsocket.FxSocketError:

from fxsocket import Client, AccountCapError

try:
    fx.accounts.create(server="Demo", login=1, password="…")
except AccountCapError as e:
    print(f"Plan limit reached: {e.current}/{e.cap}")

Private hosting

Privately-hosted accounts (a dedicated droplet) are listed, traded, and streamed exactly like shared-cluster accounts — their rest_url / ws_url simply point at the droplet. The droplet serves a self-signed certificate, so reach it with Client(..., verify_terminal_tls=False) (or supply a pinned CA). Creating a private-hosted account is done in the dashboard.

Timestamps

Terminal timestamps (quote.time, candle time, order times) are returned as strings in broker server time — not Python datetime. The trailing Z is stylistic and does not mean UTC. Use terminal.server_timezone() to get the broker's UTC offset if you need to convert.
