FxSocket

FxSocket is a cloud hosting API service for MT4 and MT5 aimed at developers, providing a REST API and WebSocket interface. It helps developers run MetaTrader terminals in the cloud without needing their own VPS, local installation, or writing MQL code, enabling them to execute trades, read market data, and manage accounts through Python, Go, JavaScript, or any other language that supports HTTP. The service provides real-time bid and ask price streaming, order updates, historical candlestick data (OHLC, including tick volume and spread per bar), and account and trade history queries. On security, it supports full-permission trading keys and read-only keys, with end-to-end encrypted connections, and FxSocket does not touch user funds; funds are held by the broker to which the user connects. It is suitable for scenarios such as automated trading strategy deployment, cross-account copy mirroring, backtesting data retrieval, custom trading interface development, and risk control rule programming. Pricing offers shared and dedicated plans; specific prices and the number of included accounts must be checked on the official website purchase page.

About this tool

FxSocket is a trading API platform aimed at developers, allowing users to operate MT4 and MT5 accounts through code rather than the MetaTrader terminal interface. Its core idea is to run the MetaTrader terminal in the cloud, so users only need to connect their own broker account to execute trades, obtain market data, and perform account management through the REST API or WebSocket.

Purpose

FxSocket is mainly aimed at developers who want to trade forex, stocks, commodities, and futures programmatically. It replaces the traditional approach that requires a local VPS, Windows server, or writing MQL code, allowing developers to interact directly with MT4/MT5 using the language they are familiar with (such as Python, JavaScript, Go, Rust, Java, C#, or any language that supports HTTP).

Main capabilities

  • Cloud-hosted terminals: FxSocket runs MetaTrader terminals in the cloud, so users do not need their own VPS or local installation, and the terminals remain online and connected.
  • REST API: Provides simple, predictable endpoints for account management, order execution, and trade history queries, returning clean JSON on each call.
  • WebSocket streaming: Real-time push of bid/ask quotes, order updates, and tick data, with sub-millisecond latency.
  • Security mechanisms: Supports full-permission trading keys, and can also generate read-only keys limited to specific accounts; connections are encrypted end to end.
  • Language agnostic: Say goodbye to MQL, and choose Python, JavaScript, Go, Rust, Java, C#, etc.; input and output are pure JSON. Official Python and Node.js SDKs are provided.
  • Historical data: Pull candlestick history (OHLC bars, including tick volume and the spread of each bar) through a single endpoint, which can be used for backtesting; real-time ticks can also be streamed via WebSocket.
  • Platform support: Supports cloud-hosted MT4 and MT5 terminals. MT5 supports multi-asset trading such as forex, stocks, commodities, and futures, as well as netting and hedging modes.

How to use

According to the official description, "you can be up and running in 3 minutes." The basic process is:

  1. Add a broker account: enter the broker credentials, and FxSocket will start a cloud-hosted MetaTrader for the user. terminal, without a VPS, installation, or maintenance.
  2. Get an API key: generate a key in the dashboard, choosing either a full-permission trading key or a read-only key limited to selected accounts.
  3. Use REST or WebSocket: execute trades in any language, stream data, and automate.

Use cases

  • 24/7 strategy operation: deploy automated trading strategies, connect Python or Node.js bots, and no need to stare at the terminal.
  • Cross-account mirror trading: build a copy-trading platform, detect trades in the master account via WebSocket, and instantly copy them to follower accounts via the REST API.
  • Pre-trade testing: pull years of candlestick data (including the spread on each bar) through a single endpoint and feed it into a backtesting engine, with no screen scraping, CSV downloads, or MQL.
  • Custom trading interfaces: build dashboards and mobile apps on top of FxSocket to get real-time P&L, position management, and account monitoring.
  • Risk-control automation: programmatically set drawdown limits to automatically close positions, set maximum lot sizes, or pause trading when volatility spikes.
  • Scale trading infrastructure: manage hundreds of funded accounts from a single integration, provision terminals on demand, monitor trader performance, and enforce firm-level risk policies.
