MetaTrader 4 is a software platform for manual and automatic trading, including free clients (end-user terminals) for Windows, iPhone, and Android, as well as server-side modules for processing trade transactions, storing and distributing history of quotes, proxy-servers, and administration tools (for brokers).

MetaTrader 4 is a widespread online trading platform designed to provide brokerage services to customers in FOREX Majors, Metals, Commodities, CFD, Indices, Futures and recently even BTC cryptocurrency markets.

The MetaTrader Terminal 4 natively supports a built-in programming language MQL4 and other DLL #import-s, which together allows users to extend the standard functionality with custom scripts, expert advisers (trading robots) and technical indicators.

MetaTrader server-side functionality is also extensible with their proprietary MetaTrader 4 API.

MetaQuotes head of sales, Anthony Papaevagorou, has announced that MetaQuotes no longer intends to issue upgrades to the MetaTrader 4 (MT4) [reported on 2016-11-15]
