OANDA Securities, the Japanese unit of OANDA, will discontinue support for MetaTrader 4 later this year. The broker cited “cybersecurity requirements” and the platform’s “lack of ongoing maintenance” as the main reasons.

The decision follows earlier steps to scale back MT4 services. In 2024, the company shut down two MT4 servers and asked clients to “consider using MT5,” according to earlier reporting. The move reflects a broader industry shift as brokers gradually transition users to MetaTrader 5 while support for MT4 declines.

OANDA Sets November 2026 MT4 Shutdown

The Japanese unit of OANDA said MT4 services will end at the close of trading on November 27, 2026. The company linked the decision to a “tightening of cybersecurity standards” and “efforts to strengthen internal systems” to protect client assets and personal data.

The broker stated that MT4 “has been out for a long time” and is no longer covered by maintenance from MetaQuotes. It added that meeting “the latest security requirements” had become difficult under the current setup.

The phase-out process has already begun. Today (Firday), the firm suspended the creation of new MT4 sub-accounts on its Tokyo server. The next step is scheduled for September 25, 2026, when new order placement on MT4 will be halted after trading hours. Full termination will follow in November.

After the cutoff date, users will no longer be able to log in or execute trades on MT4.

OANDA Urges MT5 Migration Ahead Shutdown

The company said details on how remaining open positions will be handled will be provided at a later stage. Clients without open positions but with account balances have been asked to transfer funds to other account types, including MT5, fxTrade, or TradingView.

For customers using the MT4 New York server, trading will remain available through fxTrade or TradingView after MT4 is discontinued.

The company is encouraging clients to migrate to MT5 as soon as possible. It said the newer platform offers improved performance, including faster processing through 64-bit architecture, more chart timeframes, and enhanced backtesting capabilities.
