OANDA Japan will discontinue its MetaTrader 4 (MT4) and MetaTrader 5 (MT5) web terminal services at the end of May, removing browser-based access for traders. The broker confirmed that both MT4 and MT5 web terminal services will stop at the end of the month, as it continues a broader transition away from MT4.
Following the discontinuation of the web terminals, OANDA Japan is directing clients to use the desktop versions of MT4 or MT5 or to trade via mobile applications on iOS and Android. The company has advised that chart settings created on the web platform will not transfer to other versions, although key trading data such as account balances, open positions, and pending orders will remain intact after the web terminal closes.
Transition Away from MT4
The end of the web terminals is part of a phased withdrawal from MT4 by OANDA Japan. The broker has already stopped opening new MT4 accounts and has outlined a timetable for the full retirement of the platform. It plans to halt order placement on MT4 in September, before completely shutting down trading and login access in November.
OANDA Japan cited cybersecurity requirements and the lack of ongoing maintenance for MT4 as key reasons behind the transition. According to the broker, MetaQuotes has stopped maintaining the legacy platform, prompting a reassessment of its continued use in light of security and operational considerations.
Changes to Trading Conditions
In April, OANDA Japan tightened trading conditions on MT4, raising margin requirements to a flat 10%. This change effectively reduced leverage to 10:1, which is significantly below Japan’s regulatory cap of 25:1. The adjustment preceded the announced timeline for ending order placement and ultimately closing MT4 trading and login access later in the year.
The combination of higher margin requirements, the suspension of new MT4 account openings, and the scheduled shutdown of web and desktop access underscores a comprehensive shift in OANDA Japan’s platform offering. Clients are expected to migrate to alternative platforms, including the desktop and mobile versions of MT4 and MT5, ahead of the final cutoff dates.
