Starting July 1, 2025, the company will discontinue support for outdated versions of both trading platforms and strongly urges clients to upgrade their terminals to ensure uninterrupted access.

According to the announcement, the minimum supported versions will be MetaTrader 4 build 1440 (released on February 21, 2025) and MetaTrader 5 build 4755 (released on December 13, 2024). Terminals running earlier builds will no longer be able to connect to OnFin’s servers after the deadline.

Action required: immediate terminal upgrade recommended

OnFin strongly advises all traders to verify and update their MetaTrader terminals as soon as possible to avoid service disruptions. The current version can be checked by selecting “Help / About program” in the terminal menu.

If the version is outdated, traders should download the latest software version from their personal cabinet on the OnFin website. The updated version can be installed directly over the existing one, making the upgrade process quick and straightforward.

Ensuring seamless trading and platform security

This technical update aligns with OnFin’s ongoing commitment to maintaining platform security, performance, and stability. By supporting only the most current MetaTrader builds, the broker ensures access to enhanced features, bug fixes, and more reliable order execution—all of which are essential in today’s competitive trading environment.

MetaTrader 4 and MetaTrader 5 remain among the most widely used trading platforms globally, appreciated for their advanced features, customizable tools, and support for algorithmic trading. Keeping platforms updated is crucial for both optimal performance and cybersecurity.

Final reminder

OnFin reminds all users to complete the upgrade before July 1, 2025, to avoid potential service interruptions. The broker’s support team is available to assist with the upgrade process and resolve any technical issues.

With this step, OnFin continues to prioritize client satisfaction and infrastructure modernization, reinforcing its position as a trusted partner in the fast-evolving global trading landscape.

As a reminder, since May 13, OnFin clients have also gained access to a curated selection of Argentinian stocks listed on the NYSE and NASDAQ, expanding the platform’s global equity offering.
