MetaTrader 5 Build 5800 Redesigns the Main Trading Dialog

MetaQuotes has shipped MetaTrader 5 Build 5800, and the most visible change is a redesign of the platform’s main trading dialog. The update adds a built-in Depth of Market view inside the order window, moves order-type switching into a side panel, and places one-click trading enable and disable controls directly inside that workflow instead of leaving them buried in platform settings.

For traders who live inside MT5 all day, that is more than cosmetic. The trading dialog is where position size, order type, entry method, and speed all come together. MetaQuotes said this release is only the first stage of a broader redesign, with later updates expected to expand stop-level placement and risk-management controls.

Build 5800 also updates the built-in help system to a web-based engine, fixes balance drawdown calculations in trading reports, improves proxy-setting handling, expands CUDA support for ONNX models, and adds a table view for CSV files in MetaEditor. That last part is more relevant to strategy developers than discretionary traders, but it still points to ongoing investment in the MT5 ecosystem.

Why it matters

MT5 remains one of the most widely used retail trading platforms across forex, CFDs, and listed derivatives. Changes to the order-entry workflow can affect execution speed, usability, and risk controls for millions of traders using broker-branded MT5 installs.

What to watch next

The key question is whether brokers roll the build out quickly and whether the next redesign stages materially improve stop placement and risk controls. Traders should also check for any broker-side lag before assuming every MT5 login is already running the new version.
