Creating a Persistent, Interactive Chart Trade Panel for Market Replay

Summary

This installment develops the interface layer of an MQL5 Chart Trade panel designed to work across live, demo, and replay environments. The panel uses a chart object as its visual surface and adds editable fields for leverage, take-profit and stop settings, along with window controls. Event handling routes chart interactions to the panel class, while template data preserves editable values and appearance across timeframe changes, when MetaTrader removes and reloads indicators.

The article explains error reporting, editing and validation of user-entered values, and saving panel state when a chart change occurs. A demonstration video shows the interface behavior, but the implementation still does not execute buy, sell, or close-position actions. The focus is modular interface and state management for a future trading tool, not order execution or strategy performance. The author notes that the code is presented in the article without downloadable attachments and expects readers to follow the larger series to understand its dependencies.

Key ideas

• The panel uses an embedded chart object as the basis for an interactive trading interface.
• Editable parameters and display state are stored so they can survive timeframe changes.
• Chart events are dispatched to a class that handles interface interactions and input validation.
• The version described does not yet place or close trades.
• The code is part of a larger replay-system series and relies on earlier components.
