Designing an Interactive Chart Trading Panel in MQL5
Summary
This article examines the core class behind an interactive Chart Trade panel for MetaTrader 5. The panel is built as a floating chart embedded in an indicator, with editable regions, mouse-position checks, and a template that stores layout and display settings. The class updates displayed values such as leverage and financial take-profit and stop-loss amounts, applies the template, and redraws the chart. The author notes that the code could also be adapted for an Expert Advisor, with changes.
The article explains the interface structure and selected initialization and state-management logic, but omits the message-dispatch procedure that handles user actions to open or close market positions. That interaction logic is reserved for a follow-up article, so this installment is not a complete guide to order handling. It provides implementation detail for building and configuring a chart-based trading interface, but offers no evidence about trading performance or risk controls beyond the panel’s displayed financial values.
Key ideas
- A floating chart can host a configurable trade interface within an indicator.
- Store panel dimensions, positions, colors, and fonts in a template for reuse.
- Check mouse coordinates against interface regions to identify the selected control.
- The omitted message-dispatch procedure handles interactions that open or close positions.
- The panel’s interface code can be adapted for an Expert Advisor with changes.
