Interactive Stop-Loss and Take-Profit Lines for Market Replay

Summary

This installment describes a MetaTrader 5 interface for selecting and editing position price levels in a market replay or simulation tool. It uses a highlighted horizontal line and nearby controls to make a level easier to select when several lines are close together. The controls can move focus between take-profit and stop-loss levels, remove a level, and create a price line when one is absent. Chart events connect the interface actions to position-management messages.

The implementation is presented as an indicator component that can be reused beyond an Expert Advisor. The article focuses on user interaction and object management rather than a trading signal or execution strategy. Its code shows one approach built around chart objects, mouse events, and custom messages, but the excerpt provides no usability measurements or evidence that the interface improves trading outcomes. It is part of a larger replay-system series, and the author notes that the component will need further adaptation for pending orders.

Key ideas

• A dedicated move control can make closely spaced price levels easier to select.
• The interface represents levels with chart objects and updates their positions when the chart changes.
• Custom chart events connect clicks with actions such as focusing, moving, or removing a level.
• The described component is intended for a market replay and position-management interface, not for generating trading signals.
• Adapting the class for pending orders is left for later work.
