Visualizing Open and Historical Trades with MQL5 Chart Objects
Summary
This practical MQL5 tutorial describes an Expert Advisor that uses chart objects to display trade information. Trend lines connect a position's entry with the current price, rectangles show the trade area toward stop loss or take profit, and text labels report prices and current profit or loss. The EA is also designed to reflect changes to a position's stop or target and to adjust the chart display as a trade continues.
A second part of the project uses historical deal data within a chosen date range to draw past trade paths and annotate outcomes. The article discusses looping through open positions and historical deals, creating and modifying objects, and using inputs to configure the display. Its evidence consists of implementation explanations and illustrative output, rather than a performance study. The tutorial teaches chart-based monitoring and review; it does not establish that the visualizations improve trade decisions or returns.
Key ideas
- Trend lines can display movement between a trade's entry and current price.
- Rectangles and labels can show stop or target areas, prices, and current profit or loss.
- Chart objects can be updated as position parameters and market prices change.
- Historical deal records can be used to draw past trades and annotate their outcomes.
- The project demonstrates visualization and data handling, not improved trading performance.
