Visualizing Binomial Distributions with Interactive 3D Graphs in MQL5
Summary
The article describes extending an MQL5 binomial distribution viewer with a DirectX-rendered 3D mode. Histogram bars show simulated frequencies, while a projected theoretical probability mass function (PMF) helps compare observed samples with expected probabilities. Users can switch between 2D and 3D views and rotate or zoom the camera, with automatic camera fitting available. A ground plane, colored axes, and existing statistics, legends, and themes provide context for reading the display.
The implementation organizes rendering and interaction in a visualizer class, with configurable camera, ground, and axis settings. The article reports that automatic fitting makes the bars visible and that switching modes preserves data and layout. It presents a visualization tool rather than a trading strategy or evidence that 3D views improve decisions. The examples concern binomial distributions, and the article notes that further work is planned for panning and additional distributions.
Key ideas
- The tool compares simulated binomial frequencies with a theoretical probability mass function.
- A DirectX scene renders the histogram bars, ground plane, axes, and projected PMF curve.
- Users can switch between 2D and 3D modes and adjust the 3D camera by rotating and zooming.
- Camera fitting and display settings are configurable, while existing statistics and legends remain available.
- The article describes implementation and visual inspection, not trading performance or predictive evidence.
