PairPlot: Visualizing Relationships Between Trading Time Series
Summary
This article presents PairPlot, a graphical tool for examining relationships among multiple trading time series. It arranges a histogram for each series and scatter plots for each pair in a cross-table layout, with trend lines as visual aids. The design uses reusable chart components built around MetaTrader 5’s graphics library, including classes for scatter plots, histograms, and the overall display. The histogram component can also construct a vertical, Market Profile-style view.
The tool is intended to help traders inspect distributions and identify possible correlations among instruments, including as an initial step in searching for arbitrage ideas. The article explains the component structure and provides a demonstration indicator, but the supplied excerpt does not report statistical tests, out-of-sample evidence, or trading results. Visual correlation alone does not establish a stable relationship or profitable strategy, and the author notes that the tool is only an aid to early analysis rather than a complete trading system.
Key ideas
- PairPlot displays per-series histograms and pairwise scatter plots in a cross-table layout.
- Trend lines provide a visual reference when comparing two time series.
- Reusable chart classes support variable numbers of instruments and different plot types.
- The tool is intended to support exploratory correlation analysis and arbitrage research.
- Visual patterns require further analysis and do not by themselves validate a trading strategy.
