MQL4 Color Scales, Gradients, and Heatmaps for Market Watch Symbols

Summary

The document introduces an MQL4 display tool for showing daily percentage changes across symbols in a Market Watch list. It describes three visual modes—scale, gradient, and heatmap—and says the example uses RGB colors with the standard string-to-color conversion function. The stated aim is to make relative asset moves easier to scan visually; the document does not explain the color mapping rules or provide performance evidence.

The author recommends using the display with at least five symbols and no more than roughly twenty to twenty-five, so the information can fit on screen. This is a presentation aid rather than a trading signal or a tested strategy. The text gives no guidance on interpreting colors, choosing thresholds, handling missing data, or comparing assets with different characteristics, so users would need to inspect the implementation and decide how to use the display in their own workflow.
