What is Currency Heatmap?
Currency Heatmap displays the relative strength of selected currencies in a color-coded matrix on MT4. Horizontal and vertical currency lists create a pairwise view, while timeframes provide additional comparison rows.
Green, red, and gray states separate stronger, weaker, and unchanged readings in the display. The package includes an .ex4 file and the matrix is intended as market context rather than a standalone instruction.
How to use Currency Heatmap
Review the currency matrix across the selected timeframes, then compare the displayed state with the related price charts. The heatmap makes relative strength differences visible without opening each pair separately.
CurrenciesHorizontal, CurrenciesVertical, and TimeFrames define the matrix. StrongUp, WeakUp, NoMove, WeakDown, StrongDown, and DoesNotExist set the displayed colors, while UseMSLineDrawFont controls the font option.
Where it helps
The matrix organizes relative strength in one chart panel.
Timeframe rows provide additional context for the displayed states.
The configured colors separate stronger, weaker, and unchanged readings.
