Check out the new article: Win Rate and Edge Ratio Heatmap by Hour and Symbol in MQL5.
This MQL5 dashboard aggregates closed deals by symbol and UTC hour, calculates win rate and average reward‑to‑risk, and displays the results as two color‑coded heatmaps. A companion table in the Experts tab highlights the strongest and weakest symbol/hour cells, with an option to require a minimum trade count to reduce noise.
Running one strategy across several symbols and hours effectively creates many distinct strategy variants. Traders often do not realize this. EURUSD at the London open behaves nothing like XAUUSD overnight, and a single blended win rate across the whole account can hide the fact that some symbol-and-hour combinations are quietly profitable while others are quietly bleeding money. There is no built-in way to see this two-dimensional pattern; the terminal's history view is a flat list, not a grid.
The script groups closed deals by symbol and UTC closing hour. For each symbol–hour cell, it computes win rate and edge ratio (payoff ratio). It then renders two CCanvas heatmaps: one for win rate and one for edge ratio, shaded from red through amber to green. An Experts tab table lists the best and worst symbol-and-hour combinations by win rate, so the pattern is available as both a picture and a plain list.
