Exotic pairs have wildly variable spreads depending on the session and market conditions. Instead of guessing when liquidity is good, let's automate it. In this guide, you'll build a custom MT5 indicator that tracks real-time spread, plots a rolling average, and color-codes the chart background green/yellow/red.Indicator StructureThe core logic uses SymbolInfoInteger and SymbolInfoDouble to fetch SYMBOLSPREAD on every tick. Store the last N spread values in a ring buffer, calculate the rolling mean and standard deviation, and classify: green (spread 2σ). Draw rectangles on the chart background.MQL5 Skeletonint OnCalculate(...) { double spread = SymbolInfoDouble(Symbol, SYMBOLSPREAD); ArrayFill(spreadBuffer, 0, 1, spread); double...
