Cross-Asset Close Colorizer highlights candles whenever the main symbol and a reference symbol close in opposite directions (chart up-close & reference down-close, or vice versa), making cross-asset divergence instantly visible; you can choose the reference symbol and timeframe, set custom colors for both cases, and optionally color only the candle body (keeping default wicks/borders). Dojis remain neutral by design, the reference series is requested with lookahead_off to avoid repainting, and two constant alert conditions are included (“Chart UP & Ref DOWN” and “Chart DOWN & Ref UP”). Ideal for pairs like EURUSD↔GBPUSD, ES↔NQ, or BTC↔ETH—attach the indicator to your main market and select the reference (optionally on a different timeframe).
