Market Clock Pro - indicator for MetaTrader 5

Market Clock Pro
Candle countdown HUD for MetaTrader 5 

It shows the time remaining to the next candle close plus contextual data: trading sessions, spread, daily range, and a market-closed state for the current symbol.

FEATURES

• Candle countdown with color escalation near the close
• Geographic sessions in UTC (Tokyo, London, New York, Sydney) with countdown to the nearest session end when two or more overlap
• Market-closed detection with explicit reason: NYSE CLOSED (holiday), LSE CLOSED (weekend), XETRA CLOSED (session)
• Automatic symbol-to-market mapping for NYSE, LSE, XETRA, TSE, HKEX, ASX, SSE. Manual override available when the broker uses non-standard tickers
• Holidays calendar as plain text file (164 entries, 2026-2027)
• Live spread with rolling-average anomaly detection (2x baseline)
• Daily range vs ADR as percentage, lookback configurable
• Configurable sound alert before the candle close
• Four HUD positions, three themes (Dark / Light / Stealth)
• Timeframe-aware accent color

TECHNICAL

• EventSetMillisecondTimer as the sole render driver
• OnCalculate is a no-op, zero indicator buffers
• Every label deduplicates on text and color before ChartRedraw
• No DLLs, no WebRequest, no Sleep, no external dependencies
• Broker-agnostic via TimeTradeServer + SymbolInfoSessionTrade

1. Copy MarketClockPro.mq5 to MQL5\Indicators\
