Trend and Sideways Detector

Trend and Sideways Detector

A powerful yet lightweight indicator designed to automatically detect market conditions — whether the market is in an Uptrend, Downtrend, or Sideways phase — using a refined Bollinger Bands-based algorithm.

This tool helps traders eliminate guesswork and trade with clarity, especially in fast-moving markets like XAUUSD on lower timeframes.

⚙️ Core Features

✅ Automatic Trend Detection

• Detects Uptrend when price breaks above the Upper Bollinger Band
• Detects Downtrend when price breaks below the Lower Bollinger Band
• Detects Sideways when price returns inside the Bollinger range

✅ Visual Market Zones (Color-Based)

• ? Uptrend Zone (Light Green)
• ? Downtrend Zone (Light Pink)
• ⚪ Sideways Zone (Gray)

✅ Integrated Bollinger Bands

• Middle Line (Trend Reference)
• Upper Band (Breakout Confirmation)
• Lower Band (Breakout Confirmation)

✅ Dynamic Trend Switching

• Trend state updates in real-time based on price interaction with Bollinger Bands
• Smooth transition between trend phases without repainting behavior

? How It Works (Logic)

• Uptrend starts when price closes above the Upper Band
• Downtrend starts when price closes below the Lower Band
• Trend ends / Sideways begins when price returns to the Middle Band

This creates a clear structure-based trading framework, ideal for:

• Breakout traders
• Scalpers
• Trend-following systems
• EA (Expert Advisor) integration

? Best Use Cases

• Scalping on M1 – M15
• Gold (XAUUSD), Forex, Indices
