PatternScanner – Automatic Chart Pattern Detector for cTrader

PatternScanner is a visual chart-pattern detector for cTrader that automatically finds the most important classical reversal structures and draws them directly on your chart.

Instead of manually searching for patterns bar by bar, the indicator scans swing highs and lows in real time and highlights:

• Head & Shoulders (H&S) – bearish
• Inverse Head & Shoulders (INV H&S) – bullish
• Double Top (DT) – bearish
• Double Bottom (DB) – bullish
• Wolf Ears (WOLF) – a “double–top style” pattern with a slightly higher second peak

Each pattern is marked with a label (H&S, INV H&S, DT, DB, WOLF) and a set of lines that outline the structure, so you can see the pattern at a glance without guesswork.

Key Features

• ✅ Automatically detects swing highs and lows and builds patterns from them
• ✅ Identifies Head & Shoulders and Inverse Head & Shoulders with a drawn neckline
• ✅ Detects Double Tops / Double Bottoms and connects the two key highs/lows
• ✅ Recognizes Wolf Ears without overlapping the standard Double Top signal
• ✅ Draws zig-zag lines between swing points to visually outline each pattern
• ✅ Built-in legend in the top-left corner explaining all pattern codes (H&S, INV H&S, DT, DB, WOLF)
• ✅ Fully overlay – everything is drawn on the price chart, no extra sub-window needed

Inputs / Parameters

• Swing Strength – Number of bars used to confirm a swing high/low (pivot sensitivity).
• Level Tolerance (%) – How similar two highs/lows must be to be considered “at the same level”.
• Detect Head & Shoulders – Enable/disable H&S detection.
• Detect Inverse H&S – Enable/disable inverse H&S detection.
• Detect Double Top/Bottom – Enable/disable DT/DB detection.
• Detect Wolf Ears – Enable/disable Wolf Ears detection.
• Label Font Size – Size of the on-chart pattern labels.
• Bearish Color – Color used for bearish patterns (H&S, DT, WOLF).
• Bullish Color – Color used for bullish patterns (INV H&S, DB).
• Wolf Ears Color – Dedicated color for the WOLF pattern lines and label.

How It Draws the Patterns

• Head & Shoulders / Inverse H&S
• • Zig-zag line through the 5 key swing points (shoulder – head – shoulder).
  • Neckline drawn as a dotted trendline between the two lows (for H&S) or two highs (for inverse H&S).
• Double Top / Double Bottom
• • A label (DT or DB) at the second top/bottom.
  • A trendline connecting the two highs (DT) or two lows (DB).
• Wolf Ears
• • Zig-zag through the High–Low–High structure.
  • Dotted resistance line through the two peaks.
  • Wolf Ears is only signaled when the second high is clearly higher than the first, so it doesn’t overlap with a normal Double Top.

How to Use

Attach PatternScanner to any symbol and timeframe and let it act as a visual radar for major reversal structures:

• Spot potential reversal zones around H&S, DT/DB and WOLF patterns
• Combine with your own filters (trend, volume, support/resistance) for trade entries
• Use the legend in the top-left corner to quickly read what pattern is being shown

It’s not a standalone trading system, but a powerful pattern-recognition tool that saves you time and helps you focus on the most interesting structures on the chart.
