How It Works
ZigZag Detection: The indicator first identifies peaks and troughs using the built-in ZigZag indicator.

Trend Line Drawing:

Upper lines connect ZigZag highs

Lower lines connect ZigZag lows

Pattern Recognition:

For bullish setups, it looks for:

A low (point 1)

A higher high (point 2)

A higher low (point 3)
Then watches for a breakout above point 2

For bearish setups, it looks for:

A high (point 1)

A lower low (point 2)

A lower high (point 3)
Then watches for a breakout below point 2

Breakout Conditions:

The retracement between points 2-3 must be between RetraceDepthMin and RetraceDepthMax

Price must close beyond the trend line (point 2 level)

Signal Generation:

Places arrows at breakout points

Marks the 1-2-3 points with dots

Can trigger alerts when new signals appear

Cleanup:

Removes unnecessary trend lines after breakouts occur

Converts zero values to EMPTY_VALUE for cleaner display

Alert Messages
When a breakout occurs, the indicator can generate alerts with the format:
"[Symbol] [Timeframe] [buy/sell]!"

For example: "EURUSD M15 buy!"

Color Scheme
The color choices serve specific purposes:

Blue (DodgerBlue) for bullish elements (upper lines, buy arrows)

Red (OrangeRed) for bearish elements (lower lines, sell arrows)

Goldenrod for bullish pattern points

CornflowerBlue for bearish pattern points
