Micro fast trendline [sma]

Overview
Micro Fast Trendline is an automated trendline drawing tool that connects pivot points in real-time. It dynamically creates trendlines between consecutive pivot highs and pivot lows, extending them forward to visualize potential support and resistance trajectories.
How It Works
Pivot Detection System
The indicator uses a symmetric pivot detection algorithm:
1. Scans for pivot highs: local peaks with lower highs on both left and right sides
2. Scans for pivot lows: local troughs with higher lows on both left and right sides
3. Confirms pivots only after the specified number of right bars have formed
4. Default settings: 5 bars left + 5 bars right (customizable)

Trendline Construction
When a new pivot is detected:
- **For Pivot Highs**: Draws a descending trendline from the previous pivot high to the current one (bearish)
- **For Pivot Lows**: Draws an ascending trendline from the previous pivot low to the current one (bullish)
- Calculates the slope between the two pivots
- Extends the line forward based on that slope for the specified number of bars (default 30)

Line Management System
The indicator includes intelligent line management:
- **Maximum Lines Control**: Limits the number of displayed trendlines (default 4, max 10)
- **Automatic Cleanup**: Removes oldest lines when the maximum is exceeded
- **Extension Expiry**: Deletes lines after they've extended beyond their lifespan
- Uses arrays to track pivot history and associated trendline objects

Key Features
- **Automatic Drawing**: No manual trendline drawing required
- **Real-time Updates**: Creates new trendlines as pivots form
- **Slope-based Extension**: Projects trendlines forward using calculated slope
- **Memory Management**: Automatically cleans up old lines to prevent clutter
- **Dual Tracking**: Separate systems for bullish and bearish trendlines
- **Optional Pivot Markers**: Can display pivot points for validation
Parameters

Pivot Configuration
- **Left Bars** (default 5): Number of bars to the left of the pivot for confirmation
- **Right Bars** (default 5): Number of bars to the right of the pivot for confirmation
- Higher values = fewer but more significant pivots
Visual Configuration
- Show Pivot Points (default off): Display triangles at confirmed pivots
- Bullish Line Color (default dark green): Color for upward trendlines
- Bearish Line Color (default dark red): Color for downward trendlines
- Line Width (default 1): Thickness of trendlines
- Maximum Lines (default 4, range 1-10): Maximum concurrent trendlines
- Line Extension (default 30 bars, range 10-200): Forward projection length
Interpretation

Bullish Trendlines (Green)
- Connect consecutive pivot lows
- Act as dynamic support levels
- Upward slope indicates strengthening uptrend
- Price breaking below suggests weakening support

Bearish Trendlines (Red)
- Connect consecutive pivot highs
- Act as dynamic resistance levels
- Downward slope indicates strengthening downtrend
- Price breaking above suggests weakening resistance

Trading Applications
- **Breakout Trading**: Watch for price breaking extended trendlines
- **Support/Resistance**: Use as dynamic S/R levels
- **Trend Confirmation**: Slope direction confirms trend strength
- **Reversal Signals**: Multiple trendline breaks may indicate reversals

Technical Implementation
This indicator uses:
- Custom type definition (PivotData) to store pivot price, time, and line object
- Array-based data structure for efficient pivot history management
- Dynamic line objects with calculated slope extension
- Automatic memory cleanup to prevent performance degradation
- Separate processing loops for highs and lows to avoid conflicts

Originality Statement
This indicator features a unique approach to automated trendline creation:
- Implements a custom data structure combining pivot data with line objects
- Uses slope-based mathematical projection for realistic line extensions
- Employs an intelligent cleanup system that removes expired lines automatically
- Maintains separate arrays for bullish/bearish trendlines with independent management
- Projects trendlines forward using calculated slope rather than simple horizontal extension

The combination of pivot detection, slope calculation, and automated line lifecycle management creates a hands-free trendline system.

Best Practices
- Lower pivot bar settings (3-5) for faster, more responsive trendlines
- Higher pivot bar settings (7-15) for major swings and longer-term trends
- Adjust line extension based on your trading timeframe
- Reduce maximum lines on lower timeframes to avoid clutter
- Increase maximum lines on higher timeframes for historical context
