/**
 * Trend Line Auto
 *
 * Auto-draws trend lines based on fractal highs/lows detected via highest/lowest
 * over a period. Uses angle calculation to find the best-fit trend line connecting
 * the most recent fractal to a prior fractal within a segment range.
 * Lines are colored green (top/upper) and red/yellow (bottom/lower).
