/// TEMA: Triple Exponential Moving Average
/// </summary>
/// <remarks>
/// TEMA uses triple smoothing to reduce lag even further than DEMA.
/// Uses triple smoothing to further reduce lag beyond DEMA.
/// Excellent for fast trend identification with minimal overshoot.
///
/// Calculation:
/// EMA1 = EMA(input)
/// EMA2 = EMA(EMA1)
/// EMA3 = EMA(EMA2)
/// TEMA = 3 * EMA1 - 3 * EMA2 + EMA3
///
/// O(1) update:
/// Uses three EMA instances, each with O(1) update complexity.
///
/// IsHot:
/// Becomes true when the TEMA step response converges to within 5% error.
/// This happens when the third EMA's error factor drops below ~9% (approx 2.43/alpha steps),
/// which is faster than the standard EMA convergence (3/alpha steps).
/// Calculation: <c>TEMA = 3×EMA1 - 3×EMA2 + EMA3</c> (cascaded EMAs).
/// </remarks>
/// <seealso href="Tema.md">Detailed documentation</seealso>
