/// OBV: On Balance Volume
/// </summary>
/// <remarks>
/// On Balance Volume is a cumulative indicator that measures buying and selling pressure
/// by adding volume on up days and subtracting volume on down days. Developed by Joseph
/// Granville in 1963, it relates price changes to volume to predict price movements.
/// Cumulative indicator measuring buying/selling pressure: adds volume on up days, subtracts on down.
/// Divergences between price and OBV can signal potential reversals.
///
/// Calculation:
/// - If Close &gt; Previous Close: OBV = Previous OBV + Volume
/// - If Close &lt; Previous Close: OBV = Previous OBV - Volume
/// - If Close == Previous Close: OBV = Previous OBV (unchanged)
///
/// OBV is often used to confirm price trends. When price and OBV make higher highs and
/// higher lows, the uptrend is likely to continue. Divergences between price and OBV
/// can signal potential trend reversals.

/// Calculation: <c>if Close > Prev_Close: OBV += Volume</c>;
/// <c>if Close &lt; Prev_Close: OBV -= Volume</c>; otherwise unchanged.
