/// DOSC: Derivative Oscillator
/// A momentum indicator that combines the Relative Strength Index (RSI) and the Moving Average Convergence Divergence (MACD) to identify potential trend reversals.
/// </summary>
/// <remarks>
/// The DOSC calculation process:
/// 1. Calculate the RSI
/// 2. Calculate the MACD of the RSI
/// 3. Calculate the signal line (SMA) of the MACD
/// 4. Subtract the signal line from the MACD to get the DOSC
///
/// Key characteristics:
/// - Combines RSI and MACD
/// - Oscillates above and below zero
/// - Positive values indicate bullish momentum
/// - Negative values indicate bearish momentum
/// - Crosses above zero suggest buying opportunities
/// - Crosses below zero suggest selling opportunities
///
/// Formula:
/// DOSC = MACD(RSI) - Signal(MACD(RSI))
