//    - Optimized parameters (8,21,5) for crypto
//    - MACD line calculation accuracy
//    - Signal line calculation accuracy
//    - Histogram calculation validation
//    - Parameter sensitivity testing
//
// 2. SIGNAL DETECTION TESTS (5 tests):
//    - Zero line crossover detection (primary signals)
//    - Signal line crossover detection (secondary signals)
//    - False signal prevention
//    - Crossover accuracy validation
//    - Signal timing verification
//
// 3. QUALITY FILTERS TESTS (5 tests):
