// MACD parameters
fastLength = input(12, title="Fast EMA Length")
slowLength = input(26, title="Slow EMA Length")
signalSmoothing = input(9, title="Signal Smoothing")
// Compute MACD components
[macdLine, signalLine, _] = ta.macd(close, fastLength, slowLength, signalSmoothing)
// Detect crossovers
bullishCrossover = talib.cross(macdLine, signalLine)
bearishCrossover = talib.cross(signalLine, macdLine)
// Plot Buy and Sell signals
