The On screen MACD indicator is drawn on the main price chart. Slow ЕМА is used as the zero line.

It has four adjustable parameters:

• Fast EMA period
• Slow EMA period
• Signal period – signal line calculation period
• Applied price – price used for calculation

Calculations:

MACD = EMA(Applied price, Fast EMA period)
Zero = EMA(Applied price, Slow EMA period)
Signal = Zero + SMA(RAW, Signal period)
Histogram = Zero + MACD - Signal

where:

RAW = MACD - Zero
