Description:
Colors MACD histogram green when rising, red when falling. All inputs to MACD are configurable including histogram color. The display of the MACD histogram, Signal, MACD and MACD drop-lines can be turned on/off individually. The color of the drop-lines will match the up/down colors of the histogram up/down color settings. When the MACD is positive, the drop-down lines will be the up color and down color when the MACD is negative.
Formula Parameters:
Fast Length: Default is 12
Slow Length: Default is 26
Smoothing Length: Default is 9
Price Source: Default is Close, [Open, High, Low, Close, HL/2, HLC/3, OHLC/4]
MA Type: Default is SMA, [SMA, EMA]
MACD Hist Up Color: Default is green
MACD Hist Down Color: Default is red
MACD Color: Default is red
MACD Sig Color: Default is blue
Display Histogram: Yes, [Yes, No]
Display MACD: Yes, [Yes, No]
Display Signal: Yes, [Yes, No]
Display Drop Lines: Yes, [Yes, No]
Notes:
NA
