Description:
This is an MACD crossover formula, which draws yellow arrows at the crossover points.
Formula Parameters:
nFastLength: Default is 12.
nSlowLength: Default is 26.
nSmoothing: Default is 9.
nPriceSource: Default is Close (valid inputs: Open, High, Low, Close, HL/2, HLC/3 and OHLC/4).
nSimpleMA_TorF: Default is False (True = Simple Moving Average, False = Exponential Moving Average).
Notes:
If used on an intra-day interval, the arrows will be drawn or removed intra-bar as the conditions change.
