Description:
Money Flow Indicator (Chaikin Oscillator)

 

Formula Parameters:

  • Fast : 3
  • Slow : 10

Notes:
Indicator plots Money Flow Indicator (Chaikin). This indicator looks to improve on Larry William's Accumulation Distribution formula The indicator subtracts a 10 period exponential moving average of the
AccumDist function from a 3 period exponential moving average of the AccumDist function.
