ZD periods: This parameter is the number of time periods used in the moving average of ZK. is refered to as The moving average top of %D and is plotted on the solid line ZK. 4. %D Method: This can be either expon- ential, simple or weighted moving. average to calculate ZD. I suggest exponential moving average. Thus, the default Stochastic Oscillator is a 5-day slow exponential %D. with a 3-day will be displayed as a solid line and the %D will be displayed as a dotted line .
