Variable List Abbreviation: ExpMvAvg
Variable Mode(s): Standard, Stock, Futures1, and Futures2
[ Note: uses selected close variable in Stock, Futures1, and Futures2 modes ]
Parameter(s): ExpMvAvg factor
Smoothes values with later values having an exponentially decreasing affect on the overall average. The exponential factor can be approximated as 2/(n+1) where n is the number of time periods that would be used for the equivalent length simple moving average.
ExpMovAvg = value*factor + OldAverage*(1.0-factor)
Initially average set to first value
Exponential factor must be greater than zero and less than one
