Hi Allen, Toof is correct. It is a moving average that we create of the weekly v-Wave raw data. I think it is a 26 week eMA that is used but haven't looked at the spreadsheet in a while. JD's been kind enough to keep it up for a long time. JD reports the v-Wave weekly but that is the "smoothed" data. He also reports the Oscillator which gives us a direction and rate signal.
So, there is the raw v-Wave data, the 26 week eMA of that data and the difference between those two is the v-Wave Oscillator. A positive integer for the Oscillator indicates the raw data is showing a higher risk value than the eMA. A negative integer indicates the opposite. Rising risk trends are when the integer is positive, falling risk trends are when the integer is negative.
