Description:
This Indicator plots Bill Williams Averages. 3Lines
Formula Parameters:
Long length: 13
Medium length: 8
Short length: 5
Displacement for long length: 8
Displacement for medium length: 5
Displacement for short length: 3
Notes:
This indicator calculates 3 Moving Averages for default values of
13, 8 and 5 days, with displacement 8, 5 and 3 days: Median Price (High+Low/2).
The most popular method of interpreting a moving average is to compare
the relationship between a moving average of the security's price with
the security's price itself (or between several moving averages).
