Syntax:
|
1 |
VolumeAdjustedAverage[period](price) |
Where:
- period= calculation period used for the Volume Adjusted Moving Average (default period is 20)
- price= applied price or data serie into the formula of the VAMA

VolumeOscillator[S,L] |
Variation % = 100 * [(short average – long average) / long average]
Return value of the Volume of the Price Rate of Change over the last N periods.
Syntax:
|
1 |
VolumeROC[N] |
The calculation is the same as for a ROC but calculated on the volume.
Return value of the Weighted Moving Average over the last N periods for the selected price.
Syntax:
|
1 |
WeightedAverage[N](price) |
Return value of a Wilder Moving Average over the last N periods for selected price.
Syntax:
|
1 |
WilderAverage[N](price) |
Example:
|
1 2 3 4 5 6 |
long = WilderAverage[26](close) short = WilderAverage[12](close) WilderMACD = long - short RETURN WilderMACD |
Return value of the Williams R% oscillator over the last N periods for the selected price.
Syntax:
|
1 |
Williams[N](close) |
Calculation :
The parameter is the number of days used in calculation of %R.
((High on n period – today’s close) / (high on n period – low on n period)) * (-100)
Return value of the Williams Accumulation Distribution indicator of selected price.
Syntax:
|
1 |
WilliamsAccumDistr(price) |
Calculation :
TRH = the highest of (yesterday’s close or today’s high)
TRL = the smallest of (yesterday’s close or today’s low)
If the today’s close > yesterday’s close then A/D = today’s close – TRL
if the today’s close < the yesterday’s close then A/D = today’s close – TRH
If the today’s close = yesterday’s close then A/D = 0
A/D William = today’s A/D + yesterrday’s A/D William
