Variable MA Formula- Updated
Vidya 21, 5
Vidya Explanation
Vidya using P variable, version I
Vidya with P variable, version II
Volatility % Indicator
Volatility Difference

Volatility Trade in Gold
Volatility Bands as a Long Term Strategy
Volatility Over 16 Weeks
Volume Accumulation Percentage
Volume Based Exploration
Volume Oscillator Wave

Variable MA Formula- Updated

periods:=Input("periods",1,244,89);
VariableMA511( mp() , periods)

Equis put this function in for me. It uses VHF rather than CMO. Unlike the present version,
this is better.

Vidya 21, 5

This is the MetaStock code for VIDYA 21,5 which applies to the article "Breaking Out Of
Price Channels" by Gerald Marisch in the TASC January 1998 edition.

Length:=Input("Length",1,200,21);
Smooth:=Input("Smoothing",1,200,5);
AbsCMO:=(Abs(CMO(C,Length)))/100;
SC:=2/(Smooth+1);
VIDYA:=If(Cum(1)<=(Length+1),C,(SC*AbsCMO*CLOSE)+(1-(SC*AbsCMO))*PREV);
VIDYA

Vidya with P variable, version II

My version of Tushar Chande's Vidya, using the P variable

Vidya{P}
Periods:=Input("length of MA",5,100,20);
K:=Stdev(P,5)/Mov(Stdev(P,5),20,S);
A:=(2/(Periods+1));
Vidya:=A*K*(P)+(1-A*K)*Ref(P,-1);
Vidya;

Tar(SZ)an Long
C-(((462*Mov(C,34,E))-(420*Mov(C,13,E))+(490*(Mov(Mov(C,13,E)-
Mov(C,34,E),89,E))))/42)

Vidya Explanation

Vidya is a subject that comes up with some regularity. It's actually available in MetaStock as
the Variable Moving Average (Mov(C,n,V) but Equis, for their own inscrutable reasons,
choose not to identify it by name. If you refer to the MetaStock manual, be aware that there
is a typo in the formula (0.078 should read 0.78). Two or three years ago I coded the
version given in TAS&C and it overlaid the MetaStock version precisely, except that at the
time the MetaStock version was not correctly initialised -- this has since been corrected.
Equis acknowledged the typo at the time, but have done nothing about it.

As far as the 'circular reference' is concerned, you are right that eventually you run out of
data. However adding a portion of yesterday's value to a portion of today's value is common
to several indicators, such as the Exponential Moving Average. If no provision is made, then
usually the indicator will start with a value of zero, rise rapidly at first, then take some time
to stabilise.

One answer is to initialise it. For a Vidya of the close, period N, you can initialise with
something like "If(Cum(1) < N, C,{else} ...)" with the Vidya formula as the 'else'. Then at
day N the indicator uses the (N-1) close for yesterday's data and takes much less time to
stabilise.

Vidya using P variable, version I

Here is a version of Vidya using a P variable that matches MetaStock's built-in Variable
Moving Average. You can overlay them in different colours on the same chart to satisfy
yourself that they are indeed the same (but remember to use the same number of periods).
There is a small difference at the start due to different initialisation, after which they are
identical. The coding is spelled out for the benefit of anyone studying the book. It can be
adapted by adding a variable input for the CMO length (9), or made universal by replacing
each C with a P, or the Abs(CMOsc) can be replaced with a different volatility index that
ranges between 0 and 1.

{Vidya (Chande)}

Pds:= Input("Number of Periods?",1,1000,20);
Alpha:= 2/(Pds+1);

{Chande Momentum Oscillator}
{UD = Up day}
{DD = Down day}
UD:= Sum((C-Ref(C,-1))*(C>Ref(C,-1)),9);
DD:= Sum((Ref(C,-1)-C)*(C<Ref(C,-1)),9);
CMOsc:= (UD-DD)/(UD+DD);

k:= Abs(CMOsc);

Vidya:= (Cum(1) < Pds) * C + (Cum(1)>=Pds) * ((Alpha * k * C) + (1-Alpha
* k) * PREV);

Volatility % Indicator

You can easily create the Volatility% Indicator from William Brower’s article in MetaStock for
Windows. First choose Indicator Builder from the Tools menu in MetaStock. Next choose
New and enter one of the following formulas:

Formula for MetaStock 6.5

Volatility%

Lookback := Input("Time Periods",1,1000,50);

HighVolatility := Input("High Volatility %",.01,100,3);

100 * Sum(100 * ATR(1)/CLOSE > HighVolatility, Lookback)/Lookback

Formula for earlier versions of MetaStock for Windows

Volatility%

100 * Sum(100 * ATR(1)/CLOSE > 3, 50)/50

Now drag the Volatility% from the Indicator QuickList and drop it on the desired chart.

Volatility Trade in Gold

"A Volatility Trade In Gold" by David S. Landry, CTA, Technical Analysis of Stocks &
Commodities, page 87.

In this article the author gives formulas for three indicators MetaStock. The formulas as
given will work in all versions of MetaStock. However, there is an error in the formula the
author names Volatility 12 EMA. The formula should be: Mov((Fml("CONHV4") + Fml
("CONHV6") + Fml("CONHV10"))/3,12,e)

Here are formulas for version 6.5 and higher of MetaStock for Windows. These formulas use
Inputs which allow you to select the time periods when you plot the formulas.

David Landry Historical Volatility

Num:=Input("Number Of Periods For Numerator",1,100,4);
Den:=Input("Number Of Periods For Denominator",2,1000,100);
(Log(C/Ref(C,-1)),Num)/Std(Log(C/Ref(C,-1)),Den)

David Landry Average Historical Volatility

Den:=Input("Number Of Periods For Denominator",2,1000,100);
((Std(Log(C/Ref(C,-1)),4)/Std(Log(C/Ref(C,-1)),Den))+(Std(Log(C/Ref(C,-
1)),6)/Std(Log(C/Ref(C,-1)),Den))+(Std(Log(C/Ref(C,-1)),10)/Std(Log(C/Ref(C,-
1)),Den)))/3

David Landry EMA of Historical Volatility

Den:=Input("Number Of Periods For Denominator",2,1000,100);
EMA:=Input("Number Of Periods For EMA",2,100,12);
Mov(((Std(Log(C/Ref(C,-1)),4)/Std(Log(C/Ref(C,-1)),Den))+(Std(Log(C/Ref(C,-
1)),6)/Std(Log(C/Ref(C,-1)),Den))+(Std(Log(C/Ref(C,-1)),10)/Std(Log(C/Ref(C,-
1)),Den)))/3,LastValue(EMA),E)

Note: Standard deviation information was not included here because the way these formulas
are being used, any standard deviation being used would return an identical value as 1
standard deviation.

Volatility Bands as a Long Term Strategy

This article "Volatility Bands As A Long Term Strategy", by Ahmet Tezel, Ph.D., and Suzan
Koknar-Tezel, M.S., which appears in this issue introduces two different volatility band
trading systems. One system uses bands based on moving averages and the other is based
on bands which use regression. To plot the Moving Average Asymmetric Volatility Price
Bands in MetaStock for Windows, simply plot Bollinger Bands using 11 periods and 1.7
standard deviations. Then click your right-mouse button while the cursor is over the lower
band and choose properties. Change the standard deviations to 2. This plot will now appear
exactly as the bands discussed in the article.

To plot the Regression Asymmetric Volatility Price Bands in Metastock for Windows, simply
plot Standard Error Bands using 21 periods, 1 for standard errors, and 1 for the smoothing
periods. Then click your right-mouse button while the cursor is over the lower band and
choose properties. Change the standard errors to 1.5.

To recreate the systems in MetaStock for Windows, choose System Tester from the Tools
menu. Next choose New and enter the following trading rules and stop conditions. After
entering this information, choose Options and change the trade delay to 1, then change the
Trade Price to Open. If you have MetaStock 6.5 enter the first set of formulas. MetaStock
6.5 allows variables which will allow you to change the periods when testing much more
easily.

Volume Accumulation Percentage

I contacted David Vomund by e-mail and he was kind enough to mail me the equations
required to calculate the VAP. I've programmed them in MetaStock as follows:

VOLUME ACCUMULATION PERCENTAGE
Periods:=Input("Time Periods",1,60,21);
X:=(2*C-H-L)/(H-L);
TVA:=Sum(V*x,Periods);
TV:=Sum(V,Periods);
VA:=100*TVA/TV;
VA

Volume Based Exploration

1. Stocks with volume > 10x the previous day's volume

2. Stocks where the above situation hasn't occurred during the previous 60 days.

ColA = if(V > 10*ref(V,-1),1,0)

ColB = ref(barssince(V>10*ref(V,-1)),-1)

Filter: ColA=1 and ColB>60
