>>
>>1. Let's say the market has been rising

>>3. The highest close is always used, even if there has been a series of
>>lower
>> closes since the highest close.
>>4. If the market closes below the volatility indicator, then for the next
>>day, the current
>> reading of the volatility indicator is added to the lowest close.
>>5. This step is followed each day until the market closes above
>> the trailing volatility indicator.
>>6. We now have a definition of the trend. An upward trend exists as long
as
>>the
>> volatility indicator is below the market
>>7. A downtrend is in force if the volatility indicator is above the
market.

>>Volatility Index - Wilder
>>
>>rev. 01/06/97
>>
>>In his book New Concepts in Technical Trading Systems, J. Welles Wilder
Jr.
>>talks about volatility and describes his Volatility Index and Volatility
>>System.
>>Both of these can be performed in MetaStockT for Windows version 6.x.
>>This document describes how to construct the index.
>>
>>The Volatility Index (VI) is described by Wilder as:
>>
>>VI Today = (13 * VI Prev + TR1) / 14 *where TR1 is today's true range.
>>
>>He defines the true range as the greatest of the following:
>>
>> 1. The distance from today's high to today's low
>> 2. The distance from yesterday's close to today's high, or
>> 3. The distance from yesterday's close to today's low.
>>
>>In MetaStock version 6.0 or higher you would use the Prev function and an
>>one period
>>Average True Range to construct the Volatility Index.
>>
>>The custom formula is written as:
>>
>>VI Today = (13 * Prev + ATR(1)) / 14
>>
>>=========================================================
>>Average True Range - Wilder
>>
>>MSK6.5 Help/manual p.420-421
>>
>>In his book, New Concepts In Technical Trading Systems, Wilder defines a
>>trading system
>>that uses the Average True Range.
>>He also provides details on calculating the Average True Range and the
>>trading system.
>>The Average True Range also can be interpreted using the same techniques
>>that are used
>>with the other volatility indicators. Refer to the discussion on Standard
>>Deviation for additional
>>information on volatility interpretation (see Standard Deviation).
>>
>>Interpretation
>>The True Range indicator is defined by Wilder to be the greatest of the
>>following for each period:
>>· The distance from today's high to today's low.
>>· The distance from yesterday's close to today's high.
>>· The distance from yesterday's close to today's low.
>>The Average True Range is simply the average of the true ranges over the
>>past x periods
>>(where x is specified by the user).
>>
>>Parameters
>>The parameters for the Average True Range are shown below. These
>>parameters are specified
>>at the time the indicator is plotted. You can edit the parameters of an
>>existing plot by right-clicking
>>on the indicator and choosing Properties from the shortcut menu.
>>
>>Time Periods. Enter the number of time periods to use when calculating
>>Average True Range.
>> The term "time periods" refers to days if the
>>chart contains daily data, weeks for
>> weekly data, etc.
>>
>>Custom indicator
>>SYNTAX atr( PERIODS )
>>FUNCTION Calculates the predefined Average True Range indicator.
>>EXAMPLE atr( 20 )

>>Average True Range - Welles Wilder (for MetaStock v6.5)
>>
>>(Written by Ton Maas-981225-Amsterdam-the Netherlands)
>>
>>The True Range is the greatest of the following differences:
>>
>>a) Today's high to today's low
>>b) Today's high to yesterday's close
>>c) Today's low to yesterday's close
>>
>>The range is normally the "high - low" . However, any time
>>the value of yesterday's close is not within the range of
>>today's bar, rule b) or rule c) applies.
>>
>>As with most other indicators, the periodic value is summed
>>and smoothed to create the final indicator.
>>
>>The Average True range is a 1-day Moving Average of the True range.
>>
>>In Metastock(v6.5):
>>-Open the Indicator Builder
>>-Press New
>>-This will open the IB's Editor and display a new blanc formula layout
>>-In the "Name"-field type(or Copy+Paste) the name below
>>-In the "Formula"-field type(or Copy+Paste) the formula below
>>
>>Note:
>>The ATR indicator function is standard build-in in MetaStock(v6.x) and can
>>be used by typing ATR("periods") as its Syntax in the Formula field.
>>
>>Example: ATR(20) (=a 20-day True range average)
>> Mov(ATR(1),20,S) (=a 20-day Moving Average of a daily
>>True Range)
>>
>>The pre-defined ATR-indicator is prefered over the below printed formula,
>>for that
>>it will require the longer calculation time.

>>The value of tr() for any day is always positive or zero.
