Volatility Time Bands (VTBands)

This study looks at the time of day for a chart period and creates an average of the range for that bar over a user-defined look back period. It then places 1, 2, and 3 standard deviations around the opening price of that bar.

The study can be applied to:

      Bar chart

      Candlestick chart

      Equalize Sessions chart

      Fill Gap chart

      Line chart

      TBTF chart

      Yield chart

The study appears on the chart as seven curves. VTBLo1, VTBLo2, and VTBLo3 curves reference 1, 2, 3 standard deviations below the opening price and VTBHi1, VTBHi2, VTBHi3 to 1, 2, 3 standard deviations over the opening price. VTBMidPoint curve corresponds to midpoint of Lo1 and Hi1. All curves are overlaid.

You are able to turn off display of VTBMidPoint curve.

Philosophy

Volatility Time Bands have multitude of applications on all asset classes and timeframes down to the 15 minute chart. For a full explanation see chapter 1 of Trading Time and various case studies throughout the book. This study also has many connections with the daily commentaries written that are Profile based on over 40 markets.

Nearly all momentum based indicators look at momentum on a continuous basis and have no automatic adjustment for the time of day that it is, or what the normal behavior is at that time. Volatility Time Bands analyses both the time of day and its relationship to range. The study analyses the current time of days range in relationship to its user defined average of range for that time of day in that timeframe chart. It then places 1 and 2 and 3 standard deviations around the opening of the current bar. In contrast to Range Deviation Pivots there is no skew for trend so the bands are symmetrical. The lowest timeframe for computation is set at a 15 minute bar.

Interpretation

Volatility Time Bands have multitude of applications on all asset classes and timeframes down to the 15 minute chart. For a full explanation see chapter 1 of Trading Time and various case studies throughout the book.

Volatility Time Bands have various applications.

      What is the trend? Are we above or below the bands?

      How strong is the trend? Where is price in relationship to the first up or down band?

      Is the trend accelerating? The relationship between the first bands, any closes outside the 3rd, and what the time of day actually is

      Has the trend changed? Has price switched from one side of the bands to the other side?

      Has the trend reached an extreme? Is it the correct time of day, is it doing so on multiple timeframes and does it connect with Range Deviation Pivots?

      Is that extreme likely to mark the end of the trend? Are we overbought or oversold? Are we at a major Market Profile support or resistance point?

All of these questions have applications, especially from a day trading point of view. One of the most common uses is to identify the trend and if it is up, place a limit order to buy at the 1 band down. The connection between multiple timeframes is also very powerful. A confluence of the 3rd band on the 15, 30 and 60 minute chart provides a firm reference of an extreme. Volume can rise if it is linked to Profile or the Range Deviation Pivots.

Closes outside of the 3rd band indicate activity beyond the normalized and are especially referenced on bars that have been influenced by news stories or statistics.

VTBands Parameters

Name

Default

Definition

Display

On

The ability have the mid point visible.

Len

22

The lookback period to compute the history of range.

StdMult1

1.0

The first bands.

StdMult2

2.0

The second bands.

StdMult3

3.0

The third bands.

Hide Midpoint

False

Determines whether the midpoint is displayed.

Extra Steps

1000

The maximum lookback period for comparing range. A number too high may degrade performance, while a number too low will prevent the study from being displayed. The approximate calculation is Extra Steps = “Number of bars per day” * Len.

Price

Open

Price around which standard deviations are placed.
