PINE LIBRARY
SessionVolumeProfile
Updated
Library "SessionVolumeProfile"
Analyzes price & volume during regular trading hours to provide a session volume profile analysis. The primary goal of this library is to provide the developer with three values: the value area high, low and the point of control. The library also provides methods for rendering the value areas and histograms. To learn more about this library and how you can use it, click on the website link in my profile where you will find a blog post with detailed information.
debug(vp, position)
Helper function to write some information about the supplied SVP object to the screen in a table.
Parameters:
vp (Object): The SVP object to debug
position (string): The position.* to place the table. Defaults to position.bottom_center
getLowerTimeframe()
Depending on the timeframe of the chart, determines a lower timeframe to grab volume data from for the analysis
Returns: The timeframe string to fetch volume for
get(volumeProfile, lowerTimeframeHigh, lowerTimeframeLow, lowerTimeframeVolume)
Populated the provided SessionVolumeProfile object with vp data on the session.
Parameters:
volumeProfile (Object): The SessionVolumeProfile object to populate
lowerTimeframeHigh (float[]): The lower timeframe high values
lowerTimeframeLow (float[]): The lower timeframe low values
lowerTimeframeVolume (float[]): The lower timeframe volume values
drawPriorValueAreas(todaySessionVolumeProfile, extendYesterdayOverToday, showLabels, labelSize, pocColor, pocStyle, pocWidth, vahlColor, vahlStyle, vahlWidth, vaColor)
Given a SessionVolumeProfile Object, will render the historical value areas for that object.
Parameters:
todaySessionVolumeProfile (Object): The SessionVolumeProfile Object to draw
extendYesterdayOverToday (bool): Defaults to true
showLabels (bool): Defaults to true
labelSize (string): Defaults to size.small
pocColor (color): Defaults to #e500a4
pocStyle (string): Defaults to line.style_solid
pocWidth (int): Defaults to 1
vahlColor (color): The color of the value area high/low lines. Defaults to #1592e6
vahlStyle (string): The style of the value area high/low lines. Defaults to line.style_solid
vahlWidth (int): The width of the value area high/low lines. Defaults to 1
vaColor (color): The color of the value area background. Defaults to #00bbf911)
drawHistogram(volumeProfile, bgColor, showVolumeOnHistogram)
Given a SessionVolumeProfile object, will render the histogram for that object.
Parameters:
volumeProfile (Object): The SessionVolumeProfile object to draw
bgColor (color): The baseline color to use for the histogram. Defaults to #00bbf9
showVolumeOnHistogram (bool): Show the volume amount on the histogram bars. Defaults to false.

Release Notes
v2 Removed incorrect comments.Release Notes
v3 Updated library to use the lower timeframe bars to determine the session. This makes the code work for futures.Updated:
get(volumeProfile, lowerTimeframeHigh, lowerTimeframeLow, lowerTimeframeVolume, lowerTimeframeTime, lowerTimeframeSessionIsMarket)
Populated the provided SessionVolumeProfile object with vp data on the session.
Parameters:
volumeProfile (Object): The SessionVolumeProfile object to populate
lowerTimeframeHigh (array<float>): The lower timeframe high values
lowerTimeframeLow (array<float>): The lower timeframe low values
lowerTimeframeVolume (array<float>): The lower timeframe volume values
lowerTimeframeTime (array<int>): The lower timeframe time values
lowerTimeframeSessionIsMarket (array<bool>): The lower timeframe session.ismarket values (that are futures-friendly)
