SessionVolumeProfile

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

    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.
