GetBar

Description

This formula decrements a bar reference. The Chart() function orients the current bar to -1. Many formulas are written to refer to the current bar as 0. To use such formulas in Aspen, use this function to decrement the value appropriately.

Formula

GetBar(targetBar)=targetBar-1

Parameters

targetBar

This parameter specifies the index to the bar you want to retrieve. 0 is the current bar, 1 is the first bar back, etc.

Return Value

A decremented index to a bar.

Examples

LongWhiteForm(instrument, targetBar)={

  return = FALSE

  if BodyPercent(instrument, targetBar) > CLONG then {

    if RealBody(instrument, targetBar) > CLONGREAL then {

      if vchart(instrument.last[GetBar(targetBar)]) > vchart(instrument.open[GetBar(targetBar)]) then return = TRUE

    }

  }

  return

}
