Description

This function identifies the difference of the last and the open. This difference is the length of the real body.

Formula

RealBodyLen(instrument, targetBar)=begin

  retval = NONUM

  cOpen = GetPrice(instrument, BATE_OPEN, targetBar, 0)

  cLast = GetPrice(instrument, BATE_CLOSE, targetBar, 0)

  if cLast != NONUM AND cOpen != NONUM then begin

    retval = cLast - cOpen

  end

  retval

end

Parameters

instrument

An instrument.

targetBar

The index of the bar you want to evaluate. 0 is the current bar, 1 is the first bar back, etc.

Return Value

The real body length.
