Description

This formula adds the prices in a range.

Formula

Summation(instrument, price, length, targetBar)=begin

  i=0

  total=0

  if length > 0 then begin

    while i < length do begin

      total = total + GetPrice(instrument, price, i, length)

      i=i+1

    end

  end

  total

end

Parameters

The bar, as oriented with the current bar, you want to evaluate.

Return Value

A sum

Examples

...

  UpEQ = Summation(instrument, BATE_INDEXxCLOSE, Length, targetBar) - Length * AveragePrice(instrument, BATE_BARINDEX, Length, targetBar) * AveragePrice(instrument, BATE_CLOSE, Length, targetBar)
