Description

Where Wilder's RSI is calculated by determining the difference between the open and the close, Cutler's RSI is calculated by determining the difference between the previous bar's close and the current close (the net change).

 

 

Formula

CutlersRSI(SERIES, Periods=14, Bate=6)=begin

  SumUp = 0

  SumDown = 0

  RS = 1

  currentPrice = NONUM

  previousPrice = NONUM

  difference = 0

  

  for i = -1 to (Periods - 2) begin

    currentPrice = GetPrice($1, Bate, i, Periods)

    previousPrice = GetPrice($1, Bate, (i + 1), Periods)

    difference = currentPrice - previousPrice

    if difference > 0 then SumUp = SumUp + difference

    if difference < 0 then SumDown = SumDown + abs(difference)

  end

  if SumDown > 0 then RS = SumUp / SumDown

  retval = GetRS(RS)

  retval

end
