Store DEMA Indicator High/Low

  Hi,

  Is there a way to store or calculate the highest / lowest value that an indicator reached for each bar?

  MyIndicator = DEMA[Variable](Close)

  MyIndicatorHi = Highest value that MyIndicator reached during the formation of a particular bar

  MyIndicatorLo = Lowest value that MyIndicator reached during the formation of a particular bar

  Many Thanks.

  There yo go:

  MyIndicator = DEMA[Variable](Close) MyIndicatorHi = Highest[variable](MyIndicator) MyIndicatorLo = Lowest[variable](MyIndicator)

  1 2 3

  MyIndicator   = DEMA[Variable](Close) MyIndicatorHi = Highest[variable](MyIndicator) MyIndicatorLo = Lowest[variable](MyIndicator)

  Hi Roberto,

  Many thanks for your response but I think my request was not clear enough.

  In your code the Highest function returns the highest CLOSE value in the past “variable” periods.
  What I would like to store/calculate is the highest HIGH/LOW value per bar (so only for 1 period)

  MyIndicatorHi = DEMA[Variable](High) won’t work either as it uses the High value for current and past “variable” periods.
  What I am looking for is some way to use the High (or Low) value for the current bar but the Close value for past “variable” periods.

  A simple 3 period MA would be:
  MyMA = Close + Close[1] + Close[2]
  MyMAHi = High + Close[1] + Close[2]
  MyMALo = Low + Close[1] + Close[2]

  But how to calculate this for an Infinite Impulse Response (IIR) filter with a variable lookback period such as a DEMA is what I am trying to do.

  CORRECTION:

  A simple 3 period MA would be:
  MyMA = (Close + Close[1] + Close[2]) / 3
  MyMAHi = (High + Close[1] + Close[2]) / 3
  MyMALo = (Low + Close[1] + Close[2]) / 3

  It’s not possible, when you calculate an average, whatever it is, such as:

  Average[10](close)

  1	Average[10](close)

  you cannot ask it to use HIGH for just the most recent period.

  You could use

  (Average[10](close) + high) / 2

  1	(Average[10](close) + high) / 2

  but it’s not the same.

  Thanks for that Roberto. It gave me a new idea…
  Do you perhaps have the ProRealTime code to calculate the DEMA?

  DEMA is quite simple to calculate:

  p=20 a = exponentialaverage[p](close) b = exponentialaverage[p](a) mydema = (2*a)-b return mydema

  1 2 3 4 5 6 7

  p=20   a = exponentialaverage[p](close) b = exponentialaverage[p](a) mydema = (2*a)-b   return mydema
