EMA value discrepancy between preset indicator and code

  Please help to solve the issue.

  I use the following code to graph EMA12, EMA144 and EMA169, it shows that the value of EMA12 is exactly the value with the default indicator in the PRT system (as shown in the attached jpg). However, there are discrepancy for EMA 144 and EMA169, so which one is the correct one?

  DEFPARAM CumulateOrders = False indicator1 = ExponentialAverage[12](close) c1 = (close CROSSES OVER indicator1) indicator3 = ExponentialAverage[144](close) c2 = (indicator1 >= indicator3) indicator5 = ExponentialAverage[169](close) c3 = (indicator1 >= indicator5) IF c1 AND c2 AND c3 THEN BUY 1 CONTRACT AT MARKET ENDIF graph indicator1 graph indicator3 graph indicator5 c4 = (close crosses under indicator1) if c4 then SELL AT MARKET endif

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

  DEFPARAM CumulateOrders = False     indicator1 = ExponentialAverage[12](close) c1 = (close CROSSES OVER indicator1) indicator3 = ExponentialAverage[144](close) c2 = (indicator1 >= indicator3) indicator5 = ExponentialAverage[169](close) c3 = (indicator1 >= indicator5)   IF c1 AND c2 AND c3 THEN BUY 1 CONTRACT AT MARKET ENDIF graph indicator1 graph indicator3 graph indicator5   c4 = (close crosses under indicator1)   if c4 then SELL AT MARKET endif

  I think it’s a rounding issue between ProOrder and ProBuilder; the longer the periods, the (slightly) higher the difference.

  Bear in mind that prices are plotted with only 1 decimal digit, while EMAs show more; if you only consider one decimal digit then they are identical.

  Such slightly differences do not usually affect operations.
