I see.  I replace simple moveing average with wilders average and now the codes work same as the Amibroker built-in ADX


Thanks/ Tom

  The difference is in the way the calculations are smoothed. Wilder had
  his own method for calculating a moving average, and you get different
  values depending on whether you use his original method (from before the
  time when PCs were available), an exponential ma, a simple ma, weighted
  ma, etc.
