  Subject: [amibroker] Help with coding PREV alternative


  Hi, I am attempting to convert a Metastock formula with a PREV 
  statement. I have read a number of messages in Amibroker database and my 
  attempt is as follows.

  IH_Periods = Param("Initial High", 21, 10, 100,1);

  HH = IH_Periods - 1;

  Z = HHV(H,HH);
  Z = 0; // Initialize
  for(i=1;i<BarCount;i++)
  {
  PREV = Z[i-1]; // PREV is previous value of Z.
  }

  When I use PREV in a AB formula such as iif(A > B, XX, PREV) I get 0 
  (Zero) when A<B.......rather than the previous value of Z. Can I assign 
  a HHV to Z?)

  I hope I have explained this.

  Any help would be appreciated.

  TIA .... Keith
