Re: [amibroker] AFL syntax for nested IIF ?

Thanks Herman. I know that in programmers land there are a thousand possible ways to Rome. I even can put all the to do's in a function and then call the function from within the IIF etc. etc. But that's not how it should be programmed and that's not my question. I just don't know the syntax of the double IIF in AFL and would like to know that. The frustrating thing for me is that I cannot find it in the AFL manual. Don't forget that in AFL the double IIF has a special function. It made to handle arrays. So there is no need for a loop ...

Ton.

  Not sure what you are trying to do but often using a loop may simplify things:




  FirstVisibleBar = Status( "FirstVisibleBar" );

  Lastvisiblebar = Status("LastVisibleBar");

  for( b = Firstvisiblebar; b < Lastvisiblebar AND b < BarCount; b++)

         {

         if( BarNumAct[b] <= 21 )

                 {

                 Highs[b] = C[b];

                 Lows[b] = C[b];

                 Range[b] = (H[b] - L[b])/2;

                 }

         }
