Hello,


please help me out to understand why the Indi works only when adding to the chart (Init) or when compiling code ?

I have checked, and it runs every ticks... but the line code below will never occur

if (i==0) Print(i); // It never happens

 HighestHighRecent=High[Highest(NULL,0,2,TTFbars,i-TTFbars+1)];

You are trying to read future bars.

I tried this :

      HighestHighRecent=High[Highest(NULL,0,2,TTFbars,i-TTFbars)];
      HighestHighOlder =High[Highest(NULL,0,2,TTFbars,i)];
      LowestLowRecent =Low[Lowest(NULL,0,1,TTFbars,i-TTFbars)];
      LowestLowOlder =Low[Lowest(NULL,0,1,TTFbars,i)];
// NOT WORKING BETTER

      HighestHighRecent=High[Highest(NULL,0,2,TTFbars,i)];
      HighestHighOlder =High[Highest(NULL,0,2,TTFbars,i)];
      LowestLowRecent =Low[Lowest(NULL,0,1,TTFbars,i)];
      LowestLowOlder =Low[Lowest(NULL,0,1,TTFbars,i)];
// NOT WORKING AT ALL

Any more help please?
