It is coded to make the call once every new bar, and like clockwork, every time it makes that call, the memory usage increases until of course it cannot increase any more. I also make some calls on another custom indi, and that doesn't do the same thing. If I disable the Supertrend call from my code, then they memory usage remains constant. Is there anything in the SuperTrend indi that might not play nicely with iCustom ?

My Code is very simple:

Code: Select all

 if ( iCustom(NULL,0,"!SuperTrend cci (arrows + alerts + candles)",60,"Close price",60,"Display line(s)",true,LimeGreen,Orange,1,LimeGreen,Orange,3,Linen,Green,Crimson,8,Linen,Lime,Orange,4,false,false,false,false,false,false,"alert2.wav",true,2,2,"Up in a circle type arrow","Down in a circle type arrow",0.5,0.5,LimeGreen,Orange,5,1) < 9999999 &&
        iCustom(NULL,0,"!SuperTrend cci (arrows + alerts + candles)",60,"Close price",60,"Display line(s)",true,LimeGreen,Orange,1,LimeGreen,Orange,3,Linen,Green,Crimson,8,Linen,Lime,Orange,4,false,false,false,false,false,false,"alert2.wav",true,2,2,"Up in a circle type arrow","Down in a circle type arrow",0.5,0.5,LimeGreen,Orange,5,2) > 9999999 ){
            SuperTrend=1;
            }
Thanks in advance to people.
One thing i don't understand is what is the <> 9999999? Never seen that before.

Well MrTools - I don't have your skill but I noticed that when that particular buffer value goes 'blank' in the data window that it isn't actually zero, but seems to be something like 'infinity' ie. A massive number, So it either has a value of the super trend line or this massive number...... It seems to work, but just this memory leak is a pain..

Don't worry not questioning your skill at all, just am always learning, was wondering what that was. Might recheck you iCustom calls also the main trend buffer for that is #17 and if = 1 upTrend and =-1 dnTrend.

Oh that's good to know, thanks MrTools, will take a look at that and see if it improves things. Appreciate your time.

For anybody that might be interested at a later date, I resolved the memory leak with replacing the code earlier in the thread with the code below and calling the iCustom as an Integer. If I am honest - I have only a little understanding as to why that may have fixed the problem - but it may help somebody else down the line. Thanks again for the pointers @Mrtools.

Code: Select all

   int SupTrendNew = iCustom(NULL,0,"!SuperTrend cci (arrows + alerts + candles)",60,"Close price",60,"Display line(s)",true,LimeGreen,Orange,1,LimeGreen,Orange,3,Linen,Green,Crimson,8,Linen,Lime,Orange,4,false,false,false,false,false,false,"alert2.wav",true,2,2,"Up in a circle type arrow","Down in a circle type arrow",0.5,0.5,LimeGreen,Orange,17,1);
   int SupTrendOld = iCustom(NULL,0,"!SuperTrend cci (arrows + alerts + candles)",60,"Close price",60,"Display line(s)",true,LimeGreen,Orange,1,LimeGreen,Orange,3,Linen,Green,Crimson,8,Linen,Lime,Orange,4,false,false,false,false,false,false,"alert2.wav",true,2,2,"Up in a circle type arrow","Down in a circle type arrow",0.5,0.5,LimeGreen,Orange,17,2); 
  
   
   if (SupTrendNew==1 && SupTrendOld==-1){SuperTrend=1;}
   if (SupTrendNew==-1 && SupTrendOld==1){SuperTrend=0;}
EDIT: Further testing and it hasn't fixed - continuing to research.
