NT crashes with this code without any reason.

[pstrusi]

Maybe not the most elegant solution but finally I've solved this issue:

simply, the dataseries variable cc, hh, and ll were substituted by these double variable a,b and c. So now I can perform the basic comparisons without any trouble a>b b>c a>c ...etc etc

Obviously the problem is when I wanted to construct a dataseries variable within other.

NT Support needs in here...

No, it doesn't work because it's the same, three conditions..it must be up to 2 cond.

if (     cc[0]>hh[0] 
   && cc[0]>ll[0] 
   && hh[0]>ll[0] )

Could be rewritten as:

if (      hh[0]>ll[0] 
   &&  cc[0]>hh[0] )

Right?

Another interesting note that I've founded with this issue:

If I just set two conditions ( of this type xx[0]>yy[0] && xx[0]>zz[0] ) instead of three or more same type or condition simultaneously, then the optimization goes perfect....so, could it be a memory-variable problem that I could address with a right initial configuration?

No idea

This might work then:

if (cc[0]>hh[0])
{
  if (cc[0]>ll[0])
  {
     if ( hh[0]>ll[0] ) 
     {	
         EnterLong(100000, "BUY");	
     }
   }
}

I don´t get any message, nor even in trace or log files...it totally crashes without messages, That´s why I can't solve it

Thanks Sledge,

That's in forex. I try to optimize it in the strategy analizer (backtesting)

I suspect it's a memory-variable issue not yet addressed by me.

I wait for more responses

It's always fun to post the screenshot of the error message. Draws more attention, since it is super big and usually has a lot of hidden calls in it. *assuming you are getting one.

Hi, I had no problems running the code here in Market Replay. Are you trying to run this in Strategy Analyzer, or Live, or Sim?

Market Replay did stop and cancel the strategy, because the 100,000 ES contracts is bigger than my Market Replay Account. 10 contracts worked fine. I'm not sure what you are buying 100,000 of, Penny stocks?

I'd add more print statements like I've done with your code, to find the exact line.

*edit-> Have you tried rebooting your machine?

Here is some sample output:

Hi ninjas,

This issue is driving me crazy. Everytime I try to run this apparently simple code, NT crashes. I really need your help. This is the core of this simple testing code:

An important note: the crashes just happens when I set the comparation:
cc[0]>hh[0] && cc[0]>ll[0] && hh[0]>ll[0]

and it goes just fine with this combinations:
cc[0]>1 && cc[0]>1 && hh[0]>1

WHY? and how can I solve this?

I appreciate your help as always
