Impossible to call stored AlgoVar2 variables.

Impossible to call stored AlgoVar2 variables. - 03/25/19 19:09

Hello,

I'm able to define AlgoVar2 variables, but unlike the AlgoVar variables, they return 0 after I call them from a .trd file. Did I made a mistake in my code? I also tried to store the AlgoVar2 variables to a second .trd file, but no luck.
Thanks for any feedback!

Code:

function run()
    {
    If(Bar >= 1) 
	{
      //Run this code only once with 1 == 1
	if(1 == 2)
	    {    
  	    AlgoVar[0] = 1;
	    AlgoVar[1] = 2;
	    AlgoVar[2] = 3;
	    AlgoVar[3] = 4;
	    AlgoVar[4] = 5;
	    AlgoVar[5] = 6;
	    AlgoVar[6] = 7;
	    AlgoVar[7] = 8;		
	    AlgoVar2[0] = 9;
	    AlgoVar2[1] = 10;
	    AlgoVar2[2] = 11;
	    AlgoVar2[3] = 12;
	    AlgoVar2[4] = 13;
	    AlgoVar2[5] = 14;
	    AlgoVar2[6] = 15;
	    AlgoVar2[7] = 16;
	    saveStatus("Log\a.trd");
	    }
		
	loadStatus("Log\a.trd");
	printf("n %.0f", AlgoVar[0]);	
	printf("n %.0f", AlgoVar[1]);	
	printf("n %.0f", AlgoVar[2]);
	printf("n %.0f", AlgoVar[3]);
	printf("n %.0f", AlgoVar[4]);
	printf("n %.0f", AlgoVar[5]);
	printf("n %.0f", AlgoVar[6]);
	printf("n %.0f", AlgoVar[7]);
	printf("n %.0f", AlgoVar2[0]);
	printf("n %.0f", AlgoVar2[1]);
	printf("n %.0f", AlgoVar2[2]);
	printf("n %.0f", AlgoVar2[3]);
	printf("n %.0f", AlgoVar2[4]);
	printf("n %.0f", AlgoVar2[5]);
	printf("n %.0f", AlgoVar2[6]);
	printf("n %.0f", AlgoVar2[7]);
		
	quit();
        }
    }

if(1 == 2) automatically means if(false). This means the next code block will be ignored.

Hello Andrew,

I did that on purpose. My goal is to call these variables, once they are stored. This works fine for the AlgoVar, but not for the AlgoVar2 variables and I wonder why.

OK, but it's not clear what you are trying to do. Can you split it into two separate scripts for clarity?

OK, first I define the AlgoVar and AlgoVar2 variables and store them to a .trd file:

Code:

function run()
          {
	  if(Bar >= 1) 
	      {
	      AlgoVar[0] = 1;
	      AlgoVar[1] = 2;
     	      AlgoVar[2] = 3;
	      AlgoVar[3] = 4;
	      AlgoVar[4] = 5;
	      AlgoVar[5] = 6;
	      AlgoVar[6] = 7;
	      AlgoVar[7] = 8;		
	      AlgoVar2[0] = 9;
	      AlgoVar2[1] = 10;
	      AlgoVar2[2] = 11;
	      AlgoVar2[3] = 12;
	      AlgoVar2[4] = 13;
	      AlgoVar2[5] = 14;
	      AlgoVar2[6] = 15;
	      AlgoVar2[7] = 16;
	      saveStatus("Log\a.trd");	
			
	      quit();
	      }
	  }

Then I call these variables and only the AlgoVar variables return their value.

Code:

function run()
    {
    if(Bar >= 1) 
        {
        loadStatus("Log\a.trd");
        printf("n %.0f", AlgoVar[0]);	
        printf("n %.0f", AlgoVar[1]);	
        printf("n %.0f", AlgoVar[2]);
        printf("n %.0f", AlgoVar[3]);
        printf("n %.0f", AlgoVar[4]);
        printf("n %.0f", AlgoVar[5]);
        printf("n %.0f", AlgoVar[6]);
        printf("n %.0f", AlgoVar[7]);
        printf("n %.0f", AlgoVar2[0]);
        printf("n %.0f", AlgoVar2[1]);
        printf("n %.0f", AlgoVar2[2]);
        printf("n %.0f", AlgoVar2[3]);
        printf("n %.0f", AlgoVar2[4]);
        printf("n %.0f", AlgoVar2[5]);
        printf("n %.0f", AlgoVar2[6]);
        printf("n %.0f", AlgoVar2[7]);

        quit();	
        }
    }

It looks like the AlgoVar2 variables don't get saved or loaded at all.

Zorro feature not yet implemented?

Yes, according to the manual only the AlgoVars are saved.

What do you mean with AlgoVars? Only AlgoVar[] or AlgoVar[] + AlgoVar2[]?

I thought that there might be a limit to the number of variables a .trd file can store, so I saved the AlgoVar2 vars to a second file, but no luck.

Ah interesting, but then what's the use of AlgoVar2 in this context?

My bad, I meant multiple AlgoVar variables.

I meant only AlgoVars, not AlgoVars2. Saving them too could of course be implemented, but I believe the orginal intention was to leave AlgoVars2 initialized to zero so that they can be used as counters or similar.

Why not have a separate SaveMode flag, like SV_ALGOVARS2?

Or increase the number of AlgoVar variables. 8 is pretty limited for a multi-portfolio model. Anyway, it's not a big deal since there are multiple ways to store values.

This would address this:

A Zorro version in use exactly one year ago saved/loaded all AlgoVars.
My script relied on this for state recovery, so I spent enough time to verify it does work.

It would be great if this came back and worked as expected.

nooooooooooo I can only store 7 trade for each Algo/Aset. In testing obviously this fact did not emerged...

You can save any kind of binary data to disk, by the way. It's not terribly difficult.

Agreed and I already found a solution in the meantime. The AlgoVar feature however is a very simple way to store and call values between Zorro sessions.

Same situation for me. Misunderstood what reported in the manual. Now I have to switch to save data on file and is not trivial...

Saving the Algovars2 together with the Algovars would break systems that are using them, so we can't do that directly. But a flag SV_ALGOVARS2 is no problem. Even better would be a future feature to save certain series or memory areas.
