# Passing a metrics to StaticVarGenerateRanks

Hi I am having a problem with passing my metrics to StaticVarGenerateRanks.

Part of my code (my metrics, is just n example to shown that I need a loop to calculate it):

``````//This sets the Static Metrics
for (y=ymin; y<=ymax; y++)
{ 	StaticVarSet( "Rocs"+Name() + y, IIf( var == y, Rocs, 0 ),persistent =True );// ROC at each  variable Var
count= Cum(IIF(var ==y AND NumOfBars>0, 1,0)) ;// Number of occurrency per each case
StaticVarSet("Count"+Name()+y, count,persistent =True);
for( i = 1; i < BarCount; i++ )
{ if (var[i]==y AND NumOfBars[i]>=1+lag)
eq[i]=eq[i-1] *(1+Rocs[i]/100);
else
eq[i]= eq[i-1];
}
StaticVarSet("EQ"+Name()+y, eq,persistent =True);
geteq = StaticVarGet( "EQ"+Name()+y);
FValueEQ= LastValue(ValueWhen (fbr==1,geteq,1));
LValueEQ= geteq;
getcount=StaticVarGet("Count"+Name()+y);
StaticVarSet( "CAR"+Name()+y, CAR,persistent =True);
GETCAR=StaticVarGet( "CAR"+Name()+y);
for (i=1; i<BarCount; i++)
{ if(refvar[i]==y)
{ AGGCAR[i]=  GETCAR[i];
StaticVarSet( "AGGCAR"+Name(), AGGCAR,persistent =True);
}
}
}
``````

generates AGGCAR and stores it in a Static Variable which should then be used with StaticVarGenerateRanks.

My problem is that AGGCAR is not passes to StaticVarGenerateRanks because StaticVarGenerateRanks is computed if ( Status( "stocknum" ) == 0 )

When I run explorer (see attached file) AGGCAR is calculated correctly (AGGCAR column) but not passed to the StaticVarGenerateRanks calculation (RankMet column) . If I run the exploration twice I can see that (RankMet column) gets the right value from AGGCAR.
Rotational_with_rank_light_v1.afl (14.3 KB)

I guess the problem lays with the order of execution, basically I suspect that AGGCAR is calculated at each bar for each ticker, while StaticVarGenerateRanks (RankMet column) is generated when Status( "stocknum" ) == 0 ) only, therefore it misses all the AGGCAR because at Status( "stocknum" ) == 0 ) RankMet is not know for all tickers > 0.

I ve been trying to solve this issue for a while and cannot find a solution.

Any help would be very welcome.

@jbenfeld, I don't have time to review all of your code in detail, but I think you are on the right track with your observation that the problem is tied to order of execution. One potential way to solve this problem would be to run a "preliminary exploration" that generates the AGGCAR values and stores them in Static Variables. At the conclusion of the preliminary exploration, do not remove your static vars.

Immediately after running the preliminary exploration, run the exploration or back test that performs the `StaticVarGenerateRanks()` logic inside the "`if ( Status( "stocknum" ) == 0 )`" block. All of your Static Vars should still be defined from the running of the preliminary exploration.

that is exactly the problem I am facing an stuck in.

I CAN"T run a "preliminary exploration" that generates the AGGCAR (I am not capable of, due to my limited coding skills)

I do NOT expect the solution from the forum, but if anyone has an hint, than I can wortk of it.
e.g. would #include work? because I have tried it and didn't for me.

@jbenfeld perhaps my terminology was confusing. When I said "preliminary exploration", I simply meant a regular exploration that you will need to run before you execute the code with the `StaticVarGenerateRanks`. So as a rough, untested outline, you could do something like this:

``````idExplore = Param("Explore ID", 1, 1, 2, 1);
...
if (idExplore == 1)
{
// Your logic to generate AGGCAR and save static vars using StaticVarSet()
}
else if (idExplore == 2)
{
// Your logic to use StaticVarGet() and call StaticVarGenerateRanks()
}

Run your code once with idExplore set to 1, and then run it again with idExplore set to 2. Alternatively you could create  two separate AFL files, and run them sequentially, perhaps even using an AmiBroker batch file if you wanted the sequential execution to be more automatic. There are lots of ways to solve the problem.``````

Thanks a lot this looks a really good starting point.
Thanks for you time to answer my post.

I think I managed to solve (with someonelse help) this issue by running the loop at the first simbol as shown in the code below and in the attached file. Most likely is possible to to have one instance of

``````if ( Status( "stocknum" ) == 0 )
``````

but I had to write two of them, but this is is enought for me. Not perfect but is working.

Everything works fine. You do not need any pre-explorations. You just need to place the code that calculates ranks BEFORE the code that uses them.
The formula is executed sequentially from top to bottom. At the time when you call StaticVarGenerateRanks all ranks are calculated in-place and READY to be used as soon as the NEXT line in the code.

``````if ( Status( "stocknum" ) == 0 )
{
...
StaticVarGenerateRanks(...);

// ranks are ready to be used at that line and below (on first symbol)
// obviously for all other symbols ranks will be already in static variables from the very beginning
}
``````

It does not really matter how many `Status("stocknum")` calls you have.

As soon as AmiBroker sees at least one such line it would execute the code for FIRST symbol only in single thread and only when it is finished, it will start parallel (multithread) execution of remaining symbols. This is specifically designed so, to guarantee that things like ranking or any kind of "first symbol only" processing are done BEFORE execution of all the other symbols. The decision to run it that way is done BEFORE execution. AmIBroker simply searches for such string in ENTIRE code BEFORE your code is run. So it does not really matter how many lines like that are found. If there is at least one, it will postpone processing of other symbols until first one is complete.
