Create variable in private void ()

[no111]

Hello,

I've got this:

    for (int x = 1;   x < 3 ; x++)
            { 
                DoStuff(x);
            } 

Where x is barsinprogress (I added two symbols: SPY, DIA).

        private void DoStuff(int x )
{ 
    //in here i got two integers a, b;
  
} 

Now when the first symbol (loop x=1) is done, it has stored something in integer a and b.
Now the second symbol is on, DIA, but now it will overwrite something what is stored in a by SPY.

How can I overcome this? So that SPY and DIA have is own 'a' and 'b'. (I think, it should be in the loop i.e. It creats a1, b1, a2, b2 as integers/doubles, but how do I do that?)

Someone who has a suggestion for me?

Thanks

Hello no111,
You can create a List of your variable and store the values there.

Unfortunately its more of C# query and beyond what we could support.

Easiest way is to have 2 more integers, so that each set is separate and populated depending on the value of x.

private void DoStuff(int x )
{
if (x == 1) {//populate a1 and b1}
else if (x == 2) {//populate a2 and b2}
}

Thank you for an answer. My idea was to add more than 2 symbols, for example 10 ETF's so I can measure the performance of the strategy better (with combined results if you backtest a basket, you don't get a equity curve for example).

Any ideas for that?

You can use a bunch of suitably named variables or you can use Arrays to hold the two sets of values.
