How do I loop through all the active positions and get their individual information?

As the title says. How do I access individual position's information? The thought that comes to mind is looping through all of them and checking them one by one untill I find the one I want. But how do I do that?

If this was some other programming language I could do this but this doesn't work here because PositionGetSymbol(index) doesn't hold any information(?)

for (int i = 0; i < PositionsTotal(); i++) { 
        PositionGetSymbol(i).volume; //Would be i-th position's volume 
        PositionGetSymbol(i).price; //Would be i-th position's price and so on
}
