No spoon feeding here
You don't need static variables for that. Depending on how much data you have, it can be stored directly in the formula, or it can be imported as artificial ticker or ...dozens of different ways....You can place your data in your formula. You can have different data sets for different symbols and use if-else or switch to pick correct one.
n = Name();
switch( n )
case "SBIN": data1 = 1.62;
data2 = 2.62;
data1 = 3.62;
data2 = 4.62;
