How the Metal Commodity (like Alu,zinc,lead etc.) prices are linked/dependent on LME ?

Basically, i want ot know how the prices pf the Base metal is set in india …is it purely on demand/supply in india or it depends on the LME as other commodity such as Crude,Gold,silver does.

If it is based on LME , can you please let me understand how the prices are calculated or arrived (as you have explained for Gold in earlier post)

Thanks

Sonu

Hi karthik,
I wanted the same kind of calculation for Metal Commodity… and do there prices is really dependent on LME exchange prices or is it simply based on local market factor i.e. demand/supply ?
