Oct 5 (Reuters) - Copper prices were on track for a fourth straight session of declines, pressured by rising inventories, but trading volumes were tepid as top consumer China is on holiday.
Three-month copper on the London Metal Exchange was down 0.2% to $7,935 per metric ton by 0603 GMT, aluminium declined 0.1% to $2,243.50, nickel shed 0.2% to 18,695, while zinc rose 0.1% to $2,495.
LME inventories
"It's discount hunters but there was not enough volume... so price is still fragile and could break anytime," said a metals trader.
LME copper rose as much as 0.4% earlier in the session.
LME lead was almost flat at $2,118 a ton and tin rose 1% to $24,170.
