Manish Hathiramani, technical analyst with Deen Dayal Investments said: "The index continues to remain weak and any rally up can be used to short this market. 10,900-10,950 is a support range for the market so traders can book profits at the current juncture and use any opportunity to short the October series futures contract at higher levels for a target of 10,750. The resistance on the upside is at 11,300." /IANS
