October raw sugar was up 0.11 cent, or 1 percent, at 10.92 cents per lb by 1107 GMT, after climbing to a session high of 10.96.
Dealers pointed to chart-driven buying as speculators attempted to test resistance around the 10.93 cent mark.
Prices hit three-year lows this month before rebounding on short-covering, although momentum has petered out in recent sessions as prices ran into technical resistance.
тАЬWeтАЩre still in the recent range,тАЭ said one European dealer. тАЬBut some people feel there could be further improvement because of the weather issues weтАЩve seen.тАЭ
Focus has been on a prolonged dry spell in Europe and centre-south Brazil, although dealers said recent rains in the latter are expected to have helped relieve the drought.
тАЬWe desperately needed some rain, so that would have helped,тАЭ said one European dealer. тАЬBut (in CS Brazil) if you get rain this time of year, itтАЩs going to disrupt the harvest.тАЭ
