LONDON SUGAR TRADES AT SESSION HIGHS BY MIDMORNING Raw sugar futures firmed to session highs by midmorning, securing gains from last night's basically steady close of 1.00 to 1.80 dlrs a tonne in a 166 lot volume. Shortcovering against an oversold situation continued to play a part in the extended rally with unsettled dollar rates versus sterling providing additional support. Recent and prospective whites buying in the world market was supportive but the raws section lacked feature, dealers said. India and Egypt bought white sugar this week while next week sees tenders by Pakistan, Greece and Syria, they said. May was at 154 dlrs from 152.80 asked last night. All London Daily prices rose two dlrs a tonne on tone. The Raws price was set at 150 dlrs Fob and 173 dlrs (107.50 stg) Cif. The Whites price was at 192 dlrs from 190 yesterday.
