March wheat opened 12 1/4 cents higher on the session at 628 1/4 and established an early range of 614 1/4 to 629 1/4. Funds were active buyers early in the session to drive the market sharply higher on the day and to a new 8-session peak. However, once the short-covering from fund traders dried up, the market pushed to slightly lower on the session into the mid-session. Tunisia bought 75,000 tonnes of durum wheat at their tender today. Deliveries on first notice day were 440 contracts.
