Wheat futures on the Chicago Board of Trade were higher at midsession on Tuesday, rising to one-month highs on technical short covering by funds, traders said.
There was little fundamental news to drive prices. But funds remained heavily net short, leaving the market open to a short-covering rally.
Buy-stops were hit when the spot March contract broke through chart resistance at last week's high of $3.26-3/4.
As of 11:30 am CST (1730 GMT), CBOT March wheat was up 5 cents at $3.28-1/4 per bushel after reaching $3.29. Deferred months were up 4 to 5-1/4 cents.
