US MIDDAY: wheat and corn down; soya up

Corn and wheat futures on the Chicago Board of Trade were choppy early on Tuesday and volume was light amid uncertainty ahead of this week's meeting of the US Federal Reserve and Tuesday's US elections, traders said. Soyabeans were lower as profit-taking and improving weather conditions in South America offset early support.

-- December wheat up 1/2 cent at $7.03 a bushel.
-- December corn up 1/4 cent at $5.77-1/2 a bushel.
