Corn headed for a retest of good support at 424/423 as I write but longs need stops below 421. A break lower targets 416/415 then support at 413/412. Try longs with stops below 410.
Minor resistance at 430/431 but above here re-targets 435/436 then the 2 day highs at 438/439. Bulls are starting to struggle in severely overbought conditions but if we continue higher look for 441/442 then 445.
