Corn, wave 3 trade setting up 2 drop from 405'0-289'4

Corn is setting up for a Strong tk cross to the down side.
Wave 3 is lining up to prior support found back in 2009.
If the market can close below the 405 area I am very bearish
on corn and am looking for a target area near the 289 level preferably around the 290 (ROUND NUMBER)
