Target 7.5k - 9.1k (Weekly chart, large green box, weekly OB), also most recent swing low.
On a more refined note I see 2 zones where the corn might bounce.
1 (red box): Daily OB, 8.9-9.3k
2 (green box inside a green box): Daily OB in a weekly OB, 7700-8100
Then proceed for the next wave of bullishness.
