dec corn update are we looking at the 4th wave up of the 5th wave?

Looking at Dec corn on the daily chart below with this last push down looks impulsive and possible finished just above my 336 call to finish a w3 of the 5th wave and a  Wave 4 higher now to target 466-475 maybe brewing.... as wave 2 was a simple deep zig zag.  Ill be watching for wave 4 to be a flat or some kind of shallow triangle correction. 

my second thought is that this a wave 2 but it appears to impulsive with no overlapping waves. holding long for now. Any questions or markets you would like me to take a look at please feel free to ask. commoditykid@gmail.com
