Since the bulk of the liquid corn futures trading occurs in a short 4.75 hour session, I'd suggest the following for technical analysis of corn futures charts:
1. Look at Weekly, Daily, and Hourly charts primarily. You must select out only the best trending chart time-frame. And then exploit pull-backs against that time frame. Train your eyes to "see" the Dominant Trend - this makes for the most easy profit opportunity setups.
2. The Weekly corn futures chart appears to be forming a near Double Bottom formation - another excellent trading pattern that can be exploited. But - you must WAIT until the Double Bottom formation is clearly in place (and it may not even happen).
3. The Daily corn futures chart had a nice trending pattern recently but less so now.
If you must squint, stare, open eyes widely, use magnifying glasses, etc., chances are that time frame is NOT in a clearly trending mode - stay away from it!
Beware - don't forget - you must mark out contract rollover dates, and switch only to the most liquid corn futures contract month.
I've seen back-tested research on corn futures data - adjusted for rollover price gaps, etc. All not very good for real high-profit analysis in our experience.
Don't hesitate to post charts here on T2W - lots of expert technical analysis experts here!
But for me personally - I only am interested in technical trends/patterns that represent the most "easy pickings" by following the big money trends!
