I'm suspecting that September Wheat has turned the corner and is now setting up for a significant rally to either 50% or 61.8% retracement. (Note in the chart how nicely a resistance area fits between these two retracements.) Once again, we see that RSI has (today) bounced off of a long-term trend line. I've seen this type of behavior occur again and again in charts of many commodities, the reason being, I think, that price lines of support and resistance coincide with RSI trend lines. What we seem to have before us as of today (Tuesday) is wheat currently boxed in between the 6/30 low and close. The corresponding RSI triangle indicates to me that a breakout either up or down will occur within the next day or two. My bias toward the upside is due to the significant recent move up after a month-long steep downtrend. I don't think my bias is in the category of wishful bottom fishing, because RSI's recent behavior (for 5 days now) indicates (to me) a bullish change in sentiment. For confirmation, I'll be looking for an upward move through the 6/30 close (540.75).
