September soft red winter wheat futures (ZWU25) present a buying opportunity on more price strength. 

See on the daily bar chart for September soft red winter wheat futures that prices have rebounded from the May low and recent price action has formed a bullish head-and-shoulders bottom reversal pattern. See, too, at the bottom of the chart that the moving average convergence divergence (MACD) indicator is also in a bullish mode as the red MACD line is above the blue trigger line and both lines are trending up.

Fundamentally, U.S. winter and spring wheat (KWN25) growing conditions over the past few months have not been ideal. This includes too much rain in hard red winter wheat regions the past couple weeks, which may reduce the quality of the crop. There have also been adverse weather conditions in Asian and European wheat regions the past few months. The recent slide in the U.S. Dollar Index ($DXY) is also a price-friendly development for U.S. wheat futures markets. Most grain is priced in U.S. dollars on the world trade markets. A depreciating greenback makes U.S. wheat more price-competitive on the world trade markets.

A move in September wheat futures prices above chart resistance at $5.60 would become a buying opportunity. The upside price objective would be $6.25, or above. Technical support, for which to place a protective sell stop just below, is located at $5.40.

IMPORTANT NOTE: I am not a futures broker and do not manage any trading accounts other than my own personal account. It is my goal to point out to you potential trading opportunities. However, it is up to you to: (1) decide when and if you want to initiate any trades and (2) determine the size of any trades you may initiate. Any trades I discuss are hypothetical in nature.

Here is what the Commodity Futures Trading Commission (CFTC) has said about futures trading (and I agree 100%): 

Trading commodity futures and options is not for everyone. IT IS A VOLATILE, COMPLEX AND RISKY BUSINESS. Before you invest any money in futures or options contracts, you should consider your financial experience, goals and financial resources, and know how much you can afford to lose above and beyond your initial payment to a broker. You should understand commodity futures and options contracts and your obligations in entering into those contracts. You should understand your exposure to risk and other aspects of trading by thoroughly reviewing the risk disclosure documents your broker is required to give you.
