Soft Soybeans, Corn

The two charts shown at the top of this post are 3 minute charts of corn and soybeans. They are decidedly bearish today, but the bearishness lacks strong conviction. This is understandable, given the strong fundamentals for continued global demand for grains. However, note also the strong selling on the daily soybean chart at the bottom.

In these two charts, the Bollinger Bands are very important. The Bollinger Bands on the soybean chart are forming a "bubble" pattern, and the Bollinger Bands on the corn chart have formed a "parrallels" pattern, per Philippe Cahen in his book, Analyse Technique et Volatilite (yes, written in French). Both are profitable, but the bubble pattern tends to burn out more quickly and be less profitable, whereas the parralels pattern tends to extend itself over a longer period and be more profitable in the long run. Interestingly, a series of bubble patterns on a shorter-term chart will often form a parallels pattern on a longer-term chart.

Soybeans Daily Chart

The two primary indicators that I look for in deciding whether to go long or short are a crossover of the Exponential Moving Average, and a downturn in the Klinger Volume indicator that crosses above or below its moving average. Both of these conditions are showing right now on the daily soybean chart, shown here below. However, today hasn't closed yet, so until this occurs, a bearish trend in soybeans has not been confirmed. The bulls could easily step in and drive prices higher, perhaps even reaching a higher close today. Even if this happens, the bullish momentum on the longer-term charts is showing signs of waning, and exhaustion appears to be in the cards (see daily chart below). This has been a great bull run!

Most likely, at the end of a very strong trend, we are more likely to see a consolidation of prices at a fairly high level, rather than a complete reversal. Even if a consolidation occurs and a trading range sets in, this sets up my favorite trading conditions as a swing trader. Further, after a consolidation period of several weeks or even months, another break-out could occur and prices could move still higher.
