Here is another way to trade CORN using the ETF:CORN. This is a Stockcharts chart rather than a Qcharts chart. The price bars are what's called Elder Impulse bars in Green, Blue and Red. The colors are determined by the direction of the 13ema and for extra sensitivity the MACD Histogram needs to confirm a higher high than the previous day or the Green bar turns Blue. And if the 13ema turns down AND the Histogram has a lower low the bar turns Red. Watching the 'color pattern' is often a good heads up when a rally is ending or beginning. More erratic and volatile markets are not as smooth as normally trending markets regarding color patterns. Bottom line is this ETF on Corn can be traded in most any stock account just like any stock and trades without all the issues a futures market has. Note the CCI 20 indicator and the vertical lines marked that show recent lows. Nice indicator with some consistency in signals. Click link bottom left of post for chart:
