Jeddingen Divergence seems to successfully predict reversals on the Corn (4H timeframe). The past 4 signals where very accurate, this accuracy might continue.
There is a current bullish jeddingen divergence (divergence of price vs. momentum) and a little pullback, so it would be a good time to enter the trade.
Take profit on price crossing-up of the trendline or wait until price comes near to the resistance line.
