The weekly chart shows a bullish divergence, but it is a weird one, I wouldn't count this chart as terribly bullish, and I would not be surprised to see Corn wiggle a bit more close to the current levels. Anyway, a bullish divergence makes it worth placing a bet, but as I said, not the most bullish divergence I've ever seen
The daily chart also shows long term bullish divergences on MACD lines, histogram and Force Index. Taken by themselves, I would say that the daily looks more bullish than the weekly, so that doesn't really convince me a long term rally is coming. As I said, it is worth a bet
