'A' a short signal
The commercials are at a maximum short position (lowest in three years) and there had been a very high acceleration of shorting in the previous six weeks (80% at the green line at the bottom). A short signal occurred on July 25, 2013, after the previous bullish trend was broken. Holding this short position until the trend ended on October 31, 2013, would have yielded a gain of $3.660 per contract.
'B' a long signal
The commericals are at a high long position of a bit under 80% and the commercials had accelerated their buying to an extremely high level (about 70% in the green line at the bottom). Shortly after the bearish trend ended, there was a short entry signal on June 23, 2014. Holding that position until the bearish trend ended on November 19, 2014 would have yielded a gain of $3,773 per contract.
