'A' a long signal
The commercials are at a maximum short position (longest in three years) and their acceleration of trading activity over the previous six weeks is extremely high (above 80% in the green line at the botton). A long signal on February 15, 2013, soon after the previous bearish trend was broken and holding the long position until this bullish trend ended on March 15, 2013, would have yielded a gain of $1,650 per contract.
'B' a long signal
The commericals are at an almost maximum long position and the commercials' activity in the last six weeks has accelerated to an extremely high level (almost 80% in the green line at the bottom). Shortly after the bearish trend ended, there was a long entry signal on July 8, 2014. Holding that position until the bullish trend ended on March 18, 2015 would have yielded a gain of $14,680 per contract.
