The two-year chart indicates that the units hit a double top in May of 2013 that started a decline which lasted into December of that year. The move lower shaved more than $2.00 off the trading price. The units broke above the downtrend line in January of 2014 and have started a new advance that has broken above the 50– and 200-day moving averages. Also worth mentioning were the sell signals generated by the MACD and the RSI in May of 2013 and the buy signals in December.
