Barchart's opinion on MDMN, or any other stock for that matter, is meaningless, unless you desire to lose money by following their opinion.
Barchart issues strong (100%) buy signals after a run has already occurred and generally when a chart is looking toppy. Similarly, Barchart issues strong sell signals after a long period of selling or a pull back.
Anyone following the buy and sell "signals" of Barchart is doomed to buy high and sell low and that is why most people with knowledge of charting scoff at Barchart's opinions - whether they be bullish or bearish.
