T/A = technical analysis
BB = Bollinger Bands. The bottom of the band is 0.4537 and top is 0.5888 so basically we need to break 0.6c for an up trend or breach 0.4c for a downtrend.
Just looked at it daily as I'm not trading DHR, unfortunately sitting in my portfolio at a loss probably for the next 1-2 years based on the lack of near term SP catalysts.
