DDD Daily Chart(click to enlarge)Bearish Breakout:- Looking at the daily chart, we can see that price started to rally after ranging for much of the first half of 2018. - Price eventually pushed above the moving averages. - Recently, after failing to tag $22, price started to retreat. - As it was holding above $16, the general bullish outlook was still intact.- However, after some initial support at $16, we can see that price fell below it sharply during the 10/31 session (following the 10/30 after-market earnings report). - This dip breaks below a key support/resistance pivot, a rising trendline, and the 200-day SMA.- Now, we should look a the $15-$16 area as resistance.- If price holds under this area, there is also downside to the $10 mark or lower. - We can see on the weekly chart, that the overall trend has been flat since 2016, but bearish before that.- Under this mode, we should probably avoid DDD until it gets into that support area between $6.30 and $8.10 (refer to the weekly chart below.)DDD Weekly Chart(click to enlarge)
