There are a few variations of this pattern, but most of the times it looks like a small double bottom / double top pattern on the chart. (colibritrader.com)
Although it is normally called support line in double top patterns, I prefer calling it neckline as in head - and - shoulders pattern. (earnforex.com)
So, there are still two possible future scenarios - bearish that will lead us below February low following trend line breakdown, and the bullish one in a form of medium - term double top pattern or breakout towards 3,000 mark. (futuresmag.com)
