Canadian Solar $CSIQ has been in a choppy downtrend since its all-time-high in 2014, at a share price just above $44. After finding support around 10.25 in late 2016, CSIQ consolidated in 2017 rallied above this "price bottom" in the second half of the year. In early 2018 so far, price action is signaling a possible bearish continuation.CSIQ Weekly Chart(click to enlarge)Flag Pattern:- As noted before, CSIQ has been in consolidation mode since late 2016. - More than a year later, we can see that a flat market turned into a rising channel. - Relative to the long-term, this rising channel could be simply flag pattern.Breakout:- While not very clear on the weekly chart, the bearish breakout is more apparent on the daily chart below.- Now, even though price did break below a rising trendline, there should be a couple of more conditions that would confirm the bearish intent of the market. 1) Price should hold under 17.50. A break above would revive the bullish reversal scenario.2) Price should be able to break below 15. 15 is a common support pivot, like a last line of defense for the bullish scenario.- A break below 15 would open up the 2017 low around 11 and possibly even the psychological level of 10. - A break back above 17.50 on the other hand opens the 19.00, 20.00 area and strengthens the bullish scenario for the year.
