CGC: 
CGC had a long historical tracking record of negative return on Short flag.
And that means it usually bounced back up rather than showing further weakness.
However success of Short flag indicates further down trend.

CRON:
The correction was overdue so this was kind of expected and that was the reason why I was avoiding CRON trading over CGC.

Let's review the main Chart:

CRON's next down cell is at 16.46. That is almost 20% down from the current level.
The gap may be filled.
But today's dip was caused by Jefferies as they initiated the stock with under perform rating.

CGS's next down cell is at 40.13 and that is about 7% down from the current level.
So this one seems more comfortable than CRON.

I would avoid CRON for a while but would consider to buy CGC below 41.

HVBTF: I would buy to open LT position at or below 0.33.
