Short As long as no break out of Trend Channel

Updated
Air Liquide is at the top of a down facing trend channel. In the longterm the stock is a must buy for me. But for the next few weeks this is a short for me. Stop as soon as the trend channel is broken.
Note
stop loss. Not my best trade I have to admit. :D But maybe it is time for long now?
