Playing a Quality Setup; Chess Moves

I just went long CRTO at $45.59 with a protective stop-loss below $43, looking to swing trade a breakout in this bullish technical setup which we have been looking at in recent weeks. This position amounts to roughly 4% of my portfolio capital. 

CRTO is a French internet firm which has shown signs of being under accumulation of late, gauging the volume pattern on the daily chart, below. 

In addition, note the tight basing pattern this week, giving us a bull flag over base long setup. 

If the broad market runs into trouble then I expect even quality breakout plays like this one to struggle. But, for now, I am trading what I see.
