That's clearly a shooting star...gap up, tail at least divisible by 3 times the real body....a topping formation. this has shown on a few plays...if verified by a lower high next session these could retrace back to breakout levels to retest........now on bullish senarios they have been more shots across the bow stating basically that a top is near and the stock trades higher and then falls...but as a rule of thumb that is a perfect topping canclle....which would fit with a shake in stocks....
