Could easily be a breakaway gap on good news!

Seagull will clarify I'm sure

...from investopedia:

"A breakaway gap shows decisive movement out of a range or other chart pattern. These types of gaps are commonly associated with heavy volume, showing the strong conviction of the breakaway. These types of gaps are most commonly associated with major news events, or earnings announcements in individual stocks, which rapidly change investor sentiment.

Breakaway gaps don't tend to fill, or at least not for a long time. Instead, the price tends to run in the same direction as the breakway for some time after. The times when breakaway gaps do fill, the breakout direction usually prevails. The price may move back to where the gap started, fooling traders into thinking the gap was a false breakout, but then the price usually keeps moving in the breakaway direction."
