HK50 possibly break out the range?

Yesterday HK50 started off with some ranging candles but finally able to break above toward the end of the session. Today, depends how the first 15 mins candle open, I can see a continuation toward the upside as long as it can close above 16843.

For sell, since it is starting to form a bullish trend from a 4 hour time frame, I will only consider sell once it forms a lower high and lower low toward the 16379 level.
