Soccer just saw your post. I dont know Altium, from the weekly its in an uptrend but id have to do some work on the chart to form a view.
As for the daily I mostly ignore that chart as noise as its very difficult to pick the smaller fluctuations like you seem to be trying to do. Nevertheless if I wanted to buy a stock and saw a daily gap like this Id probably wait for the pullback to get set. Most fill, depends on what drove it though, I assume results and some announcement. I notice they go ex-dividend tommorrow of 12c, which will be holding it up today.
If me I'd sit back and let it settle first rather than buy into this current volatility.
