i hear a lot about the gap being filled
and stocks gapping up with a positive announc.
but why does it have to get filled ?

any recommendations on articles relating to this would be great

It doesn't have to do anything, and it quite often doesn't get filled. In fact I'd go as far to say (at least with the types of stocks I follow) they are rarely filled. In my experience, if a spec stock gaps up strongly on a news announcement, it usually runs up very strongly, and rarely returns to the gap.

Comsec wont let people gap it up on many trades.. ie if only offer is 20% higher than current buyer they wont do the trade ... see some examples in BMY..
 
After seeing AEV do this,

my mind wandered back to filling the gap situations. I'm guessing that you would classify this as a break away gap then @tech/a

My thoughts now run in general onto how long it takes for gaps to get filled.
I would think that the more time after a break away gap up, the less likely to be filled. Will have to consider more on the timeframe scenarios. And then there's gap downs...??

Yes I would see it as a breakaway gap.

Some other positives are that it was on volume and the very next bar was on less volume but didn't retrace into the gap.
On the negative side, it hasn't traded above short-term resistance despite the large increase in volume indicating there is still
supply around at these levels. It's doing its darndest to exhaust the supply. Once achieved looks good.
