That gap up a few days ago has proved to be good support. I haven't been able to find any great detailed information on gap ups and their significance, or whether they then turn into support and resistance lines, and where they should then be. Anyone else have a better understanding on this?
The only info I can relate to it is that the move was either a breakaway or continuation gap:
A continuation gap forms in the middle of a move and in the same direction as the current move. These gaps signal a continuation of the preceding trend and can mark good entry points. After a short or intermediate advance, a continuation up gap is usually considered bullish and signals a renewal of the uptrend.
A Breakaway gaps signal a potential change in trend and are especially significant when accompanied by an increase in volume. A bullish breakaway gap forms when a security gaps up after an extended decline. Bullish breakaway gaps can also occur after an extended base or consolidation period.
