On the subject of gaps:
In candlestick analysis once a window (gap) is closed it is closed forever and is not used again for support or resistance. Another factor such as a particular pattern may make the same price support or resistance, but it is a coincidence and not attributed to the window.
The rising window (gap) on 10/20 - 10/21, the bottom of which was 49.50, would not be considered support again since this window was closed on 11/21.
However, if you look closely there was another small window on 12/14 - 12/15 with a bottom at 52.14. Take note that the low of the recent weeks was at 52.15 confiirming the support of this window. Another point for the bulls.
