Do Stocks Need to Fill Gaps?
Importantly, gaps do not always fill. Traders should never assume that a gap will fill without understanding the reasons for the gap and monitoring trading activity around the gap Breakaway gaps often do not fill, or fill only partially since the broken support or resistance area serves as resistance or support during gap filling action.
Watching to see if BB and or Kchannel midlines hold as price support before I consider odds on next lower gap filling 14 and 14.43. Midlines are currently 16.89, which was tested so far today, and 16.54. I just watch steps and adjust my targets as necessary, taking no action until I see confirmation signals.
Just my individual way.
I have seen unfilled gaps many times in 30+ years of following stocks. Even in big name stocks. It is a consequence of computer action as well as having increased in this AI era IMO.
