All you gap filling morons need to understand that stuff is pure nonsense, gaps never have to fill and unless there is no news for a long time and a subsequent slow bleed it never will fill. It is the stupidest theory on the planet, with no technical basis and no fundamental reason to ever have to happen, sure it happens a lot with small caps only due to their volatile nature, large price swings and general sideways over large time period. Every other price point is also passed along the way to it's intermediate top or bottom. Stocks go up and down due to supply and demand changes each day and over time, that is the only reason for price changes, WAKE UP!!!!!!!!!
That's one of my pet peeves as well. However, if the market was truly a random entity that perfectly priced the value of assets, technical indicators shouldn't mean a whole lot either. The market is ultimately driven by human behavior, algorithms included. If indicators, gaps, etc. have any value, it's only because enough traders act on it and give them meaning. It becomes a "group think", self-fulfilling prophecy, for lack of a better way of putting it.
The only reason technical indicators are of any value, which gaps are not, is that they show the history of supply and demand and potential trends, that can change at any time, but are probabilistic in nature. That is why they at least have some meaning and why patterns repeat a certain percentage of the time.
To the other poster piccaso, the point is that if there is a buyout in progress, it will never go back to fill the gap up on today's daily chart. Gap filling is a joke for child analysts.
