@crytotango, Think about it as a ladder. Its safe if all the pegs are there, but take out a few and when you jump there is a greater probability of falling because you don't have the pegs. The gap for DIS is from $126 to $118 (roughly). I would say 85-90% of the time gaps fill at least 50%-100%. A 50% fill would be a drop to $122 roughly. The bears will take over because there is no volume support at levels below $126, and, going back to the ladder analogy, the bulls don't really mind the gap fill because it makes the ladder safer to climb (there is less of a chance of a major drop in the stock in the future at the gap price levels). Look at any stock and I can almost guaranty if you see a gap you will also see the stock filling that gap at some point in time.
Probably confused more than helped but let me know if that makes sense
