This can be expanded on as the chat develops, but the two main points are: 1)-bands-traders don't know enough about "bands" to trust their buy (you buy the lower 1/2, sell the upper 1/2) - you need to know you bought the lower 1/2 to "set and forget" it. Bands are moved systematically by MMs, if you know how to read them, you can see it. 2)-impatience, usually exacerbated because their position is to large a % of their overall capital to wait any further. If you downsize to 1/2, for example, once you're tired of the wait, then waited the same amount of time gave the first wait, you'd score the big gain with 50% of your original "over-sized" buy-better than missing out. Remember, "the wait" is the accumulation period of the pumper. Follow-ups welcome!
