When a market opens outside of the previous day's range and then auctions around the open, one's first impression is that there is no directional conviction present. In reality, the mere fact that the opening is beyond the previous day's range suggests that new other time frame activity has caused price to seek a higher or lower level. Given that the market has opened out of balance, there is a greater chance that directional conviction will develop than if the market had opened and auctioned within the range. An Open-Auction outside of range has the potential to be a big day, while an Open-Auction within value usually lacks conviction.

[...] In the large majority of cases, activity during any given day has direct and measurable implications on the following day. It is only on the relatively rare occasion when a market moves extremely out of balance that there is no correlation between two consecutive days. Understanding these implications enables a trader to more successfully visualize developing market activity.
The salient concept here is market balance. The relationship of the open to the previous day's value area and range gives valuable clues to the market's state of balance and what kind of risk/opportunity relationship to expect on a given trading day. In short, the greatest risk and opportunity arise when a market opens outside of the previous day's range. This indicates that the market is out of balance.
When a market opens out of balance, the potential for a dynamic move in either direction is high. Conversely, a market that opens and is accepted (auctions for at least one hour) within the previous day's value area embodies lower risk, but also less opportunity. The acceptance of price within the previous day's value area indicates balance, and therefore reduces the potential for a dynamic move.
