The gap matters because the open moved away from prior value

Gap levels show the price space between the prior close and the new session open. That gives you a simple map for whether the market is filling, rejecting, or accepting away from that zone.

Use the midpoint as balance context

The gap midpoint can help frame whether the session is treating the gap like a full rejection, a balanced test, or a partial fill that still leaves the opening move intact.

Pair the gap with participation

Gap behavior gets more useful when you also know whether the fill or rejection is happening with real activity. That is where relative volume or volume spikes help.
