Example 1: Quantifying buyer exhaustion
On a micro index, price prints a swing high at 100.0 where cumulative delta reads plus 12,000. After a pullback it grinds to a new high of 101.0, but cumulative delta only reaches plus 8,000. Price is one point higher while net aggressive buying has fallen by 4,000 contracts: classic exhaustion, with passive sellers absorbing the bids. The plan is to short the failure back below 100.0, stop above 101.0, first target the session VWAP or nearest high-volume node below.
