What counts as a genuine delta divergence at a swing low?

Price has to make a new low compared to the prior swing low, while the net buy/sell delta at the new low is higher (less negative) than it was at the prior low, showing less aggressive selling drove the second low.

What does it mean if price and delta both make new lows together?

That is delta confirming the move rather than diverging from it. Selling was as aggressive or more aggressive on the second low, which is the specific condition that invalidates a Delta Divergence Bottom setup.

Delta Divergence Bottom & Top Checker

Enter Both Swing Points

Pick whether you're checking two swing lows or two swing highs, then enter the price and the net buy/sell delta (aggressive buy volume minus aggressive sell volume) at each one. A negative delta means selling dominated that swing; a positive delta means buying did.

How this is calculated

For two swing lows, a genuine bullish divergence requires price to make a new low (Swing 2 price below Swing 1 price) while delta does not (Swing 2 delta higher than Swing 1 delta, meaning less negative or less aggressive selling drove the second low).
For two swing highs, a genuine bearish divergence requires price to make a new high (Swing 2 price above Swing 1 price) while delta does not (Swing 2 delta lower than Swing 1 delta, meaning less positive or less aggressive buying drove the second high).
If price does not actually make a new extreme against the first swing point, this tool tells you the setup does not apply yet rather than forcing a divergence read on two points that were not comparable to begin with.
If price makes a new extreme and delta moves the same way (a new low with a new low, or a new high with a new high), that is delta confirming the move, not diverging from it, which is the specific invalidation condition both Delta Divergence setups in this pack are built around.
The aggression change shown is the percent difference between the two deltas' magnitudes, a rough read on how much less (or more) aggressive the tape was on the second swing, not a probability of the reversal working.
