Offer Entailed Price
The entailed price of a specific offer in an offer list is wants/gives. It is the unit price that a taker must pay, when taking that offer.
example
If a maker has posted an offer with wants = 1 WETH and gives = 2 925.26 DAI, then the entailed price of that offer is 1/2925.26 = ~0.00034185 wETH per DAI. That means that a taker must give ~0.00034185 wETH per DAI received.
