Dutch Bid Amount Computation

---

The bid amount in a Dutch auction is automatically computed over the duration of the auction using the following equation:

BA = ASP - [(CT - AST) / ATI] * BI

subject to the Auction Terminal Price (ATP) where:

Abbr.	Property	Maps to S_AUC_ITEM property...	Description
BA	Bid Amount	N/A	Automatically calculated by the system by using the above equation.
ASP	Auction Start Price	START_BID_AMT	The initial amount a lister will accept for a given item.
CT	Current Time	N/A	The current date and time at which a bid is made.
AST	Auction Start Time	AUCTION_START_DATE	The date and time at which an auction is available for bidding.
ATI	Dutch Time Period Minutes	DUTCH_TM_PRD_MINS	The time interval (in seconds) between price increments.
ATP	Dutch Minimum Price Amount	DUTCH_MIN_PRI_AMT	The minimum amount a lister will accept for an item.

If the bid increment (BI) is positive, then the price decreases; otherwise, the price increases. The bid amount is subject to two constraints:

Availability of the items sold (for example, positive quantity)
Bid amount is greater than the auction terminal price (case of BI > 0)
