Title: Fractional shares order execution methods
IPC: G06Q40/04
Filed: 2022-06-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for executing a notional-based buy orders of securities on a real-time basis. 
     SOLUTION: In a quantity-based and notional-based order execution system 100, a processing unit receives a notional-based buy order having a first amount from a first communication unit of a first participant. It receives a first estimated fractional share component comprised of a calculated quantity, and provides a first queue with the fractional share component. The first queue processes the fraction share component by a first-in first-out system. When the fractional share component arrives at the head of the first queue, the quantity is recalculated in accordance with the first amount and a real-time price. After unit fractional share buy or sell estimated by a notional-based buy order is executed, a second estimated fractional share component comprised of the recalculated quantity is provided to a second queue. Whether a sufficient quantity of fractional shares is stored in a fractional share database is determined, and if the sufficient quantity is stored, buying fractional shares from the fractional share database is executed on the basis of a parameter applied by a user.
