1. A method implemented at least partially in a programmed computer for executing a securities order, the method comprising:
- receiving a market order to buy with a size that causes an imbalance;
executing a portion of the market order at an execution price, wherein the execution price is a best offer price;
changing a quote from fast to slow;
using the programmed computer to automatically calculate a remaining unexecuted size of the market order;
using the programmed computer to automatically set a new best bid price equal to the execution price;
using the programmed computer to automatically quote the unexecuted size of the market order at the new best bid price;
using the programmed computer to automatically quote a new best offer size as 100 shares; and
using the programmed computer to automatically quote the new best offer price as a gap price, wherein the gap price is the next even 50 cents greater than the new best bid price and creates a wider-than-normal spread between the quoted new best bid and new best offer, and the combination of gap price and 100 share new best offer size serves to draw in sellers.

Abstract
A large market order to buy is received causing an imbalance. A portion of the market order is executed at a best offer price. A quote is changed from fast to slow, and a remaining unexecuted size of the market order is calculated. The unexecuted size of the market order is quoted at the best offer price, and the best bid size is quoted as 100 shares. The best bid price is quoted as a gap price. In a similar fashion a large market order to sell results in a gap quote.
