Abstract: Electronic peer-to-peer negotiations are provided which a user accesses via a web-based application. A requestor sends a request for quote. A liquidity provider can respond with a desired price or decline. If the liquidity provider responds, the requestor is given time to accept or decline the trade. The liquidity provider can change the negotiation price while the negotiation is live. If the liquidity provider's price change favors the requestor at the same time the requestor is agreeing to the prevailing negotiation price, the trade will be executed at new price. If the price change has moved the price to a level beyond which the requestor has signaled at the same time the requestor is agreeing to the price, the transaction will not occur. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
