Abstract: A system and method for conducting security transactions provides a system with a client device with a client interface, an inventory account and a trading engine. The trading engine processes a client buy, sell, sell short or buy to cover order. The trading engine enables a trading of fraction shares in real time as well as reduces a frequency of orders sent to market by executing principal trades against the inventory account.

Abstract: A system and associated method allows a client to balance the client's security portfolio that includes constituent securities. A client device is provided with a client interface. A host server is coupled to the client device and executes logic resources for balancing the portfolio. A balancing engine allows a client to manipulate the client's security portfolio and keep it in balance at all times. The balancing engine provides that any constituent moved by a client remains at a declared level and remaining constituents are proportionally balanced so that the sum of the weights adds to 100%.

Abstract: A system and associated method for conducting index or theme based basket security transactions includes a client device with a client interface, and is configured to receive an index or theme based basket client order. A host server is coupled to the client device and executes logic resources for carrying out transactions for a client. A pricing engine, an inventory account and a targets engine are included. The trading engine is configured to process the client index or theme based basket order as a single order. The trading engine enables the trading of fraction shares in real time as well as reduces a frequency of orders sent to market by executing principal trades against the inventory account.

Abstract: A system and associated method with a target number of shares for conducting security transactions includes a client device with a client interface configured to receive a client buy, sell, sell short, or buy to cover order. A host server is coupled to the client device and executes logic resources for carrying out transactions for a client. A pricing engine and inventory account are included. A targets engine determines the target number of long and shorted shares of a security to be held by the inventory account.

Abstract: A system and associated method for conducting security transactions is provided for hedging of market exposure or harvesting of tax losses. A client device with a client interface is configured to receive a client order for hedging of market exposure or harvesting of tax losses. A host server is coupled to the client device which executes logic resources for carrying out transactions for a client. A pricing engine and an inventory account are provided. A trading engine processes the client order of hedging of market exposure or harvesting of tax losses. The trading engine enables the trading of fraction shares and reduces a frequency of orders sent to market by executing principal trades against the inventory account.

Abstract: A system and method for conducting security transactions includes a client device with a client interface. A host server is coupled to the client device and executes logic resources for carrying out portfolio transactions for a client. An inventory account and a pricing engine are provided. A targets engine calculates a target number of long and short shares of a stock to be included in the inventory account to meet present and future buy, sell, sell short, and buy to cover client orders.

Abstract: A system and associated method for conducting security transactions includes a client device with a client interface configured to receive a client buy, sell, sell short, or buy to cover order from a client. The client is associated with a social media network and has at least one social network friend. A host server is coupled to the client device and executes logic resources for carrying out transactions for the client. A pricing engine and an inventory account are included. A targets engine determines a target number of long and shorted shares of a security to be held by the inventory account. A social networking engine allows clients to share information for at least one of, portfolios, orders and investment ideas. The social networking engine allows users to execute securities transactions based on the shared information.

Abstract: A system and associated method if provided for rebalancing a client's portfolio of securities. A client device is provided with a client interface that is configured to receive a client's rebalance order which includes fraction shares. A host server is coupled to the client device and executes logic resources for carrying out transactions for a client. A pricing engine and an inventory account are included. A targets engine determines a target number of long and shorted shares of a security to be held by the inventory account. A trading engine that is configured to process a client's rebalance order of a client's portfolio. The client receives a list of current positions, selects a share-weighted portfolio, chooses an alternate weighting, and decides to: (i) add funds, (ii) remove funds or (iii) rebalance the share-weighted portfolio.
