Abstract: A trader of a financial instrument bundle is informed of a difference between the desired price of the financial instrument bundle and a currently available price for the financial instrument bundle. The price differential, displayed on the trader's trading screen, may be in the form of a numeric value. The numeric value and/or other indicator may have a variable property (such as color or dimension) to indicate the price differential.

Abstract: A collection of one or more trade orders for a financial instrument is priced or re-priced to one side of a market center order book based on a target execution price (representing the least favorable price acceptable for all trade orders of the collection), a book depth (representing the collection's book depth), a total order quantity (representing the total quantity of financial instrument units to be traded), and a maxshow (representing the maximum quantity to be shown on the order book at each price level of the book depth). Any existing orders of the collection that are too close to the current market price or too far from the target execution price are canceled or CXR'd, starting with the closest price level to the current market price for “too close” trade orders and the farthest price level from the Target Execution Price for “too far” trade orders.

Abstract: Trading of multi-leg strategies is facilitated by a computerized system and method that enables a trader to efficiently define and trade a multi-leg instrument while minimizing leg risk. The multi-leg instrument may be defined to include one or more execution triggers, such as contingencies that delay submittal of trade orders for contingent leg instruments until the contingencies are met, and dynamic re-pricing that re-prices the leg instruments when a market update is received. The precise method of execution will vary according to how the multi-leg instrument is configured. Trade orders for contingent legs (including contingent legs configured for dynamic re-pricing) are held in abeyance until all contingencies have been met. Trade orders for non-contingent dynamically re-priced legs are submitted immediately at a leg price and leg quantity. Trade orders for non-contingent, non-dynamically re-priced legs are submitted to an exchange when the market crosses the multi-leg instrument (i.e.

Abstract: Financial instruments may be electronically traded according to any of three modes, including single instrument mode, correlated mode, and aggregated mode. One of more market depth representations showing current market price levels, Bids and Asks of the financial instrument(s) to be traded are displayed on a GUI window. The user mouses parallel to the market depth representation to a price level at which the user wishes to initiate a trade, and the moused-over price level is selected and highlighted for all correlated market depth representations displayed on the GUI. All trade order parameters are pre-constructed either prior to selecting or upon selecting of a price level. The user then clicks a mouse button or initiates some other action of a user input device to place an order.

Abstract: A unique method and apparatus for analyzing data related to a tradable financial instrument employs a finite state decision tree as a predictive model of future trade prices for the instrument. The decision tree may be multi-layered with each layer divided into nodes representing a range of numerical values. For each layer of the decision tree, a user-selected or user-defined analytic equation/algorithm processes the data into numerical analytic values that are used to populate the nodes of the decision tree. A future price offset is determined for each node. The future price offset represents a prediction for a future price change of the financial instrument and can be used as a basis for trading the instrument.

Abstract: A model of assumed price behavior of a financial instrument is used in trading the financial instrument. The model includes one or more analytic levels containing analytic values divided into nodes where each node is associated with a future price indicator (such as a price offset) of the financial instrument for a particular look ahead interval. For each analytic level of the model, a current analytic value is related to one of the nodes of that analytic level and a trade order is generated when the future price indicator associated with a node to which the current analytic value relates meets a trader's criteria for trading the instrument. Generated trade orders may rest on the book or be filled immediately. Resting orders may be re-priced as market conditions or current analytic values change. Optionally, a trader may specify an edge that triggers submittal of the trade order to an exchange when the future price indicator meets the inverse of the specified edge value.

Abstract: A method and apparatus enables quick and efficient adjustment of parameters of a strategy for making markets in a financial instrument traded on an electronic exchange. Implemented in software, the market making adjustment apparatus and method employs a user GUI (Graphical User Interface) with areas of the GUI configured for adjusting market making parameters such as Book Depth, Aggression and Bias. The user is able to map the adjustment areas of the GUI to specific levels of parameter adjustment.
