Methods and apparatus provide for calculating expected present values and conditional probabilities of future payments of path-dependent rules-based securities or derivative contracts using iterative conditional probability calculation methods, including: (a) breaking a payment horizon of the securities or derivative contracts into N time increments over time t=0 to t=N; (b) initializing an array of state variables to assumed values at t=0; (c) applying transition probability models to the assumed values of the state variables at time t=0 and calculating a joint probability distribution for the state variables at time t=1; (d) applying payment calculation models to both the t=0 and t=1 values of the state variables and calculating probabilities and expected present values for the securities or derivative contracts payments occurring between t=0 and t=1 based on values of the state variables at times t=0 and t=1; (e) repeating steps (c)-(d) iteratively at each time t and calculating joint probability distributions for the state variables, probabilities, and expected present values of the the securities or derivative contracts payments occurring between times t and t+1 based on values of the state variables at times t and t+1; and (f) summing the probabilities and the expected present value calculations across time and values of the state variables to obtain the expected present values and conditional probabilities of the future payments of the path-dependent rules-based securities or derivative contracts.

Systems and methods are described herein for supporting the trading of bonds in a computerized system using broker dealers as intermediaries. Broker dealers receive orders relating to particular transactions and have the option to accept the order by submitting a matching counter order, or to rebroker the order with the same or modified terms to a number of other investors or additional broker dealers. The additional broker dealers have similar options, thus providing a system wherein orders can be quickly proliferated to a large number of parties. This order proliferation can be fully or partially automated through the use of predefined rules stored in a database which dictate for each broker dealer whether, to whom and under what terms to rebroker orders. When an order is received, the system processes all such rules to output a set of orders which are then communicated to the corresponding parties.

By using the foregoing iterative conditional probability calculation methods it is possible to evolve a composite state variable CSV in a path-independent manner and use CSV to calculate present value cash-flow of a path-dependent rules-based security.

Methods and systems are described herein for facilitating rules-based communications between two external sources. The system comprises a non-transitory storage device that has embodied therein one or more routines operable to deliver initial communications and responses thereto between a first user and a second user. One or more processors are coupled to the non-transitory storage device and operable to execute one or more routines. The one or more routines include the first user's authentication routine, a rules processing routine, a communication processing routine and a communication matching routine. The method allows for communication between anonymous external sources through a set of software commands configured to improve the functioning of a system of programmed computers and one or more servers, said system tasked with facilitating, through intermediaries, communications between two or more users, including a first user and second user.
