An embodiment of the present invention provides computer-implemented methods and systems for optimizing the executing an order, such as trading orders. An order may be electronically routed to an Execution Optimizer (“EO”). The EO may apply a particular profile to the order, corresponding to a particular portfolio manager. Next, the order, with the profile, may be routed, electronically, to a third party where a prediction model may be applied to the order, indicating trading parameters for the order. The order, with the trading parameters from the prediction model, may be passed back to the EO, where a rules engine may apply rules, specific to the executing financial institution, to the order. The order may then be passed to a selected broker for market trading.
