Access control of an electronic exchange network

An exchange computer system comprising:

• at least one communication interface connecting a plurality of remote computing devices with the exchange computer system, wherein at least one of the plurality of remote computing devices is configured to exchange one or more electronic objects using the exchange computer system;
• a matching engine comprising at least one hardware processor, and at least one non-transitory computer-readable storage medium coupled to the at least one hardware processor and configured to store software instructions that, when executed by the at least one hardware processor, cause the matching engine to perform operations comprising:
• receiving, from a remote computing device with a graphical user interface (GUI), data encoding a first conditional transaction request for exchanging the one or more electronic objects, wherein the GUI is configured to capture one or more user inputs by a submitting user that determine the data encoding the first conditional transaction request;
• identifying, based on the first conditional transaction request for exchanging the one or more electronic objects, a second transaction request for exchanging the one or more electronic objects;
• determining that the second transaction request is a likely match for the first conditional transaction request when the first conditional transaction request is at least partially met by the second transaction request;
• transmitting, to the remote computing device, data encoding an invitation for the submitting user to firm up the first conditional transaction request;
• and
• responsive to receiving, from the remote computing device, a reply to the invitation indicating that the submitting user firms up the first conditional transaction request on the GUI, executing the first conditional transaction request and the second transaction request such that the exchange computer system allows the submitting user to exchange the one or more electronic objects with the algorithm-driven software agent despite varied responsiveness.
