Headlines generated by the simulation: earnings surprises, economic releases, company events, political developments and running storylines. They are ranked by the size of the price move they caused in something you hold rather than by how recently they arrived. A reverse-chronological feed buries the one story that cost you money under nine that did not.

News is not decoration here: an event applies a shock to the affected company or sector, which reaches the price through the mispricing process, which is why the ordering rule is possible at all.
