A trading desk and a training pipeline want opposite things from a data provider, and most vendors are built for one of them. A desk wants the earliest possible notice of a single event, evaluated well enough to act on without a human reading it. A model wants enormous, consistently structured volume with a history that does not lie about what was knowable when.
Those requirements only conflict if collection and delivery are the same decision. Because our nodes evaluate and stamp each record as it moves, the live stream and the point-in-time archive are the same records viewed at different distances - so the backtest that convinced a desk to take the position is running on exactly what production will see.
That is the whole argument for buying real-time data from the network that collected it, rather than from a layer sitting on top of somebody else's: the guarantees survive the trip.
