Six rounds. Six eras of market-information speed, from the 1857 transatlantic wire to a 2025 AI signal that prints faster than a human blink. You get the era's real reaction window. Most readers time out from the Bloomberg era forward.
Each round drops you into a real wire dispatch from a different era of market-information speed. You read it, you watch the timer drain, and you pick BUY, SELL, or HOLD before the window closes. The early eras give you time to think. The late ones do not.
