Put the trader's chart and its time compressor on a past window: the market, the window, the speed to play it at and, optionally, the moment to hold on (a trade, a sweep, a touch of a level). The studio shows a card; pressing it opens the chart there, held and ready to play, with a way back to the studio. Use it whenever you talk about what happened in a window: show it on the chart instead of only describing it. Past windows only, ten minutes to thirty days; a replay shows what printed, never a forecast.
