Prices are rescaled and dates hidden so you can't recognise the chart by its level. Normalized mode shows every chart as % change since its first visible day and you trade dollar amounts, so no share price is ever shown. One game year = 252 trading days. Keys: Space pause, → step one day, +/− speed.
