That animation is very interesting. My impression after watching for a while is that while the price increases are fairly gradual, the decreases are quite rapid. Especially the drops from the high prices seem quite dramatic in both scale and speed. How rapidly they occur may be exaggerated by the time scale of the animation, but it still seems much faster than the growth rates. Which gets into questions of how quickly communications between sectors theoretically occur, and the amount of abstracted "non-player" merchant activity that occurs to cover the market. But the real "meat" of the problem in gameplay terms is how well a given cargo size ship can juggle profitability versus operating costs.

Despite my current comments on the subject, I would say a separate "trading" topic should wait until the release of the game, when people have a chance to see what the manual reveals about it, and how the new model works out in action.

Any plans to "beta test" it in a new demo?
