[Dubious]

I've just been noodling around in the demo and noticed in the Commodities Exchange that alternate lines are different colors: primarily amber and white. Initially I thought these were just to make it easier to keep the lines separated. And then sometimes a third color appears: red. So, is there a significance to the line color?

Also, sometimes when I go back to an earlier (lower numbered warp space) the "best buy/sell" information goes back to a "?". Are these reset after a specific amount of time or randomly? (Going to make trading a pain.)
