That wouldn't really be a bad thing. The entire point of this is to display in a simple manner the changes in price of an item -- that's one of the cases in which the graphs would have been helpful. You could have, very easily, seen the lowest price of crimson relaxes rising and thought "well, if I buy a bunch now I can sell them when the price maxes out and get a load of TC. :O!" and proceeded to do that.

How it gets the information is irrelevant! (But really it logs in to the forums and then downloads a bunch of pages from the market from which it extracts price data.)
And thanks! :3
