Gui_DownloadPrices
Posted: 03 Jul 2010, 00:23I just committed a new GUI screen for downloading up-to-date pricing from magictraders.com.
I spent a fair amount of time figuring out how to deal with extreme price differences on some cards. My solution was if a price is more than 50% different than the price already read into the HashMap, then the higher value is divided by 2 before being averaged.
Nonetheless, expect card values to increase on average. The first time I opened the card shop with the new prices, I had many more cards worth selling.
There are at least a few cards missing from the price list. magictraders.com is missing them outright. Unless someone can point me to a different price list, (text format - there are a couple other lists I've found, but they're formatted HTML tables) we'll have to live with the few omissions.
I am also planning on tweaking the ReadPriceList to randomize the prices a little bit each time. Something like 90% chance it's (+/- 10%) 10% chance it's (+/- 50%).
