Context: https://wiki.secondlife.com/wiki/Linden_Lab_Official:Live_Data_Feeds The wiki page could use a better description of the data they provide, however the page is protected so it cannot be edited by regular wiki contributors. Particularly, the LindeX datafeeds always return 0 for limit_buy_to_limit_sell periods of 1_hour and today . This seems to have been the case since at least 2010 when sample data was added to the wiki. Pointing this out explicitly would be nice, a reason would be a bonus. (Fixing the API to provide these values again would be ideal.) The update rates for the various data should also be explained, even if only a rough outline can be given. The LindeX datafeed also includes two different timestamps now (new one is tied to average exchange rate), they're usually identical, but not always. The information from the 2006 announcement should be added to the wiki as well, notably how to calculate fill-rates.
