So for HDT it should get 210 datapoints correct ? Is this a bug ? Thank you Tony

That request should be returning 210 datapoints prior to and including 20120711. We will get this fixed but I don't have an ETA currently so I would certainly recommend using a workaround on your end. There are 2 workarounds I can think of currently. The first would be for you to use the HDX command and filter the results by date range on your end. The second would be for you to calculate the number of days between the current date and your request time and add that number of days to your max datapoints request parameter.
