The first half of the trade also will get recalculated after 3 days taking to account the median price, not the minimum price.
So, if the price of HIVE stays stable for the next 3 days starting from now, you get the HBD exactly at the rate of $1.05.
Oh wow, that's actually a great feature. Thanks for the info, this should be explained in the peakd faq in the convert window.
