Everyone has different ideas about what should be filtered. Best to leave that function to the endpoint.

I'd looked at transactions data of past weeks and sometimes prices seems to jump or dive fast during a day because of really small transaction (less than 5 BTC normally) out of market prices (I'd seen transactions at 10$ when the market is at 4/5$ or on the other side transactions at 2 when the market is at 6/7$).
Why we don't ask to exchange to put a filter in their APIs so that all the transaction prices which total of money moved is belove, let's say, 2% of total moved 'till that point are not considered for min/max/averages?
I know that this kind of transaction couldn't move the total value on daily basis but removing them can smoothen the values, and avoid "fake" prices that make difficult calculate a conversion value for trade.
In this moment bitmarket.eu (to make an example from an exchange I use), has a last trade price of 4.8€/BTC (but only 10BTC sold), never in all the last 24hr there was another price like that but all the other transactions werw closed in the 3.7-4.1€ price range.
