Maybe we need add a parameter to balance the exchange of feed price, the wittness exchange of the BTC, USDT, USD, BTS, DOLLOR, CNY were so different.

First: Remove the maximum and minimum effective feed price;

Second: the parameter Z=(The sum of the top five maxima effective feed price - The sum of the last five minima effective feed price)/(The sum of the top five maxima effective feed price + The sum of the last five minima effective feed price);

Third: the Final feed price=median of witness feeds*(1+the parameter Z)

how about?
