Have important update - we've made a decision on chinese exchanges suspected in faking trading volume figures.
fxbtc integration changed to calculate actual trades and now it shows a much lower and probably real volume.
okcoin does not provide trading history data, so we can't go that route. So okcoin has been removed, it's put to ignored exchanges list now.
btctrade - removed also, for same reasons.
As a result of this CNY market trading volume shrank by around ten times, and now has much lower influence on global average price.
If someone has any information relevant to the case - we're happy to listen. We will probably review this decision once this situation will remedy itself.

Why huobi isn't there?
Huobi is currently ignored due to its extremely high trading volume (which has now been confirmed as being due to their 0% trading fees)
We are seeking a solution so that we can integrate exchanges of this nature without it significantly distorting the price. If anyone has ideas on this feel free to contact us
