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.

Great work Alex.
Unfortunately the job is not complete until mtgox is removed too.
When/if they get fiat transfers back to < 1 week only then can they be considered a valid price source.
We do not consider MtGox as "valid price source", as for me - none of the individual exchanges are. But as long as they are not faking their ticker figures and someone is still willing to trade there even considering fiat withdrawal problems - we should count it in as one of the market players.
Since MtGox volume is not decisive anymore even for USD market (not to mention global averages) - we don't see the need to exclude it. It exists and works, it is a part of the global landscape, whether we like it or not, and we have to include it.
