Firstly, great site. It's my preferred site for looking a Bitcoin market data
Secondly, where do you source your fiat to USD rates from? Specifically, the rusd rates in the ticker API http://coinorama.net/api/markets
The CNYUSD rates from the ticker are different to the ones I source from my FX broker. There can be number of reasons for this like time delays and differences between CNY and CNH. Knowing the source of the rates would help with understanding the USD quoted rates for non USD crypto pairs
