How are the 24h volumes calculated?

Well, I'm mostly interest in Freicoin.
Which of these markets are used?

https://vircurex.com/welcome/index?alt=frc&base=btc&locale=en
http://bter.com/trade/frc_cny
https://www.cryptsy.com/markets/view/39
http://bter.com/trade/frc_btc

Most of the volume seems to be in the first two.


For Freicoin it's Vircurex.

Ok, I thought they could be added or something.

I'm working on providing more accurate/transparent volume counts, and will add some new coins by Monday (i'm out of town right now).  If you requested a coin please provide a method to get the total supply.

Thank you, but no, I'm not proposing a new coin, CNY is Chinese Yuan, Fiat.
My proposal is to also count XXX/Fiat for total volume.

Some days the volume in all 3 FRC/BTC exchanges combined is less than 10k FRC, while at the same time bter's FRC/CNY moves 400 k FRC or more.
For having a weighted price (averaged by volume) using FRC/CNY is more difficult, since you're using the BTC price as reference for all the coins. For that I would probably use only FRC/BTC markets for simplicity.

In the other hand, for volumes you can just add them all in FRC and then multiply by the usd price.

Here I detailed my proposal a little bit:

Ok I'm assuming only BTC/XXX markets are used for volumes as well.
I know it's more work, but they could use other markets (for example FRC/CNY) to calculate volumes even if they aren't taken into account for prices.
They just have to add all volumes in FRC (or whatever currency you're calculating) and then multiply for their usual price in usd to obtain a more accurate total volume in usd.

Anyway, the volume column is a nice addition.
