Frequently Asked Questions

What is the purpose of ccowl.com?

How are you different from other similar websites? Most websites just pull price data from CoinMarketCap. We get data directly from exchanges and show it to you without any delays.
Similarly, we scan news websites and show you the latest news as soon as they are posted.

Where does the price and volume data come from? Price data comes directly from crypto coin exchanges (Poloniex, Bittrex, Bitfinex, Kraken, Binance, HitBTC).

How do you calculate the latest price of a coin? We constantly monitor all exchanges and pick a primary exchange for every coin based on volume. Then we calculate the latest price by taking an average of highest bid and lowest ask prices.

How do you calculate volatility of a coin? We use coefficient of variation. We find standard deviation of recent prices and then normalize it by dividing result by the average price.

How do calculate coin's market cap? We use CoinMarketCap API to get the information on total supply of all coins, and then multiply it by the latest rate from the exchanges

How often do you sync with the exchanges? Every second or two for most exchanges. Kraken is the only one that limits to sync every 7 seconds.

What about news? How quickly do they show up after they are published? Most news show up in under 5 seconds.

What is OWL50? It is a market index like DOW or Nasdaq, but for cryptocurrency. It's value reflects the combined market cap of the top 50 cryptocurrencies excluding Bitcoin. We find it useful to compare growth rate of OWL50 to Bitcoin.

Will you add more coins? We only show top 100 coins. Most coins below have a tiny volume, huge unpredictable fluctuiations, and are not reliable for trading. As soon as a coin breaks the top 100, it will be automatically shown on our website (as long as its tracked by one of the exchanges we support).

Will you add more news sources? We're actively adding news sources, but if you have a specific one in mind you can request it in the form below.

What tools is this website built with? It's built from scratch using a customized Bootstrap Paper theme with several Javascript libraries.

Are you owned by a big corporation? Nope. We are an independant website.
