To switch between different exchanges and between predefined trading volumes two independent controls can be used to focus attention on one exchange and one trading volume scale at a time. The 'allUSD' ticker is a consolidated view of all exchanges.
The indicators are calculated for allUSD the same way, as if it was a real exchange. The order book of this composite exchange is just a standard consolidated limit order book compiled of all supported exchanges - that is, limit orders on all exchanges joined together and ordered by their respective limit price. The consolidated trade stream is just trades on all exchanges joined together and ordered by execution time stamp.
The computed charts for allUSD provide insights of what happens at Bitcoin market as a whole. For the first time it is possible to see how activity on any particular exchange differs from the market in general. Without saying that consolidated order book can show which arbitrage opportunity actually available depending on trading volume of the whole market and how it changed over time. For it almost always is, but if you want to trade less than BTC, the best available price is almost certainly a second-grade exchange having enough volume.
In most cases the benefit from selecting the right exchange and the right trade execution strategy financially outweighs our moderate subscription cost - so if you trade Bitcoins often, think of supporting us, so we can develop more visualizations and analytical tools and add more exchanges. Bitcoin markets are illiquid markets with relatively low volumes where price for market orders varies significantly depending on demanded volume.
Implying illiquidity of bitcoin markets, traditional tickers of best bid and ask prices are not relevant for practical trading. To help assessing price for the given volume of bitcoins, exchanges provide with so called Level 2 Market Data, including full anonymized order books. It is now possible to answer the question what is market price of the given order volume. Bitcoin exchanges have somewhat non-standard notion of market order. They assume that market order allows one to buy given volume of a financial instrument at its current price.
However, a widely accepted definition is that market order buys you a given volume at its best available price without respect to the price. The difference is tremendous. For example, a genuine market order for BTC on MtGox will be executed immediately and it will shift the price a lot, so the resulting average price the execution price will be much worse than the current price.
However, with current implementation of market orders when you choose to place a market order, you are suggested current price, which is not what you will actually get. We checked all of the 12 which declare an MKT capability. The current implementations assume infinite liquidity which is the case neither at MtGox talk less of smaller exchanges not on really big exchanges such as NYSE.
To calculate the price, we go deeper and deeper in order book until we fetch the declared volume e. Then we divide total BTC by total USD, get the actual market price for a given volume and display how it varies with time.
Note that the system also accounts for limited volume of order books. Sometimes you cannot trade BTC at all because there are not enough offers from liquidity suppliers. Sometimes you can, but most of this will be spam orders at very unattractive prices. Our chart reflects these phenomena. Our idea is to calculate such market price for pretty arbitrary a set of volumes: 10, , , btc. We assume that although for practical trading prices for different volumes have to be calculated, these selected volumes allow quick analyzes of the prices distribution and volume capacity on the given market.
Additional step toward Level 2 Market Data implies a possibility to analyze market activity separately for buyers and sellers. Thus separating dynamics of bid and ask allows deeper understanding of the market. On one side, there are traders, buyers and sellers, who provide resources for exchange — liquidity providers.
And on the other side, there are traders who are willing to consume those resources provided for exchange — liquidity demanders. A market can be considered as two groups of traders standing in front of each other. Thus current order book volume can be measured by summing up all USD on the buyers side and all BTC on the sellers side.
Note that special care should be taken to separate 'real' data from 'noise' and 'spam'. What is order book volume? The order book volume is certainly not 1 million dollars - these dollars are an illusion which materializes only when the order executes.
And in this case the order will never materialize because of such a grandiose price. In fact, order books provide no information to perform such conversion. In contrast with traditional exchanges, bitcoin exchanges do not require high entry price for a trader. Such trades usually executed hundred and thousand times in 24 hours on MtGox. Such trades are executed times in 24 hours on MtGox.
Both groups will ask different questions about the price prevailing on the current market depending on preferred order amounts operated by the trader. Buyer will be interested in current market price to buy 10, , , amount of BTC depending on his strategy and financial resources at hand.
The same will be with Seller who will be interested in current market price to sell 10, , , BTC. Order books provide us enough data to calculate bid and ask prices for given BTC volumes. Gathering historical bids and asks for given BTC volumes, allows to analyze price valuations distributed in time and depending on the BTC volumes available for trading.
Thus activity of liquidity suppliers can be further illustrated. Our understanding of the market will be incomplete without knowing activity of liquidity demanders. Contrary to the activity of liquidity suppliers, which can be gathered from order books, volumes of BTC trades actually executed on the exchange represent activity of liquidity demanders.
These indicators can help us answer following set of questions. What actual trading activity pattern prevailed recently on the market? At any given moment selling activity can prevail, and at the next period of time buying activity can prevail. If we take a look on Mtgox charts we can see that it has relatively high trading activity in volumes of 10 BTC or below.
And for BTC this time in general can exceed hours in a last 24 hour period. Although, for any given period of time and market state this indicator can significantly vary, we still can make comparison between different trading activities, depending on volumes which were traded. This is an experimental indicator which we assume can show what variety of indicators in general can be provided by our service.
It is easy to imagine that if in general on the market small traders activity is prevailing over big traders activity then we can expect that relatively small volumes below 10 BTC will be traded much frequently than bigger amounts of BTC and above.

Korea Muyao Shen Jan 5, First up is Aline Henderson , who writes, "What, if anything, is the meaning of a stock's bid and ask sizes?
On the New York Stock Exchange , only the specialist has this information, which he keeps in his or her "book. The electronic communications networks used by brokerages and day trading firms offer a window into this world through the wonder of Level II order flow data, which includes the volume and prices of the mountain of bids and asks behind the quotes you pull up on Yahoo!
Message Center Memo to Calvin Lui , who wonders what it means when trading in a stock is halted or delayed because of "imbalance": On the NYSE and the American Stock Exchange , it's normally the job of the specialist to provide liquidity -- that is, to ensure that buyers and sellers can easily find someone to take the other side of their trades.
When no one's there to take that side, the specialist steps in and trades stock from his or her own inventory. But sometimes things get a little too out of hand. If there are too many buy or sell orders for an orderly market to be maintained, the exchange will declare the stock to be in "imbalance. During trading hours, trading in such a stock is suspended until liquidity returns. But ironically, the most volatile sectors -- the Internet and technology sectors -- trade on the Nasdaq, which, because of logistical difficulties associated with its competitive market maker system, has never halted or delayed trading in a stock because of imbalance.
Memo to Howard Lorch , who wonders what the deal is with double-counting on the Nasdaq: How the Nasdaq counts its trades has been something of a hot-button issue ever since it surpassed the NYSE as the busiest stock exchange. In fact, concerned with what it saw as excessive transaction fees, the Securities Exchange Commission last year pressured the National Association of Securities Dealers to approve a resolution eliminating the practice of double-counting what are known as "riskless principal" transactions, in which market makers match buy and sell orders without risking any of their own capital.
