Thank you, Stephen for your interest.

You are absolutely right, having only OpenID is not enough. We wanted to get the service up and running as soon as the main framework is ready and stable enough. Thus we limited social login options to OpenID providers.

We are already working on adding non-OpenID social login providers Facebook, Twitter, Vkontakte and others.

We chose not to implement the usual password based login in addition to social login because it takes too much work to make password-based logins secure. OpenID is by design not vulnerable to user database theft, and allows users to use very secure authentication schemes if they wish - certificates, two-factor auth etc.

We are sorry for this inconvinience with your OpenID login attempt. We'll try and do our best to fix this embarassing problem asap Smiley
Hope this will not make bad impression on you Smiley

As for the subscription price, it is 0.5 BTC per month and includes both arbitrage table and full set of charts. We'll make subscription fee more prominent. Thank you again for your feedback.

Bitcoin Analytics now has "Arbitrage" tab.

Very, very nice!


Why only OpenID?

When I try to use my preferred OpenID login:

 http://openid.anonymity.com/YesIPreferToStayAnonymous

I get:

 Error: Cannot retain discovered information; the provider does not contain the required attributes

All I was trying to do was to see how much do I would need to pay to get this arbitrage in real-time?

Bitcoin Analytics now has "Arbitrage" tab.

The table displays arbitrage opportunities for lots of 10, 100, 1k, 10k and 100k BTC between different USD markets.

The table looks similar to http://nyse-group.de/bitcoin-arbitrage and other existing tables, but it has something different under the hood:

1. It doesn't display an opportunity if there's too little volume offered at a pair of exchanges.

You can see our arbitrage table shrinking as you increase the volume. For example, only 3 exchanges have 10k BTC in their order books: btceUSD, cryptoxUSD and mtgoxUSD.  

2. It displays market order execution prices for corresponding volume instead of best prices.

In most cases, very little volume is offered at the best price - so if MtGox ticker says 5.3, it doesn't mean that you can buy or sell 1000 coins at that price. Our arbitrage
calculator accounts for that by going deeper in the orderbook than best price and displaying you the real volume weighted average price between several orderbook entries.

So you can see prices for arbitrage between mtgoxUSD and btceUSD (for example) varying with volume.

3. We extended the usual color coding from 2 to 4 colors:

- orange means there is positive price difference - you can buy low at one exchange and sell high at another one (but beware transaction fees and other commissions!)
- yellow means there is no arbitrage and negative bid-ask price difference is less than 10% - that is, market is efficient.
- white means there is no arbitrage but price difference is more than 10% - it means there is a market making opportunity, you can try to make money by putting limit orders at these two exchanges
- black means there's not enough volume on one of the exchanges

The 10% threshold is based on our subjective feeling of illiquidity and is more or less arbitrary.

4. At the top of the table you see best available execution price for the lot. You can use the percentage as a measure of bitcoin markets efficiency. The square is usually orange - so best bid usually is higher than best ask because of inefficiencies! But it's rather hard to capitalize on this difference as it requires a complicated execution strategy and will probably be eaten by different fees.  

The free version of arbitrage table is delayed by 6 hours - it shows quotes 6 hours from now. The paid version (available after you subscribe with a modest fee of 0.5 BTC a month) shows realtime quotes (fetched from exchanges using their orderbook API every 15 seconds and updated using web sockets just like the charts).

Also note, that these days arbitrage opportunities only happen during price swipes, so keep watching Smiley

Good luck in your profit seeking!

Hi Nimul,
 You've built a great looking site. Kudos on implementing data from a large number of exchanges.  This'll be a big help for the sharks.

http://bitcoin-analytics.com offers realtime charts for both order books and actual trades.

The system consolidates data to get the big picture:

1) It consolidates small trades in time, so you can see the how a particular trade moves the resulting "real" execution price.  

2) It consolidates small orders in orderbooks - so you can see the resulting "real" offer

3) It visualizes time between trades - so you can estimate how long will it take for a small exchange to execute your trade

4) Trade prices, order books and time between trades are consolidated between exchanges, so you can see, for example, the best execution price for a block trade of 10000 BTC across all USD exchanges.

All data are separated into "bid" and "ask" sides to provide more details.

Charts are adjusted for desired trade volume when it makes sense. Let you, for example,  want to trade 1000 BTC. Then price impact of one order of 20 BTC is small. However, the price impact of 100 orders 20 BTC each is large. If you want to trade a smaller amount, say 5 BTC, then small orders have a bigger impact.

The system takes this effect into account - so 3 of the 5 charts for each exchange can be adjusted for trades of 10, 100, 1000, 10000 or 100000 BTC. We figured out that this granularity is enough. Finer adjustments don't provide with better insights as charts weighted for 10 and 15 BTC are similar. However, 10 and 1000 differ a lot.

You can read more about how our charts are calculated and how they can help taking trade decisions on 'Why' tab and its sub-tabs.

Consolidated view adjusted for volume of 1000 BTC is free. Full access requires a subscription for 0.3 BTC a month or 0.5 BTC for two months. You can enable subscription for just 24h for 0.05 BTC.

My co-founder and I believe that micro-payments are the only fair business model. We wanted  0.1 BTC or less initially, but taking in account small potential user base, that won't be enough to buy us a pizza and coke off the earnings.

Bitcoin enforces financial freedom, and we think that affordable micro-payments without government interference are the key to large scale Bitcoin success. Asking for donations is a manifestation of weakness - it would mean we don't believe that our own product is useful for other people and that most of our clients will reward us voluntarily. Advertisements would mean that our visitors pay indirectly, by being conditioned into buying other goods and services and by disclosing their private habits to advertisement agencies. Conditioning and violation of privacy are against freedom so they are against Bitcoin so they are bad.

Seemingly free services always have hidden cost. For example, welfare and pensions mean that you rob your own children, as they will have to pay for them in the future. We want our visitors to pay directly and voluntarily, without hidden costs of any kind. If you only use a free part of our service - you don't pay.

You can still help us by spreading the word - use 'Social' tab to like, tweet, reddit, digg us. We are proud to be a part of Bitcoin economy - so help it grow. We plan to add more gadgets to the tab over time.  

But if you find our work worthwhile - think of your subscription fee as buying us a slice of pizza and a coke every month to encourage us, so we can innovate freely and don't have to work for corporations or be tiny parts in state bureaucracy machines. There are not many Bitcoin users yet, we won't buy ourselves yachts and mansions - we only want feel the support and excitement of doing something that brings mankind closer to the free Bitcoin-based society.

Here is what you get with subscription:

Charts for today for btc-e and 100 BTC. You can also see all volume and exchange selectors enabled:

A pattern in orderboooks on cryptox, probably caused by trading bots constantly changing their order price:

Sparse activity on btcex. It took 16 hours to sell 100 BTC there, but buying activity of liquidity demanders is stronger:
