Arbitrage charts anybody?

[giszmo]

Just read about a new exchange in Colombia where the BTC was last traded for 9471COP which seams to be 5.21USD. At https://btcchina.com/ the BTC recently peaked at 5.67USD.
Does anybody have a chart of exchange rates in USD for non-USD-exchanges?

Probably a good time to buy on Gox, then.

Euros are on their way. How long may it take? It's 4 days already. The last 2 times I had to message the support to get it charged but I can't believe this is standard.

for customers in the US, there is strong supply depth at CampBX and BitFloor in the 5.10-5.11 range, about 1% below Gox price.

Not all markets are considered but there is this arb opportunities list:

And if you know about where the currencies cross, you might be able to eyeball opportunities from here:

Yes, the first one is an interesting link to bookmark. Thanx for that.
Great would be of course a top arb list of all exchanges with a filter "last trade younger than x days".

See https://bitcointalk.org/index.php?topic=82768.0 for more info.

If you have questions or ideas how charts or arbitrage tables can be improved to fit your needs - let me know.

Definitely more interesting than the other link but I miss non-USD exchanges.

I am only curious and will not do arbitrage so don't bother if I'm the only one asking

[genuise]

If we consider arbitrage opportunities even between exchanges of one currency, for example if we take USD exchanges
it is very important to understand that to realize it we need to be able to execute two transactions at the same time.

One transation to sell some amount of BTC on one exchange and second transaction to buy the same amount of BTC on different exchange.
As we can see we need to pay attention not only to the bid and ask prices on corresponding exchanges but also to BTC/USD volume actually available on the corresponding exchanges.

Here is screenshot from bitcoin-analytics.com which demonstrates that at the moment there is an arbitrage opportunity between mtgoxUSD and btceUSD for the volume of 1000 BTC, and also between mtgoxUSD and cbxUSD.
For the mtgoxUSD/btceUSD difference is 101 USD if you execute such transaction
and 110 USD difference will be for mtgoxUSD/cbxUSD pair.

Also notice that composite arbitrage opportunity for both variants together allUSD will be 121 USD (if you split 1000 BTC and make two transactions together: one part with mtgoxUSD/btceUSD and also second part with mtgoxUSD/cbxUSD)


It is easy to imagine how this can be extended for multi currency arbitrage case.

I'm interested in arbitrage because I can imagine, people in one country will not be eager to buy bitcoin when they see it is much cheaper in another country not because I have the means to do arbitrage myself. To my understanding, arbitrage provides liquidity to smaller exchanges and of course the more complicated it is to transfer money to or from that exchange, the higher are the opportunities for those doing it well.
The post above mentiones something about instantly buying and selling at 2 exchanges which is only a necessity for if you don't compensate these structural weaknesses of some exchanges but try to profit on sudden movements. The former I'm sure exist more between different currencies. Bitcoins are simply not mined big style in the area of certain currencies.

Slightly off-topic: for those into arbitrage, betsofbitco.in migh also offer an opportunity to do some arbitrage

[genuise]

Yes and No.

Yes when you think about providing liquidity between different exchanges and between different currencies so as such in general in the whole bitcoin currency exchanges market.

But this task of providing liquidity cannot be solved without strong incentive from liquidity providers to profit from those currently opened arbitrage opportunities. And they also are interested not only in nominal currency exchange rates but in their quality. What can be a quality of such arbitrage opportunity? I think the quality is the actuall volume of the transaction (it is obvious that there can be a significant difference whether you operate with 10 BTC or 1000 BTC, the profit will be siginificantly different). So the task of discoverying arbitrage opportuinity consist not only in finding the best prices but also in finding the best prices for a given transaction volume.

So back to your suggestion, Yes arbitrage in general view is about providing liquidity for the whole bitcoin market, but the mechanism of price and quality of arbitrage opportunity depends on discovering the price for a given transaction volume. This quality adds real effectiveness and thus improves the speed of decision making and speed of compensating market inefficiencies and thus lessening friction and improving the whole bitcoin market which is one of the main advantages of the bitcoin, is't it?

Here is a screenhot to further illustrate my point from previous post.

Here is combined  allUSD price chart for 1000 BTC volume which shows how price was changed in a period of less than one hour (there was 10000 BTC bought in this period) And in the table there is current state of resulting arbitrage opportunity which increased from 100 USD to approx 300 USD for 1000 BTC volume

[giszmo]

Arbitrage generates higher %% opportunities for lower volume. If you want to move millions, BTC arbitrage is nothing for you.
If all arbitrage opportunities are taken, smaller exchanges get the liquidity they need to take off and people in more exotic countries will get their hands on bitcoin more easily. Only for that last point I am interested in non-USD arb opportunities.
