Title: How do i get the exchange rate between BTC and *$ without needing an intermediary step?
Post by: TiagoTiago on April 26, 2011, 02:44:20 AM
To get the exchange rate between BTC and BRL for example, currently i first get the rate between BRL and USD (or EUR) and the rate between USD (or EUR) and BTC, and then combine the two rates; how can i get the the exchange rate directly without needing to use an intermediary currency?

If you are asking how to do it programmatically,

  mtgoxusd  bid and ask amounts:
   To convert between BTC and USD use the "bid" and "ask" values for MtgoxUSD from:
  - http://bitcoincharts.com/t/markets.json

  To then convert the other currencies:

   - http://www.google.com/ig/calculator?hl=en&q=1BRL=?USD


If you instead want a human readable tool, such as a web widget:

I'm asking how to do it directly, without needing to use the USD/BTC exchange rate; i wanna know how to do it myself, without even a third party program doing the intermediary step; or is that not possible?

AFAIK there is no exchange selling BRL, so you can't do it directly. There is one order on the -otc order book as of April 26th. http://bitcoin-otc.com/vieworderbook.php?sortby=buysell&eitherthing=BRL

Select Brazilian Real instead of US dollars in pull down menu by clicking the arrow next to the word "US Dollar", you will see many other currencies. Select yours & it changes the price of BTC auto.
