We have received numerous requests to implement so called "blue dollar exchange rate" for Argentine Peso. The official exchange rate is different from the real exchange rate used in the markets.
We don't know much about the real situation in Argentina, but it was quite easy to find the unofficial "Blue dollar market rate" API for the Argintine Peso. We made a special symbol for it called "XAR", and you can use it to convert from USD values with the equation parameter USD_in_XAR, like this:
- Buy: min(mtgoxUSD_close, bitstampUSD_close)*USD_in_XAR*0.99
- Sell: max(mtgoxUSD_close, bitstampUSD_close)*USD_in_XAR*1.01
According to our data sources, official rate for Argentine Peso is 5.29 ARS/USD, while according to our other data sources the blue market rate is 8.62 ARS/USD at the time of writing this blog post. Of course Argentinese should verify the rates themselves, if the data provided by us is reliable.

We are planning to target southern America more in the future, with features and translations. Stay tuned.
