# Realtime Exchange Rate Data API

There are various sources for real-time exchange rate data, e.g. Ariva EUR/USD.

Is there also an API or other source which enables to automatically retrieve real-time exchange rates as a data stream e.g. for a trading tool (e.g. in Excel/C#)?

One of the spread betting firms in the UK (IG Index) has an API freely available (at https://labs.ig.com/) that provides streaming FX rates.

You need an account to access the API, but you can sign-up for free and start using the API. They have a C# SDK available so you should be able to get up and running quite quickly.

Hope this helps.

Bloomberg's programmable plugin will do this. So will Reuters or Activ Tick or any other number of manage data brokers.

All it involves is signing a contract and paying.

I think you'll need to flesh out your question a bit more to get a more detailed answer.

Interactive brokers does offer a fair bit of data in "real time", assume its a few seconds delayed due to receiving it over the internet. I'm guessing they probably throttle their feeds to around a max of 2 quote changes per second per symbol.

Is there also an API or other source which enables to automatically retrieve real-time exchange rates as a data stream e.g. for a trading tool (e.g. in Excel/C#)?

This might just be a terminology issue but you probably want your real time data to stream to you not be retrieved as that implies polling.

• Yes I think your answer is close, can you also find a free real-time exchange rate data source? – emcor Aug 24 '15 at 18:15
• I don't know of any. Interactive brokers is pretty good about giving out data as long as you trade with them. Does that count as free? – chollida Aug 24 '15 at 18:19
• @emcor Each exchange usually makes a few days of sample data available, Exchange data usually sells for anywhere from $3000-$10,000 per year so you won't get it for free. See here for NYSE sample data and formats nyxdata.com/Data-Products/Daily-TAQ – chollida Aug 25 '15 at 12:49

Your options for real-time tick data are limited, but there are some:

Interactivebrokers is also an excellent platform thats been around for ages, and has api interfacing
