Sister FX pairs

Hi,

I was reading a book on Jesse Livermore, who lived in the first part of the last century. He made (and lost!) millions, and described his techniques in a book in 1940.

For buying stocks he recommends checking a sister stock in the same industry group - to ensure it is moving the same way.

Does anyone do this with FX pairs?, eg: trend for GBPUSD is down, so is the sister FX pair trending the same?

Is there a list of linked FX pairs?

Thanks.

A while ago I read an article talking about correlations between the different currency pairs and it stated also the % of the time they were moving in sync. If I happen to remember correctly, EURUSD and USDCHF were like 90 to 95% in sync, EURUSD and GBPUSD around 80%, etc.

If you dig "currency pairs correlation" in Google you will probably find it. It was an interesting read.
