Hi,
in my case, I have connected to my account fxcm and traded this script
Code:
function main()
{
  NumYears = 6;     // download up to 6 years data 
assetHistory("NZD/USD",1);
assetHistory("AUD/USD",1);
assetHistory("GBP/USD",1);
assetHistory("XAG/USD",1);
assetHistory("XAU/USD",1);
assetHistory("USD/CAD",1);  
assetHistory("USD/CHF",1);
assetHistory("USD/JPY",1);
assetHistory("EUR/CHF",1);
assetHistory("EUR/JPY",1);
assetHistory("GER30",1);
assetHistory("NAS100",1);
assetHistory("SPX500",1);
assetHistory("UK100",1);
assetHistory("US30",1);
}

and i get the 6 years history for all the assets listed.
good luck
