Where do I get historical data for backtesting?

[Forex Trader]

Hello,
I'm trying to backtest my expert advisor, but my data only goes back to May-29-2006. Is there a place to download older data, so I can back test for a year or more?

Thanks,
Spencer

I tried these, but they only have 1 minute data, which doesn't seem to work for my 1hour backtesting. Am I missing something here?
