4hr data

I am looking for historical 4 hr forex data to test a system. There are some free charting softwares on web like the one on FXCM site, but it goes back only 1000 periods which is January 2005 and this is not sufficient to test a system.

Can you please recommend me some free charting software including 4 hr data and some basic indicators available and it goes back 3-5 years. I can also use raw data that can be converted to Metastock data so that I can use Metastock indicators.

Thanks

I'm using metatrader 4. I've just checked to see how far back it goes, and it went back to 2001 before I stopped it. Heres the link.

MetaTrader charts back to 1978.
