how can I get more historical data?

In MT4 I clicked "Tools", "History Center", the currency I'm interested in, and the H4 folder ... that gave me 2618 records, which go back to May, 2008 ... is there a way to go back further ... or another source for that info, other than MT4?

I listed some free historical data sources on my Tools page.

thankx for the response, but the problem I'm having is getting H4 data ... I'd found Gain on my own, and a couple others, but all I get so far is D1 data

Dukascopy offers data down to the tick.

I had looked at the Dukascopy site before, but I guess I didn't quite understand how it worked and missed the H4 stuff ... I get it now ... thankx man ... that did it ... exactly what I need ...
