how to load the entire history on my EA backtest

 
Hello,
I have a little problem with MT4.
When I test my EA on a 4h TF on MT4 from 01.2007 to 12.2007 the history just goes back to may2006. with the Print command I see that the Bars also just go back to May 2006.
I test offline and my offline historydatabase goes back to 2004. My EA needs this history of several years back. -the longer the better. This EA learns from the past and without past it can’t learn…
How do I tell MT4 to load the entire history bank? With Extra->option->diagram I already placed the max on chart and history to 99999999999 but this didn’t influence the EA history.

I hope someone can help me on this.
