please help. Where to get reliable backtest data for m1?

 

I finally get a EA, it perform brilliantly but I found the history data for m1 is very limited (begin at April,2009) and very poor (quality:25%).

I tried to download history data from TOOLS->HISTORY CENTER. then I tested form JAN,2007 -JUN.2009,the result is terrible. but I found a strange situation.while is in prossess of testing, in the history center,the data for M1 can start from jan.1999 even not for every minutes,however, when testing is done, check it again, the data for m1 is still from April 2009.

what is the happening? where and how can I get a reliable history data to do testing?

thanks a lot in advance.
