recently i have downloaded tick history for EURUSD since Jan 1, 2004 till now, but the problem when i back test any EA on any time frame using every tick mode, the back test stops at July 2 , 2008, so what is the possible problem that cause this.

Notes :

- when i use candle open mode during back test, it complete the test normally , but as you  know this mode has very low accuracy compared to every tick mode

- i checked the data folder and made sure that .fxt and .hst files exists for all time frames


Best Regards

It will most likely be caused by the file size exceeding 4GB... an inherent limitation of MT4. There isn't much you can do about it other than split your backtest into 2 halves.
