Difference between backtest e real trading

 
I tested an EA and I saw that there are some errors in back test..For example, it say me that it entered Short on Eur/Usd at the price of 1,2665 at the 14:40 of 9 June 2006..I controlled that bar, but it never touched the price of 1,2665!!!! How it is possible? In that way every backtest is wrong

Try to look at that time: the difference is about 30 pips!!
 
Check "recalculate" box and try again.

As you can see, it close one lot at 15:17 of 2006.06.09 at the price of 1,2624 and, in the same minute, it opens two lots at the price of 1,2663...If you look at the chart you can see that, at the 15:17 it was very far from 1,2663..
 
Here is an other example: http://img338.imageshack.us/my.php?image=screenshot2jd3.jpg

It close 2 lots at 15:10 of 2006.06.15 at the price of 1,2638 and, in the same minute, it opens 2 lots at the price of 1,2618..And, also in this case, if you look at the chart you can see that, at that time it didn't touch that price..
