Optimazation on two computers shows different result why?

[Mathias Halen]

We used the same EA SET but the only different is that I have a DEMO account and my friend has a LIVE account.

why is it showing us different results?

demo price data will not be identical to that of live account price data. different data gives different backtest results

[zzuegg]

that can also be seen in the datafield ticks modelled: on your first test there are 3706425 and on your second 3621586

threre is a difference of 80.000+ ticks.
