How long does a backtest take with 7 years of 1 min data?

[Forex Trader]

Hi,

I have imported all timeframes (1m,5m,15m,30m,60,240m and daily) into MT4. My intra-day data goes back to 1999 (7 years worth of data). My expert is about 1000 lines long. I am running the backtest now (and i know that it is calculating as my CPU is running at 50% capacity). However, I can't see the green progress bar moving, why cant i see the green progress bar moving when doing a backtest? Also, how long is a backtest of this type supposed to take, 15 minutes, or more like a couple of hours?

Thanks in advance.

Regards
