Question regarding closing price

Hi all,
I got another question that I hope that you might be able to help me understand as I am a bit confused about this one as well.

I bought AUD/CAD as I was expecting ( hoping ;o) that the trend would follow the trend line that I had found. But it turned on me and I decided to sell to limit the loss. Suddenly the platform closed on me and I had to open it up again. When I opend it again and went back to the AUD/CAD, I seemed to not be able to see the price movement that had turned on me.

When I took a closer look at the activity log I just could not understand what had happend. I bought at 0,88085 and 0,88030 and when the price development turned on me I sold both at 0,87920.

But when I look at the price development now after I have opend my platform again, I can not see the price development that made me decide to sell. The price when I sold at 04:51 was ( as far as I understand it from looking at the details ) was 0,87920, but at that time on the graph window the price graph was not at this level.

Perhaps I am looking at this the totally wrong way and hopefully some of you might be able to help me understand it.

Thanks,
Kalle
