How is this possible?

This happened on thursday, LIC housing had made a day high of about 1074 in both BSE & NSE. However, it had already made a day high of 1046 in BSE within 5 minutes of market opening. So, I could see the day high of 1046 but I could not see the same thing in the graph. I was using tradetiger & I thought maybe theres some mistake with the software so I went to http://money.rediff.com companies & there again I saw the same thing, the same high of 1046 but I could not see the value being reached in the graph.
How can this happen?? By the way, I also took a screenshot of tradetiger if it helps.

I could not get what you want to say/ask but day high was 1083 around 3:30 PM. I can see these value in Chart on Amibroker.

Let me correct myself, day high was 1083 as you said on 15-7-10 when the market closed.
But at about 9:04 am the day high was 1046 on BSE but I could not see it in the graph. I was seeing values till about 1014 only in the graph.
Of course the day high increased later to 1083 as values crossed 1046.

These are block orders that generally happen before market open.Manipulative moves these.
