I entered a long limit order at current price, and when it was filled, the DOM showed the position at about 15 ticks above the price I asked for! It also showed a matching loss. After I closed the position, I found that the order had executed correctly, but the DOM had displayed the wrong information. I tried several more orders, with similar results. I attach screenshots of the DOM for the last two, which were short orders. They also show the position about 15 ticks above where it should be, with a matching (bogus) profit.
I can supply the log file on request.
This behaviour shocked me.
After restarting NT, the DOM shows positions correctly again.
