Very annoying bug: NT forgets(?) cost basis

[geoninja]

This happens occasionally, a few times a month. FYI, I trade >1K ES RTs per month.
I use static superdom and also have chart trader enabled on my trading chart. Thus normally, both the superdom and the chart show my orders and cost basis.

However, sometimes the cost basis gets completely messed up. It may happen that on entering a short ES position @ 1200, both the superdom and the chart trader will show an unrealized loss of 1200 points with ES still @ 1200, i.e. NT will think I had shorted ES @ the price of Zero! WOW!! It was a real shocker the 1st time I saw it happen! Of course, it also results in the ES chart getting squeezed against the top of the chart window (on semilog chart), so I would need to switch the chart trader into Sim mode to be able to see current prices.

Most of the time I saw it happen with short trades where NT remembered an entry price of zero, and I think it happens regardless of position size.

The cure is to quit and restart NT. I have been seeing it with various versions of NT7, currently running RC1.

Two examples attached, from the log.

Brett, I forgot to add two things.

Fortunately, this bug - although really annoying - does not affect P/L calculations for the day, or in the performance report, as orders and executions are still recorded with correct prices. The correct price just gets lost on its way to the DOM and chart trader.

The other thing is that when it happens, something becomes "off" in NT, and any successive trades are bound to suffer from the same oddity. Restarting NT seems to cure the problem.

I am sending you the log and trace files shortly. Thank you for your help.
