One was on LTRON, which showed up in my port twice as two 50,000 share holdings (still there). The other was for 39CLU, which showed up as being purchased for double the list price, and a 1.8 million loss. I've emailed support. Hopefully they'll correct those errors promptly. If this is a recurring glitch with the new system, they should really do something about it. My double trades took place during the start of commission free time, so I assumed at first that the loss was due to other market movements, and might not have noticed at all had I not read about Catzan's similar problem. I also wonder if this glitch could end up being exploited for gain. If I had been shorting 39CLU, and the double trade went through, I presume I'd be showing 1.8 million gain. Definitely something worth fixing to maintain the integrity of the game.
