I'm not defending their crappy simulator. I just pray that you can defeat these guys on their false fills with your side challenge. I cannot abide a web-based javascripty simulation. It simply does not equate to the real world.
I have to keep refreshing my browser window to see the real stats. (It stops displaying a live data feed after every few minutes.) But each time I do, I have to reload the chart setup I've saved...such a pain. But based on my current P/L figures, I do believe that if I had short NQZ9 where I had originally intended, I too would be showing a Total P&L of from $4,000 to $5,000. That aspect of the challenge I personally do not think is rigged.
