have not seen the video but....I guess you are referring to Infinity platform. If you closed your orders then one of the 'closed' P/L box at the bottom will not move but the other column next it will be moving as prices jump around. I would think Carter is smarther than that...again have not seen the video you are talking about...in general he is very well versed.
Just enormous losses virtually every day. As for the endorsements John Hill is a publisher not a trader, Price Headley is not a profitable trader I have heard, Mark Douglas is either modestly profitable or unprofitable from what I have heard, and Carolyn Boroden is a technical analyst not a trader. 90% or more of people that sell trading education products are either not traders at all or unsuccessful traders. If someone has something that works they are not going to sell it to you for 29.95.
Here, compare these two videos: http://www.youtube.com/watch?v=BK9JwGf40NU The P&L boxes at the bottom right of the trading ladder don't change as each target is hit in this video; they only do that on the demo version of InfinityAT. In this video it changes as each target is hit, as it should with the cash version. http://www.tradethemarkets.com/public/1846.cfm
Interesting observation, it could due to that in the Youtube video the top of the platform is not shown where it says SIM.
Yeah, interesting huh? There's a lot of videos on YouTube of supposed live trades where the top of the trading ladder is conveniently covered by an arrow, or some text, or it's off the screen, or whatever.
The AT platform allows you to select "Display Realized PNL" and "Full Fill P&L Calc". The supposed discrepancy you note could be attributable to this.
