Lenovo T430 or W530 in combination with a docking station support multiple monitors. The T430 also includes Thunderbolt (even though its not in the description) which means you could use an external PCI chassis with a multiple display capable GPU.

@paps I have found the LT1421 good enough for charting. 8ms is faster than I can click an order I wouldn't watch movies on it, but the portability and low power consumption is superb. You could literally set up a workstation anywhere.

I realize this thread is fairly old, but I just came across the following a couple days ago and I just want to spread the word. I, too, have searched high and low for a solution which offered me a multi-monitor setup on my laptop:
I wanted to share this new product that's going to be launched on Kickstarter.com on Oct. 7th, 2014.
I have not seen anything like this on the market. I have a 17" laptop and felt that I still needed more portable screen real estate. A lot of traders work with desktops, so this may not be an issue for them. However, to be able to carry around these screens in your laptop bag and have a whole wrap-around portable setup is godsend!
This looks like it will work with both Windows and MAC OS, so it is cross-platform compatible. The screens are the same ones used on the iPad based on what I am reading, so the resolution is amazing.
Finally, I am not affiliated with this vendor in any way, but I want their Kickstarter to be successful because this product will actually be taken from concept to production and then we can all have one (or two). If they don't meet their goal, then this just won't happen! So, join in and buy into this Kickstarter. This is the perfect product for portable traders!
