This is what is coming for the exchange. This screenshot is from me mocking up the chart layout. Those are wired up now. I cleaned it up a little and desaturated some of the colors more. For staring at the screen trading all night

I took some inspiration from bitcoinwisdom for the trading interface.

Particle of course will feature prominently on the exchange. The system architecture is really cool. The backend is a decentralized/distributed architecture running on very similar core technology as MaidSafe. This is not one of those one page PHP exchange scripts with hot wallets on the web server

This is a multi-tier message oriented architecture designed for scalability and to handle high volume. The trade engine is built on similar architecture as the LMAX principle - high performance single threaded trade processor, avoids race conditions and locking issues.
This has features that will appeal to pro traders. Stop loss Take Profit, range orders (e.g. I want to buy 1,000,000 particles on the PRT/BTC market from .00000200 to .00000300 spread at 5 satoshi intervals), price alerts, etc.
I will have this code complete today, then time for more testing and tweaking and build the live infrastructure.
Thought I would post a screenshot so you can see that this stuff is real and not just fluff. Its real. Its coming very soon. This is the first time anyone in the public is seeing this. I have partnered up with a big name in the business.
You'll see how this ties in to Particle when I release the monthly investors guide.
This looks great .. I am signing up day one !
