There is a fledgling Hacker-News-for-quants at http://quant.ly.

The site is still building critical mass, but most of the current users are experienced quants & HF traders. (Disclaimer: I launched the site)

I nearly launched quantly.com a year ago. Almost bought the .ly but held off on it. Surprising to see someone using the domain here.

Great site. OP might find http://collective2.com interesting as well. Lots of medium-frequency algorithms that might be more accessible if you can't pay big bucks to colo.

Thanks for sharing. Have you subscribed to any strategies?

[SkyMarshal]

No, I was playing around with creating some basic strategies a while back using MetaTrader4 (http://www.metatrader4.com/) to see how it works when I discovered that site. Never got around to trying other peoples'.
