We love the transparency and features of Collective2’s web site, and its integrity as an organization. We love the fact that C2 is a technical website, and not a “dumbed down” mainstream consumer portal. Everything — from The Grid, to writing queries using C2 Explorer — is designed for trading professionals.

It's a great platform. It's great on a couple of levels. For strategy managers, it's a way to prove your value in a verifiable, trusted way. For investors, it's a way to find strategies that are compatible with your risk tolerance and profit objectives. And I just love, love, love its radical transparency. Everything is just out there for people to see, and to study.

Collective2 lets the numbers speak for themselves. There’s really no better way for a trader to get noticed, and to do it on a trusted, verifiable platform. C2 is a great place to launch a career in the financial industry. And for subscribers, it’s a great place to find tomorrow’s stars before they become stars.

The C2 team is professional and courteous, and the AutoTrade technology works brilliantly. I recently personally experienced this when I signed up to use Interactive Brokers, and I linked it to my Collective2 account: executions happen almost instantly, at nearly identical prices to the models. Overall, the platform is amazing. The statistics are deep and useful, the layout is clean and easy to use.

I really admire what Collective2 has built. As an IT professional, I can see that it’s an immense accomplishment — an entire middleware stack connecting trading strategies to brokers. It’s really well-done, and I’m glad to be a part of it.
