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.

Past results are not necessarily indicative of future results.

These results are based on simulated or hypothetical performance results that have certain inherent limitations. Unlike the results shown in an actual performance record, these results do not represent actual trading. Also, because these trades have not actually been executed, these results may have under-or over-compensated for the impact, if any, of certain market factors, such as lack of liquidity. Simulated or hypothetical trading programs in general are also subject to the fact that they are designed with the benefit of hindsight. No representation is being made that any account will or is likely to achieve profits or losses similar to these being shown.

In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk in actual trading. For example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program, which cannot be fully accounted for in the preparation of hypothetical performance results and all of which can adversely affect actual trading results.

Material assumptions and methods used when calculating results

The following are material assumptions used when calculating any hypothetical monthly results that appear on our web site.

Profits are reinvested. We assume profits (when there are profits) are reinvested in the trading strategy.
Starting investment size. For any trading strategy on our site, hypothetical results are based on the assumption that you invested the starting amount shown on the strategy’s performance chart. In some cases, nominal dollar amounts on the equity chart have been re-scaled downward to make current go-forward trading sizes more manageable. In these cases, it may not have been possible to trade the strategy historically at the equity levels shown on the chart, and a higher minimum capital was required in the past.
All fees are included. When calculating cumulative returns, we try to estimate and include all the fees a typical trader incurs when AutoTrading using AutoTrade technology. This includes the subscription cost of the strategy, plus any per-trade AutoTrade fees, plus estimated broker commissions if any.
“Max Drawdown” Calculation Method. We calculate the Max Drawdown statistic as follows. Our computer software looks at the equity chart of the system in question and finds the largest percentage amount that the equity chart ever declines from a local “peak” to a subsequent point in time (thus this is formally called “Maximum Peak to Valley Drawdown.”) While this is useful information when evaluating trading systems, you should keep in mind that past performance does not guarantee future results. Therefore, future drawdowns may be larger than the historical maximum drawdowns you see here.

Trading is risky

There is a substantial risk of loss in futures and forex trading. Online trading of stocks and options is extremely risky. Assume you will lose money. Don’t trade with money you cannot afford to lose.
