What can I do?

Join us in the movement for markets with integrity, fairness and transparency at IAmAnInvestor.org.

If you're an individual investor and want to trade on IEX, see if your broker is currently connected to IEX. Here is a list of firms who are connected and ready to trade.

If your broker isn't currently connected, contact them to request they route your orders to IEX. Complete this template to automatically generate a form letter you can mail or email to your broker (s). Alternatively, you can call your broker and make the request over the phone.

After you make the request, share your experience with the investing public. Tweet @IEXTrading and include the hash-tag #fairmarkets.

IEX can sit on any broker’s platform, creating a highly effective network that increases the likelihood of finding the other side.

A New Direction in Equity Trading

IEX is a FINRA (www.finra.org) registered broker-dealer and is the first registered Alternative Trading System (ATS) that has been funded exclusively by a group of Mutual Funds, Hedge Funds, Family Offices and Individuals. This unique ownership consortium represents a cross-section of traditional investors who are all dedicated to building a fair and balanced market for all participants.

While IEX has no broker owners, we will have only broker subscribers of our trading platform. This unique separation of ownership and subscribers allows IEX to design a trading venue with the traditional investor's best interest in mind, while continuing to recognize the role of brokers in the investment process.

IEX's broker-neutral ownership removes the limitations of operating a broker-owned venue and will allow our market to balance the needs and interests of our broker subscribers and the investing public through advanced technology, intuitive design, and exacting operational standards.

Technology that protects investors

IEX has created patent-pending technology and infrastructure designed to protect orders from Predatory Trading, a sub-class of High Frequency Trading (HFT), that attempts to identify and disadvantage traditional investor order flow. Despite the reputation that HFT has garnered, there are many HFT strategies which provide a valuable service to the market. Predatory Trading is not one of them...and our plan is to stop it.

The IEX trading platform was built by a team of exchange, ATS, electronic trading, high frequency trading, and market structure experts who have combined their previous experience to design a market that works for investors.
