FIX protocol and prime-broker access to uranium
Institutions reach markets through the FIX protocol and prime brokers. How FIX API and prime-broker access work, and how institutions connect to trade uranium.
Institutions do not trade most markets through a web page. They connect through a standard messaging protocol and through intermediaries that plug into the systems they already run. Two pieces of that infrastructure are standard. The FIX protocol carries orders between trading systems, and the prime broker gives a fund one point of access for trading, financing, and settlement. Uranium has historically offered neither, which is a large part of why institutional capital has stayed out of the market.
What the FIX protocol is
FIX, the Financial Information eXchange protocol, is the messaging standard used across institutional trading. Order-management systems (OMS) and execution-management systems (EMS) use FIX to send orders, receive fills, and track positions with venues and brokers. FIX 4.4 is one of the most widely deployed versions. A venue that supports it can be reached by most institutions through standard integration rather than a bespoke build.
FIX defines both the message format and the session rules. Each message is a set of numbered tag-value fields, such as the symbol, side, quantity, price, and order type. Equities, fixed income, foreign exchange, and listed derivatives all trade over FIX, so a trading desk's systems already speak it.
How a FIX session works
A FIX connection is a persistent session between two parties. One side acts as the acceptor and the other as the initiator. The venue is usually the acceptor, and trading firms connect to it as initiators.
A typical session runs in four steps.
- Logon. The initiator opens the connection and authenticates with a logon message.
- Heartbeats. Both sides exchange heartbeat messages at a fixed interval, so either side can detect a dropped connection.
- Orders and executions. The firm sends new orders, cancels, and replaces. The venue responds with execution reports for each acknowledgment, fill, and cancellation.
- Sequence recovery. Every message carries a sequence number. After a disconnect, either side can request the messages it missed, so no fill is lost.
Sequence numbers and execution reports are why institutions rely on FIX. Every order has an auditable record that flows straight into the firm's risk and reporting systems.
What a drop copy is
A drop copy is a separate, read-only FIX feed that sends a copy of every execution to a firm's systems of record. Compliance, risk, and operations teams use it to see all trading activity in real time, independently of the trading session that placed the orders. A drop-copy feed cannot place or cancel orders.
Why uranium lacked FIX connectivity
Uranium has had no FIX-connected venue. A firm could not route a uranium order through the same systems that handle the rest of its trading. Each uranium position required a separate, manual, broker-dependent process, outside the firm's normal risk and reporting workflow.
What prime brokerage provides
A prime broker gives an institution a single point of access to trade, finance, and settle across venues and counterparties. Prime brokerage typically bundles the following services.
- Financing, including margin lending against the fund's positions.
- Consolidated custody and reporting, so positions across many venues appear in one place.
- Market access, so the fund does not need a direct relationship with every venue it trades.
Prime-broker access is a standard requirement for an institutional market. Its absence is one of the structural reasons funds have found uranium hard to enter.
How institutions connect to Uranium Digital
Uranium Digital supports the connectivity institutional desks already use.
- FIX 4.4. Participants connect to Uranium Digital over an encrypted FIX 4.4 session, from pre-approved network addresses.
- Prime-broker connectivity. Orders will route through prime brokers into the order-management systems a desk already runs.
- Drop copy. A read-only drop-copy feed sends executions to a firm's systems of record.
- Order types. Market and limit orders, with DAY, immediate-or-cancel, and fill-or-kill time-in-force, and a post-only flag for makers who want to guarantee maker-side fills.
Trades settle through digital warehouse receipts, each backed 1:1 by physical U₃O₈ held at an accredited U.S. conversion facility, with physical settlement on the platform rather than through bilateral negotiation.

FAQ
The FIX protocol, or Financial Information eXchange protocol, is the standard messaging language institutional markets use to send orders, receive fills, and track positions between trading systems. Banks, funds, brokers, and venues use it. A market that supports FIX can be reached by most institutions through their existing order-management systems.
The acceptor is the side of a FIX session that listens for connections, and the initiator is the side that opens the connection and logs on. A trading venue usually acts as the acceptor. On Uranium Digital, participants connect over an encrypted FIX 4.4 session, from pre-approved network addresses.
FIX API access is a direct electronic connection between a trading firm's systems and a venue. Prime-broker access routes the firm's orders and settlement through a prime broker, which also provides financing and consolidated custody. Many institutions use both, depending on the market and the relationship.
A drop copy is a read-only FIX feed that sends a copy of every execution to a firm's systems of record. Compliance, risk, and operations teams use it to monitor trading activity independently of the order-entry session. A drop-copy feed cannot place or cancel orders.
Institutions trade on Uranium Digital through the web platform or connect their own systems through FIX 4.4 over an encrypted session. Prime-broker connectivity, which routes orders through a fund's prime broker into its existing order-management systems, is in testing. A read-only drop-copy feed sends executions to the firm's systems of record.
