## Concept

The automation of a [unique transaction identifier](https://prime.greeks.live/area/unique-transaction-identifier/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) within a Financial Information eXchange (FIX) workflow is the foundational act of creating a single, immutable data element that serves as the absolute source of truth for a trade’s entire lifecycle. This identifier, frequently the [ClOrdID](https://prime.greeks.live/area/clordid/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (Tag 11) at inception, is the atomic unit of data integrity. Its automated generation is the system’s first commitment to operational control.

Every subsequent message, from execution report to allocation and clearing, pivots on the integrity of this initial identifier. A failure in its uniqueness or persistence introduces systemic risk, corrupting data downstream and rendering post-trade processes fragile and prone to costly reconciliation failures.

From a systems architecture perspective, the [transaction identifier](https://prime.greeks.live/question/what-is-the-role-of-the-unique-transaction-identifier-in-mitigating-cross-regime-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is the primary key in the distributed database that constitutes the global financial market. It links the parent order to its child executions, connects pre-trade intent with post-trade settlement, and provides the unambiguous reference required for [regulatory reporting](https://prime.greeks.live/area/regulatory-reporting/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and internal audit. The automation process itself involves designing a resilient, high-throughput service capable of generating these identifiers with guaranteed uniqueness, even under extreme market conditions and in the face of system failures. This process removes the variable of human error and replaces it with a deterministic, auditable, and high-performance mechanism.

The quality of this automation directly reflects the firm’s commitment to operational excellence and risk management. It is the digital fingerprint of a single economic event, and its clarity is paramount.

> Automating the generation of a unique transaction identifier is the critical first step in establishing an unbreakable chain of data custody throughout the trade lifecycle.

The challenge extends beyond simple sequential numbering. A robust solution must account for a distributed systems environment where multiple applications, trading desks, or even geographic locations may originate orders simultaneously. The architecture must therefore guarantee global uniqueness across the entire enterprise. This involves sophisticated generation algorithms that often combine elements like a high-resolution timestamp, a server or process ID, a rapidly incrementing [sequence number](https://prime.greeks.live/question/how-does-the-sequence-of-dark-pool-and-rfq-usage-affect-execution-costs/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), and potentially a checksum.

The resulting string is a dense, information-rich artifact that is both unique and, in some designs, traceable to its point of origin. This is the bedrock upon which high-frequency, low-latency trading operations are built. Without it, the entire structure of automated trading and settlement becomes unstable.

## Strategy

Developing a robust strategy for automating [unique transaction identifier generation](https://prime.greeks.live/question/what-is-the-role-of-the-unique-transaction-identifier-in-mitigating-cross-regime-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) within a FIX workflow requires a firm to analyze the trade-offs between centralized, decentralized, and hybrid architectural models. The choice of strategy directly impacts latency, scalability, [fault tolerance](https://prime.greeks.live/area/fault-tolerance/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), and the ease of integration with existing Order Management Systems (OMS) and Execution Management Systems (EMS). Each approach presents a distinct set of operational advantages and architectural complexities.

## Architectural Models for Identifier Generation

The selection of an architectural model is the most critical strategic decision in this process. It dictates how identifiers are created, distributed, and validated across the firm’s trading infrastructure.

## Centralized Generation Strategy

In a centralized model, a single, dedicated service ▴ an “[Identifier Generation](https://prime.greeks.live/question/what-is-the-role-of-the-unique-transaction-identifier-in-mitigating-cross-regime-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Service” (IGS) ▴ is responsible for creating every [unique transaction](https://prime.greeks.live/question/what-is-the-role-of-the-unique-transaction-identifier-in-mitigating-cross-regime-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) ID for the entire firm. When an application needs to submit a new order, it first makes a request to the IGS. The IGS generates a unique ID, records it, and returns it to the application, which then populates the ClOrdID (Tag 11) in the NewOrderSingle (35=D) message.

- 
**Advantages** ▴ This approach guarantees absolute uniqueness across the enterprise. Since one service controls the entire keyspace, the possibility of duplicate identifiers is virtually eliminated. It also simplifies auditing and sequence tracking, as there is a single, authoritative source for all generated IDs.

- 
**Disadvantages** ▴ The IGS can become a single point of failure. If the service goes down, no new orders can be generated, effectively halting all trading. It can also introduce a latency bottleneck, as every order-placing application must make a network call to the IGS before sending the order to the street. This added latency, while potentially small, can be significant for high-frequency or latency-sensitive strategies.

## Decentralized Generation Strategy

A decentralized, or embedded, strategy embeds the identifier [generation logic](https://prime.greeks.live/question/how-does-an-rfq-contribute-to-alpha-generation/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) directly within each trading application. Each instance of an application is responsible for creating its own unique IDs. To ensure global uniqueness, the algorithm within each application must use a combination of factors that are inherently unique to its context.

A common formula for this approach is:

- - - 

Here, the ApplicationID is a unique code assigned to the trading application, the ProcessID is the operating system’s process identifier, the Timestamp is a high-precision Unix timestamp (often to the microsecond), and the SequenceNumber is a counter that increments within that specific process. The combination of these elements produces a high probability of uniqueness.

> The strategic choice between centralized and decentralized identifier generation is a direct trade-off between absolute uniqueness guarantees and minimal latency.

## Hybrid Generation Strategy

The [hybrid model](https://prime.greeks.live/area/hybrid-model/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) seeks to balance the benefits of both centralized and decentralized approaches. In this model, applications generate identifiers locally using a decentralized algorithm, eliminating the latency of a network call for every order. However, to prevent failures and ensure long-term uniqueness, the applications periodically connect to a central service to request a reserved block of sequence numbers or a [unique prefix](https://prime.greeks.live/question/how-can-a-firms-proprietary-order-flow-data-be-used-to-create-a-unique-competitive-advantage-in-an-ml-sor-model/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

For example, an application might start up and request a unique prefix like APP01-NYC-DESK04- from a central registry. It can then append its own timestamp and sequence number to this prefix for extremely fast, local generation, confident that no other application in the firm has been assigned the same prefix.

## How Does This Impact Regulatory Reporting?

The strategy for generating a ClOrdID has direct implications for regulatory compliance. Regulations like [EMIR](https://prime.greeks.live/area/emir/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and SFTR require a Unique Transaction Identifier (UTI) to be reported. While the ClOrdID is an internal-facing identifier, it is often the seed from which the regulatory UTI is derived or is used to link the internal trade record to the reported UTI. A robust and auditable [generation strategy](https://prime.greeks.live/question/how-to-structure-a-yield-generation-strategy-with-rfq/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) ensures that a clear, unbroken lineage exists from the initial client order to the final regulatory report.

For instance, the RegulatoryTradeID (Tag 1903) group in later FIX versions allows for specifying different types of identifiers, linking the internal transaction to identifiers generated by venues or clearing houses. A coherent internal strategy simplifies this mapping process immensely.

## Comparing the Strategic Frameworks

The decision on which framework to adopt depends entirely on the firm’s operational priorities. A [high-frequency trading](https://prime.greeks.live/area/high-frequency-trading/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) firm might prioritize the minimal latency of a decentralized model, whereas a large asset manager might prefer the absolute auditability and control of a [centralized service](https://prime.greeks.live/question/how-does-a-centralized-algorithmic-hedging-service-benefit-both-the-buy-side-and-the-sell-side/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

| Strategic Factor | Centralized Model | Decentralized Model | Hybrid Model |
| --- | --- | --- | --- |
| Latency Impact | Higher (requires network call per ID) | Minimal (local generation) | Low (network call only for prefix/block reservation) |
| Uniqueness Guarantee | Absolute | High (relies on algorithm robustness) | Very High (guaranteed by prefix) |
| Fault Tolerance | Low (single point of failure) | High (failure is isolated to the application) | Moderate (resilient as long as prefix is valid) |
| Scalability | Can be a bottleneck | Highly scalable | Highly scalable |
| Audit & Control | Excellent (single source of truth) | Complex (requires log aggregation) | Good (central registry for prefixes) |

Ultimately, the strategy must support the firm’s core business. The goal is to create a system that is transparent, resilient, and fast enough to provide a competitive edge while ensuring complete data integrity for post-trade and regulatory functions. The identifier is the thread that ties the entire workflow together; the strategy for its creation determines the strength of that thread.

## Execution

The execution of an automated unique [transaction identifier generation](https://prime.greeks.live/question/what-is-the-role-of-the-unique-transaction-identifier-in-mitigating-cross-regime-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) system is a multi-stage engineering project that moves from abstract requirements to a concrete, high-performance [technological architecture](https://prime.greeks.live/area/technological-architecture/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). It requires meticulous planning, robust quantitative analysis, and a deep understanding of the underlying trading systems and FIX protocol mechanics. This is the operational core where strategy is translated into a resilient and auditable system.

## The Operational Playbook

Implementing a firm-wide [identifier generation system](https://prime.greeks.live/question/what-is-the-role-of-the-unique-transaction-identifier-in-mitigating-cross-regime-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is a critical infrastructure project. The following playbook outlines a structured, phase-based approach to guide the process from inception to deployment and maintenance.

- 
**Phase 1 Requirements Gathering and Analysis**

<li>
**Stakeholder Interviews** ▴ Conduct detailed interviews with traders, operations staff, compliance officers, and risk managers. The objective is to understand the precise requirements for identifier format, uniqueness constraints, and the performance characteristics (latency, throughput) demanded by each business unit.

- 
**System Audit** ▴ Catalog every system within the firm that originates orders or requires a unique transaction ID. This includes OMS platforms, EMS applications, algorithmic trading engines, and any manual order entry systems.

- 
**Performance Benchmarking** ▴ Quantify the peak message rates and latency tolerance for the most demanding applications. This data will be critical for designing a system that can perform under stress. For example, determine the maximum orders-per-second generated during market open or major economic news events.

- 
**Regulatory Constraints Analysis** ▴ Document all regulatory requirements for transaction identifiers (e.g. [UTI](https://prime.greeks.live/area/uti/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) under EMIR/SFTR, RegulatoryTradeID usage). The system must be designed to support these data requirements natively.

</li>
- 
**Phase 2 Architectural Design**

<li>
**Model Selection** ▴ Based on the requirements gathered in Phase 1, select the appropriate architectural model ▴ centralized, decentralized, or hybrid. A latency-sensitive HFT desk may require a decentralized approach, while a long-only asset management desk could be served by a centralized service. The firm may even choose a hybrid approach to serve different needs.

- 
**Identifier Schema Definition** ▴ Define the precise format of the [unique identifier](https://prime.greeks.live/question/what-is-the-role-of-the-unique-transaction-identifier-in-mitigating-cross-regime-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). A robust schema might look like – – – –. This provides human-readable context (System and Instance) while ensuring uniqueness through the timestamp and a high-frequency sequence counter.

- 
**API Specification** ▴ If using a centralized or hybrid model, define a clear, low-latency API for requesting identifiers or prefixes. This could be a simple RESTful API over HTTP for less sensitive applications or a high-performance binary protocol over TCP for algorithmic engines.

- 
**Fault Tolerance and Failover Design** ▴ Design the system to withstand failure. For a centralized service, this means having a hot-standby instance in a separate [data center](https://prime.greeks.live/area/data-center/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). For decentralized models, this means ensuring that application restarts do not lead to identifier reuse (e.g. by persisting the last sequence number to disk).

</li>
- 
**Phase 3 Development and Testing**

<li>
**Component Development** ▴ Build the core generation logic and, if applicable, the centralized service and its API. Code should be optimized for performance and memory efficiency.

- 
**Unit and Integration Testing** ▴ Develop a comprehensive suite of tests to verify that the generation logic produces unique IDs under all circumstances. Simulate race conditions, clock drift between servers, and network partitions to ensure the system is resilient.

- 
**Performance Load Testing** ▴ Create a testing harness that simulates the peak message rates identified in Phase 1. Measure the latency and throughput of the system to ensure it meets the required performance benchmarks.

- 
**User Acceptance Testing (UAT)** ▴ Deploy the system to a staging environment and have business users test it with their actual workflows and applications to ensure seamless integration.

</li>
- 
**Phase 4 Deployment and Maintenance**

<li>
**Phased Rollout** ▴ Deploy the new system gradually, starting with less critical or less latency-sensitive applications. This minimizes the risk of a firm-wide outage if unforeseen issues arise.

- 
**Monitoring and Alerting** ▴ Implement comprehensive monitoring for the system. Key metrics to track include generation latency, request throughput, and error rates. Set up automated alerts to notify the technology team of any anomalies.

- 
**Contingency Planning** ▴ Maintain a clear contingency plan. What happens if the primary centralized service fails and the failover does not engage? There must be a documented procedure, even if it involves temporarily reverting to a manual or older system, to ensure business continuity.

</li>

## Quantitative Modeling and Data Analysis

The design of the identifier [generation system](https://prime.greeks.live/guide/the-wheel-strategy-a-perpetual-income-generation-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) must be grounded in [quantitative analysis](https://prime.greeks.live/area/quantitative-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to ensure it meets its core objectives of uniqueness and performance. This involves modeling the identifier’s structure and analyzing its performance under various loads.

## Identifier Structure and Uniqueness Probability

The structure of the identifier is a model designed to minimize the probability of collision (i.e. generating a duplicate ID). Consider the following proposed structure for a decentralized system:

- - - 

The total length is 32 characters. Let’s analyze the “uniqueness space” provided by this model:

- 
**SystemID** ▴ A 4-character alphanumeric code allows for (26+10)^4 = 1,679,616 unique system identifiers. This is more than sufficient for any financial firm.

- 
**ProcessID** ▴ A 4-character hex code representing the OS process ID provides 65,536 unique values.

- 
**Timestamp** ▴ A 17-digit Unix timestamp in microseconds provides uniqueness down to the microsecond level. The primary risk here is clock synchronization.

- 
**Sequence** ▴ A 6-digit sequence number allows for 1,000,000 unique orders to be generated by the same process in the same microsecond. This provides a massive buffer against collisions.

The probability of a collision is infinitesimally small, effectively limited to a scenario where two different processes on the same system are assigned the same ProcessID (highly unlikely) and generate an order in the exact same microsecond, and one process has a clock that is catastrophically skewed. The sequence number provides the final layer of defense.

> A well-modeled identifier structure provides a quantitative guarantee of uniqueness that is essential for high-stakes trading environments.

## Performance and Latency Analysis Table

The following table presents a quantitative analysis of the latency introduced by different generation models under varying load conditions. The data is hypothetical but representative of a real-world performance test.

| Generation Model | Load Condition (Orders/sec) | Average Latency (μs) | 99th Percentile Latency (μs) | Throughput Limit (Orders/sec) |
| --- | --- | --- | --- | --- |
| Decentralized (Embedded) | 1,000 | 0.5 | 1.2 | >1,000,000 |
| Decentralized (Embedded) | 50,000 | 0.6 | 1.5 | >1,000,000 |
| Hybrid (Prefix Requested Hourly) | 1,000 | 0.8 | 2.0 | >1,000,000 |
| Hybrid (Prefix Requested Hourly) | 50,000 | 0.9 | 2.5 | >1,000,000 |
| Centralized (LAN Call) | 1,000 | 150 | 350 | ~200,000 |
| Centralized (LAN Call) | 50,000 | 450 | 1,200 | ~200,000 |
| Centralized (WAN Call) | 1,000 | 5,000 | 15,000 | ~30,000 |
| Centralized (WAN Call) | 50,000 | N/A (System Overload) | N/A (System Overload) | ~30,000 |

This analysis clearly demonstrates the performance superiority of decentralized and hybrid models for latency-sensitive applications. A centralized service accessed over a Wide Area Network (WAN) is unsuitable for high-frequency order flow, as the network latency becomes the dominant factor and the system cannot handle high throughput.

## Predictive Scenario Analysis

To understand the real-world impact of this system, consider the case of a mid-sized quantitative hedge fund, “Helios Capital.” Helios operates multiple automated trading strategies across equities and futures markets, generating up to 20,000 orders per second during peak volatility. Their legacy system for ClOrdID generation was a mix of inconsistent, strategy-specific scripts, leading to frequent post-trade reconciliation headaches and occasional duplicate ID rejections from exchanges.

Helios decided to implement a firm-wide hybrid identifier generation system. Each trading strategy’s process, upon initialization, would contact a central “Prefix Registry” service to be assigned a unique 8-character prefix for the day (e.g. EQS01-01- ).

The strategy would then append its own high-resolution timestamp and an internal sequence number to generate full ClOrdID s locally, incurring zero network latency on the critical path. The Prefix Registry was built with full redundancy, with a hot-standby instance in a secondary data center.

The implementation followed the operational playbook. The initial rollout was for a lower-frequency, end-of-day portfolio rebalancing strategy. This allowed the technology team to validate the system’s stability and monitoring tools in a controlled environment. After two weeks of flawless performance, they began migrating the high-frequency strategies one by one.

Six months after full deployment, a major market event occurred ▴ an unexpected central bank announcement caused a massive spike in volatility. Helios’s systems performed as designed, scaling to a peak of 25,000 orders per second. However, at the peak of the event, the primary data center experienced a partial network outage, causing the active [Prefix Registry service](https://prime.greeks.live/question/what-are-the-most-critical-compensating-controls-for-an-internet-exposed-enterprise-service-bus/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to become unreachable for several trading processes. The system’s fault-tolerant design was put to the test.

The trading applications, unable to reach the primary registry, automatically failed over to the secondary registry in the other data center. The failover process took approximately 500 milliseconds. During this brief interval, the affected strategies paused new order generation, preventing any potential issues. Once connected to the secondary registry, they were assigned new, unique prefixes and resumed trading seamlessly.

A post-mortem analysis revealed the value of the architecture. The operations team was able to reconcile the day’s entire trading volume ▴ over 100 million orders ▴ in under 15 minutes, a process that previously took hours and involved manual intervention. The audit trail was perfect; every single order could be traced from its inception within a specific process to its execution and settlement, linked by the globally unique identifier. The compliance team could respond to a hypothetical regulatory inquiry for a specific trade in seconds.

The cost of the network outage, which could have been catastrophic, was limited to a sub-second pause in trading for a fraction of their strategies. The investment in a robust, automated, and fault-tolerant identifier generation system had paid for itself by preventing a single major operational failure.

## System Integration and Technological Architecture

The heart of this system is its deep integration with the firm’s trading infrastructure and its adherence to the [FIX protocol](https://prime.greeks.live/area/fix-protocol/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). The architecture must be specified with technical precision.

![Intricate mechanisms represent a Principal's operational framework, showcasing market microstructure of a Crypto Derivatives OS.

## FIX Protocol Integration Points

The generated identifier is primarily used to populate specific tags within FIX messages. The correct and consistent use of these tags is paramount.

- 
**Tag 11 ( ClOrdID )** ▴ This is the primary field for the unique identifier on a new order. It must be unique for the trading day for a given client. The automated system ensures it is unique across the entire firm.

- 
**Tag 41 ( OrigClOrdID )** ▴ When sending an Order Cancel/Replace Request (35=G) or Order Cancel Request (35=F), this tag must contain the ClOrdID of the order being modified or canceled. The new ClOrdID (Tag 11) on the replacement order must be unique. The system must provide an easy way to retrieve and manage this lineage.

- 
**Tag 17 ( ExecID )** ▴ This identifier is generated by the executing broker or exchange to uniquely identify an execution. The firm’s systems must be able to receive and store this ID, linking it back to the original ClOrdID.

- 
**Tag 37 ( OrderID )** ▴ This is a unique identifier assigned to the order by the broker. Like the ExecID, it must be captured and linked to the ClOrdID.

- 
**Tag 1903 ( RegulatoryTradeID )** ▴ As part of the RegulatoryTradeIDGrp repeating group, this field is used for reporting identifiers required by regulators. The system should be able to store these external identifiers and associate them with the internal ClOrdID.

## Technological Architecture

For a hybrid model, the architecture consists of two main components ▴ the client-side library and the [central Prefix Registry service](https://prime.greeks.live/question/what-are-the-most-critical-compensating-controls-for-an-internet-exposed-enterprise-service-bus/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

**Client-Side Library (e.g. libGenID.so )**

- 
**Language** ▴ C++ for performance, with wrappers for Java, Python, or other languages used by trading applications.

- 
**Functionality** ▴ 

<li>Manages the connection to the Prefix Registry service.

- Handles failover logic between primary and secondary registries.

- Caches the assigned prefix and persists it locally.

- Contains the core, high-performance function generate_id() which appends the timestamp and sequence number.

- Maintains the sequence number, ensuring it resets appropriately (e.g. daily) and is persisted to prevent reuse after a restart.

</li>

**Prefix Registry Service**

- 
**API** ▴ A simple, high-performance API. For example, a TCP service where the client sends a request with its SystemID and ProcessID, and the server responds with a unique prefix string.

- 
**Database** ▴ A high-availability, low-latency database (e.g. Redis, etcd) to store the assigned prefixes and ensure no duplicates are issued. The database must be replicated across data centers.

- 
**Logic** ▴ The service’s logic ensures that for any given day, a prefix is issued to only one client process. It maintains a record of all issued prefixes for audit purposes.

This detailed execution plan, combining a procedural playbook, quantitative analysis, scenario planning, and specific technological architecture, provides a complete blueprint for automating the generation of a unique transaction identifier. It transforms a potential source of operational risk into a cornerstone of institutional efficiency and control.

## Reflection

The successful implementation of an automated transaction identifier system transcends mere operational improvement. It represents a fundamental shift in how a firm perceives and manages its data architecture. The identifier ceases to be a simple tag on a message; it becomes the genetic code of every transaction, carrying with it an immutable history and a guarantee of integrity. When this system is in place, you should ask a deeper question ▴ what other core business processes are still reliant on fragile, inconsistent data foundations?

Consider the identifier as the foundational layer of an intelligence system. With this layer secured, what can now be built on top of it? Real-time risk aggregation, high-fidelity [transaction cost analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA), and predictive compliance monitoring become not just possible, but substantially more accurate and reliable.

The clarity provided by a single, authoritative identifier for every event allows for the confident automation of processes that were previously deemed too risky or complex. The project’s completion is the start of a new line of inquiry into achieving a truly unified operational framework.

                "text": "The strategy for generating a ClOrdID has direct implications for regulatory compliance. Regulations like EMIR and SFTR require a Unique Transaction Identifier (UTI) to be reported. While the ClOrdID is an internal-facing identifier, it is often the seed from which the regulatory UTI is derived or is used to link the internal trade record to the reported UTI. A robust and auditable generation strategy ensures that a clear, unbroken lineage exists from the initial client order to the final regulatory report. For instance, the RegulatoryTradeID (Tag 1903) group in later FIX versions allows for specifying different types of identifiers, linking the internal transaction to identifiers generated by venues or clearing houses. A coherent internal strategy simplifies this mapping process immensely."
