## Concept

The operational integrity of the [foreign exchange](https://prime.greeks.live/area/foreign-exchange/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) market rests upon a delicate balance of speed, risk, and information. At the heart of this dynamic lies the practice of ‘last look,’ a mechanism whose application has been fundamentally reshaped by the introduction of the [FX Global Code](https://prime.greeks.live/area/fx-global-code/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). To comprehend this influence is to understand the shift from an environment of implicit trust to one demanding explicit, verifiable transparency. The Code functions as a system-wide patch, addressing a critical vulnerability in the market’s operating protocol ▴ the potential for information asymmetry within the final milliseconds of a trade’s life cycle.

Last look is a risk management practice employed by a [liquidity provider](https://prime.greeks.live/area/liquidity-provider/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (LP) after receiving a trade request from a client, or [liquidity consumer](https://prime.greeks.live/area/liquidity-consumer/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (LC). It grants the LP a brief window of time to conduct final validity and price checks before accepting or rejecting the transaction at the quoted price. In its intended form, this mechanism protects the LP from technological errors, stale quotes, or sudden, adverse price movements that could occur in the time it takes for a request to travel from the client’s system to the LP’s. This protective function is essential in a market characterized by high-frequency quoting and decentralized liquidity, where price updates are constant and latency is a physical reality.

The core issue addressed by the FX Global Code stems from the potential for this protective mechanism to be used for purposes beyond its original design. Before the Code established a clear set of principles, the [last look window](https://prime.greeks.live/area/last-look-window/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) could become an opaque environment where an LP might leverage the information contained within a client’s [trade request](https://prime.greeks.live/question/what-are-the-core-differences-between-a-request-for-quote-and-a-request-for-market/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for its own benefit. For instance, an LP could observe a large buy order, use that information to hedge its own position in the market, and then reject the client’s original trade if the market moved against the client.

This practice, a form of front-running, creates [information leakage](https://prime.greeks.live/question/how-can-a-leakage-model-differentiate-between-market-impact-and-systemic-information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and can result in significant negative market impact for the client, eroding trust in the [electronic trading](https://prime.greeks.live/area/electronic-trading/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) process. The client’s intention is exposed to the market without their trade ever being executed, leaving them to pursue their order at a potentially worse price.

> The FX Global Code re-engineers last look from a private risk option for liquidity providers into a transparent and auditable control mechanism for the entire market.

The FX Global Code emerged as a global initiative by central banks and market participants to establish a common set of guidelines for the wholesale FX market. It is a principles-based framework, not a set of legally binding rules, a design choice intended to make its tenets harder to arbitrage than prescriptive regulations. The Code’s influence on last look is primarily articulated through its [Principle 17](https://prime.greeks.live/area/principle-17/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), which explicitly states that if last look is utilized, it should function as a risk control mechanism for verifying the validity and price of a trade. This principle, supported by detailed guidance from the [Global Foreign Exchange Committee](https://prime.greeks.live/question/how-do-hft-strategies-differ-in-equity-versus-foreign-exchange-markets/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (GFXC), fundamentally alters the permissible application of last look, shifting the operational paradigm toward fairness, transparency, and accountability.

The Code mandates a new level of clarity. LPs who employ [last look](https://prime.greeks.live/area/last-look/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) are expected to be transparent about its use and provide comprehensive disclosures to their clients. This directive moves the practice out of the shadows and into the light of day, making it a quantifiable and comparable element of an LP’s service offering.

It compels a systemic change, forcing LPs to redefine their [risk management](https://prime.greeks.live/area/risk-management/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) procedures and providing clients with the tools to conduct meaningful [due diligence](https://prime.greeks.live/area/due-diligence/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). The Code’s intervention transforms last look from a potential source of conflict into a clearly defined component of the trading relationship, subject to scrutiny and analysis.

## Strategy

The FX Global Code compels both [liquidity providers](https://prime.greeks.live/area/liquidity-providers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and consumers to adopt more sophisticated strategies regarding the application and evaluation of last look. The Code’s principles, particularly Principle 17, serve as the foundation for a new strategic framework built on [transparency](https://prime.greeks.live/area/transparency/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and accountability. This framework forces a recalibration of how LPs manage risk and how LCs select and monitor their counterparties.

## Liquidity Provider Strategic Adjustments

For liquidity providers, the primary strategic shift is from opacity to structured transparency. The Code necessitates a move away from using last look as a discretionary, catch-all tool for revenue optimization toward employing it as a clearly defined and justifiable [risk control](https://prime.greeks.live/area/risk-control/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This requires significant adjustments in operational strategy and technology.

- **Systematic Disclosure** ▴ LPs are now guided to provide clear, detailed, and easily accessible information about their last look policies. The GFXC has developed standardized [Disclosure Cover Sheets](https://prime.greeks.live/question/what-are-the-primary-differences-between-the-cover-1-and-cover-2-standards/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to facilitate this, allowing for greater comparability across providers. This strategic disclosure includes critical details such as the length of the last look window and the methodology of the [price check](https://prime.greeks.live/area/price-check/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

- **Price Check Symmetry** ▴ A crucial element of this disclosure is whether the price check is applied symmetrically or asymmetrically. An asymmetric check means an LP might reject a trade if the [price moves](https://prime.greeks.live/question/how-can-transaction-cost-analysis-distinguish-between-temporary-price-impact-and-permanent-information-based-price-moves/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) against them but accept it if the price moves in their favor. A symmetric check involves rejecting trades if the price moves by a certain threshold in either direction. Disclosing this practice allows clients to assess the fairness of the mechanism and its potential impact on [their execution quality](https://prime.greeks.live/question/how-can-firms-leverage-their-mifid-ii-audit-trail-data-for-improved-execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

- **Refined Risk Architecture** ▴ LPs must re-architect their risk management systems. Instead of relying on last look to absorb all short-term market risk, they must invest in more sophisticated pricing engines and latency management to minimize the need for rejections. The Code effectively raises the bar, pressuring LPs to compete on the quality of their technology and risk modeling, rather than on the aggressive application of last look.

## Liquidity Consumer Strategic Empowerment

The FX Global Code empowers [liquidity consumers](https://prime.greeks.live/question/what-are-the-specific-operational-challenges-of-managing-liquidity-in-a-liquidity-hub-model/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) by providing them with the information and framework needed to conduct rigorous due diligence and optimize [their execution](https://prime.greeks.live/question/how-can-institutional-traders-quantify-the-true-cost-of-information-leakage-in-their-execution-strategies/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) strategies. An LC’s strategy is no longer passive; it is an active process of evaluation and selection.

- **Informed Counterparty Analysis** ▴ Using the standardized disclosures, LCs can perform a comparative analysis of different LPs’ last look policies. This transforms the selection process from one based solely on quoted spreads to a more holistic evaluation that includes the quality and fairness of execution.

- **[Transaction Cost Analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA)** ▴ LCs can and should enhance their TCA frameworks to specifically monitor the impact of last look. This involves tracking not just fill rates but also rejection rates, the [market impact](https://prime.greeks.live/area/market-impact/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) following a rejection, and the hold times associated with last look windows. Analyzing this data reveals the true cost of trading with a particular LP.

- **Engaged Dialogue** ▴ The Code encourages a more interactive relationship between LCs and LPs. LCs are expected to use the data they gather to ask pointed questions about an LP’s last look process and to challenge practices that seem unfair or opaque. This dialogue fosters a market where best practices are rewarded with order flow.

## How Does Transparency Alter the Execution Strategy?

Transparency fundamentally alters execution strategy by turning a hidden variable into a known one. When an LC can clearly see the rules of engagement for last look, they can adjust their own behavior. For instance, a client might use smaller order sizes or route orders through algorithms that are designed to minimize information leakage when dealing with an LP known for longer last look windows. Conversely, an LC might choose to direct more significant flow to LPs who offer no last look or have very short, symmetric last look windows, rewarding them for their transparency.

## Execution

The execution of last look under the FX Global Code is a matter of precise operational protocols and data-driven oversight. The Code’s principles translate into tangible requirements for how liquidity providers must design their trading systems and how liquidity consumers should analyze their execution quality. The focus is on creating a transparent, auditable trail for every trade request subject to a last look review.

![A dark, transparent capsule, representing a principal's secure channel, is intersected by a sharp teal prism and an opaque beige plane.

## The Anatomy of a Code-Compliant Last Look Window

The execution of a trade subject to last look follows a distinct sequence of events. Under the FX Global Code, each step is governed by the principles of transparency and fairness.

- **Trade Request Initiation** ▴ A liquidity consumer sends a trade request to an LP, typically via an electronic trading platform. This request is based on a price quoted by the LP.

- **Last Look Window Commences** ▴ Upon receipt of the request, the LP’s system initiates the last look window. The duration of this window should be disclosed to the client in the LP’s disclosure documents.

- **Validity and Price Check** ▴ The LP’s system performs its risk control checks.

<li>**Validity Check** ▴ This ensures the request is technically sound, with correct currency pairs, notional amounts, and settlement instructions. It also serves as a credit check against the client.

- **Price Check** ▴ The system compares the [quoted price](https://prime.greeks.live/question/what-are-the-primary-drivers-for-a-dealers-quoted-price-in-an-rfq-auction/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) in the client’s request against the current market price available to the LP. The tolerance for [price movement](https://prime.greeks.live/question/how-can-institutions-differentiate-between-price-reversion-and-trading-along-a-genuine-price-trend/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (the threshold that would trigger a rejection) should be applied according to the disclosed symmetric or asymmetric methodology.

</li>
- **Prohibited Activities** ▴ During this window, the Code’s guidance is clear that the LP should not engage in [trading activity](https://prime.greeks.live/question/how-does-high-frequency-trading-activity-affect-the-interpretation-of-post-trade-reversion-signatures/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that utilizes the confidential information from the client’s request. This specifically prohibits the LP from [pre-hedging](https://prime.greeks.live/area/pre-hedging/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) its potential exposure from the client’s trade before deciding whether to accept or reject the request. Such action would signal the client’s intent to the broader market, potentially causing adverse price movement.

- **Acceptance or Rejection** ▴ Based on the outcome of the validity and [price checks](https://prime.greeks.live/question/what-is-the-systemic-impact-of-asymmetric-price-checks-during-the-last-look-window/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), the LP’s system makes a final decision.

<li>**Acceptance** ▴ The trade is filled at the originally quoted price.

- **Rejection** ▴ The trade is rejected. The Code encourages LPs to provide the client with a reason for the rejection and to maintain internal records of these reasons. This provides a crucial data point for the client’s analysis.

</li>
- **Last Look Window Concludes** ▴ The decision is communicated back to the client, and the last look window for that specific trade request is closed.

> A truly compliant execution framework ensures that the last look window is a sterile environment for risk validation, free from any conflicting trading activity.

## The Role of Standardized Disclosures in Execution

The GFXC’s [Disclosure Cover](https://prime.greeks.live/question/what-are-the-primary-differences-between-the-cover-1-and-cover-2-standards/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Sheets are a critical tool in the execution landscape. They are designed to make the “rules of the road” for each LP clear and comparable. For a liquidity consumer’s [trading desk](https://prime.greeks.live/area/trading-desk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), these documents are not mere formalities; they are essential inputs for their execution logic and counterparty risk models.

![A sleek, domed control module, light green to deep blue, on a textured grey base, signifies precision.

## What Is the True Purpose of a Disclosure Cover Sheet?

The true purpose of the [Disclosure Cover Sheet](https://prime.greeks.live/area/disclosure-cover-sheet/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is to democratize information. It levels the playing field by translating complex, often legalistic, disclosure documents into a simple, standardized format. This allows a trading desk to quickly compare the last look policies of multiple LPs and integrate that information into their routing decisions and TCA systems. It moves the market toward a state where LPs compete on the fairness and efficiency of their execution protocols, not on the obscurity of their terms.

![A central metallic bar, representing an RFQ block trade, pivots through translucent geometric planes symbolizing dynamic liquidity pools and multi-leg spread strategies. This illustrates a Principal's operational framework for high-fidelity execution and atomic settlement within a sophisticated Crypto Derivatives OS, optimizing private quotation workflows](https://options.greeks.live/wp-content/uploads/2025/07/institutional-digital-asset-derivatives-rfq-protocol-execution-facilitating-high-fidelity-price-discovery-and-optimal-capital-efficiency-within-advanced-market-microstructure.jpg)

## Data-Driven Execution Analysis for Liquidity Consumers

The Code empowers LCs to become forensic analysts of their own execution data. A sophisticated trading desk should implement a robust TCA process to monitor LPs that use last look. The following table outlines key metrics and their implications.

| TCA Metric | Description | Strategic Implication |
| --- | --- | --- |

By systematically tracking these metrics, a liquidity consumer can move beyond the quoted spread to understand the all-in cost of execution with a given provider. This data-driven approach to execution is the ultimate realization of the FX Global Code’s vision ▴ a market where participants are empowered to make informed decisions and hold their counterparties to the highest standards of conduct.

## Calibrating Your Operational Framework

The integration of the FX Global Code’s principles into the market has provided a new layer of potential transparency. The availability of this data, however, is only the first step. The ultimate responsibility rests within each firm’s operational architecture.

Does your current execution framework possess the analytical capability to process this information effectively? Can your systems distinguish between a legitimate risk control exercised by a counterparty and an exploitative practice that leaks information and increases your trading costs?

Viewing your execution protocol as a dynamic system of intelligence is paramount. The data on rejection rates, [hold times](https://prime.greeks.live/area/hold-times/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), and [post-rejection market impact](https://prime.greeks.live/question/how-can-an-institution-differentiate-between-a-systemic-rejection-and-a-strategic-rejection-from-a-liquidity-provider/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) are more than mere statistics; they are signals about the integrity and efficiency of your counterparties. Integrating these signals into a coherent, automated, and responsive framework for counterparty selection and order routing is what separates a standard execution desk from one that possesses a durable, strategic edge. The Code provides the tools for oversight; the decisive advantage comes from building the system that wields them most effectively.

When an LC can clearly see the rules of engagement for last look, they can adjust their own behavior. For instance, a client might use smaller order sizes or route orders through algorithms that are designed to minimize information leakage when dealing with an LP known for longer last look windows. Conversely, an LC might choose to direct more significant flow to LPs who offer no last look or have very short, symmetric last look windows, rewarding them for their transparency."

It levels the playing field by translating complex, often legalistic, disclosure documents into a simple, standardized format. This allows a trading desk to quickly compare the last look policies of multiple LPs and integrate that information into their routing decisions and TCA systems. It moves the market toward a state where LPs compete on the fairness and efficiency of their execution protocols, not on the obscurity of their terms."
