## Concept

An institutional [Request for Quote](https://prime.greeks.live/area/request-for-quote/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (RFQ) protocol operates on a foundational premise of managed disclosure. A firm must reveal its trading intention to a select group of [liquidity providers](https://prime.greeks.live/area/liquidity-providers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to receive actionable prices for a large or complex order. This very act of communication, however, creates an inherent vulnerability. The data representing that intention ▴ the instrument, size, and direction ▴ becomes a target.

A breach of the system carrying this data compromises more than a single trade; it exposes strategy, erodes trust in the market-making system, and can lead to significant financial repercussions through [information leakage](https://prime.greeks.live/area/information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and adverse selection. The integrity of the RFQ process is therefore synonymous with the integrity of the information it conveys. Any [security model](https://prime.greeks.live/area/security-model/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) applied to it must recognize that the primary asset being protected is the confidentiality and immutability of the trading intent itself.

A [Zero Trust security model](https://prime.greeks.live/area/zero-trust-security-model/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) fundamentally re-calibrates the approach to securing these sensitive data flows. It operates from a default stance of universal distrust, compelling verification for every interaction within the trading apparatus. This framework discards the legacy concept of a trusted [internal network](https://prime.greeks.live/question/how-should-tca-reports-differentiate-between-internal-system-latency-and-external-network-latency/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), a digital fortress with a hardened perimeter but a soft, vulnerable interior. In the context of an RFQ system, this means that a request from a portfolio manager’s terminal, the transmission of that request to the RFQ platform’s matching engine, and the dissemination of that request to market makers are all treated as distinct, untrusted events that require rigorous, independent verification.

The model assumes that a breach is not a matter of if, but when, and consequently designs the system to contain and neutralize threats by default. Security ceases to be a perimeter and becomes a granular, pervasive attribute of the data and the workload itself.

> A Zero Trust model redefines security from a static network perimeter to a dynamic, identity-centric enforcement of policy for every single transaction.

This approach directly confronts the specific risks of a bilateral price discovery mechanism. The value of an RFQ lies in its discretion. A Zero Trust framework enforces this discretion at a programmatic level. It is built upon three core pillars that, when integrated into an [RFQ system](https://prime.greeks.live/area/rfq-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), transform its [security posture](https://prime.greeks.live/area/security-posture/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) from passive defense to active, continuous enforcement.

These pillars are ▴ comprehensive identity verification for all actors (human and machine), [micro-segmentation](https://prime.greeks.live/area/micro-segmentation/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to isolate workflows and data, and the principle of least-privilege access to minimize the potential impact of any single compromised component. The successful application of this model means that the security of an RFQ is no longer dependent on the security of the network it traverses, but on the verifiable identity and explicit permissions associated with every stage of its lifecycle.

## The Mandate of Continuous Verification

The foundational principle of “never trust, always verify” is the engine of a [Zero Trust model](https://prime.greeks.live/area/zero-trust-model/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). In an RFQ system, this translates to a continuous cycle of authentication and authorization for every action. When a trader initiates a request for a quote, their identity is verified. The device they use is assessed for its security posture.

The application itself is authenticated as a legitimate workload. This initial check is just the beginning. As the RFQ message moves from the trading desk to the central [RFQ platform](https://prime.greeks.live/area/rfq-platform/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), each service it interacts with ▴ the API gateway, the message bus, the [matching engine](https://prime.greeks.live/area/matching-engine/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) ▴ must re-authenticate and re-authorize the request. This process ensures that a compromised component in the chain cannot be used to gain unauthorized access to other parts of the system. The trust is ephemeral and must be re-established at every transactional boundary.

## Identity as the New Perimeter

In this paradigm, identity becomes the primary control plane. This extends beyond human users with passwords. Every component of the RFQ system, from the front-end user interface to the back-end microservices that connect to liquidity providers, is assigned a strong, cryptographically verifiable identity. These machine identities, often in the form of short-lived digital certificates, are used to establish secure, mutually authenticated communication channels.

An RFQ message is therefore protected not just by network-level encryption, but by application-level identity checks. A request arriving at the matching engine is only processed if it comes from a service with a valid, trusted identity, regardless of its location on the network. This renders many traditional network-based attacks ineffective, as an attacker who gains a foothold on the network still lacks the specific workload identity required to interact with the RFQ system’s core components.

## Micro-Segmentation and Least Privilege Access

The second pillar of the [Zero Trust](https://prime.greeks.live/area/zero-trust/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) framework involves the strategic division of the system into small, isolated zones, a practice known as micro-segmentation. An RFQ system, when viewed through this lens, is not a single application but a collection of discrete services ▴ user authentication, quote request ingestion, liquidity provider routing, quote aggregation, and trade execution reporting. Each of these services resides in its own secure micro-segment, with strict policies governing communication between them. A breach within the user authentication service, for instance, would be contained within that segment.

The attacker would be unable to move laterally to the quote aggregation service because no pre-existing trust relationship exists between these segments. Communication is denied by default and only permitted for specific, authorized purposes.

This structural isolation is complemented by the principle of least-privilege access. Each user and each service is granted the absolute minimum level of permission required to perform its function. A trader may have the rights to initiate an RFQ but not to modify the list of approved liquidity providers. A market data feed service may have the right to push pricing data into the system but not to read pending RFQs.

This granular control dramatically reduces the “blast radius” of a potential breach. An attacker who compromises a single user account or service can only access the limited data and functions associated with that entity. They cannot gain wholesale access to the entire RFQ system, thus preserving the confidentiality of other users’ trading intentions and the overall integrity of the platform.

## Strategy

Implementing a Zero [Trust security model within](https://prime.greeks.live/question/how-can-model-interpretability-in-rfq-systems-build-trader-trust/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) a [Request for Quote system](https://prime.greeks.live/area/request-for-quote-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is a strategic undertaking that re-engineers the flow of information and the nature of trust. It moves security from a peripheral function, managed by firewalls and network administrators, to a core attribute of the trading application itself. The strategy is not about adding more layers of security in a traditional sense, but about weaving a new logic of verification and containment into the very fabric of the RFQ workflow. This requires a shift in perspective, viewing the entire process ▴ from the trader’s initial click to the final settlement instruction ▴ as a series of discrete, verifiable interactions occurring in a potentially hostile environment.

The strategic objective is to create a system where the security of a bilateral price negotiation is guaranteed by the system’s intrinsic design, rather than by assumptions about the network it operates on. This involves a multi-faceted approach that addresses identity, data, workloads, and networks as interconnected elements of a unified security posture. The strategy can be broken down into several key initiatives ▴ establishing a universal [identity and access management](https://prime.greeks.live/area/identity-and-access-management/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (IAM) framework, implementing a comprehensive micro-segmentation architecture, enforcing data-centric protection policies, and leveraging advanced analytics for continuous threat detection. Each of these initiatives directly mitigates specific risks associated with RFQ system breaches, such as information leakage, data tampering, and denial of service.

## A Universal Framework for Identity

The cornerstone of a Zero Trust strategy for an RFQ system is a universal IAM framework that treats every entity ▴ human and machine ▴ as an identity to be managed and verified. This goes far beyond traditional username and password combinations. For human users, such as traders and operations staff, the strategy mandates the use of strong multi-factor authentication (MFA) as a baseline.

Access decisions are then enriched with contextual data, such as the user’s location, the time of day, and the security posture of their device. A request to initiate a high-value RFQ from an unrecognized device or an unusual geographic location could trigger a requirement for additional verification or be blocked entirely.

For machine identities, the strategy calls for the adoption of a [service mesh](https://prime.greeks.live/area/service-mesh/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) architecture. A service mesh provides a dedicated infrastructure layer for managing [service-to-service communication](https://prime.greeks.live/area/service-to-service-communication/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), separate from the application code. Within this mesh, every microservice in the RFQ platform is assigned a strong, rotatable identity (typically using a standard like SPIFFE). All communication between services is then forced through an encrypted and mutually authenticated tunnel (mTLS).

This means that the service responsible for ingesting RFQs from traders will only accept connections from an [API gateway](https://prime.greeks.live/area/api-gateway/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that can present a valid cryptographic identity. This approach effectively eliminates the risk of an attacker spoofing a service or intercepting data within the platform’s internal network.

> The strategic application of Zero Trust ensures that a compromised network position does not automatically grant access to sensitive RFQ data flows.

This universal identity framework directly mitigates the risk of unauthorized access. An attacker who steals a trader’s password would still be thwarted by MFA. An attacker who compromises a web server on the network perimeter would be unable to interact with the core RFQ services because their compromised process would lack the necessary machine identity. The system’s trust boundary is redrawn around individual identities, making it far more resilient to the [lateral movement](https://prime.greeks.live/question/how-can-quantitative-models-differentiate-between-coincidental-market-movement-and-actual-dealer-front-running/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) techniques commonly used by attackers.

## Comparative Security Postures

The strategic shift from a traditional, perimeter-based model to a Zero [Trust model](https://prime.greeks.live/question/how-can-model-interpretability-in-rfq-systems-build-trader-trust/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) can be illustrated by comparing their respective approaches to securing an [RFQ workflow](https://prime.greeks.live/area/rfq-workflow/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). The following table outlines these differences, highlighting the superior resilience of the Zero Trust approach against common attack vectors.

| Security Domain | Traditional Perimeter-Based Model | Zero Trust Model |
| --- | --- | --- |
| Access Control | Relies on network location (e.g. inside vs. outside the firewall). Once inside, trust is often implicit. | Relies on verified identity of the user and device, regardless of network location. Trust is never implicit. |
| Internal Traffic | Often uninspected and unencrypted, assuming the internal network is “safe.” | All service-to-service communication is encrypted and mutually authenticated (mTLS). Lateral movement is difficult. |
| Authentication | Primarily focused on initial login, often with single-factor authentication. | Continuous authentication and authorization for every request. Multi-factor authentication is standard. |
| Breach Impact | A single breach of the perimeter can lead to widespread access and data exfiltration. | Breaches are contained within small micro-segments, limiting the “blast radius.” |
| Policy Enforcement | Policies are enforced at large network chokepoints (firewalls, routers). | Policies are granular and enforced at the individual workload or application level. |

## Systemic Isolation through Micro-Segmentation

A core strategic element is the aggressive use of micro-segmentation to dismantle the concept of a monolithic RFQ application. The system is architecturally decomposed into its smallest functional units. For example:

- **User Interface Gateway** ▴ The service that traders’ front-end applications connect to.

- **RFQ [Ingestion 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)** ▴ Responsible for validating and accepting new quote requests.

- **Counterparty Selection Engine** ▴ A service that determines which liquidity providers should receive a given RFQ based on pre-defined rules.

- **Quote Aggregation Service** ▴ Collects incoming quotes from liquidity providers.

- **Execution Service** ▴ Handles the acceptance of a winning quote and communicates with downstream order management systems.

Each of these components is deployed in its own isolated network environment. A central [policy engine](https://prime.greeks.live/area/policy-engine/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) defines the allowed communication paths. For instance, the User Interface Gateway is permitted to talk to the RFQ Ingestion Service, but it is explicitly forbidden from communicating directly with the Execution Service. This policy is enforced by the service mesh at the infrastructure level.

If an attacker were to find a vulnerability in the gateway, they could not use that position to directly trigger a trade execution. This containment strategy is crucial for mitigating the risks of an RFQ system breach, as it prevents an initial foothold from escalating into a catastrophic failure of the entire trading process.

## A Data-Centric Protection Mandate

The strategy extends beyond network and workload security to focus on the data itself. A Zero Trust approach mandates that [security controls](https://prime.greeks.live/area/security-controls/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) should be attached to the data, traveling with it throughout its lifecycle. For an RFQ system, this means that sensitive information within a quote request ▴ such as the instrument identifier, quantity, and client name ▴ is classified and protected based on its sensitivity. This is achieved through a combination of encryption and data loss prevention (DLP) technologies.

All [RFQ data](https://prime.greeks.live/area/rfq-data/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is encrypted at rest in the database and in transit across the network. More importantly, the DLP system can be configured to understand the structure of an RFQ. It can identify when sensitive RFQ data is being sent to an unauthorized destination, such as a personal email address or a cloud storage service, and block the transmission in real-time.

These policies are enforced regardless of the user or device, ensuring that the data itself is the last line of defense. This data-centric approach provides a powerful safeguard against both malicious insider threats and external attackers who manage to bypass other security controls.

## Execution

The execution of a Zero [Trust security model](https://prime.greeks.live/question/how-can-model-interpretability-in-rfq-systems-build-trader-trust/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) within a live institutional RFQ environment is a complex systems engineering challenge. It requires a disciplined, phased approach that integrates advanced security technologies into the core of the trading infrastructure without compromising the low-latency and high-throughput demands of the business. This is not a simple product installation; it is the re-architecting of a critical system around a new set of principles. The execution phase moves from strategic concepts to the granular details of implementation, focusing on the specific tools, protocols, and operational procedures required to build and maintain a verifiably secure RFQ platform.

The successful execution of this model hinges on a deep understanding of both cybersecurity and market microstructure. The goal is to achieve a state of “secure by design,” where security is an emergent property of the system’s architecture. This involves a meticulous focus on the technical implementation of identity management, the configuration of network and application policies, and the integration of continuous monitoring and response capabilities. The process must be methodical, with clear success metrics at each stage, ensuring that the introduction of new security controls enhances, rather than degrades, the performance and reliability of the RFQ workflow.

## The Operational Playbook for Zero Trust Implementation

Deploying a [Zero Trust architecture](https://prime.greeks.live/area/zero-trust-architecture/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for an RFQ system follows a structured, multi-stage playbook. This process ensures a controlled transition from a traditional security model to a fully-realized Zero Trust environment.

- **Define the [Protect Surface](https://prime.greeks.live/question/how-can-institutions-model-changes-in-the-volatility-surface-for-stress-testing-hedges/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)** ▴ The first step is to identify the most critical data, applications, assets, and services (DAAS) within the RFQ system. This includes the RFQ database, the matching engine, the API gateways connecting to liquidity providers, and the administrative interfaces. This “protect surface” is the focal point of all subsequent security efforts.

- **Map Transaction Flows** ▴ The next step is to meticulously map how data flows through the RFQ system. This involves tracing the path of a quote request from the trader’s desktop, through the internal network, to the liquidity providers, and back again. This mapping exercise identifies all the users, devices, services, and network segments that interact with the protect surface.

- **Architect the Zero Trust Environment** ▴ With a clear understanding of the protect surface and transaction flows, the next stage is to design the Zero [Trust architecture](https://prime.greeks.live/area/trust-architecture/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This involves selecting the specific technologies for identity management (e.g. an OAuth 2.0-based identity provider), service mesh (e.g. Istio or Linkerd), and policy enforcement (e.g. Open Policy Agent). The architecture defines how micro-segments will be created and how policies will be centrally managed and distributed.

- **Create Granular Security Policies** ▴ This is the core of the execution phase. A “whitelist” policy is created that defines precisely who can access what, under which circumstances. These policies are written in a machine-readable format and answer questions like ▴ “Can the RFQ-ingestion service, running in the production environment, initiate a connection to the counterparty-selection-engine on port 443, using a valid mTLS certificate?” All other traffic is denied by default.

- **Implement and Monitor** ▴ The policies and technologies are deployed, initially in a “logging-only” mode. In this mode, the system logs all policy violations without actually blocking them. This allows the security team to refine the policies and identify any legitimate traffic that was not accounted for in the initial mapping phase.

- **Enforce and Maintain** ▴ Once the policies have been validated, the system is switched to full enforcement mode. From this point forward, all unauthorized connection attempts are blocked. The system is continuously monitored, and the policies are regularly reviewed and updated to adapt to changes in the application and the threat landscape.

## Quantitative Modeling and Data Analysis

The effectiveness of a Zero Trust implementation can be quantified by analyzing its impact on both risk posture and system performance. The following tables provide a modeled analysis of these factors. The first table assesses the model’s efficacy in mitigating specific, high-impact threat vectors common to RFQ systems. The second provides a hypothetical performance analysis, acknowledging that security controls introduce latency, which must be measured and managed.

![A segmented circular diagram, split diagonally. Its core, with blue rings, represents the Prime RFQ Intelligence Layer driving High-Fidelity Execution for Institutional Digital Asset Derivatives](https://options.greeks.live/wp-content/uploads/2025/08/high-speed-prime-os-rfq-digital-asset-derivatives-trade-execution.jpg)

## Table 1 Threat Vector Mitigation Efficacy

This table maps common RFQ system attack vectors to the specific Zero Trust controls designed to mitigate them, along with a qualitative assessment of risk reduction.

| Threat Vector | Description | Primary Zero Trust Control | Risk Reduction Assessment |
| --- | --- | --- | --- |
| Information Leakage via Lateral Movement | An attacker breaches a non-critical system and moves through the network to access the RFQ database. | Micro-segmentation and “deny-by-default” network policies. | High. Lateral movement is severely restricted as no implicit trust exists between segments. |
| Insider Threat (Data Exfiltration) | A legitimate user with broad access rights copies and removes sensitive RFQ data. | Least Privilege Access and Data Loss Prevention (DLP) policies. | High. User access is limited to necessary functions, and DLP can block unauthorized data transfers. |
| Man-in-the-Middle (MITM) Attack | An attacker intercepts and potentially alters RFQ traffic between services. | Mutual TLS (mTLS) for all service-to-service communication. | Very High. Strong, identity-based encryption and authentication prevent interception and spoofing. |
| API Key Compromise | An attacker steals a static API key used by a liquidity provider to access the RFQ platform. | Short-lived, dynamically generated tokens (e.g. OAuth 2.0) and strong client authentication. | High. Stolen credentials have a very short lifespan, minimizing the window of opportunity for misuse. |
| Denial of Service (DoS) on Core Engine | An attacker floods the RFQ matching engine with traffic from compromised machines on the internal network. | API Gateway with rate limiting and strong authentication at the network edge. | Medium. While it can mitigate many attacks, sophisticated application-layer DoS may require additional dedicated solutions. |

## Table 2 Hypothetical Performance Impact Analysis

This table presents a modeled analysis of the latency introduced by various Zero Trust components into the critical path of an RFQ’s lifecycle. The data is hypothetical and would vary based on specific implementation choices.

| RFQ Lifecycle Stage | Zero Trust Component | Associated Latency (Microseconds – µs) | Notes |
| --- | --- | --- | --- |
| Trader Submits RFQ | Client-side Device Posture Check | 500 – 1,500 µs | Performed on the trader’s machine before the request is sent. Out of the critical network path. |
| Request Hits API Gateway | MFA Token Validation / JWT Signature Verification | 150 – 300 µs | Hardware-accelerated cryptography can significantly reduce this overhead. |
| Gateway to Ingestion Service | mTLS Handshake (New Connection) | ~5,000 µs | Occurs only on initial connection. Subsequent requests use session resumption (~200 µs). |
| Ingestion Service to Policy Engine | Policy Evaluation Request (Authorization) | 50 – 100 µs | Highly optimized process, often with local caching of policy decisions to reduce network hops. |
| Engine to Liquidity Provider | Outbound API Gateway Policy Check | 50 – 100 µs | Ensures the request is only sent to authorized counterparties. |
| Total Estimated Overhead (Critical Path) | Sum of In-line Components | ~250 – 500 µs | Represents the typical added latency per RFQ transaction, assuming warm connections. |

> The marginal latency introduced by a well-architected Zero Trust model is a quantifiable and acceptable trade-off for the profound reduction in systemic risk.

## System Integration and Technological Architecture

The technological backbone of a Zero Trust RFQ system is a suite of integrated, modern security tools. The architecture is designed to externalize security policy and enforcement from the application code, allowing for greater flexibility and more robust control.

- **Identity Provider (IdP)** ▴ This is the central authority for user and service identity. Solutions like Okta, Azure AD, or open-source alternatives using protocols like OpenID Connect and SAML serve as the single source of truth for authentication. All access requests begin with a token issued by the IdP.

- **Service Mesh (e.g. Istio, Linkerd)** ▴ The service mesh is the enforcement layer for service-to-service communication. It deploys a lightweight proxy (an “envoy” or “sidecar”) alongside each microservice. These proxies intercept all network traffic, enforce mTLS, and communicate with the policy engine to make real-time authorization decisions. This decouples the RFQ application developers from the complexities of implementing security protocols.

- **Policy Engine (e.g. Open Policy Agent – OPA)** ▴ OPA is a general-purpose policy engine that allows security policies to be written as code. These policies are decoupled from the services they govern. The service mesh proxies query OPA to determine if a specific request (e.g. “service A wants to read data from service B”) is allowed. This centralized policy management provides a unified and auditable view of all access controls across the RFQ system.

- **API Gateway** ▴ Positioned at the edge of the network, the API Gateway is the entry point for all external traffic, including requests from traders and liquidity providers. It is responsible for initial authentication, rate limiting, and routing traffic to the appropriate internal services. It acts as the first line of defense, enforcing Zero Trust principles before traffic is even allowed into the core platform.

The integration of these components creates a resilient, self-defending system. An RFQ is submitted to the API Gateway, which validates the trader’s identity token with the IdP. The request is then forwarded into the service mesh.

As it moves from the ingestion service to the matching engine, each service’s proxy sidecar verifies the cryptographic identity of the upstream service and queries the policy engine to ensure the action is authorized. This multi-layered, continuous verification process ensures that even if one component is compromised, the breach is contained and the integrity of the overall RFQ workflow is preserved.

## A Systemic Recalibration of Trust

Adopting a Zero Trust model for a Request for Quote system is ultimately an exercise in systemic recalibration. It forces a fundamental re-evaluation of where trust is placed within a trading architecture. The process moves the locus of trust away from network topology and physical locations, which are inherently fragile and permeable, and places it onto the far more durable and verifiable foundation of cryptographic identity.

The resulting system is one where security is an active, measurable, and continuously enforced property, rather than a passive and hopeful assumption. This architectural integrity becomes a competitive differentiator, enabling firms to engage in sensitive, high-value negotiations with a higher degree of confidence.

The knowledge gained through this implementation extends beyond the mitigation of specific threats. It provides a new lens through which to view all critical trading systems. The principles of explicit verification, systemic isolation, and data-centric protection become core components of an institution’s operational intelligence.

The framework ceases to be merely a security measure and evolves into a platform for building more resilient, auditable, and ultimately more effective mechanisms for accessing liquidity. The final state is a system that is not only secure against external attack but is also internally coherent and logically sound, providing a robust foundation for future innovation in [institutional trading protocols](https://prime.greeks.live/area/institutional-trading-protocols/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).
