## Concept

Executing a substantial block of securities without signaling your intent to the broader market is a foundational challenge in institutional trading. The core of this problem resides in the mandatory [pre-trade transparency](https://prime.greeks.live/area/pre-trade-transparency/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) rules established under [MiFID II](https://prime.greeks.live/area/mifid-ii/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), which require venues to display bids and offers. For institutional-scale orders, this transparency creates significant information leakage and the risk of adverse price movement.

The solution lies within the regulatory framework itself, specifically through waivers that permit dark execution for certain types of orders. The two most prominent of these are the [Large-in-Scale](https://prime.greeks.live/area/large-in-scale/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (LIS) and the Size Specific to the Instrument (SSTI) waivers.

The automated selection between these waivers by a trading venue is an exercise in pure computational logic, dictated by regulatory parameters. It is a high-speed, data-dependent process designed to provide a compliant pathway to non-displayed liquidity. A venue’s system does not ‘choose’ a waiver in a subjective sense; it systematically tests an incoming order against a series of predefined, instrument-specific quantitative thresholds. The [LIS waiver](https://prime.greeks.live/area/lis-waiver/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is designed for orders that are unequivocally large in absolute terms, while the [SSTI waiver](https://prime.greeks.live/area/ssti-waiver/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) caters to orders that are large relative to the typical trading size for that specific instrument, a critical distinction for less liquid assets.

The automation is a necessity born from the sheer volume of data and the speed of modern markets. A human trader cannot manually check the real-time liquidity profile, average daily turnover, and specific regulatory thresholds for every single order. The venue’s architecture performs this validation in microseconds, making the process seamless for the end-user but deeply complex in its design.

> The automated selection between LIS and SSTI waivers is a venue’s high-speed, data-driven application of regulatory rules to enable large-scale trading without market-disrupting pre-trade transparency.

## What Defines the LIS and SSTI Waivers?

The Large-in-Scale and Size Specific to the Instrument waivers are distinct mechanisms within the MiFID II/MiFIR framework, each designed to address different facets of institutional liquidity. Understanding their specific triggers is the first step in comprehending the automated logic that governs their use.

- 
**Large-in-Scale (LIS)** This waiver applies to orders that exceed a very high size threshold, defined in absolute monetary values (e.g. euros). These thresholds are set by regulators like [ESMA](https://prime.greeks.live/area/esma/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and vary significantly across different asset classes (e.g. liquid equities, bonds, derivatives). An order qualifies for the LIS waiver simply by being larger than this predefined value. The logic is straightforward ▴ an order of this magnitude is considered inherently disruptive to the market if displayed, justifying its execution in a dark pool or on a waiver-supported system. 

- 
**Size Specific to the Instrument (SSTI)** This waiver is more nuanced. It is designed for [non-equity instruments](https://prime.greeks.live/area/non-equity-instruments/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) like bonds and derivatives. An order qualifies for the SSTI waiver if its size is significant relative to the normal market size for that particular instrument. The calculation is based on percentiles of the distribution of trade sizes for that instrument’s class.
This mechanism acknowledges that what constitutes a “large” trade in a thinly traded [corporate bond](https://prime.greeks.live/area/corporate-bond/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is vastly different from a large trade in a highly liquid government bond. It provides a dynamic, instrument-relative path to dark execution.

The automation engine at a trading venue must therefore have access to a constantly updated repository of these thresholds for every single instrument it trades. This data, provided by regulators, forms the bedrock of the selection process. The venue’s primary responsibility is to correctly classify an incoming order and apply the appropriate threshold test without error or delay.

## Strategy

The strategy behind a venue’s automated [waiver selection](https://prime.greeks.live/question/what-was-the-precise-impact-of-the-lis-waiver-exemption-on-block-trading-technology/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is driven by a dual mandate ▴ ensuring absolute [regulatory compliance](https://prime.greeks.live/area/regulatory-compliance/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and creating an efficient, reliable environment for institutional order flow. The system is architected to apply a clear, deterministic hierarchy to the waiver tests. This is not a matter of preference but of logical process.

For an order that could theoretically qualify for multiple waivers, the venue’s system must have a predefined path to follow. This predictability is essential for the [Smart Order Routers](https://prime.greeks.live/area/smart-order-routers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (SORs) of institutional clients, which rely on consistent venue behavior to make their own routing decisions.

## The Implicit Hierarchy of Waivers

In practice, trading venues design their systems with an implicit order of operations. When an order arrives at the venue’s gateway, the system’s first task is to determine which waivers are potentially applicable based on the instrument type. For non-equity instruments, both LIS and SSTI might be options. The system then proceeds with a sequence of tests.

Generally, the LIS test is prioritized. The rationale is that the LIS waiver is the most unambiguous and highest-level exemption. An order that meets the LIS criteria is definitively large and its eligibility is clear-cut. If the [order size](https://prime.greeks.live/area/order-size/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is greater than or equal to the [LIS threshold](https://prime.greeks.live/area/lis-threshold/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for that instrument, the system flags the order for LIS execution and the process concludes.

The order is passed to the matching engine with the LIS waiver attribute. If the order fails the LIS test, the logic proceeds to the next test in the sequence, which would be the SSTI waiver. The system checks if the order’s size meets the [SSTI threshold](https://prime.greeks.live/area/ssti-threshold/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). If it does, it is flagged accordingly. If it fails both tests, the order cannot be executed under these waivers and may be rejected or routed to a lit book, depending on the client’s instructions.

> Venues strategically prioritize the LIS waiver test due to its unambiguous, high-level criteria, creating a predictable and efficient processing hierarchy for institutional orders.

## How Does a Trader’s Intent Influence the Path?

The trader’s instructions, typically encoded in FIX protocol tags, provide critical input to the venue’s automated system. A trader can specify their execution preferences, which the venue’s logic must respect. For instance, an order might be tagged as “Dark Only.” In this case, if the venue’s waiver engine finds that the order qualifies for neither the LIS nor the SSTI waiver, the order will be rejected. It will not be rerouted to a lit market because doing so would violate the trader’s explicit instructions.

Conversely, a more flexible order might allow for execution in either a dark or lit environment. In this scenario, if the waiver tests fail, the venue’s system could then route the order to its Central Limit Order Book (CLOB) for display and potential execution. This interaction between trader intent and venue logic is a key part of the overall execution strategy.

The table below outlines the core parameters that feed into the automated decision engine, highlighting the distinct data requirements for each waiver.

### Table 1 ▴ Waiver Qualification Data Inputs

| Parameter | LIS (Large-in-Scale) Waiver | SSTI (Size Specific to the Instrument) Waiver |
| --- | --- | --- |
| Applicable Instruments | Equities and Non-Equities (Bonds, Derivatives, etc.) | Non-Equities Only (Bonds, Derivatives, etc.) |
| Primary Threshold Metric | Absolute Notional Value (e.g. €500,000) | Instrument-Relative Size (e.g. 60th percentile of trade sizes) |
| Data Source for Thresholds | ESMA’s transparency calculations, published periodically. | ESMA’s transparency calculations, based on historical trade data for the instrument class. |
| Key System Check | Is Order Size ≥ LIS Threshold? | Is Order Size ≥ SSTI Threshold for this specific instrument? |
| Logical Priority | Typically higher. The system checks for LIS qualification first. | Typically lower. Checked if the LIS test is not met or not applicable. |

## Execution

The execution of the waiver selection logic is a function of the trading venue’s core technological architecture. This process is embedded directly within the order management and matching engine systems. It is designed for extreme low-latency performance, as any delay in processing adds to the risk of market movement.

The entire sequence, from order receipt to waiver determination, must occur in a matter of microseconds. This section details the precise, step-by-step workflow that an order undergoes as it is processed by the venue’s automated system.

## The Automated Selection Workflow

The journey of an institutional order through a venue’s waiver selection engine follows a highly structured and deterministic path. This workflow ensures that every order is treated consistently and in full compliance with MiFID II regulations.

- 
**Order Ingestion and Parsing** An order arrives at the venue’s gateway, typically via the FIX protocol. The system immediately parses the order’s key attributes ▴ the instrument identifier (e.g. ISIN), the order size (quantity and price), and any specific execution instructions (e.g. Time-in-Force, Dark Only flag).

- 
**Static and Dynamic Data Enrichment** The system enriches the order with critical reference data. It pulls the instrument’s asset class, its LIS threshold, and its SSTI threshold from a local, low-latency data cache. This cache is continuously updated with the latest figures from regulatory bodies like ESMA. This step is vital for ensuring the subsequent checks are based on current, accurate data.

- 
**The Waiver Logic Gate** This is the core of the process. The system executes a series of conditional checks in a predefined order:

<li>The system first checks if the instrument is a non-equity. If it is an equity, only the LIS test is relevant.

- **LIS Test** ▴ The system compares the order’s notional value against the stored LIS threshold for that instrument. If Order Value >= LIS Threshold, the order is flagged with the LIS waiver, and the logic sequence terminates for this order.

- **SSTI Test** ▴ If the LIS test fails or is not applicable, and the instrument is a non-equity, the system proceeds to the SSTI test. It compares the order’s size against the stored SSTI threshold. If Order Size >= SSTI Threshold, the order is flagged with the SSTI waiver.

</li>
- 
**Routing and Execution** Once flagged with the appropriate waiver, the order is passed to the venue’s dark matching engine. The waiver flag informs the engine that this order is exempt from pre-trade transparency and can be matched against other dark orders. If no waiver was applied and the order instructions permit, it may be routed to a lit order book.

> The execution of waiver selection is a microsecond-level process where an order is ingested, enriched with regulatory data, and passed through a deterministic logic gate that tests for LIS and then SSTI qualification before execution.

## Is Your Execution Strategy Aligned with Venue Logic?

Understanding the deterministic, automated logic of LIS and SSTI waiver selection is the first layer of analysis. The critical next step is to move from passive knowledge to active strategic application. The architecture of a venue’s waiver engine is not a black box; it is a system with defined rules and predictable outcomes. The question for a sophisticated trading desk is how this understanding should shape the design of its own execution protocols and Smart Order Routers (SORs).

An advanced SOR should do more than simply spray orders to various [dark pools](https://prime.greeks.live/area/dark-pools/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). It should contain a parallel, predictive model of each venue’s waiver logic. Before routing an order, the SOR could pre-calculate the probability of receiving a LIS or SSTI waiver at a given venue based on the order’s specific characteristics.

This allows for more intelligent routing decisions, prioritizing venues where the order has the highest likelihood of being executed quickly and silently under the most favorable waiver. This transforms the trading desk’s posture from being a passive user of venue services to a strategic architect of its own execution outcomes, leveraging the market’s regulatory structure as a tool for achieving capital efficiency and minimizing information leakage.

                "text": "The trader's instructions, typically encoded in FIX protocol tags, provide critical input to the venue's automated system. A trader can specify their execution preferences, which the venue's logic must respect. For instance, an order might be tagged as \"Dark Only.\" In this case, if the venue's waiver engine finds that the order qualifies for neither the LIS nor the SSTI waiver, the order will be rejected. It will not be rerouted to a lit market because doing so would violate the trader's explicit instructions. Conversely, a more flexible order might allow for execution in either a dark or lit environment. In this scenario, if the waiver tests fail, the venue's system could then route the order to its Central Limit Order Book (CLOB) for display and potential execution. This interaction between trader intent and venue logic is a key part of the overall execution strategy."

                "text": "Understanding the deterministic, automated logic of LIS and SSTI waiver selection is the first layer of analysis. The critical next step is to move from passive knowledge to active strategic application. The architecture of a venue's waiver engine is not a black box; it is a system with defined rules and predictable outcomes. The question for a sophisticated trading desk is how this understanding should shape the design of its own execution protocols and Smart Order Routers (SORs)."
