Off-Exchange (Dark Pool) Volume

GetOffExchangeVolume
Read-only

Get weekly off-exchange (dark pool / OTC) trading volume for an exact stock or ETF listing from the FINRA OTC/ATS Transparency data. Each week shows ATS (alternative trading system / dark pool) volume and trade count, non-ATS OTC volume and trade count, and the total off-exchange volume (ATS + non-ATS OTC). The FINRA file does not include consolidated tape volume, so the off-exchange share of total market volume is not reported here; compute that share elsewhere against a consolidated-volume source. Weeks before 2025-08-11 may include volume from a case-variant sibling security because they predate the ordinal FINRA symbol-map fix and can no longer be re-imported from FINRA's rolling source window. FINRA publishes each week on a delay (2 weeks for Tier 1 NMS stocks, longer for other tiers), so the latest week lags today.

TDQS

A4.5/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already indicate read-only and non-destructive behavior, and the description adds substantial behavioral context: the exact data source, the returned fields (ATS/non-ATS volume and trade counts), the consolidated-tape exclusion, the pre-2025-08-11 case-variant sibling risk, and the FINRA reporting delay. This goes well beyond the annotation hints.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the core purpose, then efficiently lists returned fields and important caveats in a few clear sentences. Every sentence adds useful information and there is no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Because there is no output schema, the description appropriately explains what values are returned: ATS volume and trade count, non-ATS OTC volume and trade count, and total off-exchange volume. It also covers key limitations such as missing consolidated-tape share, the symbol-map fix issue, and FINRA's delayed publication, making it complete for invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the schema already documents ticker, startDate, endDate, and maxResults with defaults. The description reinforces weekly granularity and the latest-week lag, but it does not need to restate what the schema already covers.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific verb+resource: it gets weekly off-exchange (dark pool / OTC) trading volume from FINRA OTC/ATS Transparency data for an exact stock or ETF listing. This distinguishes it from sibling volume-related tools like GetShortVolume or GetFailsToDeliver.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives clear context: the tool is for a single listed security's weekly off-exchange volume, notes that the off-exchange share of total market volume must be computed separately, and explains the FINRA publication delay. It does not explicitly name alternative tools or when-not conditions, but the scope is unambiguous.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

B3.4/5.0
Disambiguation4/5

Most tools have clearly distinct purposes, with detailed descriptions that cross-reference related alternatives. A few near-duplicate names could cause misselection, notably SearchDocument versus SearchDocuments and GetCftcPositioning versus GetLatestCftcPositioning.

Naming Consistency5/5

Tool names consistently follow a VerbNoun camelCase pattern: Get for retrievals, Search for discovery, List/Read for document access, and Add/Close/Remove/Update/Watch/Create/Delete for portfolio mutations. Despite the large count, there is no mixing of naming conventions or unpredictable verb styles.

Tool Count1/5

108 tools is an extreme surface area, far beyond the 3-15 well-scoped range and well past the 25+ threshold. Even for a broad financial data platform, this creates a heavy selection burden and substantial context overhead for agents.

Completeness4/5

The server covers an unusually wide domain: prices, fundamentals, SEC filings, options, insider activity, 13F holdings, short interest, macro data, funds, IPOs, and full portfolio lifecycle management. Notable gaps remain, such as a basic company profile/ticker-resolution tool, dividend history, and analyst estimates, so it is not a perfect 5.
