Trader Decision v2

get_trader_decision_v2
Read-onlyIdempotent

Return a conservative chart-parity trader decision. V2 combines the candle snapshot contract with freshness and execution-component gates; it returns NO_TRADE while candle direction is unvalidated or canonical server-side order flow is unavailable.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
fNoForward horizon in bars. Only the chart presets 5, 10, 30, and 50 are supported
qNoCandles in the matched pattern. Only the chart presets 3, 5, 8, and 12 are supported
limitNoClosest analogues to list (1-20). Bands and direction always use the chart's 20 neighbours
symbolNoSupported chart symbol: BTCUSDT, ETHUSDT, or SOLUSDTBTCUSDT
anchorTsNoOptional historical replay anchor in Unix milliseconds. Omit for the latest chart candle
intervalNoSupported chart timeframe: 5m, 15m, 1h, 4h, or 1d5m
token_idNoOptional token. No token or payment is needed during the free access experiment.
chart_tokenNoOptional account key; all tools work anonymously during the free access experiment.
includeAnalogueCandlesNoInclude OHLC arrays for every analogue and its continuation. False keeps the response agent-sized

B3.4/5.0
Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so safety is covered. The description adds genuinely new behavior: the tool emits NO_TRADE while candle direction is unvalidated or canonical server-side order flow is unavailable — a substantive gating disclosure that prevents the agent from treating absence of a signal as an error.

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

Conciseness4/5

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

Two dense sentences with the core purpose front-loaded and the NO_TRADE gate second. Jargon like 'candle snapshot contract' and 'execution-component gates' is opaque, but nothing is wasted.

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

Completeness3/5

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

No output schema and nine parameters, so the description should carry more of the return-shape burden than it does. It tells the agent one possible return value (NO_TRADE) but not the structure of a positive decision, which is the main gap for a decision-emitting tool.

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% across all nine parameters, with enums and defaults documented inline (horizon presets, pattern lengths, symbol, interval, anchor timestamp). The description adds no parameter-level syntax or format detail beyond that, so the baseline 3 applies.

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

Purpose4/5

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

States a specific verb and resource — returns a 'conservative chart-parity trader decision' — and clarifies the V2 contract combines the candle snapshot with freshness and execution gates. It stops short of explicitly distinguishing itself from siblings like get_candle_market_snapshot or get_candle_evidence_board, so an agent must infer the boundary.

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

Usage Guidelines2/5

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

No when-to-use or when-not-to-use guidance relative to the ten sibling tools. The only routing hint is a behavioral gate (returns NO_TRADE under certain conditions), which describes output rather than when the agent should choose this tool over get_candle_market_snapshot or search_by_sketch.

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