Spec drift: gemini-titan — /orders/active and /orders/history silently truncate to 50 results (no pagination)

[realfishsam]

Exchange

gemini-titan

Drift Type

changed_params

Severity

MEDIUM — Orders beyond the first 50 are silently dropped for both active orders and order history.

Their Docs

Both POST /v1/prediction-markets/orders/active and POST /v1/prediction-markets/orders/history accept pagination parameters:

• limit (max 100, default 50)
• offset (default 0)

/orders/history also accepts a status filter ("filled" or "cancelled").

Our Cached Spec / Implementation

core/src/exchanges/gemini-titan/fetcher.ts:

• Sends { symbol } body only to /orders/active — no limit/offset
• Sends {} (empty body) to /orders/history — no limit, offset, or status filter

There is no OpenAPI spec for this exchange (see issue #408).

callApi() References at Risk

None — direct HTTP calls.

Hardcoded URL Bypasses

• POST ${this.baseUrl}/v1/prediction-markets/orders/active at fetcher.ts:145–153
• POST ${this.baseUrl}/v1/prediction-markets/orders/history at fetcher.ts:156–161

Impact

Any account with more than 50 active orders or 50 closed orders will silently miss the extras. fetchOpenOrders() and fetchClosedOrders() are both incomplete for active traders.
