Limitless.watchUserPositions() is in core and Python SDK but missing from TypeScript SDK

[realfishsam]

Gap

LimitlessExchange exposes watchUserPositions(callback) — a Limitless-specific WebSocket subscription that streams live updates to the authenticated user's positions. The method is implemented in the Python SDK but is entirely absent from the TypeScript SDK.

Core

File: core/src/exchanges/limitless/index.ts line 483

async watchUserPositions(callback: (data: any) => void): Promise<void>

Delegates to LimitlessWebSocket.watchUserPositions (core/src/exchanges/limitless/websocket.ts line 204). A dedicated example ships at core/examples/api-reference/exchange-specific/limitless-watchUserPositions.ts.

TypeScript SDK

Missing — sdks/typescript/pmxt/client.ts has no watchUserPositions method. The Limitless subclass defined near line 2442 of that file is a constructor-only extension of Exchange with no additional methods. Searching the entire sdks/typescript/ tree for watchUserPositions returns zero results.

Python SDK

Present — sdks/python/pmxt/client.py line 2155:

def watch_user_positions(self, callback: Optional[Any] = None) -> List[Position]

Calls the sidecar's /watchUserPositions endpoint and is part of the Python SDK's public surface.

Evidence

grep -rn "watchUserPositions" sdks/typescript/ returns zero results. grep -n "watch_user_positions" sdks/python/pmxt/client.py returns line 2155. grep -n "watchUserPositions" core/src/exchanges/limitless/index.ts returns line 483. The example file core/examples/api-reference/exchange-specific/limitless-watchUserPositions.ts exists and documents the intended SDK usage pattern.

Impact

TypeScript SDK users building Limitless integrations cannot subscribe to live position updates for the authenticated user. Real-time portfolio dashboards and risk-management tools that react to position changes must either use the Python SDK, poll fetchPositions on a timer, or reach directly into the sidecar WebSocket. The Python SDK parity gap means TypeScript users have a materially reduced Limitless account-streaming experience compared to Python users.
