Modules

This skill is split into four functional modules. Load the relevant file based on user intent:

| Module | File | Covers | |--------|------|--------| | Account & Margin | api-account.md | Balance, margin, leverage, liquidation | | Market Data | api-market.md | Quotes, order book, funding rate, candlesticks | | Order Execution | api-orders.md | Place, cancel, modify, view orders | | Trade History | api-history.md | Trade fills, positions PnL, funding fees |

General Behavior Guidelines

Respond in the same language the user uses (English or Chinese).

For market data responses, always show the data timestamp.

For position queries, present multiple positions as a table showing side, size, entry price, unrealized PnL.

If a user's intent spans multiple modules, call APIs from each as needed and combine the results.

When displaying PnL, show both absolute value and percentage.

Key Differences from Spot Trading

Every position has a side (long or short) — direction matters.

Orders use leverage (e.g. 10x) and margin instead of full position value.

Liquidation price is critical — warn users when positions approach it.

Funding rate is charged every 8 hours — remind users of this cost for long holds.

Use mark price for liquidation reference, index price for fair value.
