Key Trading Rules

• Use BASE_QUOTE format for trading pairs, for example BTC_USDT.
• Check quote-currency balance first before buy orders (for example USDT).
• Amount-based buys must satisfy min_quote_amount (commonly 10U).
• Quantity-based buys/sells must satisfy minimum size and precision (min_base_amount / amount_precision).
• Condition requests may be implemented either as immediate limit-order drafting or as trigger orders, depending on user intent ("if price reaches X then place order").
• Take-profit/stop-loss (TP/SL)-style requests are handled via spot trigger-order tools with explicit trigger and execution parameters.

Market Order Parameter Extraction Rules (Mandatory)

When calling cex_spot_create_spot_order with type=market, fill amount by side:

side	amount meaning	Example
buy	Quote-currency amount (USDT)	"Buy 100U BTC" -> amount="100"
sell	Base-currency quantity (BTC/ETH, etc.)	"Sell 0.01 BTC" -> amount="0.01"

Pre-check before execution:

• buy market order: verify quote-currency balance can cover amount (USDT).
• sell market order: verify base-currency available balance can cover amount (coin quantity).

Workflow

When the user asks for any spot trading operation, follow this sequence.

Step 1: Identify Task Type

Classify the request into one of these six categories:

1. Buy (market/limit/full-balance buy)
2. Sell (full-position sell/conditional sell)
3. Account query (total assets, balance checks, tradability checks)
4. Order management (list open orders, amend, cancel)
5. Post-trade verification (filled or not, credited amount, current holdings)
6. Combined actions (sell then buy, buy then place sell order, trend-based buy)

Step 2: Extract Parameters and Run Pre-checks

Extract key fields:

• currency / currency_pair
• side (buy/sell)
• amount (coin quantity) or quote_amount (USDT amount)
• price or price condition (for example "2% below current")
• trigger condition (execute only when condition is met)

When type=market, normalize parameters as:

• side=buy: amount = quote_amount (USDT amount)
• side=sell: amount = base_amount (base-coin quantity)

Pre-check order:

1. Trading pair/currency tradability status
2. Minimum order amount/size and precision
3. Available balance sufficiency
4. User condition satisfaction (for example "buy only below 60000")

Step 3: Final User Confirmation Before Any Order Placement (Mandatory)

Before every cex_spot_create_spot_order, cex_spot_create_spot_batch_orders, or cex_spot_create_spot_price_triggered_order, always provide an Order Draft first, then wait for explicit confirmation.

Required execution flow:

1. Send order draft (no trading call yet)
2. Wait for explicit user approval
3. Only after approval, submit the real order
4. Without approval, perform query/estimation only, never execute trading
5. Treat confirmation as single-use: after one execution, request confirmation again for any next order

Required confirmation fields:

• trading pair (currency_pair)
• side and order type (buy/sell, market/limit)
• amount meaning and value
• limit price (if applicable) or pricing basis
• estimated fill / estimated cost or proceeds
• main risk note (for example slippage)

Recommended draft wording:

• Order Draft: BTC_USDT, buy, market, amount=100 USDT, estimated fill around current ask, risk: slippage in fast markets. Reply "Confirm order" to place it.

Allowed confirmation responses (examples):

• Confirm order, Confirm, Proceed, Yes, place it

Hard blocking rules (non-bypassable):

• NEVER call cex_spot_create_spot_order, cex_spot_create_spot_batch_orders, or cex_spot_create_spot_price_triggered_order unless the user explicitly confirms in the immediately previous turn.
• If the conversation topic changes, parameters change, or multiple options are discussed, invalidate old confirmation and request a new one.
• For multi-leg execution (for example case 15/22/33), require confirmation for each leg separately before each trading call.

If user confirmation is missing, ambiguous, or negative:

• do not place the order
• return a pending status and ask for explicit confirmation
• continue with read-only actions only (balance checks, market quotes, fee estimation)

Step 4: Call Tools by Scenario

Use only the minimal tool set required for the task:

• Balance and available funds: cex_spot_get_spot_accounts
• Rule validation: cex_spot_get_currency_pair
• Live price and moves: cex_spot_get_spot_tickers
• Order placement: cex_spot_create_spot_order / cex_spot_create_spot_batch_orders
• Trigger-order placement/query/cancel: cex_spot_create_spot_price_triggered_order / cex_spot_list_spot_price_triggered_orders / cex_spot_get_spot_price_triggered_order / cex_spot_cancel_spot_price_triggered_order / cex_spot_cancel_spot_price_triggered_order_list
• Cancel/amend: cex_spot_cancel_all_spot_orders / cex_spot_cancel_spot_order / cex_spot_cancel_spot_batch_orders / cex_spot_amend_spot_order / cex_spot_amend_spot_batch_orders
• Open order query: cex_spot_list_spot_orders (use status=open)
• Fill verification: cex_spot_list_spot_my_trades
• Account change history: cex_spot_list_spot_account_book
• Batch fee query: cex_spot_get_spot_batch_fee

Step 5: Return Actionable Result and Status

The response must include:

• Whether execution succeeded (or why it did not execute)
• Core numbers (price, quantity, amount, balance change)
• If condition not met, clearly explain why no order is placed now

Judgment Logic Summary

Condition	Action
User asks to check balance before buying	Must call cex_spot_get_spot_accounts first; place order only if sufficient
User specifies buy/sell at target price	Use type=limit at user-provided price
User asks for fastest fill at current market	Prefer market; if "fast limit" is requested, use best book price
Market buy (buy)	Fill amount with USDT quote amount, not base quantity
Market sell (sell)	Fill amount with base-coin quantity, not USDT amount
User requests take-profit/stop-loss	Use trigger-order workflow: validate position size, draft TP+SL legs, then place after explicit confirmation
Any order placement request	Require explicit final user confirmation before cex_spot_create_spot_order
User has not replied with clear confirmation	Keep order as draft; no trading execution
Confirmation is stale or not from the immediately previous turn	Invalidate it and require a fresh confirmation
Multi-leg trading flow	Require per-leg confirmation before each cex_spot_create_spot_order
User asks to amend an unfilled buy order	Confirm price increase amount or exact target price before cex_spot_amend_spot_order
Multiple open buy orders match amendment request	Ask user to choose which order to amend before executing
User requests selected-order batch cancellation	Verify each order id exists/open, present list, and run cex_spot_cancel_spot_batch_orders only after user verification
User requests batch amend for open orders	Filter target pair open buy orders (max 5), compute repriced levels, and run cex_spot_amend_spot_batch_orders only after user verification
User requests trigger-order progress	Read one trigger order and compare current ticker price to trigger condition; return numeric distance
User requests trigger-order batch cancellation	Filter trigger orders by pair+side, present cancellation scope, then call cex_spot_cancel_spot_price_triggered_order_list after confirmation
User requests single trigger-order cancellation	Verify order is active/matching intent, then call cex_spot_cancel_spot_price_triggered_order after confirmation
User requests market slippage simulation	Use order-book depth simulation and compare weighted fill vs ticker last price
User requests multi-coin one-click buy	Validate summed quote requirement, then use cex_spot_create_spot_batch_orders
User requests fee comparison for multiple pairs	Use cex_spot_get_spot_batch_fee and convert to cost impact with latest prices
User requests account flow for a coin	Use cex_spot_list_spot_account_book and then reconcile with cex_spot_get_spot_accounts
User amount is too small	Check min_quote_amount; if not met, ask user to increase amount
User requests all-in buy/sell	Use available balance, then trim by minimum trade rules
Trigger condition not met	Do not place order; return current vs target price gap

Example decision_text:

• ✅ Condition met. Your order has been placed.
• 📝 Order draft ready. Reply "Confirm order" to execute.
• ⏸️ No order placed yet: current price is 60200, above your target 60000.
• ❌ Not executed: minimum order amount is 10U, your input is 5U.

Error Handling

Error Type	Typical Cause	Handling Strategy
Insufficient balance	Not enough available USDT/coins	Return shortfall and suggest reducing order size
Minimum trade constraint	Below minimum amount/size	Return threshold and suggest increasing order size
Trigger-order parameter mismatch	Trigger rule/price/side is inconsistent with user intent	Return normalized trigger draft and require user reconfirmation
Missing final confirmation	User has not clearly approved final order summary	Keep order pending and request explicit confirmation
Stale confirmation	Confirmation does not match the current draft or is not in the previous turn	Reject execution and ask for reconfirmation
Draft-only mode	User has not confirmed yet	Only run query/estimation tools; do not call cex_spot_create_spot_order, cex_spot_create_spot_batch_orders, or cex_spot_create_spot_price_triggered_order
Ambiguous amendment target	Multiple candidate open buy orders	Keep pending and ask user to confirm order ID/row
Batch-cancel ambiguity	Some requested order ids are missing/not-open	Return matched vs unmatched ids and request reconfirmation
Batch-amend ambiguity	Candidate order set is unclear or exceeds max selection	Ask user to confirm exact order ids (up to 5) before execution
Order missing/already filled	Amendment/cancellation target is invalid	Ask user to refresh open orders and retry
Market condition not met	Trigger condition is not satisfied	Return current price, target price, and difference
Pair unavailable	Currency suspended or abnormal status	Clearly state pair is currently not tradable

Cross-Skill Workflows

Workflow A: Buy Then Amend

1. Place order with gate-exchange-spot (Case 2/9/23)
2. If still unfilled, amend price (Case 17)

Workflow B: Cancel Then Rebuy

1. Cancel all open orders to release funds (Case 6)
2. Re-enter with updated strategy (Case 1/2/9)

Safety Rules

• For all-in/full-balance/one-click requests, restate key amount and symbol before execution.
• For condition-based requests, explicitly show how the trigger threshold is calculated.
• If user asks for TP/SL, do not pretend support; clearly state it is not supported.
• Before any order placement, always request explicit final user confirmation.
• Without explicit confirmation, stay in draft/query/estimation mode and never execute trade placement.
• Do not reuse old confirmations; if anything changes, re-draft and re-confirm.
• For fast-fill requests, warn about possible slippage or order-book depth limits.
• For chained actions (sell then buy), report step-by-step results clearly.
• If any condition is not met, do not force execution; explain and provide alternatives.
