Smart monitoring and trading (automatic price-condition limit orders, no take-profit/stop-loss support)
Order management and amendment (price updates, cancellations, fill verification, cost-basis checks, swaps)

Domain Knowledge

Tool Mapping by Domain

| Group | Tool Calls (jsonrpc: call.method) | |------|------| | Account and balances | get_spot_accounts | | Place/cancel/amend orders | create_spot_order, cancel_all_spot_orders, cancel_spot_order, amend_spot_order | | Open orders and fills | list_spot_orders, list_spot_my_trades | | Market data | get_spot_tickers, get_spot_order_book, get_spot_candlesticks | | Trading rules | get_currency, get_currency_pair | | Fees | get_wallet_fee |

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 (such as "buy 2% lower" or "sell when +500") are implemented by calculating a target price and placing a limit order; no background watcher process is used.
Take-profit/stop-loss (TP/SL) is not supported: do not create trigger orders and do not execute automatic TP/SL at target price.

Market Order Parameter Extraction Rules (Mandatory)

When calling 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:

Buy (market/limit/full-balance buy)
Sell (full-position sell/conditional sell)
Account query (total assets, balance checks, tradability checks)
Order management (list open orders, amend, cancel)
Post-trade verification (filled or not, credited amount, current holdings)
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:

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

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

Before every create_spot_order, always provide an Order Draft first, then wait for explicit confirmation.

Required execution flow:

Send order draft (no trading call yet)
Wait for explicit user approval
Only after approval, submit the real order
Without approval, perform query/estimation only, never execute trading
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 create_spot_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), require confirmation for each leg separately before each create_spot_order.

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: get_spot_accounts
Rule validation: get_currency_pair
Live price and moves: get_spot_tickers
Order placement: create_spot_order
Cancel/amend: cancel_all_spot_orders / cancel_spot_order / amend_spot_order
Open order query: list_spot_orders (use status=open)
Fill verification: list_spot_my_trades

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

Case Routing Map (1-25)

A. Buy and Account Queries (1-8)

| Case | User Intent | Core Decision | Tool Sequence | |------|----------|----------|----------| | 1 | Market buy | Place market buy if USDT is sufficient | get_spot_accounts → create_spot_order | | 2 | Buy at target price | Create a limit buy order | get_spot_accounts → create_spot_order | | 3 | Buy with all balance | Use all available USDT balance to buy | get_spot_accounts → create_spot_order | | 4 | Buy readiness check | Currency status + min size + current unit price | get_currency → get_currency_pair → get_spot_tickers | | 5 | Asset summary | Convert all holdings to USDT value | get_spot_accounts → get_spot_tickers | | 6 | Cancel all then check balance | Cancel all open orders and return balances | cancel_all_spot_orders → get_spot_accounts | | 7 | Sell dust | Sell only if minimum size is met | get_spot_accounts → get_currency_pair → create_spot_order | | 8 | Balance + minimum buy check | Place order only if account balance and min_quote_amount are both satisfied | get_spot_accounts → get_currency_pair → create_spot_order |

B. Smart Monitoring and Trading (9-16)

| Case | User Intent | Core Decision | Tool Sequence | |------|----------|----------|----------| | 9 | Buy 2% lower | Place limit buy at current price -2% | get_spot_tickers → create_spot_order | | 10 | Sell at +500 | Place limit sell at current price +500 | get_spot_tickers → create_spot_order | | 11 | Buy near today's low | Buy only if current price is near 24h low | get_spot_tickers → create_spot_order | | 12 | Sell on 5% drop request | Calculate target drop price and place sell limit order | get_spot_tickers → create_spot_order | | 13 | Buy top gainer | Auto-pick highest 24h gainer and buy | get_spot_tickers → create_spot_order | | 14 | Buy larger loser | Compare BTC/ETH daily drop and buy the bigger loser | get_spot_tickers → create_spot_order | | 15 | Buy then place sell | Market buy, then place sell at +2% reference price | create_spot_order → create_spot_order | | 16 | Fee estimate | Estimate total cost from fee rate and live price | get_wallet_fee → get_spot_tickers |

C. Order Management and Amendment (17-25)

| Case | User Intent | Core Decision | Tool Sequence | |------|----------|----------|----------| | 17 | Raise price for unfilled order | Confirm how much to raise (or target price), locate unfilled buy orders, confirm which order to amend if multiple, then amend limit price | list_spot_orders(status=open) → amend_spot_order | | 18 | Verify fill and holdings | Last buy fill quantity + current total holdings | list_spot_my_trades → get_spot_accounts | | 19 | Cancel if not filled | If still open, cancel and then recheck balance | list_spot_orders(status=open) → cancel_spot_order → get_spot_accounts | | 20 | Rebuy at last price | Use last fill price, check balance, then place limit buy | list_spot_my_trades → get_spot_accounts → create_spot_order | | 21 | Sell at break-even or better | Sell only if current price is above cost basis | list_spot_my_trades → get_spot_tickers → create_spot_order | | 22 | Asset swap | Estimate value, if >=10U then sell then buy | get_spot_accounts → get_spot_tickers → create_spot_order(sell) → create_spot_order(buy) | | 23 | Buy if price condition met | Buy only when current < 60000, then report balance | get_spot_tickers → create_spot_order → get_spot_accounts | | 24 | Buy on trend condition | Buy only if 3 of last 4 hourly candles are bullish | get_spot_candlesticks → create_spot_order | | 25 | Fast-fill limit buy | Use best opposite-book price for fast execution | get_spot_order_book → create_spot_order |

Judgment Logic Summary

| Condition | Action | |-----------|--------| | User asks to check balance before buying | Must call 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 | Clearly state TP/SL is not supported; provide manual limit alternative | | Any order placement request | Require explicit final user confirmation before 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 create_spot_order | | User asks to amend an unfilled buy order | Confirm price increase amount or exact target price before amend_spot_order | | Multiple open buy orders match amendment request | Ask user to choose which order to amend before executing | | 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 | | Unsupported capability | User asks for TP/SL | Clearly state unsupported, propose manual limit-order workflow | | 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 create_spot_order | | Ambiguous amendment target | Multiple candidate open buy orders | Keep pending and ask user to confirm order ID/row | | 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

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

Workflow B: Cancel Then Rebuy

Cancel all open orders to release funds (Case 6)
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.
