Key Trading Rules

关键交易规则

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.

交易对使用
```
BASE_QUOTE
```
格式，例如
```
BTC_USDT
```
。
下单前需先检查计价货币（例如USDT）的余额。
基于计价金额的买单必须满足
```
min_quote_amount
```
（通常为10U）。
基于币数量的买卖单必须满足最小数量和精度要求（
```
min_base_amount
```
/
```
amount_precision
```
）。
条件请求（例如“低2%买入”或“涨500卖出”）通过计算目标价格并下达限价订单实现，不使用后台监控进程。
不支持止盈/止损（TP/SL）：请勿创建触发订单，也不要在达到目标价格时自动执行止盈/止损。

Market Order Parameter Extraction Rules (Mandatory)

市价订单参数提取规则（强制要求）

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).

当调用

create_spot_order

且

type=market

时，根据买卖方向填写

amount

：

方向	`amount` 含义	示例
`buy`	计价货币金额（USDT）	“买100U的BTC” → `amount="100"`
`sell`	基础货币数量（BTC/ETH等）	“卖0.01个BTC” → `amount="0.01"`

执行前预检查：

市价买单：验证计价货币余额是否足够覆盖
```
amount
```
（USDT）。
市价卖单：验证基础货币可用余额是否足够覆盖
```
amount
```
（币数量）。

Workflow

工作流

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

当用户提出任何现货交易操作请求时，请遵循以下流程。

Step 1: Identify Task Type

步骤1：识别任务类型

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)

将请求归类为以下六类之一：

买入（市价/限价/全仓买入）
卖出（全仓卖出/条件卖出）
账户查询（总资产、余额检查、可交易性检查）
订单管理（列出未成交订单、修改、取消）
交易后验证（是否成交、到账金额、当前持仓）
组合操作（卖出后买入、买入后下达卖单、基于趋势买入）

Step 2: Extract Parameters and Run Pre-checks

步骤2：提取参数并执行预检查

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")

提取关键字段：

```
currency
```
/
```
currency_pair
```
```
side
```
（
```
buy
```
/
```
sell
```
）
```
amount
```
（币数量）或
```
quote_amount
```
（USDT金额）
```
price
```
或价格条件（例如“较当前价低2%”）
触发条件（仅当条件满足时执行）

当

type=market

时，参数标准化为：

```
side=buy
```
：
```
amount = quote_amount
```
（USDT金额）
```
side=sell
```
：
```
amount = base_amount
```
（基础货币数量）

预检查顺序：

交易对/货币的可交易状态
最小订单金额/数量及精度要求
可用余额是否充足
用户条件是否满足（例如“仅在60000以下买入”）

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

步骤3：下单前必须获得用户最终确认（强制要求）

Before every

create_spot_order

or

create_spot_batch_orders

, 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)

在每次调用

create_spot_order

或

create_spot_batch_orders

之前，必须先提供订单草稿，然后等待用户明确确认。

必填执行流程：

发送订单草稿（暂不调用交易接口）
等待用户明确批准
仅在获得批准后，提交真实订单
未获得批准时，仅执行查询/估算操作，绝不执行交易
确认仅单次有效：完成一次执行后，后续任何订单都需重新请求确认

必填确认字段：

交易对（
```
currency_pair
```
）
买卖方向与订单类型（
```
buy/sell
```
，
```
market/limit
```
）
```
amount
```
的含义与数值
限价（如适用）或定价依据
预计成交情况/预计成本或收益
主要风险提示（例如滑点）

推荐草稿措辞：

订单草稿：BTC_USDT，买入，市价，金额=100 USDT，预计按当前卖价成交，风险：快速波动市场中可能出现滑点。回复“确认订单”以下单。

允许的确认回复（示例）：

```
确认订单
```
、
```
确认
```
、
```
执行
```
、
```
是的，下单
```

硬性限制规则（不可绕过）：

除非用户在紧邻的上一轮对话中明确确认，否则绝不调用
```
create_spot_order
```
。
如果对话主题变更、参数变更或讨论了多个选项，则作废旧确认并请求新的确认。
对于多步骤执行（例如案例15/22），每一步调用
```
create_spot_order
```
前都需要单独确认。

如果用户确认缺失、模糊或否定：

不下单
返回待处理状态并请求明确确认
仅继续执行只读操作（余额检查、市场报价、手续费估算）

Step 4: Call Tools by Scenario

Judgment Logic Summary

判断逻辑汇总

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 requests selected-order batch cancellation	Verify each order id exists/open, present list, and run `cancel_spot_batch_orders` only after user verification
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 `create_spot_batch_orders`
User requests fee comparison for multiple pairs	Use `get_spot_batch_fee` and convert to cost impact with latest prices
User requests account flow for a coin	Use `list_spot_account_book` and then reconcile with `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

条件	动作
用户要求在买入前检查余额	必须先调用 `get_spot_accounts` ；仅当余额充足时才下单
用户指定目标价格买卖	使用 `type=limit` 并采用用户提供的价格
用户要求以当前市价最快成交	优先选择 `market` ；若要求“快速限价”，则使用订单盘最优价格
市价买入（ `buy` ）	用USDT计价金额填充 `amount` ，而非基础货币数量
市价卖出（ `sell` ）	用基础货币数量填充 `amount` ，而非USDT金额
用户请求止盈/止损	明确说明不支持该功能；提供手动限价订单替代方案
任何下单请求	在调用 `create_spot_order` 前必须获得用户明确的最终确认
用户未回复明确确认	保持订单为草稿状态；不执行交易
确认已过期或并非来自上一轮对话	作废该确认并要求重新确认
多步骤交易流程	每一步调用 `create_spot_order` 前都需要单独确认
用户要求修改未成交买单	在调用 `amend_spot_order` 前确认涨幅或确切目标价格
多个未成交买单符合修改请求	要求用户确认修改哪一个订单后再执行
用户请求批量取消指定订单	验证每个订单ID是否存在/未成交，展示列表，仅在用户确认后执行 `cancel_spot_batch_orders`
用户请求市场滑点模拟	使用订单盘深度模拟，对比加权成交价与行情最新价
