滑点分析/执行成本分析助手

SkillCommerce & finance

Your AI can analyze slippage and execution costs for Chinese A-share trades once this skill is added. When you ask about slippage, execution costs, or how far actual fill prices deviated from expected prices, it works through the analysis and reports back. It draws its market data from cn-stock-data.

Available today. Use it from your connected AI after setup.

After adding it, ask your AI to analyze slippage or execution costs on A-share trades. Tell it if you want the results in a formal or brief style.

Then ask your AI: use the 滑点分析/执行成本分析助手 skill

What your AI can do with it

  • Measure slippage on Chinese A-share trades
  • Analyze the execution costs of getting A-share orders filled
  • Show how much actual fill prices deviated from expected prices
  • Pull the market data it needs from cn-stock-data
  • Respond to plain questions mentioning slippage, execution costs, or fill deviations
  • Report results in a formal or brief style

数据获取

通过 cn-stock-data skill 获取数据:

  • 成交记录: 实际成交价格与数量
  • 行情数据: 下单时的市场价格
  • 盘口数据: 买卖盘口深度

分析工作流

Step 1: 滑点计算

  • 滑点 = 实际成交价 - 预期成交价(信号价)
  • 买入滑点:通常为正(成交价高于预期)
  • 卖出滑点:通常为负(成交价低于预期)
  • 百分比滑点 = 滑点 / 预期价格 × 100%

Step 2: 滑点分解

  • 市场冲击滑点:订单本身推动价格
  • 延迟滑点:从信号到执行的时间延迟
  • 价差滑点:买卖价差导致的成本
  • 部分成交滑点:未完全成交的机会成本

Step 3: 滑点统计分析

  • 平均滑点:所有交易的滑点均值
  • 滑点分布:正态/偏态/厚尾特征
  • 滑点与订单特征的关系:大小/方向/时段
  • 滑点的时间模式:开盘/盘中/尾盘差异

Step 4: 滑点优化

  • 限价单vs市价单:限价单降低滑点但增加未成交风险
  • 执行时段优化:选择流动性最好的时段
  • 订单拆分:大单拆小降低冲击滑点
  • 算法执行:使用VWAP/TWAP算法控制滑点

Step 5: 输出报告

输出格式

formal 风格(研报级)

# 滑点分析报告

## 一、滑点统计
| 指标 | 数值 |
|------|------|
| 平均滑点 | 0.08% |

## 二、滑点分解
[冲击/延迟/价差各占比]

## 三、滑点模式
[时段/订单大小的影响]

## 四、优化建议

brief 风格(快速分析)

## 滑点分析速览
- 平均滑点 0.08%
- 主要来源:市场冲击(60%)+价差(30%)
- 开盘时段滑点最大(0.15%)
- 建议:避开开盘15分钟,使用限价单
