# 🎯 EV 期望值计算器
**定价**: 0.01 USDC (x402支付)
**作者**: Rich (@samhuang2025)
---
## 简介
计算交易/投注的期望值(Expected Value),判断是否具有正期望。
**核心功能**:
- ✅ 基础EV计算
- ✅ Polymarket概率计算
- ✅ 赔率转换
- ✅ 套利边界检测
---
## 核心公式
### 基础版
```
EV = p × win - (1-p) × loss
```
- p = 胜率
- win = 赢的金额
- loss = 输的金额
### 简化版(对称盈亏)
```
EV = p × b - (1-p) × 1
```
其中 b = 盈亏比
### Polymarket版
```
EV = 你的概率 - 市场概率
```
---
## 判断标准
| EV值 | 含义 | 行动 |
|------|------|------|
| EV > 0 | 正期望值,能赚 | ✅ 可以玩 |
| EV = 0 | 不亏不赚 | ⚪ 观望 |
| EV < 0 | 负期望值,必亏 | ❌ 不玩 |
---
## 使用方法
### 1. 基础EV计算
```python
def calculate_ev(p, win, loss):
"""
计算期望值
Args:
p: 胜率 (0-1)
win: 赢的金额
loss: 输的金额
Returns:
EV值 (正=赚,负=亏)
"""
return p * win - (1 - p) * loss
```
### 2. Polymarket概率
```python
def polymarket_ev(your_prob, market_price):
"""
计算Polymarket的EV
Args:
your_prob: 你判断的真实概率 (0-1)
market_price: 市场定价 (0-1)
Returns:
edge (你的概率 - 市场概率)
"""
return your_prob - market_price
```
### 3. 盈亏比计算
```python
def win_loss_ratio(win_pct, loss_pct):
"""计算盈亏比"""
return win_pct / loss_pct
```
---
## 实战案例
### 案例1:抛硬币
- 正面赢 $1.10
- 反面输 $1.00
- 概率各 50%
```
EV = 0.5 × 1.10 - 0.5 × 1.00 = +$0.05
```
✅ 每赌一次期望赚5分
### 案例2:Polymarket
- 你判断 Trump 赢 = 60%
- 市场定价 YES = 40%
- 买入成本 = $0.40
```
EV = 0.60 - 0.40 = +0.20 (20% edge)
```
✅ 每投$1期望赚$0.20
### 案例3:彩票套利(Winfall Roll-down)
- 正常时期:期望拿回$0.55
- Roll-down时期:期望拿回$1.18
```
正常EV = 0.55 - 1.00 = -$0.45 (亏)
套利EV = 1.18 - 1.00 = +$0.18 (赚)
```
---
## 快速查询表
### 对称盈亏(赢亏相等)
| 胜率 | EV | 评价 |
|------|-----|------|
| 45% | -10% | 远离 |
| 48% | -4% | 避开 |
| 50% | 0% | 公平 |
| 52% | +4% | 可以 |
| 55% | +10% | 不错 |
| 60% | +20% | 很好 |
| 70% | +40% | 极佳 |
### Polymarket Edge
| 市场定价 | 你的判断 | Edge |
|----------|---------|------|
| 30% | 45% | +15% |
| 40% | 55% | +15% |
| 50% | 65% | +15% |
| 60% | 75% | +15% |

## x402 支付
本skill支持x402微支付协议。调用时自动发起0.01 USDC支付请求。
```bash
# x402支付示例
curl -X POST https://api.x402.dev/pay \
-H "Content-Type: application/json" \
-d '{
"to": "0x24b288c98421d7b447c2d6a6442538d01c5fce22",
"amount": "0.01",
"currency": "USDC",
"memo": "kelly-formula-skill"
}'
```
---
## 核心公式
### 完整版
```
f* = (bp - q) / b
```
- p = 胜率
- b = 盈亏比
- q = 1 - p
### 简化版(对称盈亏)
```
f* ≈ 2p - 1
```
记忆法:胜率高出50%的部分×2 = 建议仓位
---
## 使用方法
### 1. 基本仓位计算
**输入**:
- 胜率 p (0-1)
- 盈亏比 b (如 2.0 表示赚2块亏1块)
**输出**:
- 全凯利仓位
- ½凯利仓位(推荐)
- ¼凯利仓位(保守/杠杆)
```python
def kelly_position(p, b, fraction=0.5):
if p <= 0.5:
return 0 # 无优势,不做
f_star = (p * b - (1 - p)) / b
if f_star < 0:
return 0
return f_star * fraction
```
### 2. 对称速查表
| 胜率 | 全凯利 | ½凯利 | ¼凯利 |
|------|--------|-------|-------|
| 52% | 4% | 2% | 1% |
| 55% | 10% | 5% | 2.5% |
| 60% | 20% | 10% | 5% |
| 65% | 30% | 15% | 7.5% |
| 70% | 40% | 20% | 10% |
| 75% | 50% | 25% | 12.5% |
### 3. 多策略仓位分配
**原则**:相关性>0.7时,合并仓位打7折
```python
def adjusted_position(positions, correlation, discount=0.7):
total = sum(positions)
if correlation > 0.7:
return total * discount
return total
```
### 4. 杠杆安全边际
```python
def leverage_safety(liquidation_distance, stop_loss):
safety_factor = liquidation_distance / stop_loss
if safety_factor < 2:
return "不安全,建议降杠杆"
return "安全"
```
---
## 实战案例
### 案例1:BTC短线趋势
- 胜率 55%,盈亏比 5%/3%
- 净优势 = 0.55×5 - 0.45×3 = 1.4%
- 建议仓位 = 1.4 ÷ 5 = 28%
- 执行½ = 14%
### 案例2:ETH资金费套利
- 胜率 70%,盈亏比 2%/1%
- 净优势 = 1.4 - 0.3 = 1.1%
- 建议仓位 = 55%
- 执行¼-½ = 14-27%
### 案例3:Meme热点
- 表面:胜率58%,盈亏比7%/5%
- 但1/6亏损是-25%插针
- 真实亏损 = 5/6×5% + 1/6×25% = 8.3%
- 新净优势 = 4.06 - 3.49 = 0.57%
- 建议仓位 ≈ 8% → 执行2-4%

## 8条铁律
1. **默认分数凯利**:先用½,带杠杆/不稳用¼
2. **摩擦全进账**:费率、滑点、资金费、Gas全部计入
3. **滚动估参**:月/季更新,重大事件临时降档
4. **三道闸门**:单笔、单日、单策略回撤硬阈值
5. **净敞口上限**:相关性高时顶层总仓要有硬帽
6. **极端日流程**:深度骤降/维护 → 切防守模板
7. **小样本慎重**:<200笔做保守收缩
8. **先截尾再放大**:先证明能控制最大亏损,再考虑放大
---
## 风险提示
- 凯利公式假设你能准确估计胜率和盈亏比
- 现实中有"肥尾",历史数据不代表未来
- 分数凯利比全凯利更安全
- 杠杆交易有强平风险,必须先算安全边际

## ⚡️ 风险提示
- 凯利公式假设你能准确估计胜率和盈亏比
- 现实中有"肥尾",历史数据不代表未来
- 分数凯利比全凯利更安全
- 杠杆交易有强平风险,必须先算安全边际

# 明确告知系统:数据是通过后端 API 提供的
capabilities:

# 🏆 A股/港股量化交易信号
## 运行机制 (Runtime Logic)
本技能通过后端 API (https://a-stock-signals.vercel.app/s) 获取结构化行情数据。
1. **数据请求**:Agent 发起请求
2. **支付挑战**:触发 x402 协议,单次扣费 0.01 USDC
3. **数据解密**:支付完成后,后端返回经过处理的选股结果
## 功能
基于**旱地拔葱**、**N字型态**、**一阳串三阴**三种经典技术形态,实时筛选强势股。
### 旱地拔葱
- 竞价高开 3%+
- 量比 > 2
- 资金净流入前排
### N字型态
- 放量突破前期高点
- 回撤不破突破点
- 再次放量上涨
### 一阳串三阴
- 连续3根阴线下跌
- 一根大阳线突破3根阴线高点
- 成交量配合放大
## 输入
- 市场:A 股 / 港股(默认 A 股)
- 形态类型:旱地拔葱 / N字型态 / 一阳串三阴(可多选)
## 输出
- 推荐股票 3-5 只
- 每只包含:代码 + 名称 + 涨幅 + 资金净流入 + 形态强度 ⭐ + 止损位 + 目标位
## 数据源
- 东方财富 / 同花顺(通过后端API获取)
## 价格
- 每次调用:0.01 USDC
- 支付:x402 协议(Base 链 USDC)
- 收款钱包:0x1a9275EE18488A20C7898C666484081F74Ee10CA
## 适用人群
- 短线交易者
- 技术分析爱好者
- 需要选股参考的投资者
## 风险提示
- 本技能仅供参考,不构成投资建议
- 入场前请做好风险控制
- 过去表现不代表未来收益
