# 🎯 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% |

## 风险提示

- EV是基于历史数据的期望，不代表未来
- 实际执行需考虑滑点、费率、资金费等摩擦成本
- 慎用小样本数据，容易产生偏差

# Kelly Formula 仓位管理器

**标签**: crypto, trading, kelly-formula, position-sizing, risk-management
**作者**: Rich (@samhuang2025)

---

## 简介

基于凯利公式的加密货币仓位计算工具，帮助交易者用数学纪律替代情绪化决策。

**核心功能**：
- ✅ 凯利公式仓位计算
- ✅ 分数凯利建议（½ / ¼）
- ✅ 多策略仓位分配
- ✅ 杠杆安全边际计算

---

## 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

## 💰 价格

**0.01 USDC** - 通过x402协议支付

```bash
# 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-crypto"
  }'
```

---

## 📖 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

---

## 🚀 快速开始

### 安装

```bash
git clone https://github.com/jinboh68-prog/kelly-formula-crypto.git
cd kelly-formula-crypto
pip install -r requirements.txt
```

### 使用

```bash
# 基本用法
python scripts/kelly_calculator.py -p 0.55 -w 5 -l 3

# 使用½凯利
python scripts/kelly_calculator.py -p 0.60 -w 5 -l 3 -f 0.5

# 杠杆检查
python scripts/kelly_calculator.py -p 0.55 -w 5 -l 3 --leverage 5 --liquidation 10 --stop-loss 3

# JSON输出
python scripts/kelly_calculator.py -p 0.70 -w 2 -l 1 --json
```

### 示例输出

```
📊 Kelly Formula 计算结果
========================================
胜率: 55% | 盈亏比: 1.67

🧮 仓位建议:
  全凯利: 28.0%
  ½凯利:  14.0%
  ¼凯利:  7.0%

✅ 推荐仓位: 14.0%
```

## 📊 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% |

## ⚠️ 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

---

## 🔧 API

```python
from kelly_calculator import kelly_position, calculate_trade

# 基础计算
position = kelly_position(p=0.55, b=1.67, fraction=0.5)
print(f"建议仓位: {position*100}%")

# 完整计算
result = calculate_trade(
    p=0.60,
    win_pct=5,
    loss_pct=3,
    fraction=0.5,
    leverage=3,
    liquidation_pct=20,
    stop_loss_pct=5
)
print(result)
```

---

## 📚 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%**

---

## ⚡️ 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

# 🚀 A股强势股捕捉器

## 运行机制 (Runtime Logic)

本技能通过后端 API (https://a-stock-signals.vercel.app/n) 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 A 股 N字型态筛选结果

## 功能

基于 **N字型态** 经典技术形态，实时筛选强势股。

### N字型态特征

**第一笔（上涨）**：
- 放量突破前期高点
- 成交量明显放大

**第二笔（回撤）**：
- 回撤不破突破点
- 缩量回调（量能萎缩）

**第三笔（再涨）**：
- 再次放量上涨
- 突破第一笔高点

## 输入

- 市场：A股（默认）
- 形态类型：N字型态

## 输出

- 推荐股票 3-5 只
- 每只包含：
  - 代码 + 名称
  - 所处板块
  - N字型态阶段（突破/回撤/再次启动）
  - 强势度 ⭐⭐⭐/⭐⭐/⭐
  - 放量情况
  - 止损位 + 目标位
  - 买入理由

## 数据源

- 东方财富 / 同花顺（通过后端API获取）
- 备用：新浪财经 / 腾讯财经

## 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（建议-5%止损）
- 过去表现不代表未来收益
