## 🎯 核心算法

### 仓位计算公式

```python
# 各因子权重
信号强度权重 = 0.4  # 40%
风险水平权重 = 0.3  # 30%
市场环境权重 = 0.2  # 20%
资金规模权重 = 0.1  # 10%

# 计算过程
基础仓位 = 信号强度 × 0.4
风险调整 = (1 - 风险水平) × 0.3
环境调整 = 市场环境 × 0.2
资金调整 = 资金充足度 × 0.1

建议仓位 = 基础仓位 + 风险调整 + 环境调整 + 资金调整
最终仓位 = min(建议仓位，80%)  # 最大仓位限制
```

## 📐 仓位计算公式

### 权重分配

| 因子 | 权重 | 说明 |
|------|------|------|
| 信号强度 | 40% | 技术指标 + 形态识别 + 多周期共振 |
| 风险水平 | 30% | 波动率 + 最大回撤 + Beta 系数 |
| 市场环境 | 20% | 大盘趋势 + 行业景气 + 市场情绪 |
| 资金规模 | 10% | 账户总资金 + 可用资金 + 风险承受能力 |

### 计算流程

```python
基础仓位 = 信号强度 × 0.4
风险调整 = (1 - 风险水平) × 0.3
环境调整 = 市场环境 × 0.2
资金调整 = 资金充足度 × 0.1

建议仓位 = 基础仓位 + 风险调整 + 环境调整 + 资金调整
最终仓位 = min(建议仓位，80%)  # 最大仓位限制 80%
```

```

## 快速开始

### 1. Ichimoku Cloud (一目均衡表)

```python
from ichimoku_cloud import (
    calculate_ichimoku,
    get_all_ichimoku_parameters,
    get_ichimoku_summary,
    identify_cloud_breakout,
    identify_tk_cross
)

# 准备数据 (需要包含 high, low, close 列)
df = prepare_your_data()

# 方法 1: 获取 9 个参数
params = get_all_ichimoku_parameters(df)
# 返回：转换线、基准线、先行跨度 A/B、滞后跨度、云团顶部/底部、云团颜色、价格位置

# 方法 2: 获取综合分析报告
summary = get_ichimoku_summary(df)
# 返回：当前价格、总体趋势、操作建议、信号强度等

# 方法 3: 识别云团突破
df_ichimoku = calculate_ichimoku(df)
cloud = identify_cloud_breakout(df_ichimoku)
# 返回：云团颜色、价格位置、突破信号

# 方法 4: 识别 TK 交叉
tk = identify_tk_cross(df_ichimoku)
# 返回：交叉信号 (金叉/死叉)、当前位置
```

**9 个参数说明:**

# 多指标综合分析
ichimoku = get_ichimoku_summary(df)
vwap = get_vwap_summary(df)
supertrend = get_supertrend_summary(df)

# 统计看涨/看跌信号
bullish_count = 0
bearish_count = 0

if ichimoku['overall_trend'] in ['bullish', 'strong_bullish']:
    bullish_count += 1
elif ichimoku['overall_trend'] in ['bearish', 'strong_bearish']:
    bearish_count += 1

if vwap['trend'] == 'bullish':
    bullish_count += 1
elif vwap['trend'] == 'bearish':
    bearish_count += 1

if supertrend['trend'] == 'bullish':
    bullish_count += 1
elif supertrend['trend'] == 'bearish':
    bearish_count += 1

# 综合判断
if bullish_count >= 2:
    recommendation = "买入/持有"
elif bearish_count >= 2:
    recommendation = "卖出/观望"
else:
    recommendation = "观望"
```

## 使用方法

### 基本使用
```python
from ml_predictor import LSTMStockPredictor

# 创建预测器
predictor = LSTMStockPredictor(
    stock_code="000001",  # 股票代码
    time_step=60,         # 时间步长
    lstm_units=50,        # LSTM 神经元数
    lstm_layers=2,        # LSTM 层数
    dropout_rate=0.2,     # Dropout 比例
    forecast_days=5       # 预测天数
)

# 1. 获取数据
df = predictor.fetch_data()

# 2. 特征工程
features = predictor.calculate_features(df)

# 3. 准备序列
X_train, X_test, y_train, y_test = predictor.prepare_sequences(test_size=0.2)

# 4. 构建模型
input_shape = (X_train.shape[1], X_train.shape[2])
predictor.build_model(input_shape)

# 5. 训练模型
predictor.train(X_train, y_train, X_test, y_test, epochs=100, batch_size=32)

# 6. 预测
result = predictor.predict()
print(result)

# 7. 保存模型
predictor.save_model("my_model.h5")
```

### 加载已训练模型
```python
from ml_predictor import LSTMStockPredictor

predictor = LSTMStockPredictor()
predictor.load_model("lstm_stock_predictor.h5")

# 直接预测
result = predictor.predict()
```

### 命令行运行
```bash
cd skills/technical-indicators
python ml_predictor.py
```

## 概述

L3 专家级能力提升 - 多维度市场情绪评分系统

本系统通过整合四大情绪维度（机构、散户、新闻、期权），提供全面的市场情绪分析和交易信号。

## 功能特性

### 1. 情绪维度

| 维度 | 权重 | 指标 |
|------|------|------|
| **机构情绪** | 40% | 北向资金流向、主力资金流向、龙虎榜机构买卖 |
| **散户情绪** | 20% | 融资融券余额变化、散户持仓比例、论坛舆情分析 |
| **新闻情绪** | 20% | 新闻舆情评分、政策解读、行业消息 |
| **期权情绪** | 20% | 期权隐含波动率、Put/Call 比率、期权持仓量 |

### 2. 情绪评分计算

```python
情绪评分 = 机构×0.4 + 散户×0.2 + 新闻×0.2 + 期权×0.2
```

**评分等级:**
- 90-100: 极度乐观
- 70-90: 乐观
- 50-70: 中性
- 30-50: 悲观
- 0-30: 极度悲观

### 3. 输出格式

```json
{
    "score": 75,
    "level": "乐观",
    "factors": {
        "institutional": 80,
        "retail": 70,
        "news": 65,
        "options": 75
    },
    "trend": "上升",
    "signal": "看涨",
    "timestamp": "2026-03-14T22:00:00",
    "weights": {
        "institutional": 0.4,
        "retail": 0.2,
        "news": 0.2,
        "options": 0.2
    }
}
```

## 快速开始

### 基础用法

```python
from market_sentiment import MarketSentimentAnalyzer

# 创建分析器
analyzer = MarketSentimentAnalyzer()

# 执行情绪分析
result = analyzer.analyze(symbol='sh')

# 打印结果
print(f"综合评分：{result['score']}")
print(f"情绪等级：{result['level']}")
print(f"交易信号：{result['signal']}")
```

### 获取 JSON 输出

```python
# 获取 JSON 格式结果
json_output = analyzer.analyze_to_json()
print(json_output)
```

### 回测验证

```python
from market_sentiment import MarketSentimentAnalyzer
from test_market_sentiment import SentimentBacktester

# 创建分析器和回测器
analyzer = MarketSentimentAnalyzer()
backtester = SentimentBacktester(analyzer)

# 运行回测
backtest_result = backtester.run_backtest(days=30)

# 获取统计信息
stats = backtest_result['statistics']
print(f"看涨胜率：{stats['bullish_win_rate']}%")
print(f"看跌胜率：{stats['bearish_win_rate']}%")
```
