胜率统计(Win Rate)算法详解
📋 目录
算法概述
什么是胜率(Win Rate)?
胜率是指在所有交易中,盈利交易占总交易的百分比,是评估交易策略准确性的关键指标。
指标意义
- Win Rate > 50%: 盈利交易多于亏损交易
- Win Rate = 50%: 盈亏交易数量相等
- Win Rate < 50%: 亏损交易多于盈利交易
为什么需要胜率?
胜率反映了交易策略的成功率,但需要与盈亏比结合分析:
| 胜率 | 盈亏比 | 评估 |
|---|---|---|
| 80% | 1:5 | ❌ 高胜率但盈亏比差 |
| 40% | 5:1 | ✅ 低胜率但盈亏比优秀 |
| 60% | 3:1 | 🏆 理想组合 |
核心概念
1. 胜率(Win Rate)
win_rate = (winning_trades / total_trades) * 100
示例:
- 总交易:100 笔
- 盈利交易:65 笔
- 亏损交易:35 笔
- 胜率: 65%
2. 方向偏好(Bias)
衡量交易者偏向做多还是做空,范围 0-100:
- Bias = 50: 中性,多空平衡
- Bias > 50: 偏多头(Long Bias)
- Bias < 50: 偏空头(Short Bias)
bias = ((long_trades - short_trades) / total_trades * 100 + 100) / 2
示例:
- 总交易:100 笔
- 多头交易:70 笔
- 空头交易:30 笔
- 方向偏好: ((70-30)/100*100+100)/2 = 70(偏多)
3. 交易方向识别
Hyperliquid 交易方向字段(dir)格式:
| 方向字段 | 含义 | 分类 |
|---|---|---|
"Open Long" |
开多仓 | 多头 |
"Close Long" |
平多仓 | 多头 |
"Open Short" |
开空仓 | 空头 |
"Close Short" |
平空仓 | 空头 |
"Short > Long" |
从空翻多 | 多头 |
"Long > Short" |
从多翻空 | 空头 |
计算公式
核心公式
1. 胜率计算
win_rate = (winning_trades / total_pnl_trades) * 100
其中:
- winning_trades: 盈利交易次数(closedPnl > 0)
- total_pnl_trades: 有盈亏的交易总数(排除 closedPnl = 0)
2. 方向偏好计算
bias = ((long_trades - short_trades) / total_trades * 100 + 100) / 2
其中:
- long_trades: 多头交易次数
- short_trades: 空头交易次数
- total_trades: 总交易次数
公式推导
方向偏好推导
假设:
- 总交易数 = 100
- 多头交易 = 70
- 空头交易 = 30
计算步骤:
1. 多空差值 = 70 - 30 = 40
2. 差值占比 = 40 / 100 = 0.4 = 40%
3. 转换到 0-100 范围 = (40 + 100) / 2 = 70
结果:bias = 70(偏多 20%)
边界情况:
- 全部多头:bias = ((100-0)/100*100+100)/2 = 100
- 全部空头:bias = ((0-100)/100*100+100)/2 = 0
- 多空平衡:bias = ((50-50)/100*100+100)/2 = 50
