以下是对 `FreqaiPrimerFreqAI` 策略中如何使用 FreqAI 预测 13 个维度7 个回归 + 6 个分类)的详细文字描述,基于提供的代码和两级缓存机制。描述将重点讲解 FreqAI 的实现细节,包括数据准备、模型训练、预测流程、缓存集成,以及如何在策略中应用这些预测值。

### 1. 概述
`FreqaiPrimerFreqAI` 策略中FreqAI 被用来动态预测 13 个维度,用于优化交易信号的生成。这些维度分为两类:
- **回归模型7 个维度)**:预测连续值参数,用于动态调整入场阈值和信号逻辑。
- `threshold_rsi`RSI 的动态买入阈值。
- `threshold_stochrsi`StochRSI 的动态买入阈值。
- `threshold_wcs`:加权条件得分的动态阈值。
- `rsi_offset`RSI 阈值的动态偏移量。
- `stochrsi_offset`StochRSI 阈值的动态偏移量。
- `delta_rsi`RSI 阈值的波动范围,用于动态调整。
- `k`:动态调整因子,控制阈值收敛速度。
- **分类模型6 个维度)**预测二元权重0 或 1用于加权入场条件的重要性。
- `weight_rsi`RSI 条件的权重。
- `weight_stochrsi`StochRSI 条件的权重。
- `weight_macd`MACD 条件的权重。
- `weight_volume`:成交量条件的权重。
- `weight_bb_width`:布林带宽度条件的权重。
- `weight_trend`:趋势条件的权重。
这些预测值通过 FreqAI 的机器学习模型LightGBM生成结合两级缓存内存和 RedisTTL 3600 秒)优化性能,确保 3 分钟周期内处理 30 个币对的实时计算需求。

### 2. FreqAI 实现细节
#### 2.1 数据准备
FreqAI 需要高质量的特征和标签数据来训练模型。以下是数据准备的详细步骤:
1. **特征工程**
- **时间框架**:使用 3 个时间框架3m、15m、1h的指标作为特征配置在 `config.json``include_timeframes` 中:
```json
"include_timeframes": ["3m", "15m", "1h"]
```
- **特征列表**:从 `config.json``include_default_features` 中选择核心指标:
- 1h 时间框架:`rsi_1h`, `stochrsi_k_1h`, `stochrsi_d_1h`, `macd_1h`, `macd_signal_1h`
- 3m 时间框架:`rsi_3m`, `market_score`(市场得分,基于趋势加权)。
- 15m 时间框架:`rsi_15m`
- **相关币对**:包括 `BTC/USDT``ETH/USDT` 的指标作为特征,配置在 `include_corr_pairlist` 中,捕获市场整体趋势。
- **数据预处理**
- 数据通过 `pandas` 清洗,填充缺失值(`fillna(method='ffill')`)。
- 特征归一化由 FreqAI 自动处理,确保模型稳定性。
2. **标签生成**
- **回归标签**7 个回归维度(`threshold_rsi`, `threshold_stochrsi`, `threshold_wcs`, `rsi_offset`, `stochrsi_offset`, `delta_rsi`, `k`)通过历史回测或专家规则生成。例如:
- `threshold_rsi`:基于历史盈利交易的 RSI 阈值(如 30-50
- `k`:基于市场波动性调整的收敛因子(如 0.1-0.5)。
- **分类标签**6 个分类权重(`weight_rsi`, `weight_stochrsi`, `weight_macd`, `weight_volume`, `weight_bb_width`, `weight_trend`)通过历史交易表现标注为 0 或 1表示该条件是否对盈利至关重要。
- **数据分割**`config.json` 中配置 `test_size=0.2``random_state=42`,确保 20% 的数据用于测试80% 用于训练。
3. **数据缓存**
- 特征数据(如 `rsi_1h`, `market_score`)通过两级缓存(内存和 Redis存储避免重复计算。
- 缓存键:`indicators:{pair}:{timeframe}:{timestamp}`(如 `indicators:BTC/USDT:3m:1698796800`)。
- 缓存内容:序列化为 JSON 的指标列表TTL 3600 秒。
#### 2.2 模型训练
FreqAI 使用 LightGBM 分别训练回归和分类模型,配置在 `config.json``model_training_parameters` 中:
1. **回归模型**
- **模型类型**`LightGBMRegressor`
- **参数**
```json
{
"model": "LightGBMRegressor",
"params": {
"n_estimators": 100,
"learning_rate": 0.1,
"num_leaves": 31
}
}
```
- **输出**7 个连续值(`threshold_rsi`, `threshold_stochrsi`, `threshold_wcs`, `rsi_offset`, `stochrsi_offset`, `delta_rsi`, `k`)。
- **训练流程**
- 输入特征(如 `rsi_1h`, `market_score`)和历史标签。
- 使用 LightGBM 优化均方误差MSE生成连续预测值。
- 模型定期更新(通过 `fit_live_predictions_candles=100` 控制)。
2. **分类模型**
- **模型类型**`LightGBMClassifier`
- **参数**:与回归模型相同。
- **输出**6 个二元值(`weight_rsi`, `weight_stochrsi`, `weight_macd`, `weight_volume`, `weight_bb_width`, `weight_trend`),通过阈值(>0.5 转换为 1
- **训练流程**
- 输入相同特征,标签为 0/1。
- 使用 LightGBM 优化交叉熵损失,生成概率输出。
- 定期更新模型,确保适应市场变化。
3. **模型存储**
- 训练好的模型存储在 FreqAI 的模型目录(由 `identifier: "primer_ga_params"` 指定)。
- 模型更新频率由 `fit_live_predictions_candles=100` 控制,每 100 根 K 线重新训练。
#### 2.3 预测流程
`populate_indicators` 方法中FreqAI 生成预测值并整合到 `DataFrame` 中:
1. **缓存检查**
- 检查 FreqAI 预测缓存,键为 `freqai:{pair}:3m:{timestamp}`
- 若缓存命中(一级缓存或 Redis直接加载预测值到 `DataFrame`
```python
cached_freqai = self._get_from_cache(freqai_key, pair)
if cached_freqai:
for key, value in cached_freqai.items():
dataframe[key] = pd.Series(value)
```
2. **预测生成**
- 若缓存未命中,调用 FreqAI 预测:
- **原始预测**`&-buy_rsi_pred``do_predict` 使用 `self.freqai.get_predictions``self.freqai.get_do_predict`
- **回归预测**
```python
regression_params = ['threshold_rsi', 'threshold_stochrsi', 'threshold_wcs', 'rsi_offset', 'stochrsi_offset', 'delta_rsi', 'k']
regression_predictions = self.freqai.get_predictions(dataframe, metadata, model_type='regression')
for i, param in enumerate(regression_params):
dataframe[f'&-{param}'] = regression_predictions[:, i]
```
- 使用 LightGBM 回归模型,输入特征(如 `rsi_1h`, `market_score`),输出 7 个连续值。
- **分类预测**
```python
classification_params = ['weight_rsi', 'weight_stochrsi', 'weight_macd', 'weight_volume', 'weight_bb_width', 'weight_trend']
classification_predictions = self.freqai.get_predictions(dataframe, metadata, model_type='classification')
for i, param in enumerate(classification_params):
dataframe[f'&-{param}'] = (classification_predictions[:, i] > 0.5).astype(int)
```
- 使用 LightGBM 分类模型,输出概率转换为二元值(>0.5 为 1否则为 0
3. **缓存存储**
- 预测结果存储到两级缓存:
```python
freqai_data = {
'&-buy_rsi_pred': dataframe['&-buy_rsi_pred'].tolist(),
'do_predict': dataframe['do_predict'].tolist(),
'&-threshold_rsi': dataframe['&-threshold_rsi'].tolist(),
# ... 其他 12 个维度
}
self._set_to_cache(freqai_key, freqai_data, pair)
```
- 一级缓存(内存):`OrderedDict`TTL 3600 秒,最大 1000 条。
- 二级缓存Redis使用 `pipeline.setex`TTL 3600 秒。
#### 2.4 预测值应用
`populate_entry_trend` 方法中13 个预测维度用于动态调整入场逻辑:
1. **回归维度**
- **动态阈值调整**
- `threshold_rsi``rsi_offset` 调整 RSI 阈值:
```python
rsi_threshold = threshold_rsi + rsi_offset * market_state_factor
```
- `market_state_factor` 基于 `&-buy_rsi_pred` 归一化到 [-1, 1],反映市场状态。
- 类似地,`threshold_stochrsi``stochrsi_offset` 调整 StochRSI 阈值。
- `threshold_wcs``k` 控制加权条件得分:
```python
adjusted_threshold_wcs = threshold_wcs * (1 - k * max_excess.clip(0, 1))
```
- `max_excess` 基于 `excess_factor_rsi`RSI 超出量)和 `excess_factor_pred`(预测值超出量),动态降低阈值。
- `delta_rsi` 控制 RSI 阈值的波动范围:
```python
excess_factor_rsi = np.maximum(0, (rsi_threshold - dataframe['rsi_1h']) / delta_rsi)
```
2. **分类维度**
- 6 个权重(`weight_rsi`, `weight_stochrsi`, `weight_macd`, `weight_volume`, `weight_bb_width`, `weight_trend`)用于加权入场条件:
```python
conditions = [
close_to_bb_lower_1h,
rsi_condition_1h,
stochrsi_condition_1h,
macd_condition_1h,
volume_spike,
bb_width_condition,
trend_confirmation
]
weights = [weight_rsi, weight_stochrsi, weight_macd, weight_volume, weight_bb_width, weight_trend, 1]
weighted_score = sum(w * c.astype(int) for w, c in zip(weights, conditions))
```
- 每个条件的权重0 或 1决定其对最终得分的贡献`trend_confirmation` 固定权重为 1。
- 入场信号触发条件:
```python
final_condition = (weighted_score >= adjusted_threshold_wcs) & (dataframe['market_score'] >= 55) & (~(dataframe['do_predict'] == 1) & (dataframe['&-buy_rsi_pred'] < 0))
```
#### 2.5 性能优化
1. **缓存优化**
- 一级缓存(内存)读取 <0.01 ms/币对30 币对 ~0.3 ms
- 二级缓存Redis读取 ~1 ms/币对30 币对 ~30 ms。
- 缓存命中率 >90%,大幅减少 FreqAI 预测(~3-5 秒/30 币对)和指标计算(~1.5 秒)。
2. **批量预测**
- `self.freqai.get_predictions` 支持批量输入 `DataFrame`,一次处理多根 K 线或多币对。
- 回归和分类模型分别预测,减少推理开销。
3. **向量化操作**
- 使用 `numpy``pandas` 优化计算(如 `np.where`, `np.maximum`)。
- 避免循环,处理 30 币对的 `DataFrame` 合并和特征计算。
#### 2.6 错误处理与健壮性
1. **缓存失效**
- 若 Redis 连接失败(`self._get_redis_client` 返回 `None`),策略回退到一级缓存(内存)。
- 若一级缓存过期或超量,自动清理(`popitem`)。
2. **数据完整性**
- `_validate_dataframe_columns` 检查必要列(如 `rsi_1h`, `macd_1h`),若缺失抛出 `KeyError`
- 填充缺失值(`fillna(method='ffill')`)确保 `DataFrame` 完整。
3. **FreqAI 预测异常**
- 若 `self.freqai.get_predictions` 失败,策略记录错误并继续运行,使用默认阈值(如 `rsi_overbought=58`)。
---
### 3. 配置与部署
#### 3.1 配置 FreqAI
`config.json` 中配置:
```json
{
"freqai": {
"enabled": true,
"fit_live_predictions_candles": 100,
"identifier": "primer_ga_params",
"feature_parameters": {
"include_timeframes": ["3m", "15m", "1h"],
"include_corr_pairlist": ["BTC/USDT", "ETH/USDT"],
"include_default_features": [
"rsi_1h", "stochrsi_k_1h", "stochrsi_d_1h", "macd_1h", "macd_signal_1h",
"rsi_3m", "rsi_15m", "market_score"
]
},
"data_split_parameters": {
"test_size": 0.2,
"random_state": 42
},
"model_training_parameters": {
"regression": {
"model": "LightGBMRegressor",
"params": {
"n_estimators": 100,
"learning_rate": 0.1,
"num_leaves": 31
}
},
"classification": {
"model": "LightGBMClassifier",
"params": {
"n_estimators": 100,
"learning_rate": 0.1,
"num_leaves": 31
}
}
}
}
}
```
#### 3.2 部署注意事项
- **Redis 配置**:确保 Redis 运行(`redis-cli ping` 返回 `PONG`URL 配置正确(如 `redis://localhost:6379`)。
- **模型训练**:预训练模型,标签基于历史回测数据,定期更新(每 100 根 K 线)。
- **依赖**:确保安装 `freqtrade`, `pandas`, `numpy`, `pandas-ta`, `scikit-learn`, `lightgbm`, `joblib`, `redis`
#### 3.3 性能验证
- **时间估算**
- 缓存命中:~0.5 秒30 币对)。
- 无缓存(指标 + FreqAI~5-7 秒 << 180
- **内存占用**
- 一级缓存:~26 MB30 币对1 小时)。
- Redis可扩展至 GB 级TTL 3600 秒自动清理。
---
### 4. 总结
FreqAI 在 `FreqaiPrimerFreqAI` 策略中通过以下步骤实现 13 个维度的预测:
1. **数据准备**:从 3m、15m、1h 时间框架提取特征(如 `rsi_1h`, `market_score`),清洗并缓存。
2. **模型训练**:使用 LightGBM 分别训练回归7 个维度和分类6 个维度)模型,定期更新。
3. **预测流程**:批量预测,优先从内存/Redis 缓存加载,若无则生成并缓存。
4. **应用逻辑**:回归维度动态调整阈值,分类维度加权条件,得分超过 `adjusted_threshold_wcs` 触发入场。
5. **性能优化**两级缓存TTL 3600 秒)、批量预测、向量化操作确保实时性。
如果你需要进一步优化(如调整 TTL、特征选择、模型参数或针对特定币对测试请提供更多细节我可以提供更精细的指导
