|
||||
### 1. 概述
|
||||
|
||||
在 `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 Redis,TTL 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` 的 `include_timeframes` 中:
|
||||
```json
|
||||
"include_timeframes": ["3m", "15m", "1h"]
|
||||
```
|
||||
- **特征列表**:从 `config.json` 的 `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` 和 `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` 和 `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` 的 `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
|
||||
|
||||
在 `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` 和 `do_predict` 使用 `self.freqai.get_predictions` 和 `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
|
||||
|
||||
在 `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` 和 `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` 和 `stochrsi_offset` 调整 StochRSI 阈值。
|
||||
- `threshold_wcs` 和 `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` 和 `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
|
||||
在 `config.json` 中配置:
|
||||
```json
|
||||
{
|
||||
"freqai": {
|
||||
"enabled": true,
|
||||
"fit_live_predictions_candles": 100,
|
||||

|
||||
"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 秒。
|
||||
- **内存占用**:
|
||||
- 一级缓存:~26 MB(30 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!
