 Файл из `TIME_SERIES_LSTM_MODEL_PATH` читается ботом автоматически. Даже если LSTM-параметры сохранены, сделка меняется только тогда, когда текущая walk-forward проверка в `crypto_spot_bot/time_series.py` показывает качество лучше baseline.
 
+Автопереобучение запускает тот же train-скрипт, пишет лог в `runtime/lstm_retrain.log` и защищается от параллельных запусков:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File tools\run_lstm_retrain.ps1
+powershell -ExecutionPolicy Bypass -File tools\install_windows_lstm_retrainer.ps1
+```
+
+На Linux/Raspberry Pi можно включить user systemd timer:
+
+```bash
+bash tools/run_lstm_retrain.sh
+bash tools/install_lstm_retrainer_systemd.sh
+```
+
+По умолчанию расписание переобучает каждые 6 часов с `--limit 1000`; Windows-установщик фиксирует пары `BTCUSDT,ETHUSDT,SOLUSDT,XRPUSDT,LTCUSDT`, чтобы первый scheduled run был предсказуемым. Параметры можно переопределить через env: `LSTM_RETRAIN_SYMBOLS`, `LSTM_RETRAIN_LIMIT`, `LSTM_RETRAIN_LOOKBACKS`, `LSTM_RETRAIN_UNITS`, `LSTM_RETRAIN_RIDGES`, `LSTM_RETRAIN_INTERVAL`, `LSTM_RETRAIN_ENV`.
