- Cleaned up whitespace and formatting in various files including http.py, language.py, logger.py, safe_exec.py, and SQL migration scripts. - Consolidated import statements and removed unnecessary blank lines. - Updated logging configuration for better clarity. - Enhanced the safe execution code with improved error handling and logging. - Removed commented-out code and unnecessary variables in backfill_zero_trades.py and other scripts. - Added a pyproject.toml for Ruff and Vulture configuration. - Introduced requirements-dev.txt for development dependencies. - Removed commented-out stock entries in init.sql for cleaner migration scripts.

# 多指标组合策略 (均线+RSI+MACD)

# Multi-Indicator Composite Strategy

# ============================================================

#
|
|
# 使用方法:
|
|
# 1. 可配置均线周期、RSI阈值等参数
|
|
# 2. 买入条件: RSI超卖 + MACD金叉 + 成交量放大
|
|
# 3. 卖出条件: RSI超买 或 MACD死叉
