# FinRL 强化环境 (finrl-meta-envs)

> 提供多市场金融强化学习环境，支持PPO/DQN等DRL算法回测、Markowitz组合优化与实时模拟交易，适配Alpaca等券商接口。

## Pipeline

`data_collection -> data_storage -> factor_computation -> target_selection -> trading_execution -> visualization`

## Top Use Cases (9 total)

### Automated Paper Trading with PPO Agent (`UC-101`)
Execute simulated paper trades in real-time using a trained PPO reinforcement learning agent connected to Alpaca brokerage API, enabling risk-free str
**Triggers**: paper trading, PPO agent, Alpaca

### Alpaca Paper Trading Demo with PPO (`UC-104`)
Demonstrate live paper trading execution using a PPO neural network agent connected to Alpaca's paper trading API, enabling real-time trade simulation
**Triggers**: paper trading, Alpaca demo, PPO

### Markowitz Mean-Variance Portfolio Optimization (`UC-102`)
Optimize portfolio allocation across multiple assets using Markowitz mean-variance optimization to maximize risk-adjusted returns, balancing expected
**Triggers**: portfolio optimization, Markowitz, mean-variance

For all **9** use cases, see [references/USE_CASES.md](references/USE_CASES.md).

**Execute trigger**: `When user intent matches intent_router.uc_entries[].positive_terms AND user uses action verb (run/execute/跑/执行/backtest/fetch/collect)`

## What I'll Ask You

- Target market: A-share (default), HK, or crypto? (US stocks in ZVT are half-baked — stockus_nasdaq_AAPL exists but coverage is thin)
- Data source / provider: eastmoney (free, no account), joinquant (account+paid), baostock (free, good history), akshare, or qmt (broker)?
- Strategy type: MACD golden-cross, MA crossover, volume breakout, fundamental screen, or custom factor?
- Time range: start_timestamp and end_timestamp for backtest period
- Target entity IDs: specific stocks (stock_sh_600000) or index components (SZ1000)?

## Semantic Locks (Fatal)

| ID | Rule | On Violation |
|---|---|---|
| `SL-01` | Execute sell orders before buy orders in every trading cycle | halt |
| `SL-02` | Trading signals MUST use next-bar execution (no look-ahead) | halt |
| `SL-03` | Entity IDs MUST follow format entity_type_exchange_code | halt |
| `SL-04` | DataFrame index MUST be MultiIndex (entity_id, timestamp) | halt |
| `SL-05` | TradingSignal MUST have EXACTLY ONE of: position_pct, order_money, order_amount | halt |
| `SL-06` | filter_result column semantics: True=BUY, False=SELL, None/NaN=NO ACTION | halt |
| `SL-07` | Transformer MUST run BEFORE Accumulator in factor pipeline | halt |
| `SL-08` | MACD parameters locked: fast=12, slow=26, signal=9 | halt |

## Top Anti-Patterns (25 total)

- **`AP-ZVT-183`**: 除权因子为 inf/NaN 时直接参与乘法导致复权静默失败
- **`AP-ZVT-179`**: 第三方数据接口超限后异常被吞噬，数据静默缺失
- **`AP-ZVT-183B`**: HFQ（后复权）与 QFQ（前复权）K 线表使用错误导致因子计算漂移
