> I help you build quant strategies on A-share with ZVT — from data fetch to backtest, one flow. Just tell me what you want; I'll write the code, you don't have to dig docs. (Heads up: ZVT natively supports A-share, HK, and crypto. US stocks — stockus_nasdaq_AAPL — are half-baked; don't bother for serious work.)

## What I Can Do

- **tagline**: I help you build quant strategies on A-share with ZVT — from data fetch to backtest, one flow. Just tell me what you want; I'll write the code, you don't have to dig docs. (Heads up: ZVT natively supports A-share, HK, and crypto. US stocks — stockus_nasdaq_AAPL — are half-baked; don't bother for serious work.)
- **use_cases**: ['Bond Step-Up Rate', 'Adjustable Rate Mortgage Pool', 'Basic ABS Deal Model', 'A-share MACD daily golden-cross backtest with hfq price adjustment from eastmoney', 'End-to-end ZVT pipeline: FinanceRecorder + GoodCompanyFactor + StockTrader', 'Multi-factor strategy with TargetSelector (AND mode) combining MACD + volume breakout', 'Index composition data collection (SZ1000, SZ2000) with EM recorder']

## What I 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)?

## Preconditions (4)

- **`PC-01`**: `python3 -c 'import zvt; print(zvt.__version__)'` → on_fail: Run: python3 -m pip install zvt then re-run: python3 -m zvt.init_dirs to initialize data directories
- **`PC-02`**: `python3 -c "from zvt.api.kdata import get_kdata; df = get_kdata(entity_ids=['stock_sh_600000'], limit=1); assert df is not None and len(df) > 0, 'No kdata found'"` → on_fail: Run recorder first: python3 -m zvt.recorders.em.em_stock_kdata_recorder --entity_ids stock_sh_600000 (replace with your target entity IDs)
- **`PC-03`**: `python3 -c "import os; from pathlib import Path; zvt_home = Path(os.environ.get('ZVT_HOME', Path.home() / '.zvt')); assert zvt_home.exists(), f'ZVT home not found: {zvt_home}'"` → on_fail: Run: python3 -m zvt.init_dirs
- **`PC-04`**: `python3 -c "import os, tempfile; from pathlib import Path; zvt_home = Path(os.environ.get('ZVT_HOME', Path.home() / '.zvt')); test_f = zvt_home / '.write_test'; test_f.touch(); test_f.unlink()"` → on_fail: Check directory permissions: chmod u+w ~/.zvt or set ZVT_HOME environment variable to a writable location
