# Market Evidence Check

## Purpose
Read-only pre-execution evidence for a stated OKX instrument, side, and hypothetical USDT notional. It reads a public OKX order-book snapshot and returns spread, estimated price impact, estimated one-way cost against a declared bps budget, quote age, and displayed-depth checks. Use when the user wants to check market cost/freshness before deciding anything themselves.

GO only means the declared checks passed on that public snapshot. It is not a buy/sell recommendation, trading signal, profit prediction, fill guarantee, or permission to trade.

## Tooling
All commands go through `bin/market_evidence_check.py` (Python standard library only):

```bash
bin/market_evidence_check.py health
bin/market_evidence_check.py check --instrument BTC-USDT --side buy --notional-usdt 1000 --max-cost-bps 30
```
