What this skill does

# OKX CEX Market Data CLI

> **Compliance notice**: This skill provides raw market data only. No strategy, recommendation, or optimization logic is embedded. All indicator outputs are objective numerical values; interpretation and trading decisions remain solely with the user.

Public market data for OKX: prices, order books, candles, funding rates, open interest, instrument info, and technical indicators. All commands are **read-only** and require **no API credentials**.

**Skill routing**
- Market data / indicators → `okx-cex-market` (this skill)
- Account balance / positions → `okx-cex-portfolio`
- Place / cancel orders → `okx-cex-trade`
- Grid / DCA bots → `okx-cex-bot`

## Preflight

Before running any command, follow [`../_shared/preflight.md`](../_shared/preflight.md).
Use `metadata.version` from this file's frontmatter as the reference for Step 2.

## Install

```bash
npm install -g @okx_ai/okx-trade-cli
okx market ticker BTC-USDT   # verify
```

Market data commands return the same public data regardless of demo/live mode — no API credentials required. If the user's profile has `demo=true` set and they want live data context, they can use `--live` to confirm they are in live mode (it has no effect on public market data but clarifies environment). Always inform the user which environment is active (demo or live) when it is relevant to their query. No confirmation needed before running any market command. Add `--json` to any command for raw OKX API v5 response. Add `--env` to wrap the output as `{"env", "profile", "data"}`.

## Operation Flow

### Step 1 — Identify data type and load reference

| User intent | Reference to load |
|---|---|
| Price, candles, order book, recent trades | `{baseDir}/references/price-data-commands.md` |
| Technical indicators (RSI, MACD, EMA, BB, KDJ, SuperTrend, AHR999, Rainbow, etc.) | `{baseDir}/references/indicator-commands.md` |
| Funding rate, mark price, open interest, price limit, index ticker | `{baseDir}/references/derivatives-commands.md` |
| Screen / rank instruments; find top movers, high-OI, high-volume contracts | Use `okx market filter` directly |
| OI history time series for a single instrument | Use `okx market oi-history` directly |
| OI change scanner; find contracts with large OI shifts | Use `okx market oi-change` directly |
| List instruments, discover stock tokens, metals/commodities/forex/bonds, find option instIds | `{baseDir}/references/instrument-commands.md` |
| Multi-step or cross-skill workflows; MCP tool names | `{baseDir}/references/workflows.md` |

### Step 2 — Run commands immediately

All market data commands are read-only — no confirmation needed.

### Step 3 — No writes, no verification needed

All commands in this skill are read-only.

## Edge Cases

- **instId format**: SPOT `BTC-USDT` · SWAP `BTC-USDT-SWAP` · FUTURES `BTC-USDT-250328` · OPTION `BTC-USD-250328-95000-C` · Index `BTC-USD` · Stock token `TSLA-USDT-SWAP` · Metals/Commodities/Forex/Bonds: use `instruments-by-category` to discover valid instIds first
- **OPTION listing**: `instruments --instType OPTION` requires `--uly BTC-USD`; if unknown, run `open-interest --instType OPTION` first to discover active instIds
- **funding-rate / price-limit**: SWAP only · mark-price: SWAP / FUTURES / OPTION only
- **candles `--bar`**: uppercase — `1H` not `1h`; use `--after <ts>` to paginate back into historical data (back to 2021); index-candles supports `--history` for extended history
- **⚠️ Large historical range**: before fetching with `--after`/`--before`, estimate candle count = `time_range_ms / bar_interval_ms`. If estimate > 500, tell the user the estimated count and ask for confirmation before proceeding. This prevents silently filling the context window.
- **indicator `--bar`**: uses `1Dutc` not `1D`, `1Wutc` not `1W` — different from candle bar values
- **`market filter` sortBy values**: `last` `chg24hPct` `marketCapUsd` `volUsd24h` `fundingRate` `oiUsd` `listTime` — default `volUsd24h`
- **`market filter` ctType**: `linear` or `inverse` (SWAP/FUTURES only); omit for SPOT
- **`market filter` quoteCcy**: comma-separated list supported, e.g. `--quoteCcy USDT,USDC`
- **`market filter` SPOT + quoteCcy**: when `--instType SPOT`, the API returns instruments across **all** quote currencies (USDT, USDC, BTC, ETH, etc.) mixed together — this pollutes sort order and bloats results. Always pass `--quoteCcy USDT` by default unless the user explicitly asks for other quote currencies.
- **`market filter` chg24hPct**: value is a percentage number — `--minChg24hPct -5` means -5%, `--maxChg24hPct 10` means 10%
- **`market oi-history` ts**: Unix ms timestamp; returns bars with ts ≤ this value for historical pagination
- **`market oi-history` / `oi-change` bar**: valid values `5m` `15m` `1H` `4H` `1D` — default `1H`. Server accepts case variants (`1h` == `1H`) but prefer canonical casing.
- **`market oi-history` limit**: 1–
