# OKX CEX Bot Trading

Grid and DCA (Spot & Contract Martingale) bot management on OKX. All bots are **native OKX server-side** — they run on OKX and do not require a local process.

## 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.

## Prerequisites

```bash
npm install -g @okx_ai/okx-trade-cli
okx config init   # select site -> follow browser OAuth flow
```

> **Security**: NEVER accept credentials in chat. Guide users to `okx config init` for setup.

## Credential & Profile Check

**Run before every authenticated command.** The auth method is detected during [preflight](../_shared/preflight.md) Step 2 and remembered for the session.

### Step A — Verify credentials

Run **both** commands — the `apiKey` field from `okx auth status --json` is the auth-binary's internal state and is always `false` regardless of whether `~/.okx/config.toml` has an API-key profile. `okx config show --json` is the only authoritative source for API-key presence.

```bash
okx config show --json      # reveals API-key profiles (TOML config)
okx auth status --json      # reveals OAuth session state (auth-binary state)
```

Apply **in this order** — first match wins:

- `config show --json` has any profile with a non-empty `api_key` field → **API Key mode**. Proceed to Step B.
- No API-key profile **AND** `auth status --json` returns `"status":"logged_in"` → **OAuth mode**. Proceed to Step B.
- No API-key profile **AND** `"status":"pending"` — login is in progress, wait for it to complete.
- No API-key profile **AND** `"status":"not_logged_in"` — stop, load `okx-cex-auth` skill and follow login steps, wait for completion.

### Step B — Confirm trading mode

Resolution:
1. User intent is clear ("real"/"实盘"/"live" → live; "test"/"模拟"/"demo" → demo) → use it, inform user
2. No explicit declaration → check conversation context for previous choice → reuse if found
3. Nothing found → ask: "Live (实盘) or Demo (模拟盘)?" — wait before proceeding

**How to apply the mode depends on auth method (detected in Step A):**

| Auth method | Live (实盘) | Demo (模拟盘) |
|---|---|---|
| **API Key** | `--profile <live-profile>` | `--profile <demo-profile>` |
| **OAuth** | *(no flag needed, live is default)* | `--demo` |

- **API Key users**: run `okx config show --json` to discover available profile names and their `demo` settings.
- **OAuth users**: omit flags for live; add `--demo` for simulated trading.

**After every command**: append `[mode: live]` or `[mode: demo]`

### Handling 401 Errors

**Authentication error** (error contains "401", "Session expired", or "Run `okx auth login` first"):
1. Stop immediately
2. Load `okx-cex-auth` skill and follow re-authentication steps
3. Retry original command

## Skill Routing

| Need | Skill |
|---|---|
| Market data, prices, depth | `okx-cex-market` |
| Account balance, positions, fees | `okx-cex-portfolio` |
| Regular spot/swap/futures orders | `okx-cex-trade` |
| **Grid / DCA bots** | **`okx-cex-bot` (this skill)** |

## Command Index

### Grid Bot

| Command | Type | Description |
|---|---|---|
| `okx bot grid create` | WRITE | Create a grid bot (spot or contract) |
| `okx bot grid amend` | WRITE | Amend price range, grid count, or TP/SL of a running grid bot |
| `okx bot grid stop` | WRITE | Stop a grid bot |
| `okx bot grid orders` | READ | List active or history grid bots |
| `okx bot grid details` | READ | Grid bot details + PnL |
| `okx bot grid sub-orders` | READ | Individual grid fills or pending orders |

### DCA Bot (Spot & Contract)

| Command | Type | Description |
|---|---|---|
| `okx bot dca create` | WRITE | Create a DCA (Martingale) bot (spot or contract) |
| `okx bot dca stop` | WRITE | Stop a DCA bot (spot or contract) |
| `okx bot dca orders` | READ | List active or history DCA bots (default: contract_dca) |
| `okx bot dca details` | READ | DCA bot details + PnL |
| `okx bot dca sub-orders` | READ | DCA cycles and orders within a cycle |

## Operation Flow

### Step 1 — Identify bot type and action

Parse user request → determine module (Grid / DCA) and action (create / stop / list / details).

### Step 2 — Execute

**READ commands** (orders, details, sub-orders): run immediately after profile confirmation.

**WRITE commands** (create, amend, stop): confirm key parameters with user once before executing.

### Step 3 — Verify after writes

- After create → run the corresponding `orders` command to confirm active
- After amend → run `bot grid details` to confirm updated config
- After stop → run `orders --history` to confirm stopped

## Key Rules

- **Never auto-transfer funds.** If balance is insufficient for bot creation, report the shortfall (current available vs required) and ask the user how to proceed: (1) transfer funds manually, (2) reduce size, or (3) cancel.
- **`algoId`** is the bot's algo order ID (from create or list output). It is NOT a normal `ordId`. Never fabricate — always obtain from a prior command.
- **`algoOrdType`** for grid must match the bot's actual type. Always use the value from `bot grid orders` — do not infer from user description alone. Mismatch causes error `50016`.
- When operating on existing bots, **always list first** to get correct IDs, unless the user provides them explicitly.
- **TP/SL constraints**: `tpTriggerPx`/`tpRatio` and `slTriggerPx`/`slRatio` are mutually exclusive pairs.

### Grid Bot — Stop

```bash
okx bot grid stop --algoId <id> --algoOrdType <type> --instId <id> \

> **`--algoId`** and **`--algoOrdType`** must come from `bot grid orders` output. The `algoOrdType` must match the bot's actual type — do not guess.

**Workflow:**
1. Run `bot grid details --algoId <id> --algoOrdType <type>` and check the `state` field.
2. If `state=running`: call stop with `--stopType 1` (default, clean exit) or `--stopType 2` (keep assets).
3. If `state=no_close_position` (user previously stopped with stopType=2): call stop again with `--stopType 1` to close the remaining open position.

| `--stopType` | Spot grid | Contract grid |
|---|---|---|
| `1` (default) | Sells all base assets back to quote | Market-closes all open positions |
| `2` | Keeps base assets as-is | Cancels grid orders, leaves position open |

## Edge Cases

### Grid Bot

- **Price out of range**: `--minPx` must be < current price < `--maxPx`; check with `okx-cex-market` first
- **Insufficient balance**: check `okx-cex-portfolio` → `account balance` before creating. If insufficient, **do NOT auto-transfer** — report the shortfall and ask the user for instructions
- **Contract grid direction**: `long` (buys more at lower prices), `short` (sells at higher), `neutral` (both). Direction is required for contract grid
- **Contract grid basePos**: defaults to `true` — long/short grids automatically open a base position at creation. Neutral direction ignores this. Pass `--no-basePos` to disable
- **Contract grid --sz**: investment margin in USDT (USDT-M) or coin (coin-M), not number of contracts
- **Coin-margined grids**: use inverse instruments (e.g., `BTC-USD-SWAP`). Margin unit is the base coin (BTC), not USDT
- **Stop type**: `stopType 1` sells/closes all (default); `stopType 2` keeps assets as-is (spot grid) or leaves position open for manual close (contract grid)
- **TP/SL**: `tpTriggerPx`/`tpRatio` and `slTriggerPx`/`slRatio` are mutually exclusive pairs. Ratio-based TP/SL is contract grid only
- **Amend — at least one mode required**: must provide either price-range params (`--maxPx`+`--minPx`+`--gridNum`) or TP/SL params; providing neither returns a validation error
- **Amend — combined mode**: price-range and TP/SL can be combined in one call (two sequential API requests internally)
- **Amend — clear TP/SL**: pass `--tpTriggerPx=-1` or `--slTriggerPx=-1` (use `=` syntax for negative values, not `--flag -1`)
- **Amend — contract grid topUpAmt**: if new range requires more margin, provide `--topUpAmt`; omit to auto-use the minimum required
- **Amend — spot grid topUpAmt**: not supported; omit `--topUpAmt` for spot grids
- **Already stopped bot**: stop returns error — check `bot grid orders --history` first to confirm state
- **Insufficient margin (51340)**: extract required minimum from error, check balance via `okx-cex-portfolio`, report shortfall to user — do NOT auto-transfer
- **Demo mode**: `okx --demo bot grid create ...` (OAuth) or `okx --profile <demo-profile> bot grid create ...` (API Key) — safe for testing, no real funds
- **algoClOrdId duplicate**: if the same `algoClOrdId` already exists, the API returns error code `51065`

### DCA Bot

- **Spot DCA direction**: must always be `long`. If user says "short spot DCA", explain that spot DCA only supports long direction
- **Spot DCA stopType**: always ask user whether to sell all tokens (`1`) or keep them (`2`) when stopping
- **Contract DCA lever**: required. If missing, the tool returns a validation error
- **pxStepsMult**: `1.0` = equal spacing; `>1.0` = widen gaps between successive safety orders
- **volMult**: `1.0` = equal sizes; `>1.0` = increase per safety order (Martingale scaling)
- **triggerStrategy**: `instant` starts immediately; `price` waits for trigger price (contract_dca only); `rsi` waits for RSI condition (both spot_dca and contract_dca)
- **Already stopped bot**: stop returns error — check `bot dca orders --history` first
- **Demo mode**: `okx --demo bot dca create ...` (OAuth) or `okx --profile <demo-profile> bot dca create ...` (API Key) — safe testing, no real funds
- **INVALID_PRICE_STEPS_MULTIPLIER error**: adjust `slPct`. Recalculate MPD = Σ(pxSteps × pxStepsMult^i) for i = 0..maxSafetyOrds−1, then set `slPct` > MPD
- **algoClOrdId duplicate**: error code `51065`

## Communication Guidelines

- **Grid/DCA**: use "bot" not "strategy" (e.g., "grid bot", "DCA bot")
- **DCA**: always say "DCA" or "Martingale" — DCA supports both Spot DCA and Contract DCA
- **Chinese**: Grid = "网格", Spot DCA = "现货马丁", Contract DCA = "合约马丁"
- Use natural language for parameters — "What price range?" not "Enter minPx and maxPx"
- If the user already provides values, map directly — don't re-ask

### Parameter Display Names

> `{base}` and `{quote}`: extract from `instId` by splitting on `-`. E.g., `BTC-USDT-SWAP` → base=BTC, quote=USDT.

> **`slPct` stop-loss logic:**
> - Long: stop-loss price = initial fill price × (1 − slPct)
> - Short: stop-loss price = initial fill price × (1 + slPct)
> When triggered and position fully closed, the bot ends.

## Global Notes

- All bots run on OKX servers — stopping the CLI does not affect them
- Auth method and trading mode are determined in "Credential & Profile Check"; see that section for parameter rules
- `--json` returns the raw OKX API v5 response by default. Add `--env` to wrap the output as `{"env": "<live|demo>", "profile": "<name>", "data": <response>}`
- Rate limit: 20 requests per 2 seconds per UID
- Grid `--gridNum` range: 2–100
