Open Broker - Hyperliquid Trading CLI

Execute trading operations on Hyperliquid DEX with builder fee support.

Installation

npm install -g openbroker

Quick Start

# 1. Setup (generates wallet, creates config, approves builder fee)
openbroker setup

# 2. Fund your wallet with USDC on Arbitrum, then deposit at https://app.hyperliquid.xyz/

# 3. Start trading
openbroker account
openbroker buy --coin ETH --size 0.1

Important: Finding Assets Before Trading

Always search before trading an unfamiliar asset. Hyperliquid has main perps (ETH, BTC, SOL...), HIP-3 perps (xyz:CL, xyz:GOLD, km:USOIL...), and spot markets. Use search to discover the correct ticker:

openbroker search --query GOLD              # Find all GOLD markets across all providers
openbroker search --query oil               # Find oil-related assets (CL, BRENTOIL, USOIL...)
openbroker search --query BTC --type perp   # BTC perps only
openbroker search --query NATGAS --type hip3  # HIP-3 only

Or with the ob_search plugin tool: { "query": "gold" } or { "query": "oil", "type": "hip3" }

HIP-3 assets use dex:COIN format — e.g., xyz:CL not just CL. If you get an error like "No market data found", search for the asset to find the correct prefixed ticker. Common HIP-3 dexes: xyz, flx, km, hyna, vntl, cash.

Troubleshooting: CLI Fallback

If an ob_* plugin tool returns unexpected errors, empty results, or crashes, fall back to the equivalent CLI command via Bash. The CLI and plugin tools share the same core code, but the CLI has more mature error handling and output.

Plugin Tool	CLI Equivalent
ob_account	openbroker account --json
ob_positions	openbroker positions --json
ob_funding	openbroker funding --json --include-hip3
ob_markets	openbroker markets --json --include-hip3
ob_search	openbroker search --query <QUERY>
ob_buy	openbroker buy --coin <COIN> --size <SIZE>
ob_sell	openbroker sell --coin <COIN> --size <SIZE>
ob_limit	openbroker limit --coin <COIN> --side <SIDE> --size <SIZE> --price <PRICE>
ob_tpsl	openbroker tpsl --coin <COIN> --tp <PRICE> --sl <PRICE>
ob_cancel	openbroker cancel --all or --coin <COIN>
ob_fills	openbroker fills --json
ob_orders	openbroker orders --json
ob_funding_scan	openbroker funding-scan --json
ob_candles	openbroker candles --coin <COIN> --json
ob_auto_run	openbroker auto run <script> [--dry]
ob_auto_stop	(stop via SIGINT when using CLI)
ob_auto_list	openbroker auto list

When to use CLI fallback:

• Plugin tool returns null, empty data, or throws an error
• You need data the plugin tool doesn't expose (e.g., --verbose debug output)
• Long-running operations (strategies, TWAP) — the CLI handles timeouts and progress better

Add --dry to any trading CLI command to preview without executing. Add --json to info commands for structured output.

Command Reference

Setup

openbroker setup              # One-command setup (wallet + config + builder approval)
openbroker approve-builder --check  # Check builder fee status (for troubleshooting)

The setup command offers three modes:

1. Generate fresh wallet (recommended for agents) — creates a dedicated trading wallet with builder fee auto-approved. No browser steps needed — just fund with USDC and start trading.
2. Import existing key — use a private key you already have
3. Generate API wallet — creates a restricted wallet that can trade but cannot withdraw. Requires browser approval from a master wallet.

For options 1 and 2, setup saves config and approves the builder fee automatically. For option 3 (API wallet), see the API Wallet Setup section below.

Fresh Wallet Setup (Recommended for Agents)

The simplest setup for agents. A fresh wallet is generated, the builder fee is auto-approved, and the agent is ready to trade immediately after funding.

Flow:

1. Run openbroker setup and choose option 1 ("Generate a fresh wallet")
2. The CLI generates a wallet, saves the config, and approves the builder fee automatically
3. Fund the wallet with USDC on Arbitrum, then deposit at https://app.hyperliquid.xyz/
4. Start trading

API Wallet Setup (Alternative)

API wallets can place trades on behalf of a master account but cannot withdraw funds. Use this if you prefer to keep funds in your existing wallet and only delegate trading access.

Flow:

1. Run openbroker setup and choose option 3 ("Generate API wallet")
2. The CLI generates a keypair and prints an approval URL (e.g. https://openbroker.dev/approve?agent=0xABC...)
3. The agent owner opens the URL in a browser and connects their master wallet (MetaMask etc.)
4. The master wallet signs two transactions: ApproveAgent (authorizes the API wallet) and ApproveBuilderFee (approves the 1 bps fee)
5. The CLI detects the approval automatically and saves the config

After setup, the config will contain:

HYPERLIQUID_PRIVATE_KEY=0x...        # API wallet private key
HYPERLIQUID_ACCOUNT_ADDRESS=0x...    # Master account address
HYPERLIQUID_NETWORK=mainnet

Important for agents: When using an API wallet, pass the approval URL to the agent owner (the human who controls the master wallet). The owner must approve in a browser before the agent can trade. The CLI waits up to 10 minutes for the approval. If it times out, re-run openbroker setup.

Order Types

Limit Orders vs Trigger Orders

Limit Orders (openbroker limit):

• Execute immediately if price is met
• Rest on the order book until filled or cancelled
• A limit sell BELOW current price fills immediately (taker)
• NOT suitable for stop losses

Trigger Orders (openbroker trigger, openbroker tpsl):

• Stay dormant until trigger price is reached
• Only activate when price hits the trigger level
• Proper way to set stop losses and take profits
• Won't fill prematurely

When to Use Each

Scenario	Command
Buy at specific price below market	openbroker limit
Sell at specific price above market	openbroker limit
Stop loss (exit if price drops)	openbroker trigger --type sl
Take profit (exit at target)	openbroker trigger --type tp
Add TP/SL to existing position	openbroker tpsl

Common Arguments

All commands support --dry for dry run (preview without executing).

Argument	Description
--coin	Asset symbol (ETH, BTC, SOL, HYPE, etc.)
--side	Order direction: buy or sell
--size	Order size in base asset
--price	Limit price
--dry	Preview without executing
--help	Show command help

Order Arguments

Argument	Description
--trigger	Trigger price (for trigger orders)
--type	Trigger type: tp or sl
--slippage	Slippage tolerance in bps (for market orders)
--tif	Time in force: GTC, IOC, ALO
--reduce	Reduce-only order

TP/SL Price Formats

Format	Example	Description
Absolute	--tp 40	Price of $40
Percentage up	--tp +10%	10% above entry
Percentage down	--sl -5%	5% below entry
Entry price	--sl entry	Breakeven stop

Configuration

Config is loaded from (in priority order):

1. Environment variables
2. .env in current directory
3. ~/.openbroker/.env (global config)

Run openbroker setup to create the global config interactively.

Variable	Required	Description
HYPERLIQUID_PRIVATE_KEY	Yes	Wallet private key (0x...)
HYPERLIQUID_NETWORK	No	mainnet (default) or testnet
HYPERLIQUID_ACCOUNT_ADDRESS	No	Master account address (required for API wallets)

The builder fee (1 bps / 0.01%) is hardcoded and not configurable.

OpenClaw Plugin (Optional)

This skill works standalone via Bash — every command above runs through the openbroker CLI. For enhanced features, the same openbroker npm package also ships as an OpenClaw plugin that you can enable alongside this skill.

What the plugin adds

• Structured agent tools (ob_account, ob_buy, ob_limit, etc.) — typed tool calls with proper input schemas instead of Bash strings. The agent gets structured JSON responses.
• Background position watcher — polls your Hyperliquid account every 30s and sends webhook alerts when positions open/close, PnL moves significantly, or margin usage gets dangerous.
• Automation tools (ob_auto_run, ob_auto_stop, ob_auto_list) — start, stop, and manage custom trading automations from within the agent.
• CLI commands — openclaw ob status and openclaw ob watch for inspecting the watcher.

Enable the plugin

The plugin is bundled in the same openbroker npm package. To enable it in your OpenClaw config:

plugins:
  entries:
    openbroker:
      enabled: true
      config:
        hooksToken: "your-hooks-secret"   # Required for watcher alerts
        watcher:
          enabled: true
          pollIntervalMs: 30000
          pnlChangeThresholdPct: 5
          marginUsageWarningPct: 80

The plugin reads wallet credentials from ~/.openbroker/.env (set up by openbroker setup), so you don't need to duplicate privateKey in the plugin config unless you want to override.

Webhook setup for watcher alerts

For position alerts to reach the agent, enable hooks in your gateway config:

hooks:
  enabled: true
  token: "your-hooks-secret"   # Must match hooksToken above

Without hooks, the watcher still runs and tracks state (accessible via ob_watcher_status), but it can't wake the agent.

Using with or without the plugin

• Skill only (no plugin): Use Bash commands (openbroker buy --coin ETH --size 0.1). No background monitoring.
• Skill + plugin: The agent prefers the ob_* tools when available (structured data), falls back to Bash for commands not covered by tools (strategies, scale). Background watcher sends alerts automatically.

Trading Automations

Automations let you write custom event-driven trading logic as TypeScript scripts. Instead of using the rigid built-in strategies, write exactly the logic you need and OpenBroker handles the polling, event detection, and SDK access.

How Automations Work

An automation is a .ts file that exports a default function. The function receives an AutomationAPI with the full Hyperliquid client, typed event subscriptions, persistent state, and a logger. The runtime polls Hyperliquid every 10s (configurable) and dispatches events when changes are detected.

Writing an Automation

Create a .ts file in ~/.openbroker/automations/ (or any path):

// ~/.openbroker/automations/funding-scalp.ts
export default function(api) {
  const COIN = 'ETH';

  api.on('funding_update', async ({ coin, annualized }) => {
    if (coin !== COIN) return;

    if (annualized > 0.5 && !api.state.get('isShort')) {
      api.log.info('High positive funding — going short');
      await api.client.marketOrder(COIN, false, 0.1);
      api.state.set('isShort', true);
    } else if (annualized < -0.1 && api.state.get('isShort')) {
      api.log.info('Funding normalized — closing short');
      await api.client.marketOrder(COIN, true, 0.1);
      api.state.set('isShort', false);
    }
  });

  api.onStop(async () => {
    if (api.state.get('isShort')) {
      api.log.warn('Closing short on shutdown');
      await api.client.marketOrder('ETH', true, 0.1);
      api.state.set('isShort', false);
    }
  });
}

Events

Event	Payload	When
tick	{ timestamp, pollCount }	Every poll cycle (default: 10s)
price_change	{ coin, oldPrice, newPrice, changePct }	Mid price moved > 0.01% between polls
funding_update	{ coin, fundingRate, annualized, premium }	Every poll for all assets
position_opened	{ coin, side, size, entryPrice }	New position detected
position_closed	{ coin, previousSize, entryPrice }	Position no longer present
position_changed	{ coin, oldSize, newSize, entryPrice }	Position size changed
pnl_threshold	{ coin, unrealizedPnl, changePct, positionValue }	PnL moved > 5% of position value
margin_warning	{ marginUsedPct, equity, marginUsed }	Margin usage > 80%

Event Details — Choosing the Right Event

tick — The universal heartbeat

Fires every single poll cycle (default: 10s) regardless of market conditions. Use this when you need to check something on every poll — absolute price thresholds, custom conditions, periodic account checks. This is the most reliable event because it always fires.

Payload: { timestamp: number, pollCount: number }

When to use:

• Checking if a price is above/below an absolute threshold (e.g. "alert me when ETH < $3000")
• Custom conditions that don't fit other events (e.g. "if I have no positions and funding is high, enter")
• Periodic tasks that need to run every poll (though api.every() is better for longer intervals)

Example — absolute price alert:

api.on('tick', async () => {
  const mids = await api.client.getAllMids();
  const price = parseFloat(mids['HYPE']);
  if (price < 38 && !api.state.get('alerted')) {
    api.state.set('alerted', true);
    await api.publish(`HYPE dropped below $38 — now at $${price.toFixed(3)}`);
  }
});

Note: tick does not include price data in its payload — you must fetch it yourself via api.client.getAllMids(). This is because tick fires before any other event processing. If you only care about price movements, use price_change instead.

price_change — Relative price movements

Fires when a coin's mid price moves ≥ 0.01% compared to the previous poll. This filters out rounding noise while catching virtually any real price movement. The comparison is between consecutive polls (not from a fixed baseline), so it detects incremental changes.

Payload: { coin: string, oldPrice: number, newPrice: number, changePct: number }

When to use:

• Reacting to price movements (breakouts, momentum, mean reversion)
• Monitoring specific coins for volatility
• Building price-triggered entry/exit logic

When NOT to use:

• Checking if price is above/below a fixed threshold — use tick instead, because price_change only fires on relative movement between polls. During slow drifts (e.g. price slowly declining $0.001/s), the change between any two 10s polls may be < 0.01%, so the event won't fire even though the price has crossed your threshold.

Example — momentum detector:

api.on('price_change', async ({ coin, changePct, newPrice }) => {
  if (coin !== 'ETH') return;
  if (changePct > 0.5) {
    api.log.info(`ETH surging +${changePct.toFixed(2)}% — price $${newPrice}`);
    // Enter long on strong upward momentum
  }
});

funding_update — Funding rate data

Fires every poll for every asset that has funding rate data. This is high-frequency — if there are 150 perp assets, this fires 150 times per poll. Filter by coin in your handler.

Payload: { coin: string, fundingRate: number, annualized: number, premium: number }

• fundingRate — the raw hourly funding rate (e.g. 0.0001 = 0.01%/hr)
• annualized — annualized rate (fundingRate × 8760 × 100, as a percentage)
• premium — the premium component

When to use:

• Funding rate arbitrage strategies
• Monitoring for extreme funding (entry/exit signals)
• Scanning for highest/lowest funding across all assets

Example — funding scalp:

api.on('funding_update', async ({ coin, annualized }) => {
  if (coin !== 'ETH') return;
  if (annualized > 50 && !api.state.get('isShort')) {
    api.log.info(`ETH funding at ${annualized.toFixed(1)}% annualized — shorting`);
    await api.client.marketOrder('ETH', false, 0.1);
    api.state.set('isShort', true);
  }
});

position_opened — New position detected

Fires when a position appears that wasn't present in the previous poll. Useful for tracking entries made by other systems or confirming your own orders filled.

Payload: { coin: string, side: 'long' | 'short', size: number, entryPrice: number }

When to use:

• Setting TP/SL on new positions automatically
• Logging/alerting when positions are opened (by you or another system)
• Starting position-specific monitoring

Example — auto TP/SL on new positions:

api.on('position_opened', async ({ coin, side, size, entryPrice }) => {
  const tpPrice = side === 'long' ? entryPrice * 1.05 : entryPrice * 0.95;
  const slPrice = side === 'long' ? entryPrice * 0.97 : entryPrice * 1.03;
  await api.client.takeProfit(coin, side !== 'long', size, tpPrice);
  await api.client.stopLoss(coin, side !== 'long', size, slPrice);
  api.log.info(`Set TP at ${tpPrice} / SL at ${slPrice} for ${coin}`);
});

position_closed — Position gone

Fires when a position that existed in the previous poll is no longer present. The position was either closed by you, liquidated, or filled by TP/SL.

Payload: { coin: string, previousSize: number, entryPrice: number }

When to use:

• Logging/alerting when positions close
• Cleaning up related orders or state
• Re-entry logic after a position closes

Example:

api.on('position_closed', async ({ coin, previousSize, entryPrice }) => {
  api.log.info(`${coin} position closed (was ${previousSize} @ ${entryPrice})`);
  api.state.delete(`${coin}_tp`);
  await api.publish(`Position closed: ${coin} (entry: $${entryPrice})`);
});

position_changed — Size or direction changed

Fires when an existing position's size changes (partial close, add to position, or flip direction). Does NOT fire when a new position opens or an existing one fully closes — use position_opened and position_closed for those.

Payload: { coin: string, oldSize: number, newSize: number, entryPrice: number }

• oldSize/newSize are signed: positive = long, negative = short

When to use:

• Detecting partial closes or position scaling
• Adjusting TP/SL when position size changes
• Tracking DCA entries

Example:

api.on('position_changed', async ({ coin, oldSize, newSize }) => {
  if (Math.abs(newSize) > Math.abs(oldSize)) {
    api.log.info(`${coin} position increased: ${oldSize} → ${newSize}`);
  } else {
    api.log.info(`${coin} position reduced: ${oldSize} → ${newSize}`);

pnl_threshold — Significant PnL movement

Fires when unrealized PnL changes by ≥ 5% of position value between consecutive polls. This is a large move detector — useful for risk management alerts rather than routine monitoring.

Payload: { coin: string, unrealizedPnl: number, changePct: number, positionValue: number }

• changePct — the PnL change as a percentage of total position value (not % of PnL itself)

When to use:

• Risk alerts for large PnL swings
• Auto-close or reduce positions on sudden adverse moves
• Escalating alerts to the user via api.publish()

Example:

api.on('pnl_threshold', async ({ coin, unrealizedPnl, changePct }) => {
  if (unrealizedPnl < 0) {
    await api.publish(
      `⚠️ ${coin} PnL dropped sharply: $${unrealizedPnl.toFixed(2)} (${changePct.toFixed(1)}% of position)`,
      { name: 'pnl-alert' },
    );
  }
});

margin_warning — High margin usage

Fires when margin usage exceeds 80% of equity. After the first trigger, it only fires again if margin usage increases by another 5 percentage points (prevents spam). Resets when margin drops back below 80%.

Payload: { marginUsedPct: number, equity: number, marginUsed: number }

When to use:

• Automated risk reduction (close smallest position to free margin)
• Alerting the user before liquidation risk
• Pausing new entries when margin is high

Example:

api.on('margin_warning', async ({ marginUsedPct, equity }) => {
  await api.publish(
    `🚨 Margin at ${marginUsedPct.toFixed(1)}% — equity: $${equity.toFixed(2)}. Consider reducing exposure.`,
    { name: 'margin-alert' },
  );
});

Choosing the Right Event — Quick Guide

Use case	Best event	Why
Alert when price crosses a fixed level	tick	Fires every poll — no minimum change threshold
React to price momentum/volatility	price_change	Provides relative change data between polls
Funding rate strategy	funding_update	Gives annualized rate directly
Auto TP/SL on new positions	position_opened	Fires exactly when a new position appears
Log when positions close	position_closed	Fires when position disappears
Track position scaling	position_changed	Fires on size changes only
Risk management — PnL spikes	pnl_threshold	Only fires on large moves (≥5% of position value)
Risk management — margin	margin_warning	Fires at 80%+ margin usage
Periodic task (DCA, rebalance)	api.every(ms, fn)	Better than tick for longer intervals

Client Methods Available

The api.client object exposes the full Hyperliquid SDK:

Trading: marketOrder(coin, isBuy, size), limitOrder(coin, isBuy, size, price), triggerOrder(coin, isBuy, size, triggerPx, isMarket), takeProfit(coin, isBuy, size, triggerPx), stopLoss(coin, isBuy, size, triggerPx), cancel(coin, oid), cancelAll(coin?)

Market Data: getAllMids(), getMetaAndAssetCtxs(), getRecentTrades(coin), getCandleSnapshot(coin, interval), getFundingHistory(coin), getPredictedFundings()

Account: getUserStateAll(), getOpenOrders(), getUserFills(), getUserFunding(), getHistoricalOrders(), getUserFees(), getUserRateLimit(), getSpotBalances()

Leverage: updateLeverage(coin, leverage, isIsolated?)

Example: Price Breakout

// ~/.openbroker/automations/breakout.ts
export default function(api) {
  const COIN = 'ETH';
  const BREAKOUT_PCT = 2;  // 2% move triggers entry
  const SIZE = 0.5;
  let basePrice = null;

  api.onStart(async () => {
    const mids = await api.client.getAllMids();
    basePrice = parseFloat(mids[COIN]);
    api.log.info(`Watching ${COIN} from $${basePrice} for ${BREAKOUT_PCT}% breakout`);
  });

  api.on('price_change', async ({ coin, newPrice }) => {
    if (coin !== COIN || !basePrice) return;
    const totalChange = ((newPrice - basePrice) / basePrice) * 100;

    if (Math.abs(totalChange) >= BREAKOUT_PCT && !api.state.get('inPosition')) {
      const side = totalChange > 0;  // true = long, false = short
      api.log.info(`Breakout! ${totalChange.toFixed(2)}% — entering ${side ? 'long' : 'short'}`);
      await api.client.marketOrder(COIN, side, SIZE);
      api.state.set('inPosition', true);
    }
  });
}

Example: Scheduled DCA

// ~/.openbroker/automations/hourly-dca.ts
export default function(api) {
  const COIN = 'ETH';
  const USD_PER_BUY = 100;

  // Buy $100 of ETH every hour
  api.every(60 * 60 * 1000, async () => {
    const mids = await api.client.getAllMids();
    const price = parseFloat(mids[COIN]);
    const size = parseFloat(api.utils.roundSize(USD_PER_BUY / price, 4));
    await api.client.marketOrder(COIN, true, size);
    const count = (api.state.get('buyCount') || 0) + 1;
    api.state.set('buyCount', count);
    api.log.info(`DCA #${count}: bought ${size} ${COIN} at $${price}`);
  });
}

Example: Margin Guardian

// ~/.openbroker/automations/margin-guard.ts
export default function(api) {
  api.on('margin_warning', async ({ marginUsedPct, equity }) => {
    api.log.warn(`Margin at ${marginUsedPct.toFixed(1)}% — reducing positions`);

    // Close the smallest position to free margin
    const state = await api.client.getUserStateAll();
    const positions = state.assetPositions
      .filter(p => parseFloat(p.position.szi) !== 0)
      .sort((a, b) => Math.abs(parseFloat(a.position.positionValue)) - Math.abs(parseFloat(b.position.positionValue)));

    if (positions.length > 0) {
      const pos = positions[0].position;
      const size = Math.abs(parseFloat(pos.szi));
      const isBuy = parseFloat(pos.szi) < 0; // Close short = buy, close long = sell
      api.log.info(`Closing smallest position: ${pos.coin} (${pos.szi})`);
      await api.client.marketOrder(pos.coin, isBuy, size);
    }
  });
}

Publishing to the Agent (Webhooks)

Use api.publish() to send messages back to the OpenClaw agent. This triggers an agent turn — the agent receives the message and can notify the user via their preferred channel, take trading actions, or log the event.

// Simple notification
await api.publish(`ETH broke above $4000 — current price: $${price}`);

// With options
await api.publish(`Margin at ${pct}% — positions at risk`, {
  name: 'margin-alert',           // appears in logs
  wakeMode: 'now',                // 'now' (default) or 'next-heartbeat'
  channel: 'slack',               // target channel (optional)
});

api.publish() returns true if delivered, false if webhooks are not configured (no hooks token). It requires OPENCLAW_HOOKS_TOKEN to be set (automatically configured when running as an OpenClaw plugin).

Example: Price alert automation with publish

// ~/.openbroker/automations/price-alert.ts
export default function(api) {
  const COIN = 'ETH';
  const THRESHOLD = 4000;

  api.on('price_change', async ({ coin, newPrice, changePct }) => {
    if (coin !== COIN) return;

    const crossed = api.state.get<boolean>('crossed', false);
    if (!crossed && newPrice >= THRESHOLD) {
      api.state.set('crossed', true);
      await api.publish(
        `${COIN} crossed above $${THRESHOLD}! Price: $${newPrice.toFixed(2)} (+${changePct.toFixed(2)}%)`,
      );
    } else if (crossed && newPrice < THRESHOLD) {
      api.state.set('crossed', false);
    }
  });
}

Running Automations

CLI:

openbroker auto run my-strategy --dry       # Test without trading
openbroker auto run ./funding-scalp.ts      # Run from path
openbroker auto run my-strategy --poll 5000 # Poll every 5s
openbroker auto list                        # Show available scripts
openbroker auto status                      # Show running automations

Plugin tools (for OpenClaw agents):

• ob_auto_run — { "script": "funding-scalp", "dry": true } — start an automation
• ob_auto_stop — { "id": "funding-scalp" } — stop a running automation
• ob_auto_list — {} — list available and running automations

Options:

Flag	Description	Default
--dry	Intercept write methods — no real trades	false
--verbose	Show debug output	false
--id <name>	Custom automation ID	filename
--poll <ms>	Poll interval in milliseconds	10000

Important notes for agents writing automations:

• Always test with --dry first before live trading
• Use api.state to track position state across restarts
• Use api.onStop() to clean up — close positions, cancel orders
• Use api.publish() to send alerts/events back to the OpenClaw agent — do NOT manually construct webhook requests
• The runtime catches errors per handler — one failing handler won't crash others
• Scripts are loaded from ~/.openbroker/automations/ by name, or from any absolute path
• All trading commands support HIP-3 assets (api.client.marketOrder('xyz:CL', true, 1))
• Automations persist across gateway restarts — they are automatically restarted when the gateway comes back up

Risk Warning

• Always use --dry first to preview orders
• Start with small sizes on testnet (HYPERLIQUID_NETWORK=testnet)
• Monitor positions and liquidation prices
• Use --reduce for closing positions only
