Open Broker - Hyperliquid Trading Skill

Execute trading operations on Hyperliquid DEX with builder fee support.

Quick Start (Automated Onboarding)

Run these two commands to get started:

bash

npm install
npx tsx scripts/setup/onboard.ts

This will automatically:

•Generate a new trading wallet
•Create .env with your private key
•Approve the builder fee (free, no funds needed)
•Display your wallet address to fund

After onboarding, fund your wallet:

•Send USDC to your wallet address on Arbitrum
•Deposit to Hyperliquid at https://app.hyperliquid.xyz/
•Start trading!

Manual Setup (Alternative)

If you prefer manual setup or have an existing wallet:

•Install dependencies: npm install

•Copy and configure environment:

bash

cp config/example.env .env
# Edit .env with your private key

•Approve builder fee:

bash

npx tsx scripts/setup/approve-builder.ts

Builder Fee

Open Broker charges a 1 bps (0.01%) builder fee on trades to fund development. The onboarding script handles this automatically. To check or manage manually:

bash

# Check if approved
npx tsx scripts/setup/approve-builder.ts --check

# Approve (must use main wallet, not API wallet)
npx tsx scripts/setup/approve-builder.ts

Order Types

Limit Orders vs Trigger Orders

Limit Orders (limit-order.ts):

•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 (trigger-order.ts, set-tpsl.ts):

•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	Use
Buy at specific price below market	Limit order
Sell at specific price above market	Limit order
Stop loss (exit if price drops)	Trigger order (SL)
Take profit (exit at target)	Trigger order (TP)
Add TP/SL to existing position	`set-tpsl.ts`
