SunPerp Perpetual Futures Trading

Overview

This skill enables AI agents to trade USDT-margined perpetual futures on SunPerp, the perpetual futures DEX on the TRON blockchain. It provides scripts for:

• Market data : Prices, order books, candlesticks, funding rates
• Account management : Balances, fee rates, trading bills
• Order management : Place, cancel, and query orders (market, limit, post-only)
• Position management : View positions, set leverage, set position mode, close positions

All scripts communicate with the SunPerp REST API at https://api.sunx.io.

Prerequisites

1. Environment Setup

Install Node.js dependencies from the skill directory:

cd sunperp-skill
npm install

2. API Key Configuration

The user must create API keys at https://www.sunperp.com/futures/api-manage/ and set them as environment variables:

export SUNPERP_ACCESS_KEY="your_access_key"
export SUNPERP_SECRET_KEY="your_secret_key"

[!CAUTION] Never hardcode API keys in commands or files. Always read them from environment variables. If the environment variables are not set, prompt the user to set them before proceeding.

3. Verify Setup

Run a public endpoint to verify connectivity (no API key needed):

node scripts/market.js ticker contract_code=BTC-USDT

Then verify authenticated access:

node scripts/account.js balance

Usage Instructions

Contract Code Format

SunPerp contracts follow these naming patterns:

Popular perpetual contracts: BTC-USDT, ETH-USDT, TRX-USDT, SOL-USDT, SUN-USDT, DOGE-USDT, XRP-USDT.

Position Modes

SunPerp supports two position modes:

• single_side (One-way): Use position_side=both for all orders. The side field determines direction.
• dual_side (Hedge): Must specify position_side=long or position_side=short. Allows simultaneous long and short positions.

Check the current mode before trading:

node scripts/position.js get_mode

Margin Mode

The API uses cross margin (margin_mode=cross) as the standard mode. All order and position scripts default to cross margin.

Script Reference

All scripts are located in the scripts/ directory and invoked as:

node scripts/<script>.js <command> [key=value ...]

Examples

Example 1: Check Price and Open a Long Position

User: "Buy 5 contracts of BTC-USDT at market price"

Agent steps:
1. Check the current price:
   node scripts/market.js ticker contract_code=BTC-USDT

2. Check account balance:
   node scripts/account.js balance

3. Confirm with user: "BTC-USDT is currently at $96,500. You have $10,000 available margin.
   Placing a market buy for 5 contracts. Proceed?"

4. After user confirms, place the order:
   node scripts/order.js place contract_code=BTC-USDT side=buy type=market volume=5

5. Verify the position was opened:
   node scripts/position.js list contract_code=BTC-USDT

6. Report: "Opened long position: 5 BTC-USDT contracts at $96,502 avg entry.
   Liquidation price: $48,251. Current unrealized PnL: $0."

Example 2: Set Leverage and Place a Limit Order

User: "Set leverage to 20x on ETH-USDT and place a limit buy at $3,200 for 10 contracts"

Agent steps:
1. Set leverage:
   node scripts/position.js set_leverage contract_code=ETH-USDT lever_rate=20

2. Check current price for context:
   node scripts/market.js ticker contract_code=ETH-USDT

3. Confirm with user: "Leverage set to 20x. ETH-USDT is at $3,350.
   Placing limit buy for 10 contracts at $3,200. Proceed?"

4. After user confirms, place the order:
   node scripts/order.js place contract_code=ETH-USDT side=buy type=limit volume=10 price=3200

5. Verify the order was placed:
   node scripts/order.js open_orders contract_code=ETH-USDT

6. Report: "Limit buy order placed: 10 ETH-USDT at $3,200. Order ID: 987654321. Status: open."

Example 3: Close a Position and Check PnL

User: "Close my BTC-USDT position"

Agent steps:
1. Check existing position:
   node scripts/position.js list contract_code=BTC-USDT

2. Report position details and confirm:
   "You have a long position of 5 BTC-USDT contracts. Entry: $96,502, Current: $97,100.
   Unrealized PnL: +$2.99. Close at market? Proceed?"

3. After user confirms, close:
   node scripts/order.js close contract_code=BTC-USDT position_side=both

4. Verify:
   node scripts/position.js list contract_code=BTC-USDT

5. Report: "Position closed. Realized PnL: +$2.95 after fees."

Example 4: Monitor Funding Rate

User: "What's the funding rate for TRX-USDT?"

Agent steps:
1. Get funding rate:
   node scripts/market.js funding contract_code=TRX-USDT

2. Report: "TRX-USDT funding rate: 0.01% (next funding in 2h 15m).
   Positive rate means longs pay shorts."

Error Handling

Common Error Scenarios

Error Handling Pattern

When a script returns an error:

1. Parse the error message from the JSON response (code, message, or error-msg fields)
2. Explain the error to the user in plain language
3. Suggest a specific corrective action
4. Do NOT retry automatically for trade operations — always confirm with the user

Agent Safety Locks

Two mandatory safety mechanisms are enforced at the script level to prevent catastrophic losses. Both are configured in resources/sunperp_config.json under the safety key.

1. Max Leverage Cap

The cap is enforced in two places:

• position.js set_leverage — rejects any lever_rate above the cap before calling the API.
• order.js place — if lever_rate is passed inline, it is validated before the order is submitted.

If the agent attempts to exceed the cap, the script exits with a clear error:

ERROR: Leverage 50x exceeds the agent safety cap of 20x.
Adjust max_leverage in sunperp_config.json to raise this limit.

To change the cap, edit safety.max_leverage in the config file. This is an operator-level setting — the agent cannot change it at runtime.

2. Mandatory Stop-Loss

When required is true, every position-opening order (i.e., not reduce_only) must include a stop-loss:

• Ifsl_trigger_price is provided: validated to be within max_percent of the reference price.
• If omitted on a limit order : auto-calculated at default_percent below entry (long) or above entry (short).
• If omitted on a market order : the script fetches the current market price and auto-calculates. If the price fetch fails, the order is rejected with an instruction to provide sl_trigger_price explicitly.

Example — auto stop-loss on a limit long:

# Limit buy at $95,000 — SL auto-set to $90,250 (5% below)
node scripts/order.js place contract_code=BTC-USDT side=buy type=limit volume=1 price=95000

Example — explicit stop-loss:

node scripts/order.js place contract_code=BTC-USDT side=buy type=market volume=1 sl_trigger_price=90000

Example — rejected (SL too wide):

# 30% distance exceeds max_percent of 25%
node scripts/order.js place contract_code=BTC-USDT side=buy type=limit volume=1 price=95000 sl_trigger_price=66500

[!NOTE] The reduce_only flag (close-position orders) is exempt from the stop-loss requirement since those orders are already reducing risk.

Security Considerations

[!CAUTION] Private Keys & API Secrets: Never log, display, or store API secret keys. Read them exclusively from environment variables.

[!WARNING] Trade Confirmation : Always confirm the following with the user BEFORE executing any trade:

• Contract code and direction (long/short)
• Order type (market/limit) and volume
• Price (for limit orders)
• Current leverage setting
• Estimated margin requirement

Security Checklist

• API keys loaded from environment variables only
• No secrets in command output or logs
• Trade confirmations shown before execution
• Leverage changes confirmed before applying
• Leverage never exceeds safety.max_leverage cap
• Every position-opening order has a stop-loss attached
• Position mode changes confirmed before applying
• Close-all operations require explicit user confirmation
• Cancel-all operations require explicit user confirmation
