Example Implementation

import { SolanaAgentKit } from "solana-agent-kit";
import { PublicKey } from "@solana/web3.js";

async function rangerOperations(agent: SolanaAgentKit) {
  try {
    const apiKey = "YOUR_API_KEY";
    
    // Open a new long position on SOL
    const openTx = await agent.methods.openPerpTradeRanger({
      symbol: "SOL",
      side: "Long",
      size: 1.0,
      collateral: 10.0,
      apiKey
    });
    console.log("Open position transaction:", openTx);

    // Increase the position
    const increaseTx = await agent.methods.increasePerpPositionRanger({
      symbol: "SOL",
      side: "Long",
      size: 0.5,
      collateral: 5.0,
      apiKey
    });
    console.log("Increase position transaction:", increaseTx);

    // Decrease the position
    const decreaseTx = await agent.methods.decreasePerpPositionRanger({
      symbol: "SOL",
      side: "Long",
      size: 0.5,
      apiKey
    });
    console.log("Decrease position transaction:", decreaseTx);

    // Close the position
    const closeTx = await agent.methods.closePerpTradeRanger({
      symbol: "SOL",
      side: "Long",
      apiKey
    });
    console.log("Close position transaction:", closeTx);

    // Withdraw balance

Error Handling

try {
  const signature = await agent.methods.openPerpTradeRanger({
    symbol: "SOL",
    side: "Long",
    size: 1.0,
    collateral: 10.0,
    apiKey: "YOUR_API_KEY"
  });
} catch (error) {
  if (error.message.includes("insufficient funds")) {
    // Handle insufficient balance
  } else if (error.message.includes("slippage")) {
    // Handle price movement
  }
}

​
Best Practices

  1. API Key Management
    • Securely store and manage your Ranger API key
    • Never expose your API key in client-side code
    • Implement proper scoping and permissions for API keys
  2. Position Sizing
    • Use appropriate position sizes relative to your capital
    • Consider market volatility when determining leverage
    • Monitor positions regularly to manage risk
  3. Collateral Management
    • Maintain sufficient collateral to avoid liquidations
    • Use the withdrawCollateral function judiciously
    • Monitor health factors for positions
  4. Error Handling
    • Implement robust error handling for all API calls
    • Include retry logic for temporary failures
    • Monitor transaction status until confirmed
