Usage Example

Opening a Trade

from ostium_python_sdk import OstiumSDK
from dotenv import load_dotenv

# Load environment variables if using .env file
load_dotenv()

# Get private key from environment variable
private_key = os.getenv('PRIVATE_KEY')
if not private_key:
    raise ValueError("PRIVATE_KEY not found in .env file")

rpc_url = os.getenv('RPC_URL')
if not rpc_url:
    raise ValueError("RPC_URL not found in .env file")

# Initialize SDK
config = NetworkConfig.testnet()
sdk = OstiumSDK(config, private_key)

# Or initialize with explicit private key & rpc url
# sdk = OstiumSDK(
#     network="arbitrum",
#     private_key="your_private_key_here",
#     rpc_url="https://arb1.arbitrum.io/rpc"
# )

# Get all available pairs
pairs = await sdk.subgraph.get_pairs()

print("\nPair Information:")

for pair in pairs:
    # Get detailed information for each pair from the Graph API
    pair_details = await sdk.subgraph.get_pair_details(pair['id'])
    print("\nPair Details:")
    print("----------------------------------------")
    # Print all available fields in pair_details
    for key, value in pair_details.items():
        print(f"{key}: {value}")
    print("----------------------------------------")


# Define trade parameters

  print(f"Trade successful! Transaction hash: {receipt['transactionHash'].hex()}")

  # Wait for the transaction to be confirmed
  await asyncio.sleep(10)

  # Get public address from private key

  open_trades = await sdk.subgraph.get_open_trades(trader_public_address)
  for trade_index, trade_data in enumerate(open_trades):

          "No open trades found. Maybe the trade failed? enough USDC and ETH in the account?")
  else:
      opened_trade = open_trades[len(open_trades) - 1]
      print(f"Opened trade: {opened_trade}\n")

      sdk.ostium.update_tp(
          opened_trade['pair']['id'], opened_trade['index'], latest_price * 1.02)
      print(f"Trade Take Profit set to 2% above the current price!\n")

      await asyncio.sleep(10)

      sdk.ostium.update_sl(
          opened_trade['pair']['id'], opened_trade['index'], latest_price * 0.99)
      print(f"Trade Stop Loss set to 1% below the current price!\n")

      await asyncio.sleep(10)

      receipt = sdk.ostium.close_trade(
          opened_trade['pair']['id'], opened_trade['index'])
      print(
          f"Closed trade! Transaction hash: {receipt['transactionHash'].hex()}\n")



except Exception as e:
  print(f"Trade failed: {str(e)}")
