• true if an open position exists for the specified symbol and side.
• false if no such position exists.

Parameters

• symbol: The ticker symbol of the asset to check.
• side: The side of the position to check, either “long” or “short”.

} else {
  console.log(`Already have a long position in ${symbol}`);
}
