지난 글에서는 필자가 작성한 소스코드만 소개를 하였다.
(코인원 API 프로그래밍 - 1)

이번 글에서는 함수 호출 방법과 리턴값을 알아보기로 하자.

재정거래 봇을 만드는 것이 목표이므로 관련된 것만 확인해보자.

coin_balance 함수 사용법

coin_balance 는 코인원 거래소의 본인이 보유하는 원화 및 코인에 대한 정보를 알려준다.

'avail'과 'balance'의 차이는

1. 'balance': 본인이 보유하는 해당 코인 및 원화에 대한 전체량을 의미
2. 'avail': 본인이 유용 가능한 량을 의미

예를 들어 BTC를 1개 매도에 걸어둔 상태에서 자신의 총 BTC가 3개라면
'balance'는 '3', 그리고 'avail'은 '2'라는 값이 기록되어 있을 것이다.

함수 호출

result=coin_balance()
print(result)
