일부 외환 거래 데이터에서 SQL Server 2008의 쿼리에 문제가 있습니다. 나는 거래 테이블과 주문 테이블을 가지고있다. 무역은 2 개 이상의 주문으로 이루어져야합니다. DDL 스키마 및 아래의 샘플 데이터.쿼리에 문제가 발생했습니다.
내가하고 싶은 일은 각 거래의 이익/손실을 핍 (pips) 단위로 보여주는 쿼리를 작성하는 것입니다. 핍은 통화의 1/1000입니다. 그래서 1.3441과 1.3442 사이의 차이는 외환에서 1 pip입니다.
일반적으로 거래에는 하나의 주문 주문과 여러 차례의 주문이 있습니다. 예를 들어, 1.6100의 환율로 GBP/USD 통화 쌍을 3 개 구매 한 다음 1.6150, 1 lot을 1.6200, 1 lot을 1.6250으로 판매하면 이익은 (1.6150 - 1.6100) + (1.6200 - 1.6100) + (1.6250 - 1.6100) 또는 50 + 100 + 150 = 300 pips 이익
무역은 다른 방향으로 갈 수도 있습니다 (단락). 예를 들어 통화 쌍은 나중에 저렴한 가격으로 다시 구매하기 전에 먼저 판매 될 수 있습니다.
나는 다음을 반환하는 쿼리 싶습니다
tradeId, currencyPair, profitInPips
그것은 매우 간단 쿼리처럼 보인다, 그러나 그것은 지금 저를 벗어난 것. 사전에 어떤 도움
