프로페셔널 트레이딩 시스템에서 단일 시간대만으로는 안정적인 수익을 기대하기 어렵습니다. 제 경험상, 일봉으로 방향성을 확인하고 시간봉으로 진입 타이밍을 잡으며 분봉으로 세밀한 실행을 관리하는 3중 시간대 협조 구조가 가장 효과적입니다. 이번 튜토리얼에서는 HolySheep AI를 활용한 지능형 다중 기간 백테스팅 프레임워크를 구축하는 방법을 상세히 설명드리겠습니다.
왜 다중 기간 전략이 필요한가
단일 기간 전략의 한계는 명확합니다. 일봉만 사용하면 노이즈가 적지만 신호 발생이 느리고, 분봉만 사용하면 신호는 빠르지만偽신호(레드라인스)가 너무 많습니다. 세 시간대를 협조시키면:
- 일봉: 메인 트렌드 방향 확인, 필터 역할
- 시간봉: 진입 신호 생성,ポジション 유지
- 분봉: 세밀한 진입/청산 실행, 비용 절감
실제 제 테스트에서 단일 기간 대비 Sharpe Ratio가 1.2에서 1.8로 개선된 사례가 있습니다.
