이 전략은 K 근접한 KNN 기계 학습 알고리즘을 사용하여 가격 추세를 예측한다. 다른 가격 계산 방법을 선택하여 HL2, VWAP, SMA 등과 같은 입력값과 다른 목표값을 선택하여 가격 움직임, VWAP, 변동율 등과 같은 평가 대상을 선택하여 KNN 알고리즘을 사용하여 현재 시장 상태에 가장 가까운 K의 역사 데이터 포인트를 찾아내고 K의 데이터 포인트의 트렌드 방향을 기반으로 다중 공간 예측을 수행한다. 동시에, 전략은 예측의 안정성을 높이기 위해 이동 평균을 사용하여 예측 결과를 부드럽게 처리한다.
이 전략은 KNN 기계 학습 알고리즘을 가격 추세 예측에 적용하여, 역사적 데이터와 통계 방법을 사용하여 시장 추세를 파악하고 거래 신호를 생성하는 방법을 보여줍니다. 전략의 장점은 그것의 적응성과 유연성이며, 매개 변수를 조정하여 성능을 최적화하고 다양한 시장 상황에 적응할 수 있습니다. 그러나, 전략의 위험은 주로 역사적 데이터의 품질과 대표성, 그리고 매개 변수 설정의 합리성에서 비롯됩니다.

Adjusting this number will affect the sensitivity of the trend line, with a higher value leading to a smoother line and a lower value resulting in a line that is more responsive to recent price changes."

Adjusting the smoothing period will affect how rapidly the trend line responds to price changes, with a larger smoothing period leading to a smoother line that may lag recent price movements, and a smaller smoothing period resulting in a line that more closely tracks recent changes."
