이 전략은 주로 주가가 단기적으로 과판될 때 역동향 기회를 찾기 위해 이동평균의 원리를 활용한다. 빠른 이동평균이 느린 이동평균보다 낮을 때 주가가 하향 추세에 있음을 나타낸다. 가격이 빠른 이동평균을 일정 마진으로 넘으면 하향이 제한되고 반등이 발생할 가능성이 있다. 이 전략은 가격이 빠른 이동평균보다 다시 넘을 때 긴 거리를 통해 그러한 과판 반등을 포착하는 것을 목표로 한다.
8EMA와 같은 빠른 이동 평균을 설정하고 20SMA와 같은 느린 이동 평균을 설정합니다.
SMA가 EMA 위에 있을 때 상승 추세를 나타냅니다. SMA가 EMA 아래에 있을 때 하락 추세를 나타냅니다.
가격이 EMA를 어느 정도 넘어서면 (예를 들어 2~10%) 주가가 과잉 판매되고 반등이 더 가능성이 높습니다.
가격이 EMA를 넘어서면 구매 신호가 발산됩니다.
EMA 근처에 스톱 로스를 설정하거나 중간 SMA (예: 50SMA) 근처에서 수익을 취하거나 수익을 취하는 비율을 사용합니다.
가격이 EMA 아래로 넘어갈 때 청산합니다.
이동평균의 신뢰할 수 있는 원리를 이용합니다.
빠른 EMA와 과잉 매출 마진이 반격 가능성을 높여줍니다.
사용자 정의 가능한 스톱 로스 및 취득 리스크 컨트롤
유연한 포지션 크기는 다른 위험 욕구에 맞습니다.
실패한 반등은 매출액 과잉 판매에도 불구하고 여전히 발생할 수 있습니다.
이동평균은 지연이 있고 지역 반등을 놓칠 수 있습니다.
EMA 근처에서 손해를 막는 것은 변동성 때문에 쉽게 멈출 수 있습니다.
몇 가지 수동 매개 변수 조정이 필요해서 결과에 큰 영향을 미칩니다.
결과는 가축 채집과 상관관계가 있습니다.
트렌드 필터를 추가하여 역 트렌드 트레이드를 피합니다.
확률을 높이기 위해 볼륨 필터를 추가합니다.
정적 대신 동적 후속 스톱 손실을 고려하십시오.
의존도를 줄이기 위해 최적의 파라미터 세트를 연구합니다.
더 나은 선택을 위해 가축을 뽑는 것을 포함합니다.
이 전략은 명확한 논리를 가지고 있으며 전형적인 이동 평균 회전 시스템으로 이해하기 쉽습니다. 이점으로는 안정성과 위험 통제가 있으며 초보자에게 적합합니다. 그러나 여전히 회전 지점을 잘못 판단 할 위험이 있습니다. 추가 필터, 동적 정지, 매개 변수 최적화 등을 통해 개선하면 탄력성을 향상시킬 수 있습니다. 전반적으로 학습 할 가치가있는 건전한 단기 평균 회전 프레임워크를 예로 삼습니다.

Intro //This strategy is designed to allow you to catch the bounce or "SNAP Back" of a equity that has been in a downward trend. //Once the moving averages are in the order of 200SMA > 50 SMA > 34EMA > 20SMA > 8EMA, the strategy is setup. //Next you wait for a trigger of the closing price crossing over the 8EMA, while there is a desired gap size between the 8EMA and the 20SMA (2-10% of stock value preferred). //Exit position based on target profit reached (conservative sell half at 34EMA and engage a trailing stop loss for remainder or set static limit) or price crosses 8EMA or stop loss% //*)This code also allows you to determine your desired backtesting date compliments of alanaster //This code is the product of many hours of hard work on the part of the greater tradingview community. The credit goes to everyone in the community who has put code out there for the greater good. //The idea for the coding came from video I watched on YouTube presented by TradeStation called Snap Back - thank you guys for the inspiration. //UPDATE: I have coded the other side of the strategy to allow you to take advantage of the same set-up in an uptrend for Short plays.
