가우시안 채널 트렌드 추적 전략은 가우시안 채널 지표에 기반한 트렌드 추적 거래 전략이다. 이 전략은 시장의 주요 트렌드를 포착하고, 상승하는 트렌드에서 구매하고 포지션을 보유하며, 하락하는 트렌드에서 평점을 관찰한다. 전략은 가우시안 채널 지표를 사용하여 트렌드의 방향과 강도를 식별하고, 가격과 채널 상하의 관계를 분석하여 구매 시점을 결정한다.
가우시안 채널 트렌드 추적 전략의 핵심은 가우시안 채널 지표입니다. 이 지표는 Ehlers에 의해 제안되었으며, 가우시안 파동 기술과 실제 범위 ((True Range) 를 결합한 트렌드 분석 도구입니다. 지표는 먼저 샘플링 주기와 극점 수에 따라 β 및 α 값을 계산한 다음 데이터를 필터링하여 평준화 곡선을 얻습니다.
가우시안 채널 트렌드 추적 전략은 가우시안 파동 기술을 기반으로 한 트렌드 추적 거래 전략으로, 시장의 주요 트렌드를 포착하여 장기적으로 안정적인 수익을 얻습니다. 전략은 가우시안 채널 지표를 사용하여 트렌드 방향과 강도를 식별하고, 지연 및 신속한 반응을 줄이는 기능을 제공합니다. 전략의 장점은 좋은 트렌드 추적 능력과 낮은 거래 빈도입니다. 그러나 또한 변수 최적화, 트렌드 전환 및 흔들리는 시장과 같은 위험에 직면합니다.

// This study is an experiment utilizing the Ehlers Gaussian Filter technique combined with lag reduction techniques and true range to analyze trend activity.
// Gaussian filters, as Ehlers explains it, are simply exponential moving averages applied multiple times.
// First, beta and alpha are calculated based on the sampling period and number of poles specified. The maximum number of poles available in this script is 9.
// Next, the data being analyzed is given a truncation option for reduced lag, which can be enabled with "Reduced Lag Mode".
// Then the alpha and source values are used to calculate the filter and filtered true range of the dataset.
// Filtered true range with a specified multiplier is then added to and subtracted from the filter, generating a channel.
// Lastly, a one pole filter with a N pole alpha is averaged with the filter to generate a faster filter, which can be enabled with "Fast Response Mode".
// Custom bar colors are included.
// Note: Both the sampling period and number of poles directly affect how much lag the indicator has, and how smooth the output is.
// Larger inputs will result in smoother outputs with increased lag, and smaller inputs will have noisier outputs with reduced lag.
// For the best results, I recommend not setting the sampling period any lower than the number of poles + 1. Going lower truncates the equation.
//-----------------------------------------------------------------------------------------------------------------------------------------------------------------
// Updates:
// Huge shoutout to @e2e4mfck for taking the time to improve the calculation method!
// -> migrated to v4
// -> pi is now calculated using trig identities rather than being explicitly defined.
// -> The filter calculations are now organized into functions rather than being individually defined.
// -> Revamped color scheme.
