Gaussian Channel Trend Following Strategy adalah strategi perdagangan trend-mengikuti berdasarkan penunjuk Gaussian Channel. Strategi ini bertujuan untuk menangkap trend utama di pasaran, membeli dan memegang kedudukan semasa trend menaik dan menutup kedudukan semasa trend menurun. Ia menggunakan penunjuk Gaussian Channel untuk mengenal pasti arah dan kekuatan trend dengan menganalisis hubungan antara harga dan jalur atas dan bawah saluran. Matlamat utama strategi adalah untuk memaksimumkan keuntungan semasa trend yang berterusan sambil meminimumkan kekerapan semasa pasaran perdagangan terhad jangkauan.
Inti dari Gaussian Channel Trend Following Strategy ialah Gaussian Channel indicator, yang dicadangkan oleh Ehlers. Ia menggabungkan teknik penapisan Gaussian dengan True Range untuk menganalisis aktiviti trend. Indikator pertama mengira nilai beta dan alpha berdasarkan tempoh pengambilan sampel dan bilangan kutub, kemudian menggunakan penapisan ke data untuk mendapatkan lengkung yang halus (garis tengah). Seterusnya, strategi mengalikan Julat Benar yang halus dengan pengganda untuk menjana saluran atas dan bawah. Apabila harga melintasi di atas / di bawah saluran atas / bawah, ia menjana isyarat beli / jual.
Gaussian Channel Trend Following Strategy adalah strategi perdagangan trend-mengikuti berdasarkan teknik penapisan Gaussian, yang bertujuan untuk menangkap trend pasaran utama untuk pulangan stabil jangka panjang. Strategi ini menggunakan penunjuk Saluran Gaussian untuk mengenal pasti arah trend dan kekuatan sambil menawarkan ciri untuk mengurangkan kelewatan dan memberikan tindak balas yang cepat. Kelebihan strategi terletak pada keupayaan trend-mengikuti yang kuat dan kekerapan perdagangan yang rendah. Walau bagaimanapun, ia juga menghadapi risiko seperti pengoptimuman parameter, pembalikan trend, dan pasaran terhad. Pengoptimuman masa depan boleh merangkumi menggabungkan penunjuk teknikal lain, pengoptimuman parameter dinamik, menambah modul kawalan risiko, dan analisis pelbagai jangka masa untuk meningkatkan lagi kekuatan dan keuntungan strategi.

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.
