La stratégie des moyennes mobiles adaptatives du canal de Gauss est une stratégie de trading quantitative qui utilise des techniques de filtrage de Gauss et des paramètres adaptatifs. Basée sur la théorie du filtre de Gauss proposée par John Ehlers, cette stratégie génère des signaux de trading fluides et adaptatifs en appliquant plusieurs calculs de moyennes mobiles exponentielles aux données des prix.
Les principes de la stratégie des moyennes mobiles adaptatives du canal de Gauss sont les suivants:
La stratégie des moyennes mobiles adaptatives du canal de Gauss présente les avantages suivants:
Malgré ses nombreux avantages, la stratégie des moyennes mobiles adaptatives du canal de Gauss comporte encore certains risques:
Les directions d'optimisation de la stratégie de moyenne mobile adaptative du canal de Gauss comprennent:
La stratégie des moyennes mobiles adaptatives de canal de Gauss est une stratégie de trading quantitative basée sur le filtrage et les paramètres adaptatifs de Gauss, qui génère des signaux de trading fluides et fiables en construisant dynamiquement des canaux de prix. La stratégie présente des avantages tels qu'une forte adaptabilité, une bonne capacité de suivi des tendances, une grande fluidité, une grande souplesse et une grande praticité.

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.
