La estrategia de seguimiento de tendencias del canal gaúcho es una estrategia de negociación de seguimiento de tendencias basada en el indicador del canal gaúcho. La estrategia tiene como objetivo capturar la tendencia principal del mercado, comprar y mantener posiciones en tendencias al alza y cerrar posiciones en tendencias a la baja. La estrategia utiliza el indicador del canal gaúcho para identificar la dirección y la intensidad de la tendencia, y determinar el momento de compra y venta mediante el análisis de la relación entre el precio y la subida del canal.
El indicador Gaussian Channel, desarrollado por Ehlers, es una herramienta de análisis de tendencias que utiliza la técnica de las ondas gaussianas en combinación con el rango verdadero (True Range). El indicador primero calcula los valores β y α en función del ciclo de muestreo y el número de puntos polares, luego procesa los datos en forma de filtro para obtener una curva de nivelación (Mid-Orbit).
La estrategia de seguimiento de tendencias del canal de Gauss es una estrategia de seguimiento de tendencias basada en la tecnología de las ondas de Gauss para obtener ganancias estables a largo plazo al capturar las principales tendencias del mercado. La estrategia utiliza los indicadores del canal de Gauss para identificar la dirección y la fuerza de la tendencia, al tiempo que ofrece funciones para reducir la latencia y la reacción rápida.

// 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.
