Kalman Moving Average For Loop
Key Features of the Indicator:
Flexible Moving Average Calculation (calcMovingAverage):Description: Allows users to select from 10 moving average types (SMA, EMA, DEMA, TEMA, WMA, VWMA, SMMA, HMA, LSMA, ALMA) to process the input price source (pricesource, default: close).
Parameters:
maType: User selects the moving average type (default: HMA).
period: Length of the moving average (default: 14).
almaSigma: Sigma parameter for ALMA (default: 5).
Purpose: Provides versatility in analyzing price trends, with the chosen moving average (maValue) used for comparison with the smoothed Kalman filter output.
Kalman Filter for Price Smoothing:
Description:
Applies a Kalman filter to the price source to produce a filtered price (kalmanFilteredPrice), which is further smoothed using an HMA to create smoothedKalmanPrice.
Parameters:
process_noise: Controls system model noise (default: 0.01).
measurement_noise:
Controls measurement noise (default: 3).
N: Filter order, determining the number of state estimates (default: 3).
smooth_period: HMA period for smoothing kalmanFilteredPrice (default: 9).
Purpose: Reduces noise in price data, providing a smoother trend line for signal generation and plotting.
Historical Analysis with For-Loop:
Description: Uses a for-loop to calculate the average of calcMovingAverage values over a user-defined historical range (from to to_) for historical bars of the price source (pricesource).
Parameters:
from: Start of the historical range (default: 1).
to_: End of the historical range (default: 25).
Purpose: Computes an average moving average (avgMa) over the specified range to compare with the smoothed Kalman price for signal generation.
Error Handling and Robustness:
Description: Includes checks for na values in the for-loop to ensure only valid calcMovingAverage values contribute to the average (avgMa). Resets signal and plot variables each bar to prevent carryover.
Purpose: Ensures reliable calculations and prevents errors from invalid data.
