AFIRMA: Autoregressive Finite Impulse Response Moving Average
Info
The AFIRMA: Autoregressive Finite Impulse Response Moving Average is a Indicator for MetaTrader 5 that afirma (autoregressive finite impulse response moving average) utilizes a digital filter to accurately represent price movement, albeit with a slight time lag. Traditional smoothing functions, like polynomials or trigonometric series (similar to Fourier transforms), offer no lag but can sometimes provide a less precise depiction of price action.
Usage
This tool is typically used for enhancing chart analysis and decision making.
Platform
This Indicator works exclusively on MetaTrader 5 (both build 600+ and newer versions).
Setup
Place the downloaded file in MQL5/Indicators folder via File ? Open Data Folder in MetaTrader 5.
How to Install and Use AFIRMA: Autoregressive Finite Impulse Response Moving Average
1. Installation: Place your file in the MQL/Indicators folder via "Open Data Folder" and restart your terminal.
2. Loading: Find the indicator in the Navigator, drag it onto your chart, and configure the input parameters in the popup window.
3. Customization: Press Ctrl+I to open the indicator list, select your tool, and click "Properties" to change colors, levels, or visual styles.

AFIRMA (Autoregressive Finite Impulse Response Moving Average) utilizes a digital filter to accurately represent price movement, albeit with a slight time lag.Also recommended: digital filters - separate - similar indicator with strong performance on MetaTrader 5.
Traditional smoothing functions, like polynomials or trigonometric series (similar to Fourier transforms), offer no lag but can sometimes provide a less precise depiction of price action.The AFIRMA moving average smooths price movements using a digital filter for all but the most recent candlesticks. The number of these recent candlesticks equals the filter's time lag.
For these latest candlesticks, smoothing is achieved through cubic spline fitting via the least squares method. Continuity of the combined moving average and its first derivative is maintained at the intersection of the two moving averages. This approach results in a smooth moving average that accurately tracks prices without any perceptible time lag.
Input Parameters:
Periods: Sets the low-frequency filter transmission width, calculated as 1/(2*periods).
Taps: Determines the number of delay units in the filter. This value must be an odd number, signifying the number of price points required to calculate the new smoothed MA value.
Window: Selects the filter approximation method:
window=1 - Rectangular window
window=2 - Hanning window
window=3 - Hamming window
window=4 - Blackman window
window=5 - Blackman-Harris window
The initial segment of the MA, calculated using the digital filter, is represented by the blue-violet curve. The subsequent segment, derived from cubic spline fitting, is displayed as the red curve.
