Holt Double Exponential Smoothing - MetaTrader 5 Script | Trading Script Download - MT4/MT5 Resources

The name of this indicator may be a bit misleading. Holt bi-exponential smoothing is primarily used for forecasting, not averaging. A commonly used forecasting method is a linear forecast.

Like regression forecasting, biexponential smoothing forecasting is based on the assumption that the model consists of a constant plus a linear trend.

The estimates a and b at time T are based on the observations at time T and the estimates for the previous period T -1.

The expected value of the forecast for future periods is a constant plus a linear term that depends on the number of periods in the future.

To enable it to be used in both ways (as an average or as an "average" of forecasts), turn off the forecast part by setting the number of forecast bars to <= 0.

As typically used with the prediction part, it is strongly recommended not to use it in signaling mode. The forecast part is a subject of variation and can only be used as an estimate of the trend component of the double smoothing and not as a signal. Alerts in this indicator do not alert on changes in the forecast part, but on changes in the "past" part - this does not change as time passes.
