EURUSD One-Step Forecasting with HP Filtering and Stability Checks

Summary

The article demonstrates a one-step-ahead EURUSD H1 forecasting workflow using EViews for econometric modeling and an MQL4 Expert Advisor to evaluate forecasts. It examines quote distributions and autocorrelation, applies unit-root testing, and uses a Hodrick–Prescott filter to separate a deterministic component from residual variation. A regression combines the filtered series with lagged differences, and its output is used to form forecasts and assess trading outcomes.

The author finds remaining autocorrelation in the residuals, questions the model's adequacy, and describes the initial system as primitive. Profit-factor charts from samples of different lengths differ, which the article interprets as evidence of instability. The example is based on a short historical period and contains statistical caveats, including a weak coefficient estimate; it does not support a claim of durable forecast accuracy or profitability. Its value is chiefly methodological: it shows diagnostics and out-of-sample-style checks that can expose model weaknesses.

Key ideas

• The workflow combines econometric forecasting in EViews with evaluation through an MQL4 Expert Advisor.
• The Hodrick–Prescott filter is used to separate a deterministic component before regression modeling.
• Distribution, autocorrelation, and unit-root checks are applied to quotes and model residuals.
• Residual autocorrelation and differing profit-factor results across sample lengths raise concerns about model stability.
• The short historical demonstration reports a negative, inconclusive outcome rather than establishing a robust trading method.
