Moving averages with HP filter
A systematic foreign exchange (fx) approach—Moving averages with HP filter—defined by explicit rules, testable on history, and fragile when costs or regimes change.
Overview
In Subsection 3 we discussed a trading strategy for stocks wherein the trading signal is based on 2 intersecting (shorter and longer) moving averages. A similar approach can be applied to FX as well.
Moving averages with HP filter sits in the Foreign Exchange (FX) chapter of the systematic catalog. On QUSXFI we treat it as a testable hypothesis: specify entries, exits, sizing, and costs—then ask whether edge survives out-of-sample scrutiny.
Discretionary traders often arrive at similar ideas intuitively; the quantitative version forces you to write the rule before you see the next bar. That discipline is what makes results reproducible—or exposes them as luck.
