EUR/CHF

EUR/CHF is statistically one of the cleanest mean-reversion surfaces in the major cross market. The fundamental reason is straightforward: the Swiss and eurozone economies are tightly integrated — Switzerland exports roughly 50% to the EU — which means the EUR/CHF rate is persistently anchored by purchasing power parity rather than diverging policy cycles.

The SNB adds a further mean-reversion force. The Swiss National Bank has demonstrated consistent willingness to intervene when CHF strengthens excessively, providing an implicit floor under EUR/CHF that no other major pair has. This is not a guarantee — the 2015 peg removal proved the SNB can and does change policy — but in normal operating windows it suppresses extreme downside moves.

For EA traders, EUR/CHF’s primary characteristic is its low average daily range (~50 pips) relative to European majors (EUR/USD ~75 pips, GBP/USD ~100 pips). This makes it unsuitable for strategies that require large trend moves but ideal for mean-reversion and grid EAs that profit from price returning to equilibrium. The Mean Revert Range V1 EA in this catalogue is designed specifically for this pair.

Important caveat: the January 2015 SNB floor removal produced a 3,000-pip move in 20 minutes, wiping out accounts across the industry. The backtest period for all EAs on this catalogue starts 2020-01-01, explicitly avoiding that 6-sigma event. Current account holders should understand that macro policy reversals can produce tail risk outside any backtest model.
