EURJPY 4H × sma cross Backtest

TL;DR

First establish a baseline with fixed fees/slippage. If equity is stable, fine-tune gradually.

Overview

This page documents a reproducible backtest for EURJPY / 4H / sma cross. We publish conditions, steps, and caveats so anyone can reproduce the same results. London–NY overlap often drives momentum for this cross.

Strategy & Market Fit

Works well in: one-directional trends / post-news momentum
Degrades in: thin liquidity hours / heavy congestion near key levels

Notes from the operator

Early London tends to improve signal reliability, while Tokyo noon often adds noise. Validate with your own data.

Failure patterns & mitigations

Too many signals → add session/time filters
Weak trend & whip-saws → avoid thin liquidity windows
Over-tuning → split IS/OOS, consider walk-forward
