Why EMA Crossover Works on USDJPY
The EMA crossover is the textbook trend-following strategy. A fast EMA (typically 9–13) reacts to recent price; a slow EMA (21–50) tracks the broader trend. The crossover marks a regime change. It captures large directional moves in trending markets and fails predictably in chop — making it easy to layer with a regime filter.
USD/JPY is heavily driven by yield differentials and BoJ policy. Slow-grinding trends on the daily, predictable Tokyo-session ranges — a strong fit for swing and trend bots.
Forex pairs trade with tight spreads, deep liquidity, and predictable session-based behavior. The strategy below earns its edge during the active sessions for this pair.
