Fixing My Least-Winning MT5 EA: Tokyo Swing Trend (USDJPY H1) — Why Exits, Trailing, and Sizing Matter More Than Entries

I break down my “least winning” MT5 EA (Tokyo_SwingTrend_USDJPY_H1) and explain the real reasons it struggles: an ambitious 2.5R target paired with RSI pullbacks, a too-tight ATR trailing stop, and fixed minimum lot sizing. I also share practical, code-ready optimization directions: 1.5R–1.8R targets, trailing start at 1.5R with wider steps, equity-risk position sizing, and session/time logic driven by data.
