This ongoing series compiles viewpoints that can be used to judge trades based on actual USD/JPY charts and historical data (including convenient timeframes, days, and how to use horizontal lines). In some issues, a quick-reference table and a calendar (PDF) are attached for pre-trade checks. The chart lines are automatically drawn with the MT5 indicator "Okome Horizontal Line" (a product I sell). ※ It does not mean that past data will necessarily be the same in the future. This is not a recommendation to buy or sell.
