Capture every yen move with photo attachments
Snap screenshots of your chart setups, candlestick patterns, or order tickets and attach them directly to each USD/JPY trade record for instant visual context.
Trading USD/JPY demands precision, discipline, and a clear record of every decision you make. As one of the most liquid currency pairs in the forex market, the dollar-yen relationship responds to interest rate differentials, central bank policy shifts, and macroeconomic data releases from both the United States and Japan. Mantis gives USD/JPY traders a private, offline journal on iPhone to log entries, exits, and the reasoning behind each trade. Your data stays entirely on your device—no cloud sync, no external servers—so you maintain complete control over your trading history. Whether you're scalping intraday moves around Tokyo open or holding swing positions through Federal Reserve announcements, Mantis helps you capture patterns, refine your edge, and build the consistency that separates disciplined currency traders from impulsive ones.

Frequently asked questions
Why should I keep a journal specifically for USD/JPY trades?
A dedicated journal lets you isolate patterns unique to the dollar-yen pair—such as your performance during Tokyo hours versus New York, or how you handle yen volatility around central bank announcements. Over time, this focused record reveals which setups and sessions give you the highest probability edge.
How does Mantis keep my USD/JPY trade data secure?
Mantis stores every trade, screenshot, and note locally on your iPhone. There is no cloud synchronization and no remote backup, so your currency trading history never leaves your device unless you explicitly export it.
Can I attach charts or screenshots to my forex entries?
Yes. You can attach photos directly to each trade record—useful for capturing candlestick formations, support and resistance levels, or your broker's order confirmation for later review.
Does Mantis work offline for intraday USD/JPY scalping?
Absolutely. Because all data lives on your device, you can log and review trades anytime without an internet connection—ideal when you're trading on the move or in areas with limited connectivity.
Will journaling my USD/JPY trades improve my discipline?
Consistent journaling encourages you to document your reasoning before and after each trade, making it easier to spot emotional decisions, overtrading, or deviations from your plan. Many traders find that the simple act of writing down their process builds accountability and long-term improvement.
