Frequently asked questions
Why journal Nasdaq-100 trades specifically?
The Nasdaq-100's concentration in technology and growth stocks creates unique volatility patterns, sector correlations, and sentiment-driven moves. A journal helps you identify which setups match your risk tolerance and which market conditions favor your style.
Does Mantis sync my journal to iCloud or any cloud service?
No. Mantis stores all journal entries locally on your iPhone only. Nothing is uploaded to iCloud, external servers, or cloud backup services.
Can I track futures, options, and ETF trades on the Nasdaq-100?
Yes. Mantis is instrument-agnostic—log any trade type, add custom tags for contract expiries or strike prices, and attach notes about entry and exit reasoning.
How does journaling improve my Nasdaq-100 trading?
Reviewing past trades reveals recurring mistakes, effective setups, and emotional triggers. Over time, you'll refine entry rules, stop-loss discipline, and position sizing tailored to index volatility.
Is my trade data visible to anyone else?
No. Because Mantis stores everything on-device only, your journal entries, P&L figures, and notes remain completely private and under your control.
