Frequently asked questions
Why journal S&P 500 ETF trades specifically?
The S&P 500 ETF is one of the most liquid instruments in the world, but that liquidity can mask poor habits. A journal helps you identify which setups—momentum breakouts, mean reversion, volatility spikes—align with your actual profitability, so you stop trading noise and focus on repeatable edges.
How do I use Mantis to improve my SPY trading?
After each trade, log your entry and exit prices, attach a chart screenshot, and note the market context—was it a gap play, a Fed announcement, a technical breakout? Over weeks, review your tagged trades to see which conditions consistently yield profit and which drain your account.
Does Mantis sync my journal across devices or to the cloud?
No. Mantis stores your trading journal locally on your iPhone only. There is no iCloud sync, no cloud backup, and no server upload. Your data stays private and under your control at all times.
Can I track multiple S&P 500 ETF tickers in one journal?
Yes. Whether you trade SPY, VOO, IVV, or other S&P 500 ETFs, you can log each position separately, tag them by ticker or strategy, and filter your history to compare performance across different instruments or timeframes.
How quickly can I log a trade on mobile?
Mantis is designed for speed. Open the app, tap to create a new entry, fill in your trade details, attach a screenshot if you want, and save—all in under a minute. The faster you capture the context, the more accurate your future analysis will be.
