MANTIS

Watch. Wait. Strike.

You're not under-informed. You're out-timed.

Mantis is the trading-intelligence desk for serious independent traders — institutional options flow, fundamentals, risk, and a journal in one workflow. The edge is decision timing and a process that holds, not a faster tape.

Mantis — your market spotter
$48M just bought NVDA 200 calls.

Unusual call flow — the setup visible before the story broke.

The edge isn't more data. It's better timing — and a workflow that holds.

Too late

By the time it's a headline, the move has happened. You're reading about Tuesday's trade on Wednesday morning.

Fragmented workflow

Flow on one screen, risk on another, journal in a spreadsheet. The signal dies in the gaps between tabs.

Hidden risk

Account size isn't risk. A position without a stop isn't zero — it's the whole position, at 2am.

No attribution

Is your active trading actually outpacing your ETF core? Without attribution, you're guessing — expensively.

Who Mantis is for.

For the independent trader who already has a process and wants to see the setup clearly and on time — not a tip service, not a managed account, not for anyone waiting to be told what to do.

Detect the setup. Structure the trade. Close the day with a plan.

1

Surface the signal before the crowd confirms it.

Squeeze, breakout, and momentum scans run on your watchlist the second you tap — the name that triggered, the condition that fired, how strong it is.

2

Structure the trade before you strike.

Eight templates from long call to iron condor. Drop your strikes, read the payoff and the AI's structured analysis — anchored on the current Greeks.

3

End the day with a clear plan for tomorrow.

A nightly digest of what moved in your book and your watchlist — flow, earnings, regime shifts — distilled into the three things to act on at the open.

The intelligence layer the desk is built on.

Smart Money & Whale Activity

PRO

Daily institutional options flow plus 13F whale positioning — see what the desks are buying and what the funds own, before the crowd reads about it.

Learn more

Risk Manager

Capital at risk in dollars, R-multiples on every position, and concentration alerts that fire before a name becomes a problem — not after.

Learn more

Trade Journal & Attribution

Per-leg exits and AI context at entry, with attribution that answers the only question that matters: is your active book actually earning its keep?

Learn more

Correlation Matrix

See how your positions move together — and where your real, hidden concentration sits — with a Pearson matrix across your whole book.

Built for discipline, not hype.

Mantis is an information and research tool — not a broker, and not investment advice. Every signal, score, and valuation is descriptive analytics for your own research, never a prediction or a promise of returns. The guardrails are the product.

Common questions.

Is my data secure?
All data is encrypted in transit and at rest. We never sell your trade data, period.
Do I need a brokerage account?
No. Mantis is a research and journaling tool. You log your trades after they happen — we don't connect to a broker.
What's the difference between Free, Essential, and Pro?
Free gets you the trade journal, position sizer, and risk manager. Essential adds the screener and sentiment. Pro unlocks Smart Money flow, whale tracking, macro regime, AI earnings summaries, and the Signal Scorecard. See the pricing page for the full breakdown.
Is a card required for the trial?
Yes — we use Stripe to verify your card before starting the 7-day trial. We won't charge until day 8, and we send a reminder email 3 days before that.
Where is Mantis available?
Mantis runs in any modern browser, anywhere in the world. All plans are priced in USD.

Watch. Wait. Strike.

Trade with the same intelligence the desks use.

Create your free account in minutes — trade journal, live market data and the core toolkit cost nothing. Upgrade to Essential or Pro whenever you want more.
