What a scored tape looks like
Illustrative example — not live market data.
The problem
Right now, you find out last.
The candle's already green. Your alert finally buzzes. The headline breaks — and the move already happened. That's the order Catalyst is built to catch, because it printed on the tape long before any of that.
Institutions don't trade the headline; they trade ahead of it, in size, through the options market. That footprint is public — it's just buried under millions of prints a day. Closing that gap is the whole point of Catalyst.
The toolkit
More than a feed — a full read on the tape.
Flow is the start. Gamma walls, 0DTE, contract-level context, and institutional positioning turn the whole tape into an edge you can work every session. Included with Pro and Elite.
Real-time options flow
Volume and premium concentration across the US options chain — filtered, scored, and ranked so the crowded strikes surface first.
Confidence, scored 0–100
Every print gets a score from premium paid, IV context, volume vs. average, and how the ticker has behaved before. We rank what matters.
Gamma exposure (GEX)
Dealer gamma walls and the flip level — where market-makers defend price, and where a move can accelerate once it breaks through.
0DTE mode
Same-day-expiration flow, isolated on demand — the fastest, highest-conviction prints of the session, without the longer-dated noise.
Contract Check
Paste any contract and get a plain-English read: what the flow implies, the risk, and what to watch — before you ever act on it.
Institutional OI tracker
Long-dated open-interest build — where the big, patient positioning is quietly stacking up, weeks and months out.
How we close the gap
We scan. We score. You decide.
Three steps stand between an institution's order and your screen. Here's what happens in the seconds after it prints.
We scan
The full US options chain — volume and premium concentration, implied volatility, put/call imbalances — scanned daily across thousands of tickers.
We score
Each print earns a 0–100 confidence score from premium, IV context, volume, and how the ticker has behaved before. The noise sinks; the real orders rise to the top.
You decide
You see exactly what the smart money did, in plain language, with the full context. No execution, no advice — the call is always yours.
What you decide on
This is one order, scored and explained.
No black box. Every number that feeds the score is right there — so you can read the order the way the desk that placed it would.

Hurried call buying into earnings — but options are pricey.
From the desk
Traders who stopped finding out last.
“I used to scan three tools every morning. Now I open Catalyst and the unusual flow is already ranked. It saves me an hour before the bell.”
“The confidence score finally tells me what's worth a second look. I'm not drowning in the tape anymore.”
“What sold me: I can see exactly how every score is calculated. No black box, no hype — just the order flow.”
Reviews reflect experience with the platform, not investment results. Catalyst is watch-only and does not provide trade recommendations.
