Discovery Sniper(Cortex preset).
A Cortex agent preset, not a price setup. It wakes on a fresh, open-interest-confirmed Noteworthy Flow print on cheap, short-dated calls in its watchlist, and follows the print's momentum if the tape agrees.
How it enters
Cortex agent playbook · Cortex agent preset
- A new Noteworthy Flow print appears in Discovery on one of the agent's symbols.
- The print is open-interest confirmed: the day's volume exceeded existing open interest, confirmed shortly after the print.
- The print is on calls, with a low premium and a short-dated expiration.
- The agent then checks whether the underlying is holding or extending in the direction of the print, and trades the printed contract or a nearby strike in the same expiration.
Regime context
- Discovery Sniper keys on flow, not on a gamma level, so the GEX Rating is context rather than a gate.
- Read the rating as a volatility regime: momentum tends to travel further at Rating 1-2 (negative gamma) and tends to be damped at Rating 4-5 (positive gamma). It is never a bullish or bearish read.

When it stops
- The print is stale, or the underlying has already moved well past where the print happened.
- The option's spread is too wide, or the contract is a far out-of-the-money lottery ticket.
- Momentum stalls after entry; the preset is built for intraday holds and does not hold a same-day print into the final minutes of the session.
- By design, most wakes end in a skip.

Common questions
Does Discovery Sniper trade every Noteworthy Flow print?
No. It only wakes on fresh, open-interest-confirmed prints on cheap, short-dated calls in its watchlist, and then checks the tape. Most wakes end in a skip by design.
Is the Discovery score a win probability?
No. It is a move-potential score that ranks how much a print stands out, not how likely a trade is to work. The Discovery score methodology explains what goes into it.
Is Discovery Sniper the same as Charm Sniper or Flow Sniper?
No. Discovery Sniper is a preset that wakes on Noteworthy Flow prints. Charm Sniper is a marketplace agent built on the Charm Stack at Anchor setup, and Flow Sniper is a separate preset focused on unusual flow, sweeps and large premium. The Setups Library hub lists every Sniper name and what it is.
