The console: an SPX chain 14 days out, a put spread in the ticket with each paper account's broker margin and commission, and the gamma panel beside it. Demo chain and ticket, demo gamma.

The real console on demo data: a put spread from the chain to Review, with the broker’s what-if for each paper account.

Trade from the chain

Click a quote, get a ticket

Your broker’s what-if margin and commission for each account before Send, never added up.

Gamma

Where dealers have to hedge

Call wall, put wall, flip and 0DTE magnet for SPX, BTC and ETH.

0DTE flow

Who is buying today’s options

SPXW prints signed at the bid or ask, summed minute by minute.

Volatility

Surface, term and skew

Near-the-money skew refreshed about every 30 s, the wings every 3 min.

Your own algos

Write the rules, not a platform

A YAML algo is checked, backtested over past days and deployed paused.

Paper first

Nothing live by accident

Live trading needs a file the tester build never ships.

0DTE · SPX and SPXW

Trade today's expiry with today's map.

The same-day chain, a four-leg ticket with the broker’s what-if before Send, gamma filtered to 0DTE with its magnet, and 0DTE flow with multi-leg packages signed from their net price.

For 0DTE traders →

The console on a same-day SPX expiry: the 0DTE chain, an iron condor in the ticket with its Review, and the gamma panel filtered to 0DTE with the 0DTE magnet. Demo chain and ticket, demo gamma.

For asset managers

One decision, every client account.

Place a trade once across all your accounts, each sized by its own allocation. P&L and risk stay per account, never mixed, and every allocation change keeps who, when and why. Interactive Brokers today; more brokers coming.

For asset managers →

The Allocations table: two sample algos funded on two paper accounts, each with its own capital, most contracts and margin share, and the history of changes with their reasons. Demo data.

Your algos stay private: they live on your computer and are never shared. Coming an opt-in algo marketplace, for authors who choose to publish. Automation →

The 0DTE flow view: dealer hedge flow for calls, puts and the total through the morning, SPX beside it, and the large prints below. Made-up demo flow.

0DTE flow. Calls, puts and the hedge they imply, minute by minute.

The volatility surface: implied volatility by expiry and by distance from spot. Demo data.

Vol surface. Every expiry by distance from spot, as a level or against yesterday.

A sample iron condor algo written in YAML in the Draft tab, with Validate, Save, Backtest and Deploy, and the check passed.

Algos in YAML. Schedule, legs by delta, exits; validate and backtest before it trades.
