0DTE · SPX and SPXW
Built for the trade that expires today.
The same-day chain, a fast multi-leg ticket, today's gamma and today's flow, side by side in one console, on your own broker login.
Chain and ticket
Four legs from the 0DTE chain in a few clicks
Open the chain on today's expiry and click quotes: each click adds a leg to the ticket. An iron condor, a vertical or a strangle takes a few clicks. Price it at mid or at the natural price, or step it a tick at a time with − and +; the ticket shows the bid, mid and ask of the whole order.
Review shows the legs, the order, max loss, max profit and breakevens at expiry, and the broker's what-if margin and commission for each account. Any change to the order drops the Review, so what you send is what you checked.
Click bids and asks to build legs; the ticket shows risk at expiry and each account's broker what-if before Send.
Gamma
Where today's hedging pressure sits
Switch the gamma panel to 0DTE and see net dealer gamma for today's expiry alone, with the strike it pulls toward, the 0DTE magnet, next to the walls and the flip.
The by strike flow view adds today's signed flow to open interest at each strike, so you see how the day has moved the gamma map.
Filter gamma to 0DTE: call wall, put wall, flip and the 0DTE magnet.
0DTE flow
Who is buying today's options
Every 0DTE SPXW print is signed buy or sell from the bid and ask when it traded, turned into the hedge it implies and summed minute by minute for calls, puts and the total. Large prints are listed as they come.
Multi-leg prints are grouped into their packages and signed from the package's net price; a group that cannot be resolved stays unsigned rather than guessed.
SPXW prints signed by the quote at the print, summed each minute and by strike.
Expected move
How far the market expects today to go
The price chart's expected-move bar shows the move the at-the-money straddle prices for today's expiry, the next day, the week and the month. The chain can add an EM column for every expiry, and the volatility panel shows the next expiry's beside skew and the term structure.

Guard rails
Fast, but never blind
Every order goes through Review first. The broker's what-if is shown for each account on its own, never added up, and a changed price, quantity or leg sends you back to Review.
