One click in, one click out

Left-click a price to buy it, right-click to sell it. The order goes at the price you clicked, for the stake in the box — no ticket, no dialog, no second window. FLATTEN closes the position from the same screen, and the chip tells you what closing right now is worth before you touch it, priced against the bid you would actually hit rather than a mid nobody can trade.

Polymarket has no market order. FLATTEN sends a limit that takes what it can immediately and cancels the rest, and the terminal says so rather than pretending the fill is guaranteed.

Matched pairs turn back into cash

Holding both sides of a market is holding a dollar in two pieces. The terminal watches for that pair and merges it back into cash for you, checking every couple of seconds, and only when the merge is worth more than it costs to make. It is on out of the box, and it has a switch that makes it wait until you ask.

Orders that look after themselves

Move a resting order by replacing it in place, instead of cancelling and queuing again from the back. Before it goes, the ticket tells you which one it is: filling now, or joining the queue. A stop-loss, a tick offset, fill-or-kill and an inactivity cancel are built in, so an order can hold its own while you are watching another market.

The book is not the whole market

The tape prints every trade on the market as it happens, and FLOW does it across the venue rather than only where you are standing. Holders shows who is on each side and for how much. The market's own thread reads and posts from inside the terminal, signed with your wallet — you never leave to say something.

Your keys stay on your machine

The private key never leaves this computer. The vault is encrypted with the operating system's own key store, behind a password you choose, and signing out leaves it exactly where it is. You can read the whole venue without signing in at all. Updates arrive on their own and are checked against a signature before they are allowed to run — one that fails the check is discarded, not installed.
