Closing and exits
The P&L on the line is what CLOSE pays. Close by hand, or set take-profit, stop-loss or a trail and walk away.
CLOSE and Reduce
CLOSE sells your whole position back to the Window's book in one tap, at what the position shows — or a little below it, within the close tolerance in Trade settings. Reduce sells 25, 50 or 75 %. If the book has moved further than the tolerance, the sale asks again at the new price rather than fill worse. "Closing…" shows the instant the sale is signed. A Window that has locked can't be sold into; it settles.
Take-profit, stop-loss, trail
- Take-profit sells when what CLOSE pays rises to your target.
- Stop-loss sells when it falls to your floor.
- Trail arms once the price is the trailing distance past break-even. Its stop only moves your way, and it closes when the price comes back to it.
On a wallet position these run in your browser while Mitoshi is open, and a trail needs one-tap on to sell without a prompt. A Boost closes from its own row with your passkey; trail and TP/SL don't run on it.
With the app closed
On a Trading Balance position, one passkey confirmation grants Mitoshi's keeper an EXIT permission. When your exit triggers, the keeper sells whether your tab is open or not.
You grant a sell-only permission once; the keeper decides when; the vault decides the lowest price.

Trading Balance
A vault you own on Tempo that holds money and positions for you. Deposits and withdrawals are yours; proceeds of every sale land back in it.
Only the owner withdraws. Intake is never fee-sponsored.
Live on Moderato since 2026-10-09: a stop-loss sold by the keeper 20.6 s after it triggered, with the tab closed. An exit fills only against a bid that is there.

- The floor. Every keeper sale's limit must be at or above the Window's fair value at a signed RedStone spot, less the wider of 15 % of it or 10¢ — the allowance the app grants. The contract refuses anything wider than 20 % or 15¢, and a sale under the floor reverts.
- No bid, no sale. If no bid meets the floor, the keeper waits and tries again until the Window locks, rather than sell lower. The terminal shows its last reason ("Keeper waiting: …").
- Where it applies. The floor comes from the fair-value guard, which has a volatility and a signed spot for every series, crypto and stocks. It refuses to price a Window it has no model for, and with no floor the keeper cannot sell.
- The house's side. The house keeps its exit side quoted until about 30 seconds before a Window locks.
Every EXIT grant lasts 30 days and is listed in Account & keys; Stop revokes it on chain.

On 9 October a CI run armed a stop-loss on SOL from the terminal, closed the tab, and the keeper sold it 20.6 s after it triggered: 0xa5dd…36aa. An exit is a sale into a real book: it fills only against a bid that is there.
The Trading Balance
A vault you own on Tempo. A capped key taps from it, a keeper runs your exits from it, a strategy trades in it — and only you withdraw.
Range and Moonshot
Call a band the close lands in, or a level it finishes past — on any live Window, coin or stock. The house reserve sets your payout aside up front.
