# No overnight margin without GO

Do not let an agent leave leveraged or margin exposure open overnight (or across a session you will not watch) unless you explicitly GO that risk — default is flatten or reduce before sleep. Pair with empty-sleeve-overnight, kill-switch-before-travel, session-time-box, cap-daily-loss-before-session, confirm-cancel-in-broker-not-chat. Agent Lane does not place trades, hold wallets, or invent broker UI.

## Answer first

Before you sleep, travel, or leave a live agent session unwatched: check open leveraged or margin exposure in the official venue UI. Unless you explicitly wrote GO for overnight margin on that named plan, flatten or reduce. Confirm cancel or flat in the broker, not chat. Then empty or park the sleeve.

## Margin and leverage in plain terms

- **Margin / leverage** — borrowed buying power or amplified exposure so a move against you can cost more than the cash you put up for that position.
- **Overnight margin** — that amplified exposure left open while you sleep, travel, or across idle you will not watch.
- **GO** — written deliberate exception on the named plan (size, watch plan, kills). Hope is not a GO.
- **Default** — flatten or reduce before sleep.

## Why unwatched overnight margin is the failure mode

- **Review only works while someone watches** — [never-skip-review-before-place.md](./never-skip-review-before-place.md).
- **Cash empty ≠ position flat** — [empty-sleeve-overnight.md](./empty-sleeve-overnight.md).
- **Chat flat is not settlement** — [confirm-cancel-in-broker-not-chat.md](./confirm-cancel-in-broker-not-chat.md).
- **“I’ll watch from my phone” without GO** — [kill-switch-before-travel.md](./kill-switch-before-travel.md), [session-time-box.md](./session-time-box.md).

## What it means

1. Default flatten or reduce before sleep / unwatched idle — unless written GO.
2. Venue UI for open leveraged risk — not chat.
3. Confirm cancel/flat in broker — [confirm-cancel-in-broker-not-chat.md](./confirm-cancel-in-broker-not-chat.md).
4. Pair cash park — [empty-sleeve-overnight.md](./empty-sleeve-overnight.md); clock — [session-time-box.md](./session-time-box.md); loss stop — [cap-daily-loss-before-session.md](./cap-daily-loss-before-session.md).
5. Travel/offline — [kill-switch-before-travel.md](./kill-switch-before-travel.md).
6. Any GO → [journal-every-override.md](./journal-every-override.md).

## Different from empty sleeve / kill switch / time-box

- [empty-sleeve-overnight.md](./empty-sleeve-overnight.md) — park spendable cash.
- [kill-switch-before-travel.md](./kill-switch-before-travel.md) — travel/offline composite.
- [session-time-box.md](./session-time-box.md) — clock for the live window.
- This page — overnight leveraged / margin exposure rule (default flatten unless GO).

Use the stack.

## Shield stack

1. [name-the-strategy-before-connect.md](./name-the-strategy-before-connect.md) — overnight rule on the plan (default: no GO).
2. [cap-daily-loss-before-session.md](./cap-daily-loss-before-session.md).
3. [session-time-box.md](./session-time-box.md).
4. [empty-sleeve-overnight.md](./empty-sleeve-overnight.md).
5. No overnight margin without GO (this page).
6. [confirm-cancel-in-broker-not-chat.md](./confirm-cancel-in-broker-not-chat.md).
7. [kill-switch-before-travel.md](./kill-switch-before-travel.md).

## How to run no overnight margin without GO

1. Define margin risk in plain terms for this sleeve — no invented UI.
2. Default flatten/reduce before sleep unless written GO — [name-the-strategy-before-connect.md](./name-the-strategy-before-connect.md).
3. Confirm opens and flat in venue UI — [confirm-fills-in-broker-not-chat.md](./confirm-fills-in-broker-not-chat.md), [confirm-cancel-in-broker-not-chat.md](./confirm-cancel-in-broker-not-chat.md).
4. Pair empty sleeve, time-box, loss cap — [empty-sleeve-overnight.md](./empty-sleeve-overnight.md), [session-time-box.md](./session-time-box.md), [cap-daily-loss-before-session.md](./cap-daily-loss-before-session.md).
5. Travel/offline → [kill-switch-before-travel.md](./kill-switch-before-travel.md).
6. Journal any GO — [journal-every-override.md](./journal-every-override.md); close: [log-session-end-checklist.md](./log-session-end-checklist.md).

## Practical checklist

- Overnight rule written (default: no GO).
- Margin defined in plain terms for this sleeve.
- Venue UI checked for leveraged opens — not chat.
- Flat/reduced confirmed in broker before walk-away (unless GO).
- Sleeve emptied/parked; time-box and loss cap honored.
- Travel: kill switch; any GO journaled.
- Official paths only — no invented broker UI.

## FAQ

**What does no overnight margin without GO mean?**
Do not leave leveraged or margin exposure open overnight or across unwatched idle unless you explicitly write GO. Default is flatten or reduce before sleep. Pair with empty-sleeve-overnight, kill-switch-before-travel, session-time-box, cap-daily-loss-before-session, confirm-cancel-in-broker-not-chat.

**What is margin or leverage in plain terms?**
Borrowed buying power or amplified exposure so a move against you can cost more than the cash you put up. Overnight margin = that exposure left open while you sleep or across idle you will not watch.

**Do I invent a broker overnight-margin UI?**
No. Official venue screens and your written GO/flatten rule. Agent Lane does not invent UI.

**Does this replace empty sleeve or kill switch?**
No. Cash park, travel kill, clock, loss stop, and overnight margin rule are different brakes. You need the stack.
