# Cap daily loss before session

Before an agent money session starts, set a hard daily (or session) loss cap and stop rules — so a losing streak cannot keep placing after the budget for the day is gone. Pair with fund-session-ceiling, session-time-box, name-the-strategy-before-connect, never-skip-review-before-place, and two-person-rule-for-large-places. Agent Lane does not place trades, hold wallets, or invent broker UI.

## Answer first

Do not start a live agent money session until a hard daily or session loss limit and stop rules exist. A funded sleeve and an open clock still let a streak place until the cash is gone. The loss cap ends place/pay/sign when the budget is spent.

## Why no loss stop is the failure mode

- **Ceiling + clock without a loss stop** — [fund-session-ceiling.md](./fund-session-ceiling.md), [session-time-box.md](./session-time-box.md).
- **Streak chasing burns the day** — [never-skip-review-before-place.md](./never-skip-review-before-place.md).
- **Size caps ≠ cumulative loss** — [agent-spend-caps.md](./agent-spend-caps.md).

## What it means

1. Loss number written first — daily or session max (dollars or %).
2. What counts — realized fills + fees; mark optional but explicit.
3. Stop rules — disable connectors, park sleeve, log; no “one more try.”
4. Pair with [fund-session-ceiling.md](./fund-session-ceiling.md) and [session-time-box.md](./session-time-box.md).
5. Pair with [name-the-strategy-before-connect.md](./name-the-strategy-before-connect.md), [never-skip-review-before-place.md](./never-skip-review-before-place.md), [two-person-rule-for-large-places.md](./two-person-rule-for-large-places.md).

## Shield stack

1. [name-the-strategy-before-connect.md](./name-the-strategy-before-connect.md) — plan (loss cap is a kill condition).
2. Cap daily loss before session (this page) — loss budget + stops.
3. [fund-session-ceiling.md](./fund-session-ceiling.md).
4. [session-time-box.md](./session-time-box.md).
5. [never-skip-review-before-place.md](./never-skip-review-before-place.md) + [two-person-rule-for-large-places.md](./two-person-rule-for-large-places.md).
6. [log-session-end-checklist.md](./log-session-end-checklist.md).

## How to cap daily loss before session

1. Write the loss number first — [agent-spend-caps.md](./agent-spend-caps.md).
2. Define what counts — confirm [confirm-fills-in-broker-not-chat.md](./confirm-fills-in-broker-not-chat.md).
3. Write stop rules — [empty-sleeve-overnight.md](./empty-sleeve-overnight.md) habit on hit.
4. Pair with ceiling and time-box — [fund-session-ceiling.md](./fund-session-ceiling.md), [session-time-box.md](./session-time-box.md).
5. Name strategy; keep review on — [name-the-strategy-before-connect.md](./name-the-strategy-before-connect.md), [never-skip-review-before-place.md](./never-skip-review-before-place.md), [two-person-rule-for-large-places.md](./two-person-rule-for-large-places.md).
6. Track from broker UI; hard-stop on hit — [log-session-end-checklist.md](./log-session-end-checklist.md); travel: [kill-switch-before-travel.md](./kill-switch-before-travel.md).

## Practical checklist

- Loss number written before connect.
- What counts written (realized + fees; mark explicit if used).
- Stop rules written — no “one more try.”
- Ceiling funded only; time-box set.
- Strategy named; review on.
- Track from broker UI, not chat.
- Official paths only — no invented broker UI.

## FAQ

**What does cap daily loss before session mean?**
Write a hard daily/session loss limit and stop rules before the live window — so a streak cannot keep placing after the budget is gone. Pair with fund-ceiling, time-box, name-strategy, never-skip-review, two-person-rule.

**Do I invent a broker daily-loss UI?**
No. Official venue flows and your notes only. Agent Lane does not invent UI.

**Does this replace fund-ceiling or time-box?**
No. Cash, clock, and loss budget are three different brakes. You need the stack.
