Confirm cancel in the broker, not chat

When an agent says it cancelled an order or closed a position, verify the cancel or flat state in the broker or wallet UI yourself — chat is not the source of truth. Pair it with confirm fills in the broker, not chat, never skip review before place, log session end checklist, and journal every override.

Answer first

After an agent claims a cancel or close — and before you treat the book as flat, place again, or end the session — open the broker or wallet UI you control and confirm order cancel, residual, or position flat there. Do not treat the chat transcript or an agent “cancelled / flat” claim as settlement. Agents summarize; venues settle. Agent Lane publishes the checklist. We do not place trades, hold wallets, invent broker UI, or run your agents.

What this page is

A short operator guide for the cancel/flat venue-truth step on the shield — sibling to confirm fills, aimed at cancel and close claims instead of fill claims. Pair it with confirm fills in the broker, not chat, never skip review before place, log session end checklist, journal every override, receipt log after the session, empty the sleeve overnight, and revoke before you debug.

We are a publisher, not a trading desk. Product screens change; confirm labels on the official page. We do not invent a broker cancel screen or API for readers.

Why trusting chat as the cancel/flat record is the failure mode

• Still working. Chat can say “cancelled” while the order is still open or only partially dead — see confirm fills in the broker, not chat.
• Residual risk. A close claim can leave a leftover size or a hedge the summary skipped — count opens with max open positions per sleeve.
• Hallucinated flat. Models invent clean cancels when a connector timed out, a reject landed, or the tool soft-pedaled an error.
• Wrong close → wrong next place. Placing again or logging session-end on a chat flat leaves live risk under a closed checklist — log session end checklist, journal every override.

What “confirm cancel in the broker, not chat” means

• Venue UI first. Orders, activity, positions, or balance views the official product exposes — not the chat scrollback.
• Cancel state. Still open, cancelled, rejected, or residual — quantity and symbol matched to the claim.
• Flat state. Position open vs flat for that name or sleeve before you treat risk as gone.
• Then the log. Write what the venue showed into receipt log, session-end checklist, or override journal.
• Gate stays on. Deliberate cancel/close you approve still goes through review — never skip review before place.

Where it sits in the shield stack

1. Never skip review before place — human gate on place and on deliberate cancel/close you approve.
2. Confirm fills in the broker, not chat — venue truth after a place.
3. Confirm cancel in the broker, not chat — venue truth after a cancel or close claim.
4. Log session end checklist — write cancel/flat (or leftover open) before you walk away.
5. Journal every override — if a human forced a cancel/close or skipped a gate, write why and what the venue showed.
6. Revoke before you debug — kill-and-isolate when venue and chat disagree badly.

Healthy run: gate → place → confirm fills → (if cancel/close) confirm cancel → log what the venue showed. Skip the cancel check and you can place again on a hallucinated flat.

How to confirm cancel in the broker

1. Keep review on for cancel/close intents. Symbol, size, and venue visible before you approve a cancel or close. No standing “just cancel it” — never skip review.
2. When the agent claims cancel or flat, open the venue UI. Use the official broker or wallet UI for that sleeve — orders, activity, positions. Do not invent a product screen; use what you already use for that account.
3. Confirm order state. Still open vs cancelled vs rejected vs residual quantity; symbol matched to the claim.
4. Confirm position state. Open vs flat for that name or sleeve. Count concurrent opens against your max open positions if you run that brake.
5. Write what the venue showed. Copy into receipt log, session-end checklist, and override journal when a human overrode. Overnight still follows empty the sleeve overnight.
6. Only then place again or end the session. Chat/venue mismatch or a leftover open you did not expect: revoke before you debug — disconnect → lock → empty sleeve → revoke or rotate — then dig. Prefer paper before live until the pipe proves clean.

Practical checklist

• Venue before chat. Broker/wallet UI wins on cancel and flat; agent summaries do not settle.
• Residuals count. A partial cancel is not “done” — confirm rest or leftover size in the UI.
• Flat before next place. Never open a new ticket on a chat-reported flat.
• Log from venue fields. Session-end and override notes copy what the UI showed.
• Shared-box pass. Confirm in the same profile that owns the sleeve — separate browser profile, shared-box.

FAQ

What does confirm cancel in the broker, not chat mean?

It means: when an agent says it cancelled an order or closed a position — and before you treat the book as flat, place again, or end the session — open the broker or wallet UI you control and confirm cancel, rejection, still-open, or flat state there. Chat claims are not settlement.

Why is trusting chat as the cancel/flat record the failure mode?

Agents summarize; they do not settle. A chat line can claim cancelled while the order is still working, report flat while a residual sits open, or invent a close after a reject. If you place again or log the session closed on that summary, risk stays live under a wrong picture.

How is this different from confirm fills in the broker?

Confirm fills is the venue-truth step after a place — what filled, partial, or rejected. Confirm cancel is the venue-truth step after a cancel or close claim — is the order gone, is the position flat. Both treat the broker or wallet UI as source of truth over chat. Use both.

How does this pair with never-skip-review, log-session-end, and journal-every-override?

Never skip review is the gate before a place or a deliberate cancel/close you approve. Confirm cancel is the venue check after the agent claims cancel or flat. Log session end and journal every override record what the venue showed — including leftover opens — so the next session inherits reality.

What should I confirm in the broker or wallet UI?

Order still open vs cancelled vs rejected; residual quantity if any; position open vs flat for that symbol or sleeve; fill or close fields if the UI shows them; and that chat’s claim matches the venue. Match to what you approved if you gated the cancel/close.

Do I invent a broker cancel screen?

No. Use the official broker or wallet UI you already use for that account — orders, activity, positions, or balance views the product exposes. Agent Lane does not invent product menus, click-paths, or API claims for cancels.

Where do I apply this next?

After place: confirm fills in the broker, not chat. Gate: never skip review before place. Session close: log session end checklist. Override: journal every override. Cash/idle: empty the sleeve overnight and revoke connectors when idle. Agent Lane publishes the checklist; we do not place trades or invent broker UI.
