One venue, one agent session

Keep one agent session pointed at one trading venue (or one broker account) so fills, cancels, and kill-switches stay unambiguous — do not let the same chat juggle two brokers or mix paper + live without a hard wall. Pair it with separate browser profile for the agent, one strategy, one sleeve, separate funding from trading wallet, never skip review before place, and confirm fills in the broker, not chat.

Answer first

Before you connect or place: name the single venue (broker/exchange/account) and mode (paper or live) this agent session may touch. Do not attach a second live broker to the same chat. Do not promote a paper session to live without a new named wall. Confirm fills and cancels in that venue’s official UI — not chat. 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 session/venue wall on the shield — one venue, one agent session — so fills, cancels, and kill-switches map to one rail. Pair it with separate browser profile for the agent, one strategy, one sleeve, separate funding from trading wallet, never skip review before place, confirm fills in the broker, not chat, paper before live, one connector at a time, and the shared-box checklist.

We are a publisher, not a trading desk. Product screens change; read accounts and fills on the official page. We do not invent multi-venue dashboards or Agentic menus. You name the venue and keep the session wall.

Venue and session in plain terms

• Venue — the broker, exchange, or wallet rail this session may place on (one account you named).
• Agent session — this chat / run with live or paper connectors attached.
• Hard wall — paper and live are separate sessions (and preferably separate connectors/profiles); two live brokers do not share one chat.
• Not the wall — “I’ll remember which is which,” juggling two brokers in one thread, or reusing a paper chat for live places.

Why juggling venues in one chat is the failure mode

• Fills blur across brokers. Chat says “filled” — which venue? Confirm in the broker UI, not chat.
• Cancels hit the wrong rail. A kill meant for A “looks done” while B still has working orders — confirm cancel in the broker, not chat.
• Paper habits go live. Reusing a paper session for live places skips the wall — paper before live, never skip review.
• Kill-switch covers the wrong surface. Revoking one connector while another stays live in the same chat is not a clean stop — revoke connectors when idle, kill switch before travel.

Where it sits in the shield stack

1. Name the strategy before connect — written plan including which venue/mode this session may use.
2. Separate browser profile for the agent — personal cookies/SSO off the agent path.
3. One strategy, one sleeve — cash and stops isolated per named plan.
4. Separate funding from trading wallet — cold capital off the hot path.
5. One venue, one agent session — this chat maps to one venue/mode; hard wall paper vs live and broker vs broker.
6. Never skip review before place — human gate on that venue only.
7. Confirm fills in the broker, not chat — venue UI is truth for that rail.

Healthy flow: name plan + venue → browser wall → sleeve + funding split → one session one venue → review → confirm in that venue → kill/revoke that rail only. Skip the venue wall and review/confirm alone will not stop a cancel or fill attributed to the wrong broker.

How to run one venue, one agent session

1. Name the venue for this session. Broker/exchange/account + paper or live — name the strategy before connect. No invented UI.
2. Open one session pointed at that venue. No second live broker in the same chat. Prefer separate browser profile; one connector at a time.
3. Hard-wall paper from live. Separate sessions (and preferably connectors). Prove dry first — paper before live, dry run before first live place.
4. Keep review and fills on that venue only. Never skip review. Confirm fills/cancels in the broker / cancel UI — not chat.
5. Kill-switch maps to one rail. Revoke when idle; travel: kill switch before travel; close: log session end checklist.
6. Journal if you switch venues. Ending one venue session and starting another is a new run — journal every override; do not juggle mid-chat.

Practical checklist

• Venue + mode written — one broker/account and paper or live on the named plan.
• One session → one venue — no second live broker in the same chat.
• Paper and live hard-walled — separate sessions/connectors; no promote-in-place.
• Browser wall on — agent path not personal banking profile.
• Sleeve + funding split — one strategy one sleeve; cold capital off hot path.
• Review on; fills/cancels in that venue UI — not chat.
• Kill/revoke maps to this rail — idle and travel covered.
• Venue switch = new session — journaled; not mid-chat juggle.
• No invented UI. Official screens and your notes; you enforce.
• Shared-box pass. Who can attach a second broker on a shared computer — see shared-box.

Brokerage path: Shield brokerage spend. On-chain pay: Shield crypto spend.

FAQ

What does one venue, one agent session mean?

It means: keep one agent chat or session pointed at one trading venue or one broker account so fills, cancels, and kill-switches stay unambiguous. Do not let the same chat juggle two brokers, or mix paper and live without a hard wall. Pair with separate browser profile for the agent, one strategy, one sleeve, separate funding from trading wallet, never skip review before place, and confirm fills in the broker, not chat.

What is a “venue” in plain terms?

The broker, exchange, or wallet rail this session is allowed to place on — one account (or clearly labeled paper vs live path) that you named before connect. Not a second broker in the same chat, and not paper and live mixed without a hard wall.

Do I invent a broker multi-venue UI?

No. Write the venue on the named plan and enforce it for this session. Use official venue account screens. Agent Lane does not invent broker dashboards, multi-account menus, or Agentic click-paths.

Why is juggling two brokers in one chat the failure mode?

Fills, cancels, and kill-switches blur. A cancel meant for venue A can be “confirmed” against venue B in chat. Paper and live mixed without a wall lets a live place ride a paper habit. Review and confirm-fills lose a single source of truth.

Does this replace one strategy one sleeve or separate browser profile?

No. One strategy, one sleeve isolates cash and stops per named plan. Separate browser profile keeps personal cookies off the agent path. One venue, one agent session is the session/venue wall so that chat and kill-switch map to one rail. You need the stack.

How do I hard-wall paper vs live?

Separate sessions (and preferably separate connectors or profiles) for paper and live. Do not reuse a paper chat for live places. Confirm fills and cancels in the official venue UI for the mode you named — not chat. Pair with paper before live and confirm fills in the broker, not chat.

Where do I apply this next?

Browser wall: separate browser profile for the agent. Plan and cash: one strategy, one sleeve; separate funding from trading wallet. Gate: never skip review before place. Truth: confirm fills in the broker, not chat. Agent Lane publishes the checklist; we do not place trades or invent broker UI.
