Reject duplicate place same thesis

Reject a second (or nth) place that is the same thesis / same idea while a working order or open risk for that idea already exists — one risk unit, one live ticket path; no accidental double-submit from chat retries or agent loops. Pair it with one risk unit per idea, no averaging down without a new thesis, max open positions per sleeve, no chase after partial fill, never skip review before place, write invalidation before entry, and confirm fills in the broker, not chat.

Answer first

Before a live place: in the broker UI (not chat), check whether this thesis already has a working order or open risk. If yes, reject the duplicate place. One idea → one live ticket path on top of one risk unit. Chat retries and agent loops are not a second GO. 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 same-thesis duplicate-place reject on the shield — so the agent cannot stack a second ticket for an idea that is already live. Pair it with one risk unit per idea, no averaging down without a new thesis, max open positions per sleeve, no chase after partial fill, never skip review before place, write invalidation before entry, confirm fills in the broker, not chat, journal every override, and the shared-box checklist.

We are a publisher, not a trading desk. Product screens change; read orders and positions on the official page. We do not invent duplicate-order dashboards or Agentic click-paths. You reject the duplicate at review after confirming the live path in the broker.

Reject duplicate place same thesis in plain terms

• Same thesis, already live — working order or open risk for that idea exists in the broker UI.
• Reject the second place — one risk unit, one live ticket path; no “place again” from chat.
• Broker truth, not chat — confirm fills in the broker, not chat before any re-place.
• Not a deliberate add — intentional add-size needs a new written thesis, not a duplicate submit.
• Gate at review — never skip review before place; reject if the live path already exists.

Why double-submit from chat retries is the failure mode

• “Did it place?” retry. Chat lag → human or agent re-submits the same thesis — confirm fills in the broker.
• Agent loops. A stuck run places twice for one idea — quietly doubles the risk unit — one risk unit per idea.
• Partial + new full place. Remainder chase plus a fresh full ticket — no chase after partial fill.
• Add without a new thesis. Stacking size under the same idea label — no averaging down without a new thesis.

Where it sits in the shield stack

1. One risk unit per idea — max loss for this thesis in sleeve terms.
2. Write invalidation before entry — kill line before the first place.
3. Confirm fills in the broker, not chat — live path truth before any re-place.
4. Reject duplicate place same thesis — no second place while working/open for that idea.
5. Never skip review before place — human gate enforces the reject.
6. No averaging down without a new thesis — deliberate add needs a fresh thesis, not a duplicate.
7. No chase after partial fill — remainder rules, not a second full place.
8. Max open positions per sleeve — sleeve-wide count cap beside same-thesis discipline.
9. Journal every override — write every double-submit that slipped through.

Healthy flow: risk unit → invalidation → review → place once → confirm in broker → reject same-thesis duplicates. Skip the reject and one idea becomes two live paths.

How to run reject duplicate place same thesis

1. Name the idea and risk unit. Tie to one risk unit; write invalidation before entry. No invented UI.
2. Check broker for live path. Working order or open risk for this thesis? Use the broker UI — confirm fills in the broker, not chat.
3. Reject duplicate place. If live path exists, reject — one risk unit, one live ticket path. Same review step — never skip review.
4. Partial remainder ≠ new full place. Follow no chase after partial fill; do not launch a second full ticket for the same idea.
5. Deliberate add needs a new thesis. No averaging down without a new thesis; scale changes need write GO before scale-up.
6. Journal overrides; respect sleeve caps. Journal every override; max open positions per sleeve; misfire: revoke before you debug.

Practical checklist

• Thesis named and risk unit set before place.
• Broker UI checked for working order / open risk on that thesis.
• Reject same-thesis second place while live path exists.
• Chat retry is not a GO — confirm in broker first.
• Partial remainder follows no-chase rules, not a duplicate full place.
• Deliberate add needs a new written thesis + review.
• Overrides journaled if anyone double-submitted.
• No invented UI. Official order/position screens and your notes; you enforce.
• Shared-box pass. Who can approve a duplicate same-thesis place on a shared computer — see shared-box.

FAQ

What does reject duplicate place same thesis mean?

It means: while a working order or open risk for an idea already exists, reject a second (or nth) place that is the same thesis — one risk unit, one live ticket path. Stops accidental double-submit from chat retries or agent loops. Pair with one risk unit per idea, no averaging down without a new thesis, max open positions per sleeve, no chase after partial fill, never skip review before place, write invalidation before entry, and confirm fills in the broker, not chat.

How is this different from one risk unit per idea?

One risk unit caps max loss in sleeve terms. Reject duplicate place is the live-ticket gate: do not open a second place path for the same idea while the first is still working or open. You need both.

How is this different from no averaging down without a new thesis?

No averaging down is the deliberate add-size gate when price is against you. Reject duplicate place is about accidental double-submit of the same thesis (retry, loop) while risk or a working order already exists.

How is this different from no chase after partial fill?

No chase after partial is about finishing a remainder with worse prices. Reject duplicate place is about not launching a second full place for the same idea while the first ticket is still live.

Why is double-submit from chat retries the failure mode?

Agents and humans re-ask “did it place?” and retry. Without a same-thesis duplicate reject, one idea becomes two working orders or stacked open risk — quietly multiplying the risk unit. Confirm fills in the broker UI before any re-place.

Does this replace never skip review or max open positions?

No. Never skip review is the human ticket gate. Max open positions caps how many names a sleeve may hold. Write invalidation is the pre-entry kill line. This page is the same-thesis duplicate-place reject. You need the stack.

Where do I apply this next?

At review before place: check broker UI for working orders and open risk tied to this thesis. If one already exists, reject the duplicate place. Confirm fills in the broker, not chat. Agent Lane publishes the checklist; we do not place trades or invent broker UI.
