One order per idea until fill

Keep at most one working order per thesis until it fills, cancels, or you write a replace GO — no ladder spam / multi-ticket stacking that quietly multiplies the same idea. Pair it with reject duplicate place same thesis, one risk unit per idea, no chase after partial fill, max open positions per sleeve, no scale-in without GO, and never skip review before place.

Answer first

Before a live place: in the broker UI (not chat), check whether this thesis already has a working order. If yes, do not place another until that order fills, cancels, or you write an explicit replace GO (cancel → confirm in broker → then replace). One idea → one working ticket. Ladder rungs and “stack another limit” are not free size. 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 standing one-working-order rule on the shield — so each thesis keeps at most one live working ticket until fill, cancel, or replace GO. Pair it with reject duplicate place same thesis, one risk unit per idea, no chase after partial fill, max open positions per sleeve, no scale-in without GO, never skip review before place, one cancel, one confirm, confirm fills in the broker, not chat, and the shared-box checklist.

We are a publisher, not a trading desk. Product screens change; read working orders on the official page. We do not invent ladder dashboards or Agentic click-paths. You enforce one working order per thesis at review.

One order per idea until fill in plain terms

• One working order per thesis — until fill, cancel, or a written replace GO.
• No ladder spam — multiple limits for the same idea quietly multiply exposure.
• Replace is cancel-then-place — confirm cancel in the broker, then place under the GO.
• Broker truth, not chat — confirm fills in the broker, not chat.
• Gate at review — never skip review before place.

Why ladder spam / multi-ticket stacking is the failure mode

• Ladder “just in case.” Several limits for one thesis → several fills if price sweeps — quietly multiplies the risk unit — one risk unit per idea.
• Stack beside a working ticket. Agent places again while the first is still live — same idea, two paths — reject duplicate place same thesis.
• Partial + new full working order. Remainder chase plus a fresh ticket — no chase after partial fill.
• Silent “replace” without cancel confirm. Second ticket lives beside the first — one cancel, one confirm, confirm cancel in the broker, not chat.

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 — working/fill truth before any re-place.
4. One order per idea until fill — at most one working ticket until fill, cancel, or replace GO.
5. Reject duplicate place same thesis — reject second same-thesis place while working/open risk exists.
6. Never skip review before place — human gate enforces the one-order rule.
7. No chase after partial fill — remainder rules, not a second full working path.
8. No scale-in without GO — deliberate add-size needs a written GO.
9. Max open positions per sleeve — sleeve-wide count cap beside per-thesis order discipline.
10. Journal every override — write every stacked working order that slipped through.

Healthy flow: risk unit → invalidation → review → one working order → wait for fill/cancel or replace GO with confirm cancel. Skip the one-order rule and one idea becomes a ladder of live tickets.

How to run one order per idea until fill

1. Name the thesis and risk unit. Tie to one risk unit; write invalidation before entry. No invented UI.
2. Check broker for a working order on this thesis. Official screens — confirm fills in the broker, not chat.
3. Keep at most one working order. If one exists, do not place another until fill, cancel, or replace GO. Same review step — never skip review; pair with reject duplicate place same thesis.
4. Replace only with written GO + confirm cancel. Cancel → one cancel, one confirm / confirm cancel in the broker → then place the replacement.
5. Partial remainder ≠ new full working stack. Follow no chase after partial fill; scale-in needs no scale-in without GO.
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 a working order on that thesis.
• At most one working order until fill, cancel, or replace GO.
• No ladder spam / multi-ticket stacking for the same idea.
• Replace = cancel confirm → place under a written GO.
• Partial remainder follows no-chase rules, not a second full working path.
• Scale-in / add needs its own GO — not another silent working ticket.
• Overrides journaled if anyone stacked a second working order.
• No invented UI. Official order screens and your notes; you enforce.
• Shared-box pass. Who can approve a second working order for the same thesis on a shared computer — see shared-box.

FAQ

What does one order per idea until fill mean?

It means: keep at most one working order per thesis until that order fills, cancels, or you write an explicit replace GO — no ladder spam or multi-ticket stacking that quietly multiplies the same idea. Pair with reject duplicate place same thesis, one risk unit per idea, no chase after partial fill, max open positions per sleeve, no scale-in without GO, and never skip review before place.

How is this different from reject duplicate place same thesis?

Reject duplicate place same thesis is the review gate that rejects a second same-thesis place while working or open risk already exists — often from chat retries or agent loops. One order per idea until fill is the standing operating rule: at most one working ticket for that thesis until fill, cancel, or a written replace GO. Overlapping, but this page is the ongoing one-working-order discipline, including against deliberate ladder spam.

How is this different from one risk unit per idea?

One risk unit caps max loss in sleeve terms. One order per idea until fill caps how many simultaneous working tickets may represent that thesis. You need both.

How is this different from no chase after partial fill?

No chase after partial is about finishing a remainder with worse prices. This page is about not stacking multiple working tickets for the same idea before any of them fills or cancels.

How is this different from no scale-in without GO or max open positions?

No scale-in without GO is the add-size gate on an open winner. Max open positions caps how many names a sleeve may hold. This page is specifically: one working order per thesis until fill, cancel, or replace GO.

What counts as a replace GO?

A written GO that cancels or replaces the existing working order and states the new size, limit, and invalidation — not a silent second ticket beside the first. Confirm cancel in the broker UI before the replacement place.

Do I invent a one-order broker UI?

No. Use official venue order screens you already control, plus your written one-working-order rule. Agent Lane does not invent ladder dashboards, OCO menus, or Agentic click-paths.

Where do I apply this next?

At review before place: check the broker UI for any working order tied to this thesis. If one exists, do not place another until it fills, cancels, or you write a replace GO and confirm cancel. Agent Lane publishes the checklist; we do not place trades or invent broker UI.
