Confirm buying power before place

Before the agent places, confirm buying power / available cash in the broker (not chat math) so you don’t submit into a reject, partial, or margin surprise. Pair it with never skip review before place, confirm fills in the broker, not chat, read-only quote before trade connector, dry run before first live place, and size from sleeve not from hope.

Answer first

Before a live place: read buying power or available cash in the official broker UI — not from chat arithmetic, agent memory, or a stale sleeve note. If the venue cannot fund the ticket cleanly, do not submit. Size still comes from written sleeve rules; the human still runs review before place. 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 pre-place cash/BP gate on the shield — confirm buying power before place — so a ticket sized in chat does not hit a reject, partial, or unexpected margin. Pair it with never skip review before place, confirm fills in the broker, not chat, read-only quote before trade connector, dry run before first live place, size from sleeve not from hope, fund the session ceiling, and the shared-box checklist.

We are a publisher, not a trading desk. Product screens change; read balances on the official page. We do not invent buying-power dashboards or Agentic menus. You read the venue screen and enforce the gate at review.

Confirm buying power before place in plain terms

• Venue truth first — open the official buying power / available cash screen for the account or sleeve in play.
• Not chat math — agent summaries, memory, and “we still have ~$X” are not the source of truth.
• Ticket must fit — size from sleeve rules must fit what the venue can fund without hope or surprise leverage.
• Gate at review — enforce at never skip review before place; reject if BP cannot cover.
• Re-check after change — after fills, cancels, transfers, or idle; confirm fills afterward in the broker, not chat.

Why chat math is the failure mode

• Stale cash. Chat lags fills, cancels, and unsettled funds — confirm fills in the broker, not chat.
• Rejects and partials. Submitting above true BP burns the session on bounced tickets and half-fills you did not intend — never skip review before place.
• Margin surprise. “Available” in chat may ignore margin haircuts or open-order holds — no overnight margin without GO, fund the session ceiling.
• Hope sizing. Conviction-based size that “should fit” without reading BP is sleeve hope — size from sleeve not from hope.

Where it sits in the shield stack

1. Read-only quote before trade connector — prove prices before place rights.
2. Dry run before first live place — prove the pipe without live cash.
3. Size from sleeve not from hope — written ticket size rules.
4. Confirm buying power before place — venue cash/BP covers that ticket.
5. Never skip review before place — human gate enforces the check.
6. Confirm fills in the broker, not chat — after-the-fact venue truth.
7. Fund the session ceiling — only fund what the session may spend.

Healthy flow: quote → dry run → size from sleeve → read BP in broker → review → place → confirm fill. Skip the BP gate and a well-sized thesis still submits into a bounce or surprise leverage.

How to run confirm buying power before place

1. Keep review before place on. Pair with never skip review before place. The human gate is where BP is checked — no invented UI.
2. Open official buying power / available cash. Read the venue label for the account/sleeve in play. After prior activity: confirm fills and confirm cancels first.
3. Compare ticket to sleeve size rules. Size from sleeve not hope; one idea one risk unit; large tickets may need two-person rule.
4. Reject if cash/BP cannot cover. Resize within sleeve rules, re-fund only to the session ceiling after rotate before raise, or skip. Do not “hope it goes through.”
5. Place only after human review; confirm afterward. Then confirm fills in the broker. First live after novelty: dry run; quote ladder: read-only quote.
6. Re-check after fills, cancels, transfers, or idle; journal overrides. Journal every override; if something misfired: revoke before you debug.

Practical checklist

• Official BP/cash screen open before every live place.
• Chat math is not BP.
• Ticket fits sleeve rules and venue cash/BP.
• Reject / resize / skip if it does not fit — no “submit and see.”
• Review before place still on — human enforces the gate.
• Re-check after fill, cancel, transfer, or idle gap.
• Confirm fills afterward in the broker UI.
• Dry run done before first live with a new connector/strategy.
• Overrides journaled if anyone places without reading BP.
• No invented UI. Official screens and your notes; you enforce.
• Shared-box pass. Who can approve a place without reading BP on a shared computer — see shared-box.

FAQ

What does confirm buying power before place mean?

It means: before the agent submits a live place, read buying power or available cash in the official broker (or wallet) UI — not from chat arithmetic, agent memory, or a stale sleeve note — so you do not submit into a reject, partial fill, or margin surprise. Pair with never skip review before place, confirm fills in the broker, not chat, read-only quote before trade connector, dry run before first live place, and size from sleeve not from hope.

Why is chat math the failure mode?

Chat can lag, invent, or reuse yesterday’s cash. Buying power also changes with open orders, unsettled funds, margin rules, and fills you confirmed only in the venue UI. Submitting on chat math is how you get rejects, partials, or unexpected leverage — see confirm fills in the broker, not chat.

What do I read in the broker?

Whatever your venue labels as buying power, available cash, or spendable balance for that account/sleeve — on the official screen. Agent Lane does not invent field names, Agentic menus, or click-paths. Confirm there; then review before place.

Does this replace size from sleeve or review before place?

No. Size from sleeve is the written risk rule. Confirm buying power is the venue cash/BP gate before submit. Never skip review before place is the human gate on the ticket. Confirm fills is after-the-fact venue truth. You need the stack.

Do I invent a buying-power broker UI?

No. Use the official venue balances/buying-power screen and your written sleeve rules. Agent Lane does not invent buying-power dashboards, margin calculators, or Agentic click-paths.

When should I re-check buying power?

Before every live place after a fill, cancel, transfer, or idle gap — and before the first live place after a dry run. Pair with confirm fills in the broker, not chat.

Where do I apply this next?

At review before place: open the official buying power / available cash screen, compare to the ticket size from sleeve rules, then approve or reject. Confirm fills afterward in the broker. Agent Lane publishes the checklist; we do not place trades or invent broker UI.
