Multi-Account Management Operations Workflow

Running multiple accounts — personal, spouse, IRA, LLC, and managed — multiplies operational complexity. The same signal must reach different accounts with different sizes, tax rules, and custodians, and every account must reconcile daily. The workflow below is the operating manual that prevents the failures multi-account traders hit: misallocation, drift, and unreconciled positions.

Account inventory and classification

List every account with: custodian, registration type (individual, IRA, entity), tax treatment, leverage available, and capital. Classify each as:

• Discretionary personal: you trade freely, tax-sensitive.
• Tax-sheltered (IRA/401k): trade freely, tax-free internally — put high-turnover strategies here.
• Entity: separate books, may have partners — fiduciary duty applies.
• Managed (other people's money): highest governance, written authority required.

Never blend these in execution logic without explicit per-account rules.

The master signal, per-account sizing

Generate one signal (target position as % of account equity), then size per account:

• Apply each account's risk cap (e.g., IRA max 2% per position; managed max 1%).
• Apply tax rules (no short-term gains in taxable; harvest losses opportunistically).
• Round to the account's minimum lot size and precision.

Execution routing

Route orders to minimize market impact and slippage:

• For size under 5% of 1-minute volume: marketable limit at opposite side.
• For larger: slice over 5–15 minutes via TWAP.
• Sequence accounts by priority: tax-sheltered first (no tax friction from partial fills), taxable last.
• Never cross accounts (buy in one, sell in another at the same time) without checking wash-sale and related-party rules — the IRS treats this harshly.

Daily reconciliation

Within 60 minutes of close, reconcile each account:

1. Pull positions and cash from each custodian.
2. Compare to internal expected state.
3. Flag any mismatch > 0.05% of account equity.
4. Resolve before next open; do not let drift compound.

Track a consolidated book: net exposure, gross exposure, sector and factor exposures aggregated across all accounts. A risk that looks fine per account can be extreme in aggregate.

Consolidated reporting

Weekly: per-account PnL, consolidated PnL, exposure report, cost report (commissions, fees, slippage). Monthly: performance attribution by strategy and account, tax-lot review (harvest candidates), drift report vs target allocation. Quarterly: full reconciliation with custodian statements, fee audit, review of any account that deviated >10% from its mandate.

Governance for managed accounts

• Written investment authority (POA or LPA) for every managed account.
• Monthly statement to each managed-account holder.
• Strict segregation: managed funds never flow through personal accounts.
• Conflicts policy: if a signal is capacity-constrained, managed accounts get allocation priority by agreement, not by the manager's preference.

The failure modes

• Allocation drift: one account grows faster and dominates risk. Rebalance allocation quarterly.
• Unreconciled positions: a fill dropped in one account compounds into a tax and risk error. Reconcile daily, no exceptions.
• Wash-sale violations across accounts: the IRS aggregates accounts under common control. Flag any 30-day buy/sell overlap across all your accounts automatically.

Multi-account management is an operations problem dressed as a trading problem: the edge is the signal, the survival is the workflow.
