Deprecates the timing field on the Create Transfer request. The field has no effect and will be removed on 2026-08-26; stop sending timing in requests. There is no replacement.

Also corrects the Create Transfer documentation to match actual behavior:

• Documents the supported transfer matrix: ach supports both INCOMING (deposit) and OUTGOING (withdrawal); wire supports OUTGOING only.
• Notes that ach transfers require a relationship_id, and wire transfers require a bank_id whose bank relationship is in APPROVED status.
• Clarifies sandbox behavior: ACH deposits and withdrawals settle instantly, while outgoing wire withdrawals are simulated asynchronously and complete on weekdays only.
• Adds 400, 403, and 422 response definitions.
• timing is no longer listed as required.

Affected Endpoints

• POST /v1/accounts/{account_id}/transfers
• GET /v1/accounts/{account_id}/transfers

The legs field on the order leg schema is now documented as always null for an order leg, since legs are not nested beyond one level. The field's type and runtime behavior are unchanged.

The Pattern Day Trader (PDT) endpoints are deprecated and will be sunset on 2026-07-06. FINRA's revised Rule 4210 replaces the legacy PDT framework with an intraday margin regime, so these endpoints no longer reflect current regulatory behavior. Stop calling PDT-specific endpoints between 2026-06-22 and 2026-07-06, and remove usage before the sunset date.

Affected Endpoints

• GET /v1/trading/accounts/{account_id}/account/pdt/status
• POST /v1/trading/accounts/{account_id}/account/pdt/one-time-removal
