Trade Execution, Confirmation and Affirmation
What this domain tests
This domain covers the journey from order to matched instruction: order handling and best execution, block allocation, confirmation, affirmation, matching against standing settlement instructions (SSIs), and exception management before the settlement date.
Order handling and execution
- Order types include market, limit, stop and iceberg; time-in-force variants include day, GTC and IOC.
- Best execution requires consideration of price, cost, speed, likelihood of execution and settlement, size and nature of the order, across named execution venues.
- Institutional orders are often worked as a block and then allocated to underlying funds at an average price, with commission allocated pro rata.
Confirmation and affirmation
- Confirmation: the broker/executing party sends trade details to the client.
- Affirmation: the client (or its investment manager) positively agrees those details, typically via a matching platform such as DTCC CTM, matching on ISIN, quantity, price, settlement date, commission, place of settlement and SSIs.
- SSIs are held in databases such as ALERT and must be re-verified whenever a custodian, account or market changes.
- Under the US T+1 cycle, allocations are due by 7:00pm ET and affirmation by 9:00pm ET on trade date - a same-day operational deadline.
- Unmatched or unaffirmed trades become exceptions, aged and escalated to prevent fails.
Worked example
A broker executes a 30,000-share block at an average price of USD 20.50 and allocates it to three funds: 12,000, 10,000 and 8,000 shares, with commission of USD 0.02 per share. Reasoning: Fund A principal is 12,000 × 20.50 = 246,000, plus 240 commission = 246,240. Fund B is 205,000 + 200 = 205,200. Fund C is 164,000 + 160 = 164,160. The three confirmations must total 30,000 shares, 615,000 principal and 600 commission - any mismatch is an allocation break that must be corrected before affirmation.
Traps that cost marks
- Confusing confirmation (one-way notification) with affirmation (positive agreement).
- Assuming the custodian affirms; the investment manager or client does.
- Using stale SSIs after a custody change, causing a failed settlement.
- Mixing trade date and settlement date in deadline questions.
