Trade enrichment

A raw trade from the exchange carries only the bare facts: security, quantity, price, client. Before a broker can bill the client or meet its own settlement obligations, several other numbers have to be attached to that trade — brokerage, taxes, duties.

Trade enrichment is the step that attaches them. The workbook's own words: it is the process of including additional information in an instruction for a trade that has already been executed.

It happens automatically, right after execution, using rate tables the back office already keeps on file for each client.

The workbook (Chapter 3, section 3.4.1) explains that trade enrichment is performed automatically after each trade execution. At this step, all details needed for the clearing of futures and options contracts, or the settlement of cash securities, are added.

The back office maintains master tables for brokerage rate by client, Goods and Services Tax (GST), stamp duty and Securities Transaction Tax charge tables. When trade data is uploaded to the back office, this information is appended to every trade, and the enriched data is then used to arrive at:

• client-wise brokerage,
• client-wise obligation for securities and funds, and
• all relevant tax amounts to be collected and paid.

Back-office systems then generate the exchange settlement obligations, along with the client-wise contract notes, settlements and tax obligations that follow from the enriched trade.

A client buys 1,000 shares of a listed company at Rs 250 each, a trade value of Rs 2,50,000.

The raw trade record from the exchange shows only: security, 1,000 shares, Rs 250, client code. Trade enrichment appends the client's own rate card and the standard charge tables:

Only after these enrichment steps run does the back office know the client's total payable of Rs 2,50,877.50, and only then can the correct figure appear on the contract note and in the day's settlement obligation to the clearing corporation.

Chapter 3 (section 3.4.1, Trade Enrichment) is the first topic under Back Office Operations, immediately before trade allocation. Expect it tested as a definition question — what trade enrichment means, and what kinds of information get added — and as the explanation for why a raw executed trade is not yet ready for billing or settlement.

• Enrichment adds information to an already-executed trade — it does not change the price or quantity that was traded.
• It happens automatically, driven by master rate and tax tables, not by manual re-entry for each trade.
• It covers both cash securities settlement details and F&O clearing details, not one segment only.
• Do not confuse trade enrichment (adding brokerage and tax data to one trade) with trade allocation (splitting one institutional order across several sub-schemes) — they are sequential but distinct back-office steps.
