Order Number

An order number is a unique alphanumeric identifier assigned by the stock exchange's trading system to each individual order submitted by a trading member — serving as the primary reference for tracking, modifying, cancelling, and confirming the status of a specific trade instruction throughout its lifecycle. When an investor places a buy or sell order through Ventura's trading platform, the broker's Order Management System (OMS) assigns an internal order number — and when the order is transmitted to NSE or BSE, the exchange assigns its own exchange-level order number that serves as the authoritative reference for all settlement and dispute resolution purposes. The exchange order number is printed on the trade confirmation, the contract note, and appears in the order book section of the trading platform. For reconciliation and dispute resolution, the exchange order number is the definitive reference — enabling SEBI, the exchange, the clearing corporation, and regulators to trace the complete history of each order from submission through modification, partial fill, complete execution, or cancellation. For investors monitoring multiple simultaneous orders — particularly during active trading sessions with several pending limit orders across different securities — the order number allows unambiguous identification of each specific instruction without confusion between similar orders at nearby price levels. Keeping records of order numbers for significant transactions provides essential documentation for tax computation, compliance verification, and dispute escalation if required.
