Self-trade prevention and its effect on cover orders

Sun, 21 Jun 2026 00:00:00 +0000

NSE’s self-trade prevention check (STPC) is an exchange-level control that cancels one of two orders entered under the same PAN when they would otherwise match against each other in the same scrip. Because a buy and a sell from the same beneficial owner crossing in the order book produce no change in ownership, the trade would be a self-trade, also called a wash trade. The exchange blocks it by cancelling either the incoming order or the resting one. A cover order (CO) is affected like any other order: if its entry leg or its mandatory stop-loss leg would match another of your own pending orders in that instrument, one of the two is cancelled, which can quietly remove the stop you were relying on.

Cancelling a pending order on Zerodha Kite removes it from the exchange order book and releases any margin blocked for the unfilled quantity. Orders can be cancelled at any point before they are fully executed, as long as they carry status Open (for resting limit and market orders) or Trigger pending (for SL, SL-M and GTT orders). This guide covers single order cancellation, bulk cancellation and cancellation of GTT orders.

Which orders can be cancelled

Order status	Cancellable?
Open	Yes
Trigger pending	Yes
Complete	No, the trade has executed
Cancelled	Not applicable, already cancelled
Rejected	Not applicable, never reached the exchange
AMO (queued)	Yes, before market opens

Partially filled orders can be partially cancelled: the filled portion cannot be reversed, but the unfilled remainder can be cancelled.
