Why is my order rejected stating, "The disclosed qty for the symbol should be multiple of lot size (<set_variable>)"?

This error message appears when your disclosed quantity doesn’t meet the rules defined by the exchange for that product type. It often relates to quantity percentages or lot size mismatches.

Understanding disclosed quantity rules

  • Equities (EQ): Disclosed quantity must be at least 10% of the total order and not exceed it.
  • NSE Commodity (NCOM): Minimum disclosed quantity must be 10% of the order quantity.
  • MCX: Minimum disclosed quantity must be 25% of the order quantity.
  • Futures & Options (F&O): Disclosed quantity is not permitted for F&O contracts.

Lot size rule

Regardless of the product type, the disclosed quantity must always be a multiple of the symbol’s lot size. This ensures the order is accepted and processed according to exchange norms.

Example

If you place an order for 1000 shares:

  • Disclosed quantity must be at least 100 (10%) for equities.
  • If the lot size is 10, valid disclosed quantities include 100, 200, 300, etc.
  • A disclosed quantity of 105 would trigger a rejection.
