What could cause a GTT (Good Till Triggered) order to fail or get rejected?

A GTT order may fail or be rejected due to the following reasons:

• Trigger or limit price outside allowed range: Prices must be within the exchange’s circuit limits.
• Circuit limit breach: The stock may have hit its upper or lower circuit.
• Expired GTT validity: GTT orders expire after a set duration (e.g., 1 year).
• Missing TPIN (for sell orders): TPIN authorization is required to sell shares from your Demat account.(If POA/DDPI is not submitted)
• Insufficient holdings or funds: You must have enough shares (for sell) or sufficient funds (for buy).
• Low liquidity: The stock may not have enough buyers/sellers to execute the order.
• Invalid order configuration: For example, a buy order where the limit price is below the trigger price.
• Technical or broker platform issues: System errors can occasionally cause order failures.
