What are the reasons for auto-cancellation in case of GTT Orders?

GTT Order can be auto-cancelled under specific circumstances

1. Corporate Actions – If the company announces events like stock split, bonus issue, merger, or dividend-related adjustments that affect stock availability or pricing.
2. Stock Symbol Change – When the exchange updates the trading symbol/security code of a stock, existing SIPs linked to the old symbol are cancelled.
3. Exchange Mapping Changes – In case the stock is shifted to another exchange category (e.g., SME migration or reclassification), mapped SIP orders may not be valid.

Account Issues – Restrictions such as compliance flags, insufficient margins, or other account-level issues that prevent execution.
