GTC (Good Till Cancelled) orders are orders that are valid until cancelled. They are most commonly used for placing long term stoploss and target orders. Offering this has been a challenge because exchanges in India don’t support this feature; all pending orders are cancelled by the exchange at the end of every trading day. The few brokers who do offer GTC, essentially re-place all the pending orders which were cancelled by exchange once again on the next trading day. This is not a scalable solution.
