Your triggered Good Till Triggered (GTT) order pending execution is not visible because, once triggered, it remains valid for the remainder of the trading day as a CNC (Longterm) limit order with Day validity. At the end of the day, the exchange treats it like any other normal day order and cancels it. As a result, your order is not visible from the next day onwards.
