Not able to sell my stocks, which are there in my holdings

I am not Able to sell my stocks, that I have purchased last week. It says an error that the stock is not available in your holdings.

@Akash_49402157 - Please see this announcement: Trade settlement for 8 Sept shifted 🚨

Hi

My MTF GTT sell triggered today but failed and when I tried to sell manually the scrips were missing. 2 queries on this:

  1. Is it an Upstox tech issue due to the settlement holiday change?
  2. On September 9, when settlement resumes, will the scrips be sold/settled automatically at the same sell price that triggered GTT? Because any price lower than the one that triggered GTT would be bad.
