Why can't I place orders for any theme? Orders are getting rejected and the page seems unresponsive.

Hey Janki, 

There might be the below reasons for such rejections.

1. Without a Demat account, thematic orders can't be placed, as stocks purchased under the thematic Investing is for delivery.
2. Submission of POA (Power of Attorney) might be pending.
3. Might be because of insufficient funds.
