Yes, there is a limit on the total value of orders placed on a single scrip by the client as follows:
Scrips under super multiple order values should be less than 2 Crores and for others it would be less than 15 lakhs.
How do I modify or cancel an order?
Can I place a limit order as AMO?
What are the order types available and where do I find them?
For cover orders, till what time can I square off my open positions manually?
