Why is the error 'Maximum allowed order requests exceeded' displayed?

As a risk management measure, at Zerodha, a single user cannot place more than 3000 orders per day. This restriction is across all segments. There are also limitations at 200 orders per minute. Rate limitations also apply for order modification, where a maximum of 25 modifications are allowed per order. Reach out to Zerodha's support desk (WEB) if there's any difficulty in exiting open positions because of order limitations.
