Suppose I pledge a share for margin and I will receive 100 rupees . How long does it take to reflect that as margin in my account after my request to pledge it ?
If you place pledge request before 4 PM and authorise the pledge with CDSL before 7 PM, you will receive the margin in your account the next day. You can check this article to know the process.
Is there any limit for Non POA traders on pledge ??
No, there is no limit.
