Hello VNS,
In the last 2 sessions, NEST has been really troublesome in the afternoon. Gets disconnected, or the quotes stop updating and then rush all at once, the order book does not respond to "Display" option etc. Just reporting this.
Also, there is a problem with the margin calculator. It is showing lot size 1 for ALL the scrips. Earlier, it used to show lot size one for the far series only.

Please take care of these issues.
