For stock futures lot size change is obvious but why they frequently change index max order limit is still unknown.
It depends on the index levels. Below 17500, Quantity freeze is 2800. When it goes above its 1800. Not sure when is the cut off date for this. But I remember reading about it in this forum when quantity freeze was first introduced.
Nifty moved 6400 to 4500 in three day in Jan 2008 back then there was no such rule.Why now?
Its reviewed at the end of every month, so effect from 1st day of the month
Oh okay. I guess 1st April we were above 17500. So it was brought down to 1800.
Few years back, the max order size used to be 7500, then it reduced to 4950, and now it’s 2800/1800. Also, it never used to get revised at the end of month either. So call it a conspiracy theory or whatever, but many traders including myself feel that this was done to compensate the brokers for the intraday leverage being taken away. In June last year, they first reduced the lot size to 50, then in August, this max order size limit got reduced, and finally in September, the leverage was taken away. People say this was done to prevent freak trades, but that’s just bollocks. Freak trades kept happening after that as well, and still do, though they have reduced.
I remember in early 2009 qty freeze limit for nifty future was 15000 or 300 lots.
