Nifty futures historical lot size information

Is anyone aware of the history of the change in lot size for nifty futures? I googled it but no concrete info. I could gather this data: Is this correct?

YEAR LOT
|2000-05|200|
|2005-07|100|
|2007-15|25|
|2015-18|75|

64 views and no one could reply :frowning: I thought we had some veterans in this group. @nithin you are my last hope. May you please reply.

ah… I think you are kind of right. In between it was at 50 for a while.

Check this link, has historical bhavcopy in csv. Maybe pick one date for every year and download the bhavcopy and check the lot size. Do share your findings here. If you can’t, let me know, will try to get someone from our office do this.

@dtrade Y u need this information… it does not matter actully… as of now nifty lot size 75…

Thanks @nithin. Why didn’t I think about this solution, I will check it out :slight_smile: by the way congratulations on the EY 2017 award. You are so involved and passionate even after achieving so much, but I guess your benchmarks are higher and I wish you all the best !!!

Hi, @dolphy_crasta its because I am generally very curious, and it can also help others in backtesting :slight_smile:

Hi @nithin I did not go through each year but did a quick check and yes it was at 50 for a short period :slight_smile: Below are the high-level findings.

2000-05 -200
2005-07 -100
2007 - 50
2008 - 25
2009 - 50 (maybe because market fell so much that NSE had to revert to 50)
2010-15 -25
2016-18 - 75 (why did they increase the lot saying they want to protect retail investors. Is this true or is there some other logic?)

Yep SEBI put in a rule saying that minimum value of a contract should be around Rs 5lks for a derivatives contract. Hence the lot size of Nifty and all stock F&O contracts went up in 2016. And yes the reasoning was that SEBI didn’t want extremely small retail investors to take the risks of trading derivative contracts.

Btw thanks for putting this out. :slight_smile:

I think the lot size of 25 is for Mini Nifty contract ,

In the guise of protecting retail investors, " communist mind set " people of SEBI increased contract size , If SEBI intention was really genuine , SEBI was suppose to close Derivatives for retail traders. but still retail traders/investors losing money in derivatives ,( lot of examples on Q &A itself ) funny thing is that , Now SEBI is also regulator for Commodity trading segment , there mini size lot with lowest margins are allowed :grinning::rofl::rofl::joy:

@dtrade, I have same requirement now, but for Individual stocks (I need lot sizes of Individual stocks for past 5 years). As you have researched it for Nifty, can you plz suggest inputs on how can I get it for stocks ?

@dtrade, I checked the bhavcopy, but it does not include lot size… how did you manage to find lot size of NIfty from the Bhavcopy?

I found a way to find the lot size - mathematical way…

Playing with GCD (also called HCF) of OI and closing price variation, could calculate it.

lot

as you can see in the above image lot size changes on the record date…

I have not tested for other scrips…

Good luck!

A little late in the reply, but here is what I do to find the Lot information for every security in Futures & Options segment.

A daily file called Bhavcopy(PR) is available under Equities segment: https://www.nse-india.com/products/content/equities/equities/archieve_eq.htm

The URL of the daily Bhavcopy(PR) file (for 4th January 2010) is:
https://www.nse-india.com/archives/equities/bhavcopy/pr/PR040110.zip

Within this zip file you can find 2 separate files for options and futures: fo04012010.csv and op04012010.csv.

These files have these 2 columns: TRD_QTY and NO_OF_CONT. Lot size should simply be: TRD_QTY/NO_OF_CONT.

This file is available 4th January 2010 onwards.
