And again.
At 4 o clock I had margin of 25lakhs in my account. At 5 o clock it becomes negative 21lakhs.
So yeah. I will be charged 21k plus gst as penalty now.
Only 2 things possible.
I understand last hour sell off must have increased volatility. But so much difference?
As a precaution, keep tracking your MTM profit and loss to try to figure out extent of increase in used margin. Whenever market moves violently in your favor, free unutilized cash will increase and vice versa.
For an option seller, if underlying index/stock on sold options moves 2% , there might be an increase of 4-5 % in used margin (depending on how far OTM sold options are) when the move is against you.
Had around Rs.4 lakh as margin in Finvasia. Still at market close have Rs.2.2 lakh. So likely not exchange problem.
Yeah I know that. But here am talking about 20 percent increase in margin. I kept 25lakhs which was around 11percent of my funds utilised. It went to negative 21lakhs. So overall margin increased by 20 percent.
Update on this. At 8AM today. Margin was negative 7lakhs. Now tell me what changed from 5PM to mext day 8AM.
I do this too. And loss was only around 3lakhs. So still doesnt make sense.
Index moved around 2 percent yesterday last 1 hour. Lets say margin increased by 10 percent, even then it doesnt make sense. For me margin increased 20 percent.
Can you tell me in terms of percentage of funds utilised please?
25% funds were unutilised. So it dropped down to around 12% unutilised.
Well. Thats still only 13 percent increase.
The increase is somewhat same if i consider what was shown at 8AM today. But till 12PM yesterday it was totally different.
I have not read all the above posts so i apologize if you already know 
but this is common. When mkt closes, the MTM in Positions TAB will be calculated based on LTP but in contract note it will be the adjusted close from EXCH. Usually this is very small and hardly differs but yesterday it was pretty huge.
Example:
So yest the BNF-APR had LTP of 36093 and MTM position was X but the closing rate calculated in Contract NOTE is 36403 (19-APR-note).
So for that long position itself there is 300pt diff per lot and for long position a bit better EoD mtm as compared to mkt closing LTP.
The closing MTM was deeper than what was next day before mkt open as well.
I am sure the closing prices are what changed b/w 5PM and next day. Im still not sure the full effect unless u post exact positions but it has to be somewhat like this.
Yes. No margin penalty was charged. Also no margin limit cross over push notification came to me from finvasia which they do if this happens.
I know this too. MTM loss in postion tab was 6lakhs. Today morning it was 3 lakhs. So I understand if there is 3 lakhs differnce.
But the margin was negative 21lakhs yesterday and negative 7lakhs today morning. The difference is 14lakhs. Anyways let me wait for penalty to be charged. Let me see on which value it will be charged. 
Also. I didnt have any stock pledged. Otherwise I know value of collateral also reduces. So thats ruled out too.
I dont think it is relevant. I have given all values in terms of percentage. My only question was how did margin increase by 20 percent just like that. Plus I even mentioned that I am not sure if zerodha margin calculation is wrong. May be this is how it works. But I have seen many times margin keeps changing when nothing changes.
Example. Few days back I refreshed funds tab. It showed 22lakhs margin available. I refreshed again. It showed 9lakhs. Refreshed again. 21lakhs again. I did it at least 10 times and it kept changing to these two values. And it was refreshed every second. This made me feel that there is a bug in margin calculations.
Having said all of this, I know there is a possibility that I am missing something and I am wrong.
This particular thing is a bug in Zerodha’s system.
When margin is getting updated intraday, for a minute or two, the margin available keeps changing between the two values. Like if around 11 am, margin available is 5L, and the new margin available is supposed to be say 10L, then at the time of updation (around 11:35 or so), it’ll keep getting changed between 5 & 10 when you refresh it.
I first noticed this few months back, thought of creating a ticket, but then left it as it’d be too difficult to explain, plus these guys don’t like to believe their system has flaws anyway…
Exactly this. Its not worth wasting time raising ticket. The regular standard answers are copy pasted.
This looks like a browser caching issue at your system’s end and has nothing to do with margin calculation at Zerodha’s end. Your browser based on the response time of your internet can choose to display margin from local cache or make a fresh request via network to fetch latest data. To avoid this - completely disable cache on your browser especially for sites like zerodha kite / console / etc, where you seek realtime data.
It was on mobile app. Any solution for this?
I see. If it is a mobile app - that is a zerodha controlled environment.
The data under Funds section and many console links therein - open up in a controlled flutter web for which it might be possible for them to manage cache at application level. Otherwise, if it is an API call to get margin data - there might be some caching issue at Cloudflare’s end. And it is quite possible that this is just intermittent issue when cloudflare might be re-routing traffic to different region - and you are caught in the transition.
Either way, it seems to be a caching issue wherein you are not having latest information at all times. It is very hard to debug and reproduce. So you should definitely record a video of the issue in action (if you see it happening again) and raise a ticket.
Trust me. Its not worth the effort of raising a ticket. I have made peace with it.
Thanks for sharing this , I also faced similar issue . will try this.
For the second time in 3 expiries, the margin required feature isn’t working properly. Like today, the margin is showing 0 for selling call options, and when you try to sell it, it says more margin required. Something or the other keeps happening with this feature, please sort it out.
@siva @ShubhS9 - Is this amendment true relating to peak margin penalty? Will it applicable from 1st Aug 2022?
Amendment link - Sebi Tweaks Peak Margin Requirements: How Does It Impact Stock Market Traders
Is it true that penalty charged to client In the last one year since the peak margin regulations came in is to be refunded? Just heard there is a circular from the exchange directing brokers to refund.
