So, here is my problem with Zerodha margin calculator and how I got scammed (well, trusted margin calculator, took positions, then ended up paying HUUUUUUGE margin shortfall). Don’t know where lies the issue, it is NSE’s problem or Zerodha’s problem.
Scenario below:
Margin Calculator says:
SELL 1 Lot of NIFTY 11500 CE & BUY 1 Lot of NIFTY 11700 CE --> costs you around 29K margin
(add the cost of buying option etc. would make it around 31K or 32K)
Now, the interesting part.
Margin calculator says:
SELL 1 Lot of NIFTY 11500 CE & BUY 2 Lots of NIFTY 11700 CE --> costs you around 17.4K margin
(add the cost of buying option etc. should make it around 20K? no?)
Based on this, I thought I got lucky and, kind, of doubled my positions.
At this stage, even on Kite platform (obviously during market hours), the dashboard also reflected the same, showing that I have enough margin/balance unused.
I went to bed that night not thinking much.
Next morning when I see, KITE says I have HUGEE -ve balance and rest of the story is explained in this thread itself above.
Now, who’s fault is it? Zerodha or NSE?
