Re: Span Margin Calculator similar to Brokerage calculator..
Dear Zerodha,
Can't you make span calculator available on your website. It will be easy for us.
As far as Munish question was, i.e when u buy a put option and sell a put option of lower strike price. Theoretically one should not put in any margin money, because the put sold at lower price are 100% protected by the the put bought at higher price. Of course the number of lots has to be similar.
waiting for your reply.

Nirbhay,
SPAN calculations are really complex, the only way possible is through PC-SPAN that is given by NSE. PC-SPAN needs live data and hence can't really be put up on our website, but we are trying to provide this plugin in our new webbased tool that would be launched..
About hedged positions like the ones that you mentioned on Puts. None of these strategies will get 100% margin benefits by the exchange and it is for a good reason.. They should probably give more benefit, but lesser is not necessarily bad..
For eg, assume you are shorting 5600 puts and buying 5500 puts. Yes you are completed covered and maximum loss is limited. But how will you get into both the positions at same time or exit at same time.
Assume while getting out, you got out of your buy 5500 puts first and as soon as you did it, the market tanked.. what happens now? Imagine if the broker had let the client take this position , assume thinking that maximum loss is 50 points the broker let the client take the position with Rs 2500? This is a huge risk,especially because some stock options can suddenly go illiquid..
As I said, as and when our exchange develops, they should add more of this, but unit better to be conservative rather than aggressive
