Do i get premium on shorting option in MIS?


Yes you get the premium, but ideally you should not be using it to take next positions from the premium received. 

For MIS option selling, is only half the premium shown in Kite funds page? I sold two lots of NIFTY options MIS expiring today, but its showing premium for only one lot in Kite funds page. For NRML selling, it shows the full premium.
