Vineet bhai,
I think what ST da is suggesting is "What happens in the time period between the PUT is sold and CALL is bought". In that time period we will be bearing a risk (probably an unlimited one). However, I am sure with your good knowledge of miniflow and 60 min flow both you can design a system around this. But for the rest of us... we are glad he is selling these options simultaneously

What ST da is going to do today is simultaneously sell a PUT and a CALL with strike prices at least 200 pts apart. So in case of a directional move if one gains the other will lose. If there is no direction as such, then the premiums will decay.
It gets even more interesting to see what the maestro does when the NF price comes at par with the strike prices some days down the line. He has mentioned the word Condor, I am sure it has something to do with that.
Let see...
