Have you checked this one out with an options calculator or a real
ticker, Michael? Please post the details if so.
I think you are saying, add 185p -190p -190c + 3*195c to the original
condor, 175c - 180c - 190c +195c getting
175c -180c +185p -190p -2*190c +4*195c. The adjustment seems to
require a large debit because of the 3 long 195 calls and according to
a rough expiration graph I drew, the trade will lose big at 190, total
disaster at 195 and be unprofitable if the position ends up below 205
or so.
