DEAR ANIRBANDEB
AS PER MY KNOWLEDGE, WITH OI/VOL RATIO WE SHOULD HAVE LOOK ON PRM AND IV DATA .IF BIG PLAYER BUYING OR SELLING ANY CALL OR PUT OPTION WE CAN CONCLUDE AFTER LOOKING CHANGE IN PRM AND OI CHANGE.
IF BIG PLAYER ARE TAKING NEW POSITION THEN AT THAT TIME OI CHNGE AND VOLUME RATIO WILL BE HIGH RELATIVELY AND AFTER LOOKING AT PRM AND IV DATA WE CAN CONCLUDE ABOUT BIG PLAYER ACTION THAT THEY ARE BUYING OR SELLING ANY PARTICULAR OPTION AT THAT TIME.
DEAR FRIENDS PLZ CORRECT ME IF ANYBODY FOUND MY CONCLUSION WRONG.
