I normally dont increase the ratio more than 2:1 because then risk becomes excessive in case the market suddenly breaks down....normal my ratio is less than 2:1 ( 3:2,5:3 etc) In this trade I have chosen strikes 300 points away...if we select 200 points away, we can get a credit...but with current scenarios 300 points gives me more comfort and maneuverablity.
