The concept of being more short than long in an options spread by creating options spreads where you are selling more structures than you are buying or selling wider structures than the ones you are buying.
Example would be a A butterfly which can be either call or put whose strikes are not equidistant. In a regular butterfly there is equal distance from the long strike (wing) to the short strikes (body) and from the body to the other wing. Think of al butterflies as simply two verticals, one long and one short. The broken wing butterfly simply has the short vertical being wider than the long vertical. In exchange for some directional risk, the spread is opened for a lower price, often even a credit.. This spread is made up of two structures, one long vertical and one short vertical. In the An abbreviation for Broken Wing Butterfly, the short vertical is wider than the long vertical. When you are long this spread, you are said to be in an options position that is “net short”
