Options Greeks - Charm

Charm is the seventh options greek to be discussed in my series of articles explaining the options greeks. As with vanna, charm is used by traders who are making delta hedged trades (i.e. trades where the delta of an options or warrants contract does not change over the course of the trade). My explanation of charm will explain what charm represents, and how charm is used to determine how the delta of an options or warrants contract will change over the passage of time.
