Do you use debit spread or credit spread more often?

[Jaques]

If you prefer butterfly or condor,then write it if you want.

Debit spread is a cost reduction strategy while credit spread is "protective" write,earning money through decay of time value.

Am I right?

The two are synthetic equivalents if the same strikes are used. That is, selling a 50/55 call vertical is the same as buying a 50/55 put vertical. Selling a 50/55/60 iron butterfly is the same as buying a 50/55/60 call butterfly or put butterfly.

Ic,thank you.

If the options are priced fairly, the only reason to do one synthetic over the other is avoidance of add'l commissions (to close) should the underlying cooperate.
