Bull put credit
Sell a put and buy a lower put. You want spot to stay above the short strike. Defined risk makes it more teachable than a naked short put.
Bear call credit
Sell a call and buy a higher call. You want spot to stay below the short strike. Again, the long wing caps loss versus a naked short call.
