The challenge is to do it in a CashAcct...Save yourself the confusion and buy a call spread.
Same R:R with 2 positions rather than 3.

Only these are possible: LongStock, LongCall, LongPut, CoveredCall (= LongStock + ShortCall), CashSecuredPut (= ShortPut + Cash), and combinations of them like LongStraddle, LongStrangle, Collar etc....
Ie. for ShortSelling in a CashAcct one has to use CoveredCall or CashSecuredPut.
Of course can use also both at the same time.
