Opening purchases/ Closing sales

I am having difficulty understanding closing and opening transactions. I understand it when I read, and then when taking the practice exams, I get them all wrong.

Any tips please?

Hi, it’s best to think of this in two parts:

  • Opening vs closing
  • Purchase vs sale

Opening vs closing

  • If the investor currently is starting a new position, then they make an opening transaction
  • If the investor currently is ending an existing position, then they make a closing transaction

Purchase vs sale

  • If the investor wants to buy the option, they make a purchase to go long
  • If the investor wants to sell the option, they make a sale to go short
