When you don't sell them you are signaling to the market that you value them more than the $11 - hence you are buying them.
No, buying is buying ... not selling is not selling. If someone gives me an apple that they grew, I didn't buy it.
But if that same apple would be sold at the market for 2 dollars, and you could only get apples at the market, that person can either give you the apple or two dollars. Same same.
