Buying and Selling short

Buying = term to use when buying a currency pair to open a trade.
Selling short = term to use when selling a currency pair to open a trade.
Both terms, refer to things we do to open a trade.
On the other hand, to exit a trade, you will have to use the terms “selling” and “buying-back”. The term “selling” refers to what we do to exit a trade that initially started by “buying”. The term “buying-back” refers to what we do to exit a trade that initially started by “selling-short”.
Basically the term, “selling-short” can be referred to the futures and commodities market. For instance the mentality of buying a field to plant vegetables that will grow in the future is the same thing than buying a currency and to predict that it will eventually go short.
