These are your Options
In finance, an option is a contract which gives the buyer (the owner or holder of the option) the right, but not the obligation, to buy or sell an underlying asset or instrument at a specified strike price on a specified date, depending on the form of the option.
Don't take Wikipedia's word for it. There are plenty of other options (although they are one of my favourite go-to's)
If these options appear limited in their intense familiarity to all posts of recent, it's worth noting that they are a type of derivative and that a warrant is a type of option.
