What does the price per security mean?

Price per security is a key value when determining your investment amount as most projects don't allow for fractional securities to be purchased.

The price per security is the amount that a single security (share or unit) in the issuer's entity costs. Since most issuers don't allow for fractional securities to be purchased, you must buy their securities in increments of the price per security.

This will be enforced by the system during the investment process, so ensure that the amount that you'd like to purchase does not result in a fractional security.
