Every term is defined twice: once the way a filing would put it, and once the way somebody would explain it to you across a table. The second one is usually the one that sticks.

The price of the most recent completed transaction in a security, which is a record of one trade rather than a valuation.
Serviceable on a liquid stock because another trade is a second away. On a suspended one it decays silently while being displayed in the same font as every live price.
Last traded price — the price at which the most recent transaction occurred.
One trade, possibly for a single share. Not "the price", and in an illiquid stock it can be minutes stale.
A quoted price carried forward from an earlier trade because the security has not traded since, so the figure describes a moment that may be hours or days old.
The last traded price is exactly that and nothing more. On a thin name the number on your screen on Friday can be Tuesday’s, and every percentage you compute against it inherits the age.
