Help on keywords

Hello Friends, I want to know what this “Last” keyword means . Is it different with “CLose” ?
And if I am running live script and I want the latest price which is the last candle but it is not “Open ,High,Low,Close” of that candle. Then which keyword will give me latest price. Please help.

LAST  means  LTP   Last traded price


means last is the live price ?

Yes. Latest Live price.
