The term death and golden cross is usually associated with the 50 & 200 day moving averages but in reality it means whenever a short term average falls below the longer time frame average its a death ( bearish) cross alternatively when the shorter term average crosses above the longer term average its a golden ( bullish cross )

on the LTR chart it looks like the 9 EMA ( blue ) is about to fall below the 21 EMA ( purple )

in answer to your other question what we are referring to on PLS is the slope of the averages.
