This is a conditional addition of a column.
It is not possible, as you may read at #32196 and its interesting
replies.
As for the text of an existing column, it is restricted to the last
string value and it is not variable.
As an alternative, you may define two separate columns as
Filter=1;
addcolumn(stochD()>70,"stochD()>70",1.0);
addcolumn(stochD()<=70,"stochD()<=70",1.0);
and see 1 and 0 respectively, after exploring for the n=1 last bar.
Then hit on each caption to gather > or <= securities.
