Alann,
You wouldn't need the last value of Sum
[Var=LastValue(Sum(stema>ltema,Days));] if you selected 'n last
quotations' [or 'n last days'] =1.
Good idea also to add 'debugging' column.
-----
stema=EMA(Close,7);
ltema=EMA(Close,35);
Days=30;
s30 =Sum(stema>ltema,Days);
Var=LastValue(s30);
Filter=Var==Days;
AddColumn(Var,"var");
AddColumn(s30,"s30"); // same if n =1
AddColumn(stema,"stema"); // check
AddColumn(ltema,"ltema"); // check
-----
Regards,
Bob
