Hi all,
This is what i have so far. When I have these two filters
together, AB takes a long time to scan through entire database.
So i had to separate them into two different scans. I first
filter the stocks based on my criteria and then apply my own linreg
scan. Is there a more efficient way to do this in one simple
code? Like filtering and then copy results into watchlist (list 0) and
overwriting every time I run it.
thank you for your time

//*Filtering
Filter = Close > 10 AND V >= 500000 AND EMA (V, 30) >= 300000 AND ATR (15) >= 1.2;
ATR15 = ATR (15);
EMA30 = EMA (V, 30);AddColumn (C, "Close");
AddColumn (V, "Volume");
AddColumn (ATR15, "Average True Range");
AddColumn (EMA30, "30 Day Average Volume");
//*
//*LinReg Scan
LinRegVal = LinearReg ( Close, 3 ) ;
LinRegChanVal=LinearReg (Close, 23);
LinRegChanSlope = LinRegSlope (Close, 23);
SDev=StDev (Close,23);
LowerLinRegChanVal=LinRegChanVal-.85*SDev;
UpperLinRegChanVal=LinRegChanVal+.85*SDev;
Cond1 = LinearReg(Close,3) > Ref(LinearReg(Close,3),-1) AND LinRegSlope(Close,23) >= 0 AND Close < LowerLinRegChanVal;
Cond2 = LinearReg(Close,3) < Ref(LinearReg(Close,3),-1) AND LinRegSlope(Close,23) <= 0 AND Close > UpperLinRegChanVal;
Filter = Cond1 OR Cond2;
Buy = Cond1;
Short = Cond2;
ATR15 = ATR (15);
EMA30 = EMA (V, 30);
AddColumn (C, "Close");
AddColumn( Buy, "Buy", 1, colorDefault, IIf( Cond1 == 1, colorGreen, Null ) );
AddColumn( Short, "Short", 1, colorDefault, IIf( Cond2 == 1, colorRed, Null ) );
AddColumn (V, "Volume");
AddColumn (ATR15, "Average True Range");
AddColumn (EMA30, "30 Day Average Volume");
