signal code

["john Davis" <buglywugly@xxxxxxxxxxx>]

Inputs: FastLen(4), MedLen(9), SlowLen(18);
Variables: FastAvg(0), MedAvg(0), SlowAvg(0);

FastAvg = AverageFC(Close, FastLen);
MedAvg = AverageFC(Close, MedLen);
SlowAvg = AverageFC(Close, SlowLen);

If CurrentBar > 1 AND (FastAvg[1] > MedAvg[1] OR MedAvg[1] > SlowAvg[1]) AND 
(FastAvg < MedAvg AND MedAvg < SlowAvg) Then
	Sell ("MAC3") This Bar on Close;

this is a signal that comes with 2000i. Can anyone tell me why this signal 
will verify but will
not print any flags on the price bars when turned into a strategy? there are 
others
that are the same.  I would like to write a signal similar that uses the 
linear regression instead of moving
averages. I have written one , but it too verifys but will not print any 
flags. that doesn't mean
it is written correctly. I will never know until I find out why this signal 
has problems.

below is the alert that I use on my linear regression system. I would 
appreciate any help I could
get at turning this into a strategy. I know I can only have a bar close 
strategy, but this would give me an idea if an automated  system would work. 
thanks   John
If Displace >= 0 OR CurrentBar > AbsValue(Displace) Then Begin
	Plot1[Displace](LinearRegValueFC(Price, Length1, 0), "LinearReg");
	plot2[Displace](LinearRegValueFC(Price, Length2, 0), "LinearReg");

   plot3[Displace](LinearRegValueFC(Price, Length3, 0), "LinearReg");
plot4[Displace](LinearRegValueFC(Price, Length4, 0), "LinearReg");

	IF  plot2 > PLOT4 AND PLOT1 crosses under PLOT2  then
		ALERT ("PULLBACK LONG ")


		ELSE

IF  plot2 < PLOT4 AND PLOT1 crosses over PLOT2  then
		ALERT ("PULLBACK SHORT ");

		END;



I know this is sloppy but it is 1 of several, and it works!
