[EquisMetaStock Group] Re: Dave Landry -- Linear Regression Trendline

[pumrysh <no_reply@xxxxxxxxxxxxxxx>]

Philip,

Not sure that Jose may answer this for a bit due to time differences 
so let's see if this will solve your problem. 

The original code was
pds:=Input("Linear Regression Trendline periods",2,2520,63);

You will need to change it to 
pds:=20;

If you are using a 20 period lookback or to whatever you are using. 
This will need to be done to all "input" variables. 

Hope this helps.

Preston
