“Can the picks from this screen be obtained directly from SIPRO, without using GTR1?”

The short answer is No but you do need a paid subscription to SIPRO to obtain a password to
actually, get the picks to actually invest in the screen.

A longer answer: From SIP you can screen directly for price (in GTR aprc(1) > 5, use the
SIP Volume-Dollar Daily Avg 3m for the GTR adv(1,63) > 63
SIP also has the eps data (all SIP fields are indicated by the *.s format)
But GTR1 also has a data base of daily price for all the stocks which it uses to calculate
linear(1,tr(1,175),1,tr(1,200),1,tr(1,225)) top 25

You could of course use SIP for steps 1 thru 3 which typically results in around 65 picks and
then download the daily price data for those 65 stocks over the last 225 days into a spread sheet
and then calculate total returns for step 4 and step 5.

Or you could be thankful that Robbie has done all the work to reduce your effort by an order of
magnitude for free! And just use GTR1.
