Philly Tide: “GTR1 has not been updated since November. How are we supposed to run the screen to get current picks?”
Philly Tide: “I should have asked is there a current screen posting for this:”

Philly this tread was essentially saying that without Robbie (rgearyiii) personally keeping his free GTR1 screener and backtester up to date and keeping it on line there is no easy way.

As rayvt stated above you can get probably all or most of the data from barchart.com /stocks/indices/nasdaq/nas... With a free account you get custom view with up to 15 criteria. Or subscribe to Portfolio123 and run a screen but it won’t be cheap.

And paper trading a screen with solid backtested results is a waste of time. The results you verify over 6 months or a year are not as statistically valid as backtests over 15 + years. Long backtests with daily starts that don’t drop off a cliff by increasing the number of stocks have a higher likelihood of future performance but even that is not a guarantee of future performance.
