I use the GTR1 backtester for SI Pro screening, and use it for about 10% of my portfolio. Thank you for the many years GTR1 has been working wonderfully. I could find alternatives if necessary, but they would be inferior to GTR1. The alternatives might cost $1500 a year and take a few weeks work to learn. I don't have the technical skills to fully host GTR1, but could assist with specific tasks.

Even without data updates, GTR1 is valuable as a backtester. When the data was frozen on 20240930, I started using GTR1 for backtests and Radiscript for screening. Not ideal, but workable. I have a WWL method that is showing promise, but it needs the unique GTR1 daily-start backtesting.
