Understanding astro calculations past end of data

I was hoping someone could explain why astro calculations, such as the Mercury Gann Planetary Line and Moon Declinations shown in the attached image, get distorted between the end of daily data and the end of the chart. It seems as if the values are extrapolated using a larger delta time.

Thanks Justin. I can’t be sure from your screenshot, but I think it’s a cryptocurrency and because these are traded 7 days a week you need to turn on the Calendar Days filter so that the future dates are also using calendar days for the astro calculations (by default they just show Monday to Friday).

Right-click on any bar and select Calendar Days from the Filters property, and then delete and reapply the GPL and the future dates will be drawn smoother.

Thank you Darren.
