I reported the lagging issue to ToS and was told this:
Regrettably the refresh rate on some of the functions within thinkscript were updated over the past weekend, this changed how custom scripts function when added to the chart. At the moment there is no workaround to get this study to function how it did before, I am submitting feedback on these items so that our developers can review this for future consideration. I do apologize for the inconvenience that this causes, if you have any additional questions or concerns please let us know.
