Adding Custom Scripts To tick / range/ renko charts In ThinkOrSwim

[useThinkScript]

Why some scripts and some syntax works on tick / range/ renko charts and some don't; is one of those mysteries of the ages.

ToS Support's canned answer:

The core of the ToS app is based on time-based charts. Tick Charts were introduced to provide real-time price action, however support of custom studies used in tick / range/ renko charts is limited.

The forum's canned answer:
We know that scripts that have any time-based calculations will, by default, not work on tick / range/ renko charts.
Beyond that, what works and doesn't work tends to be a crap shoot.

TRY THIS:

Members have reported having sporadic success with running custom studies on tick charts with extended hours enabled.

Hope this helps.
