custom volatility-trend study
Supertrend is a volatility-band state indicator built from price and an average true range calculation. Implementations can disagree on smoothing, band carry-forward, and reversal rules.

Create a thinkorswim Supertrend upper study with hl2 as the basis, configurable ATR length and multiplier, Wilder smoothing, documented final-band carry rules, colored state line, and completed-bar transition alerts.
A reviewable thinkorswim Supertrend study needs a stated price basis, ATR length, ATR smoothing method, multiplier, final-band rules, and state transition condition. thinkScript provides true-range and moving-average building blocks, but the exact Supertrend formula should be written down rather than inferred from the name.
Reference points
Implementations may use different price bases, Wilder or another ATR smoothing method, distinct initialization, or different comparisons on an equal-value bar. Each choice can move a reversal by one or more bars.
Preserve these choices as inputs or comments, then compare the resulting line and state across a known sample before adding signals.
A color change can mark the indicator’s trend-state transition. It does not define position size, entry timing, exits, or risk. Add those only in a separately specified strategy.
Pineify can generate the study and later convert explicit transitions into simulated strategy orders. Test the study first so strategy errors are not confused with indicator errors.
Pineify thinkScript workflow
Give the Coding Agent the formula, inputs, plots, alerts, and edge cases. It returns one editable study or strategy file and keeps focused revisions in the same code artifact.
thinkorswim includes a studies library for common indicators and a thinkScript editor for custom studies. There is no universal best indicator for day trading. Select a study by its calculation, inputs, chart context, and failure modes, then test whether its signal adds information beyond price alone.
Read guideThe thinkScript Alert function accepts a condition, message, alert type, and sound. Put it in a study when the trigger depends on custom calculations. Use a crossing condition when you want one event at a transition rather than an alert on every bar where a state remains true.
Read guideFor a basic thinkorswim Donchian channel, plot Highest(high, length) and Lowest(low, length), with an optional midpoint. For breakout logic, compare the current bar with the prior channel value so the current high or low does not move the threshold at the same time. Use separate entry and exit lengths if that is part of the rule.

Pineify provides information and code-generation assistance, not investment advice. Generated scripts, strategy reports, simulations, and historical examples cannot predict prices or guarantee returns. Review every script and test it in thinkorswim before relying on its output.
The official library provides ATR and true-range building blocks. A Supertrend formula can be implemented as a custom thinkScript study, but its variant must be specified.
At minimum, define the price basis, ATR length, ATR smoothing, multiplier, final-band carry rule, initialization, and state reversal condition.
Yes. Specify whether the alert fires on the first state change, on a completed bar, and how often it may repeat. Verify the state line before enabling the alert.
Generate one editable thinkScript study or strategy, inspect the source, request focused changes, and complete the final check in thinkorswim.
Pineify generates source code. thinkorswim remains the platform authority for parsing and chart behavior.
