built-in study guide
thinkorswim includes a VolumeProfile study and a profile function for custom scripts. Start with the built-in study unless you need a calculation or display it does not expose.

Example request
Create a thinkorswim study that captures the completed prior-day VolumeProfile POC and holds it fixed through the next day. Use explicit row settings and alert once per bar on a completed close crossing above that fixed level.
Add VolumeProfile from the studies library, then set the profile period, price-per-row mode, row height, value-area percentage, expansion behavior, and plot visibility. The study distributes volume across price rows for the selected profile interval. It is different from volume by time bar and from bid-ask delta.
Reference points
A standard volume histogram assigns activity to chart bars. Volume profile groups activity by price row inside a profile interval. These views answer different questions and should not be labeled interchangeably.
Also keep volume profile separate from cumulative volume delta. A price-by-volume distribution does not by itself reconstruct aggressive buying and selling from bid-ask trade classification.
Use the built-in study for its documented profile settings. Consider a custom study only when you need profile values combined with explicit rules, labels, alerts, or other calculations that the built-in interface does not provide.
The thinkScript VolumeProfile function exposes profile data for custom source, but a custom script still inherits the data and calculation constraints of the platform.
AUTOMATIC divides the whole chart's trading range into 85 intervals. TICKSIZE uses the instrument's minimum tick; CUSTOM uses the chosen row height. A changed chart range can therefore change automatic bins even when you are examining the same session.
The default value area is 70%. For tied POC rows, the documented study selects the row closest to the price mid-range, then the lower row if the distance also ties. With on expansion enabled, the profiles count is ignored and only one profile is displayed.
The developing POC can move as trading continues. For an alert against a fixed level, use a completed profile and keep that level unchanged through the comparison interval. A final profile drawn across its earlier bars must not be treated as information already known on those bars.
Pineify thinkScript workflow
Use Pineify when the official study or platform feature does not cover a clearly defined calculation, display, or alert. The agent returns one editable study or strategy file for native review.
Choose a thinkorswim volume indicator from the question you need to answer. Use bar volume for activity by time, VolumeAvg for comparison with a recent baseline, RelativeVolumeStDev for standardized activity, VolumeProfile for activity by price, and cumulative indexes for a specified directional rule. No single volume indicator is best across all uses.
Read guideStandard thinkScript bar volume is not, by itself, a historical bid-ask aggressor split. A script that assigns all volume on an up bar to buying and all volume on a down bar to selling is a price-direction proxy, not true trade-classified CVD. Label such approximations plainly and do not compare them as equivalent to an order-flow data product.
Read guideAdd VWAP from the studies library and choose the reset period and deviation-band settings. Use AnchoredVWAP when you need a fixed starting date. Both studies are already built in, so custom thinkScript is mainly useful for extra rules, alerts, alternate resets, or combined displays.

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 its target platform before relying on its output.
Yes. VolumeProfile is documented in the built-in studies library. It can display a profile, point of control, and value-area bounds using configurable profile and row settings.
No. Volume profile groups activity by price. Cumulative volume delta attempts to accumulate a buyer-versus-seller classification over time. The required data and interpretation differ.
Use the built-in study first. Generate custom thinkScript only when you have a specific extra calculation or output, and verify it against the documented built-in behavior.
Generate one editable thinkScript study or strategy, inspect the source, request focused changes, and complete the final check in thinkorswim.
Pineify generates source code. Review its syntax and chart behavior in thinkorswim before use.
