Service overview
thinkScript Work for Thinkorswim
Studies, scans, watchlist columns and strategies — and the scripts you already use.
Nordman Algorithms writes thinkScript for traders who use Thinkorswim. Our thinkScript developers work from trading rules, a written specification or just a plain description, or from an existing script that needs changes or fixes.
thinkScript runs inside Thinkorswim: it draws studies and labels on the chart, powers scans and watchlist columns, and tests strategy rules on chart history. Each script is checked where it will be used — on the chart, in a scan or in a watchlist column — before delivery, and you receive the full source and all rights to it.

What We Build in thinkScript
Studies, scans and strategies for Thinkorswim, written by our thinkScript programmers from your rules.
Scans & Watchlist Columns
Scan filters that find symbols meeting your rules, and custom watchlist columns that show your values across a list.
thinkScript Strategies
Entry and exit rules drawn on the chart as simulated trades, so you can test an idea on chart history.
Working with existing code
thinkScript Code Services
A thinkScript developer working on the studies, scans and strategies you already have.
thinkScript Code Modification
New conditions, inputs, labels and alerts added to an existing study or strategy, or a study adapted to run as a scan or watchlist column.
For example
- New condition or input
- Labels and chart bubbles
- Study turned into a scan
- Study as a watchlist column
thinkScript Debugging & Error Fixing
Scripts that will not compile, scans that return nothing, columns that disagree with the chart and “script too complex” errors — traced to the cause and corrected where the platform allows.
For example
- Compile errors
- Scan returns no results
- Column differs from chart
- Script too complex
thinkScript Conversion
thinkScript logic rebuilt in Pine Script, NinjaScript, MQL4/5 or EasyLanguage, and logic from those platforms rebuilt in thinkScript. Results are then compared, taking differences in data and trading sessions into account.
For example
- thinkScript to Pine Script
- thinkScript to NinjaScript
- thinkScript to MQL4/5
- Other platforms to thinkScript
Beyond thinkScript. Projects requiring continuous trading automation or external data processing can run in a separate application, with the necessary logic rebuilt outside thinkScript. For access to a Schwab account, we use the Schwab API. See Thinkorswim development, Python and REST API.

FAQ
thinkScript Development Questions
Practical answers about thinkScript code and Thinkorswim.
Not as a running strategy. Preconfigured conditional orders can be set to be placed or cancelled when a thinkScript condition becomes true. Fuller automation needs an external application, which is covered on our Thinkorswim development page.
Usually, yes. Scripts for charts, scans and watchlist columns differ in the history available to them and in how they calculate — for example, a scan cannot use data from a second timeframe the way a chart study can. That is why moving a study usually means reworking the code. We compare the results under matching settings and explain any differences the platform causes.
Yes, if you have its source. We read the script first to see how it is built, then make the change without disturbing what already works.
Yes. We rebuild thinkScript logic in Pine Script, NinjaScript, MQL4/5 or EasyLanguage, and the other way round, then compare the results, allowing for differences in data and sessions between platforms.
Yes. You receive the full thinkScript source, ready to paste or import into Thinkorswim, with a short guide to its inputs. Source code and full IP ownership are transferred on delivery.
