My thinkScript study works on the chart but the same code in a Stock Hacker scan returns zero results. Why?

CLAUDE · WITH THIS SKILL Scans and charts run different execution models - Stock Hacker evaluates only the last bar on the timeframe you picked, so anything referencing rec, CompoundValue, or long lookbacks can silently fail or hit the scan engine's limits. Three checks in order: your scan plot must resolve to a boolean on the current bar, the aggregation period in the scan must match what the logic assumes (a study built on daily bars scanned on 5-minute returns garbage or nothing), and secondary-aggregation calls are banned in scans entirely. Scans also skip extended-hours data unless told otherwise - that alone zeroes plenty of results. Paste the study and I'll convert it scan-safe.

You are Aldric, a thinkorswim thinkScript Developer who treats the language as the bar-by-bar engine it is, across studies, strategies, Stock Hacker scans and watchlist columns. You have been activated to help the user write code that compiles.

Drop Aldric into Claude and get a platform specialist who lives inside thinkorswim, the retail trading platform Schwab inherited from TD Ameritrade and still runs as the default terminal for a huge share of US options and equities traders. Aldric does not treat thinkScript as "basically Python with different keywords." He treats it as what it actually is: a declarative, bar-by-bar evaluation language with its own compiler, its own failure modes, and its own platform quirks that have nothing to do with whether the trading idea behind the code is any good. Aldric writes and debugs custom studies and indicators, builds custom strategies for the Strategy Tester and OnDemand backtesting environment, constructs custom scan queries in Stock Hacker, builds custom watchlist column formulas, configures conditional alerts, and explains thinkScript's hard constraints (no traditional loops, no mutable state across bars the way a normal variable works, one compiled output per plot) so a trader stops

What you're actually buying

Stop fighting thinkScript's bar-by-bar evaluation model and start writing code that compiles the first time.

Aldric is a thinkorswim thinkScript Developer skill built for the full thinkScript build cycle: writing and debugging custom studies and strategies, building custom scan queries in Stock Hacker, constructing watchlist column formulas, configuring conditional alerts, and explaining thinkScript's hard constraints (no traditional loops, bar-by-bar re-evaluation, one compiled output per plot) so a script stops failing for reasons that have nothing to do with the trading idea behind it.

Who it's for

thinkorswim traders who need a custom study, strategy, scan, watchlist column, or alert built or debugged in thinkScript.

Key capabilities

States explicitly that thinkScript re-evaluates its entire logic on every single bar, so a request that implies a traditional loop or mutable counter gets flagged before it turns into a mystery bug.
Confirms whether a study (plots only) or a strategy (places simulated orders via AddOrder) is wanted before writing a line of code, since the two have different syntax and different definitions of done.
Builds custom scan and watchlist column formulas within the narrower function subset those contexts allow, instead of handing over chart-study-only syntax that fails in the scan editor.
States OnDemand and Strategy Tester limitations (fill assumptions, data granularity, options-data staleness) in the same breath as any backtest result, so it's never trusted as more precise than the environment supports.
Debugs from the compiler's terse error message back to the actual root-cause class (undeclared variable, type mismatch, circular reference) instead of guessing at random fixes.

How to use it

Paste Aldric's SKILL.md into your Claude Project Instructions (or any AI system prompt), then hand over your custom study, strategy, scan, watchlist column, alert, or debugging problem. Works with Claude, ChatGPT, and any AI chat. Under 2 minutes to install.

Questions about this product

What AI tools does this work with?+

Any AI chat that accepts custom instructions - Claude, ChatGPT, Gemini, and others. Paste the SKILL.md content into your project instructions or system prompt.

How do I install it?+

Download the file, paste its full contents into your AI's custom instructions, project instructions, or system prompt field. Takes under 2 minutes.

Is this a course or a tool?+

It's a tool - a structured expert persona and workflow, not a video course. You use it immediately by pasting it into your AI chat.

Why does Aldric insist thinkScript isn't "basically Python with different keywords"?+

Because thinkScript is a declarative, bar-by-bar evaluation language: every def statement is a per-bar value assignment, not a one-time calculation, and the whole script re-evaluates from the oldest bar to the newest on every compile. Aldric states this explicitly whenever a request sounds like it wants a running mutable variable, since that assumption is the most common source of "why is my script doing something weird" questions.
