Code migration guide
Pine Script to thinkScript converter
Pine chart calculations often map well to a thinkScript study, but Pine strategies and mutable state need to be reduced to thinkScript series definitions, plots, alerts, or simulated AddOrder strategy logic.
Generate a thinkScript draft, then save and test it in the thinkorswim editor as the intended study or strategy.
Conversion map
What changes between TradingView and thinkorswim
The migration is a model translation. Use this map to decide where the source behavior belongs before writing target syntax.
| Concern | Source model | Target model | Migration decision |
|---|---|---|---|
| Lifecycle | Code runs sequentially across chart bars. Realtime behavior depends on script type and calculation settings. | Declarative expressions are evaluated over chart data; studies, strategies, scans, and watchlist columns have different contexts. | Choose when each TradingView calculation should run in thinkorswim; matching syntax alone does not preserve timing. |
| Market data and history | Built-in series values such as close carry bar history and use history references such as close[1]. | Definitions and plots form time series and access prior values with bracket indexing or recursive definitions. | Recheck bar indexing, warm-up requirements, timeframe requests, and behavior on an unfinished bar. |
| Indicators and chart output | indicator(), plot(), drawing objects, alerts, and the ta.* namespace define chart output. | Studies use def, plot, painting, and built-in study functions to render chart analysis. | Map calculations before recreating plots, labels, colors, and platform-specific drawing objects. |
| Orders and positions | strategy.* commands create broker-emulator orders for TradingView strategy tests. | Strategies use AddOrder to add simulated orders to charts; platform conditional orders are a separate workflow. | Define fill timing, sizing, pyramiding or hedging, stops, and position ownership for the target platform. |
| Native validation | Save in Pine Editor, resolve compiler errors, add to a chart, then inspect plots, alerts, and Strategy Tester behavior. | Paste into thinkScript Editor, save it as the correct study or strategy, add it to a chart, and inspect plots or the strategy report. | Treat generated thinkScript as a draft until it passes the target editor, chart, and backtest workflow. |
Code example
Moving-average cross: Pine Script to thinkScript
These fragments show where the same signal starts in each API. They are not complete standalone programs; lifecycle setup, inputs, plots, and order handling still depend on the selected artifact.
//@version=6
indicator("MA cross", overlay = true)
fast = ta.sma(close, 10)
slow = ta.sma(close, 20)
longSignal = ta.crossover(fast, slow)
plot(fast)
plot(slow)def fast = Average(close, 10);
def slow = Average(close, 20);
plot longSignal = fast crosses above slow;Workflow
A four-step migration path
Keep generation, target-platform validation, and behavior comparison as separate stages.
- 1
Inventory the source behavior
Separate calculations, plots, alerts, orders, external dependencies, and assumptions in a Pine Editor indicator or strategy source file.
- 2
Choose the target artifact
Decide whether the result is a thinkScript study or strategy definition. This choice controls lifecycle methods and available APIs.
- 3
Rewrite through target APIs
Translate state, series, indicators, drawings, and orders into thinkorswim concepts instead of replacing function names.
- 4
Validate behavior natively
Paste into thinkScript Editor, save it as the correct study or strategy, add it to a chart, and inspect plots or the strategy report.
Manual decisions
Decisions code replacement cannot make
- Choose a thinkScript study for analysis or a strategy for chart-based simulated orders.
- Replace Pine arrays, loops, and mutable objects with supported series or fold-style expressions.
- Separate TradingView alerts and strategy orders into the thinkorswim features that actually support them.
Limitations
What the draft cannot prove
- TradingView and thinkorswim do not share one execution, data, or order model, so behavior can change even when both versions compile.
- Broker, symbol, session, timezone, history, and fill settings can change signals and backtest results on thinkorswim.
- Pineify can generate and revise a thinkScript draft, but the target platform remains the authority for compilation, loading, backtesting, and runtime behavior.
Use cases
When this conversion is useful
- Recreate a Pine indicator as a thinkorswim chart study.
- Map simple Pine strategy signals to a thinkScript strategy report.
- Adapt TradingView plots and alerts to thinkorswim-supported chart output.
