AI indicator builder for TradingView and NinjaTrader
TradeScriptAI turns your indicator rules into editable Pine Script for TradingView or NinjaScript for NinjaTrader 8. Describe the calculations, plots and alerts you want, review the generated code and validation results, then export it to your platform for testing.
A paid plan is required to generate code. Read the examples below before choosing a plan.
Do you need an existing indicator or a custom one?
If you need a standard moving average or RSI, start with the indicators already available in your charting platform. A custom indicator becomes useful when you need your own combination of conditions, display settings or alerts. TradeScriptAI is a code-building tool for those custom rules; it is not a catalog of proven trading signals.
There is no single best indicator for every task. Choose the calculation you need to observe, the platform where it will run and the exact behavior you can verify. An indicator displays calculations and signals; a strategy adds order rules for testing.
Choose the platform where your indicator will run
- TradingView: Pine Script generator
Create chart overlays, oscillator panes and alert conditions in Pine Script v6. Export the source to TradingView’s Pine Editor.
- NinjaTrader 8: NinjaScript generator
Create custom indicators in C# for the NinjaTrader desktop platform. Compile the source in your own NinjaScript Editor.

Indicator prompts you can adapt
These examples specify code behavior. They are not tested strategies or performance claims.
EMA crossover with closed-bar alerts
Create a Pine Script v6 overlay indicator with configurable 9-period and 21-period EMAs. Plot both lines. Mark a crossover only after the candle closes and add separate named alert conditions for upward and downward crosses. Do not place orders.
Check the result: Compare each marker with the two plotted lines on a closed candle. Verify both alert directions and change the input lengths.
RSI threshold indicator
Create a Pine Script v6 indicator in a separate pane. Plot a configurable 14-period RSI with horizontal levels at 30 and 70. Alert when RSI crosses back above 30 or back below 70 on a confirmed bar. Expose the length and levels as inputs.
Check the result: Compare the plotted values with the platform RSI using identical settings. Check that alerts trigger on a crossing, rather than on every bar beyond a level.
NinjaTrader moving-average indicator
Create a NinjaTrader 8 NinjaScript indicator that calculates on bar close. Plot configurable 20-period and 50-period simple moving averages on the price chart. Wait for enough bars before evaluating a crossover. Draw a marker on each confirmed cross and expose the periods as properties.
Check the result: Compile in the NinjaScript Editor and compare the plots with built-in moving averages. Check the first eligible bar and another chart interval.
How to build and check a custom indicator
- Specify the platform, inputs, price source, calculations and chart location. Describe exactly when a signal should appear.
- Generate the code and inspect its validation status. Ask for revisions when the output differs from your rules.
- Export and compile the source in your charting platform. Compare the output against known candles and built-in calculations.
- Test input changes, alerts and real-time behavior. A successful compile does not verify every signal or establish profitability.
Questions about AI-generated indicators
Can I create an indicator without writing the initial code?
Yes. Describe your rules in plain language and use TradeScriptAI to draft the source. You still need to review, compile and test the result in the target platform.
Can I modify an indicator I already have?
You can provide source code you own or have permission to modify and request changes to its inputs, plots or logic. A protected indicator without available source cannot be edited this way.
Does AI generation guarantee non-repainting signals?
No. Specify closed-bar evaluation and inspect any higher-timeframe data requests or offsets. Test historical and real-time behavior in the destination platform; compilation alone cannot establish that a signal will never change.
Can I export the indicator source?
Yes. TradeScriptAI supports code export so you can inspect and test the generated source in the supported platform. Platform accounts and their limits are separate from your TradeScriptAI subscription.
