How to Create Custom Indicators Using FYERS Smart Script?
Smart Script is a feature on FYERS Smart Charts that lets you create and customise technical indicators based on your trading requirements. You can write your own indicator Smart Script using the Script Editor or use FIA (FYERS Intelligent Assistant) to create indicators by describing your requirements.
Creating a Custom Indicator Using Smart Script
To get started:
- Open FYERS Smart Charts.
- Select Smart Script from the right sidebar.
- Choose either Write or paste a script or Use FIA, depending on how you want to create your indicator.
Script Editor – Write or Customise Your Own Indicator
The Script Editor lets you create custom technical indicators by writing or pasting Smart Script.
- Write indicator calculations and define custom trading conditions.
- Configure parameters and how indicator values appear on the chart.
- Paste an existing script and modify its calculations or logic.
- Review and refine your code before applying the indicator.
FIA – Create Indicators Without Coding
FIA (FYERS Intelligent Assistant) lets you generate custom indicator scripts by describing your requirements.
- Create indicator scripts based on your trading logic.
- Specify calculations, parameters and conditions without writing code.
- Modify an indicator by describing the changes you need.
- Ask FIA to help you understand or refine the generated script.
Accessing Saved Smart Scripts
Once you've created and saved a custom indicator, you can access it under Indicators → My Smart Scripts on FYERS Smart Charts.
Select the saved indicator to apply it to your chart.
What if...
| Scenario | Solution |
|---|---|
| The indicator generated by FIA doesn't match my requirements | Continue the conversation with FIA and specify the calculations, conditions or parameters you want to change. |
| I already have an indicator script | You can paste your existing code into the Script Editor and review or modify it according to your requirements. |
| I want to modify a custom indicator | You can edit the indicator's code using the Script Editor or ask FIA to refine a script through natural-language instructions. |
Important: Smart Script is currently labelled as a Beta feature in FYERS Smart Charts. Always review the calculations and conditions of custom or AI-generated indicators before relying on their signals for trading decisions.
