Pine Script™ v6 introduces dynamic data requests, advanced text formatting, and enhanced backtesting. Discover how these updates can transform your trading scripts.

TradingView’s Pine Script™ has evolved to version 6, introducing new features and improvements aimed at enhancing script flexibility, runtime efficiency, and developer experience. With updates ranging from dynamic data requests to new text formatting capabilities, Pine Script™ v6 sets the stage for creating more powerful and user-friendly trading tools. This guide highlights the key updates and what they mean for traders and developers.

Key Features of Pine Script™ v6

1. Dynamic Data Requests

Scripts can now call request.*() functions with "series string" arguments, enabling them to dynamically adjust data feeds on any historical bar. Additionally:

  • request.*() calls can now be placed inside loops, conditional structures, and library functions.
  • This enhancement eliminates the need to predefine requests globally, offering greater script flexibility.

Why It Matters
Developers can now build more adaptive strategies and indicators, dynamically pulling data based on changing conditions without rigid pre-setup requirements.

2. Boolean Logic Enhancements

  • Boolean (bool) values are now strictly true or false, never na.
  • Operators like or and and use short-circuit evaluation, skipping unnecessary expressions.

Why It Matters
These changes improve runtime efficiency, especially for scripts relying heavily on conditional logic.

3. Advanced Text Formatting and Sizing

  • The text_formatting parameter allows text objects (e.g., labels, boxes, tables) to display bold or italicized text.
    • Options include text.format_bold, text.format_italic, and text.format_none.
  • Text sizes can now be defined using int values, offering more granular control.

Why It Matters
These updates enhance script aesthetics, helping developers create polished, professional-looking indicators.

4. Improved Strategy Handling

  • Strategies no longer halt at the 9000-trade limit when not in Deep Backtesting mode.
    • Instead, they trim the oldest orders to accommodate new ones, preserving simulation integrity.
  • The new strategy.closedtrades.first_index variable retrieves the index of the earliest non-trimmed order.

Why It Matters
This change ensures uninterrupted backtesting for high-frequency strategies, making it easier to analyze and refine them.

5. Array Indexing with Negative Values

Functions like array.get(), array.set(), array.insert(), and array.remove() now accept negative indices, referencing elements from the end of an array.

Why It Matters
Developers gain a more intuitive way to work with arrays, simplifying operations like accessing or modifying the last few elements.

6. Continuous Futures and Contract Information

  • The syminfo.mincontract variable specifies the smallest tradable unit for the current symbol.
  • Two new variables, syminfo.main_tickerid and timeframe.main_period, reference the main chart’s ticker ID and timeframe, regardless of context.

Why It Matters
These features improve handling of continuous futures and multi-timeframe strategies, addressing long-standing challenges with symbol rollovers and main context references.
