🛠️ Key Syntax Changes: Pine Script v4 to v5 Conversion
The Pine Script Editor offers an **automatic converter** (usually accessible via the three-dot menu `…` on your script). While this tool handles most changes, manual adjustments are often necessary for complex or older v1-v3 code. Below are the critical changes for v5 compliance:
| Old v4 Syntax | New v5 Syntax | Description |
|---|---|---|
| `study()` | `indicator()` | Function renamed for clearer script type definition. |
| `highest()` | `ta.highest()` | Technical Analysis (TA) functions are now in the `ta` namespace. |
| `input()` | `input.float()`, `input.int()`, etc. | Inputs are now specialized functions for clearer data typing. |
| `iff()` | Ternary Operator (`? :`) | The conditional function has been removed. |
Expert Tip: Always verify the conversion of built-in functions; most now require the ta. prefix.

Frequently Asked Questions (FAQ)
What is the biggest change when converting from Pine Script v4 to v5?
The most significant change is the introduction of **Namespaces**, particularly the ta. namespace. All standard technical analysis functions (like `rsi()`, `sma()`, `crossover()`) now require this prefix in v5 (e.g., `ta.rsi`, `ta.sma`). The declaration function also changed from `study()` to `indicator()`.
