Pine Script v4: Drawing Objects, Series Strings, Smarter Indicators
Pine Script v4 is the fourth major version of TradingView's scripting language, released in 2020. It added programmatic drawing objects, dynamic text through series strings, organized function namespaces, and a stricter type system. I've built more than 30 indicators in v4 over the past year, and these four features changed how I write Pine Script entirely.
Before v4, adding a simple label to a chart meant finding third-party workarounds or skipping it. The type system let na values slip through without warning. Function names felt random. V4 fixed all of that, and the code I write today is cleaner, more visual, and easier to debug than anything I produced before.
