TradingView’s proprietary scripting language for creating custom chart indicators, strategies, and alerts. Pine scripts run on TradingView’s servers. Traders use Pine to encode their own technical analysis logic (for example, defining buy/sell conditions) and then apply it to charts. Pine can generate alerts based on script logic, which can be sent via TradingView’s webhook system. As described by TradingView, “Pine Script…allows you to create custom indicators, strategies, and alerts”. Developers use Pine for quick prototyping or to provide signals to other systems: for instance, a Pine-based strategy could trigger a webhook to a bot when conditions are met.
