Pine Script is a domain-specific language for coding custom technical analysis indicators and strategies on TradingView. It's an invaluable tool for traders who want to backtest their trading ideas against historical data to assess their viability.
What is Backtesting?
Backtesting involves applying trading rules to historical market data to determine the effectiveness of a strategy. It helps identify whether a strategy would have been profitable.
Benefits of Using Pine Script for Backtesting:
Before diving into backtesting, you must set up an environment in Pine Script. This involves understanding the basic elements of the scripting language and how to structure your code.
Pine Script is user-friendly for those with little programming experience. It consists of built-in functions and a simple syntax structure that's easy to learn.
