Lesson Content
Pine Script is a domain-specific language for creating custom indicators on TradingView. In Indian markets, these indicators can help analyze Nifty 50, Bank Nifty, or individual stocks like Reliance or TCS. Start by declaring your script with //@version=5. Use study() to define indicator properties like title and overlay. For example, study(title='Moving Average Crossover', overlay=true). To calculate a simple moving average, use ma = ta.sma(close, 20). For more complex indicators like RSI, use rsi = ta.rsi(close, 14). Plot your results using plot() or plotshape(). Conditional logic can be added using if statements to create alerts. Remember to optimize your scripts for performance by minimizing calculations in loops.
