Getting Started

Prerequisites

1. A TradingView account (free or paid).
2. The Pine Script Editor (accessible via TradingView’s platform).

Steps to Create Your First Script

1. Open the Pine Editor: Click "Pine Editor" at the bottom of TradingView.

2. Write a Basic Script:

   //@version=4  
   study("Simple Moving Average", overlay=true)  
   length = input(14, "MA Length")  
   ma = sma(close, length)  
   plot(ma, color=color.blue)  

3. Apply to Chart: Click "Add to Chart" to visualize the indicator.

Core Components

Variables & Functions

• Variables: Use var to declare (e.g., var float pivotPoint).
• Functions: Built-ins like sma(), rsi(), and crossover().

Plotting Data

Use plot() to display indicators:

plot(close, title="Closing Price", color=color.red)  

Inputs

Allow user customization via input():

length = input(14, "Period Length")  

Building Indicators

Example: MACD Indicator

//@version=4  
study("MACD")  
fastMA = input(12, "Fast MA Length")  
slowMA = input(26, "Slow MA Length")  
signalLength = input(9, "Signal Length")  

macdLine = ema(close, fastMA) - ema(close, slowMA)  
signalLine = ema(macdLine, signalLength)  

plot(macdLine, color=color.blue)  
plot(signalLine, color=color.red)  

Developing Trading Strategies

Moving Average Crossover Strategy

//@version=4  
strategy("MA Crossover")  

fastLength = input(10, "Fast MA")  
slowLength = input(30, "Slow MA")  

fastMA = sma(close, fastLength)  
slowMA = sma(close, slowLength)  

longCondition = crossover(fastMA, slowMA)  
shortCondition = crossunder(fastMA, slowMA)  

strategy.entry("Buy", strategy.long, when=longCondition)  
strategy.entry("Sell", strategy.short, when=shortCondition)  

Backtesting: Use TradingView’s built-in tester to evaluate performance.

Optimization & Best Practices

1. Backtest Thoroughly: Test across multiple assets/timeframes.
2. Avoid Overfitting: Use out-of-sample data.
3. Comment Code: Add notes for clarity (e.g., // Calculate RSI).
4. Use Modular Functions: Break code into reusable blocks.
