Module 1: Getting Started with Pine Script

Setting Up Your Environment

Pine Script works directly in TradingView's web editor—no downloads required. Here's how to access it:

1. Create or log into your TradingView account

2. Open any chart and click the "Pine Editor" button (bottom of screen)

3. Select "New" to start a blank script

Your first view of the editor will show template code. This is normal—we'll modify it step by step.

Understanding Pine Script Structure

Every Pine Script follows this general pattern:

1. Study/Strategy Declaration: Tells TradingView what you're building

2. Settings & Inputs: User-adjustable parameters

3. Calculations: Your indicator's logic

4. Plotting: Visual representation on the chart

Let's break down this simple moving average script:

//@version=5
indicator("My First Script", overlay=true)

// Input
length = input(14, "MA Length")

// Calculation
sma_value = ta.sma(close, length)

// Plotting
plot(sma_value, color=color.blue, linewidth=2, title="Simple MA")
 

Your First Pine Script: Simple Moving Average

Let's create your first working script together:

1. Open Pine Editor and clear any template code

2. Paste the example above

3. Click "Save" and give it a name like "My First MA"

4. Click "Add to Chart"

Congratulations! You've just created a customizable 14-period moving average. Try changing the input value to see how it affects the line.

Module 2: Pine Script Core Concepts

Variables and Data Types

Variables store information your script needs. Pine Script uses these key data types:

• int: Whole numbers (1, 42, -7)

• float: Decimal numbers (3.14, 0.5)

• bool: True/false values

• string: Text ("Buy", "Sell")

• color: Visual colors (color.red, color.green)

Example of declaring variables:

myNumber = 10
myPrice = close
isBullish = close > open
message = "Price is rising"
 

Conditional Logic

Make your scripts smart with if/else conditions:

isUptrend = close > open

if isUptrend
    plot(close, color=color.green)
else
    plot(close, color=color.red)
 

This simple code colors prices green in uptrends and red in downtrends.

Built-in Functions and Libraries

Pine Script includes powerful technical analysis functions like:

• ta.sma(): Simple moving average

• ta.rsi(): Relative Strength Index

• ta.macd(): MACD indicator

• ta.highest(): Highest value in a series

• ta.lowest(): Lowest value in a series

These save you from calculating complex formulas manually.

Module 3: Building Your First Indicators

Trend Following Indicators

Let's create a dual moving average crossover system:

//@version=5
indicator("MA Crossover", overlay=true)

// Inputs for customization
fastLength = input(9, "Fast MA Length")
slowLength = input(21, "Slow MA Length")

// Calculate moving averages
fastMA = ta.sma(close, fastLength)
slowMA = ta.sma(close, slowLength)

// Determine crossovers
crossover = ta.crossover(fastMA, slowMA)
crossunder = ta.crossunder(fastMA, slowMA)

// Plot the moving averages
plot(fastMA, color=color.blue, linewidth=2, title="Fast MA")
plot(slowMA, color=color.red, linewidth=2, title="Slow MA")

// Highlight crossover points
plotshape(crossover, style=shape.triangleup, location=location.belowbar, color=color.green, size=size.small)
plotshape(crossunder, style=shape.triangledown, location=location.abovebar, color=color.red, size=size.small)
 

Momentum Oscillators

Now let's build a simple RSI with overbought/oversold levels:

//@version=5
indicator("RSI with Zones", scale=scale.right)

// RSI Settings
length = input(14, "RSI Length")
overbought = input(70, "Overbought Level")
oversold = input(30, "Oversold Level")

// Calculate RSI
rsiValue = ta.rsi(close, length)

// Plot RSI line
plot(rsiValue, color=color.blue, title="RSI")

// Plot overbought/oversold zones
hline(overbought, color=color.red, linestyle=hline.style_dashed)
hline(oversold, color=color.green, linestyle=hline.style_dashed)

// Color the background when in overbought/oversold zones
bgcolor(rsiValue > overbought ? color.new(color.red, 90) : rsiValue < oversold ? color.new(color.green, 90) : na)
 

Volume-Based Indicators

Volume can provide key trading insights. This script creates a simple volume indicator with moving average:

//@version=5
indicator("Volume Analysis", format=format.volume)

// Settings
volmaLength = input(20, "Volume MA Length")

// Calculate average volume
volma = ta.sma(volume, volmaLength)

// Determine if current volume is above average
isHighVol = volume > volma

// Plot the volume with color based on price movement and volume level
plot(volume, style=plot.style_columns,
    color=close > open
          ? (isHighVol ? color.green : color.lime)
          : (isHighVol ? color.red : color.maroon),
    title="Volume")
         
// Plot the volume average
plot(volma, color=color.blue, linewidth=2, title="Volume MA")
 

Module 4: Advanced Visualization Techniques

Working with Colors and Transparency

Effective visualizations make patterns instantly recognizable. Here's how to use dynamic colors:

//@version=5
indicator("Price Action Heatmap", overlay=true)

// Calculate price change percentage
priceChange = ((close - open) / open) 100

// Create dynamic color based on percentage change
dynamicColor = color.from_gradient(priceChange, -2, 2, color.red, color.green)

// Apply transparency based on volume intensity
normalizedVol = volume / ta.sma(volume, 20)
transparency = math.round(math.min(normalizedVol 100, 90))

// Plot colored background
bgcolor(color.new(dynamicColor, transparency))
 

Drawing Objects on the Chart

Beyond simple plots, Pine Script can add interactive elements:

• Shapes: triangles, stars, circles marking important points

• Lines: support/resistance, trend lines

• Labels: text annotations with values

• Tables: multi-cell data displays

Here's a support/resistance detector with line drawing:

//@version=5
indicator("Key Levels", overlay=true)

// Look back period
lookback = input(14, "Lookback Period")

// Find recent swing high/low
highPoint = ta.highest(high, lookback)
lowPoint = ta.lowest(low, lookback)

// Only draw new lines when we have a new high/low
var line highLine = na
var line lowLine = na

if ta.change(highPoint) != 0
    line.delete(highLine)
    highLine := line.new(bar_index, highPoint, bar_index + 20, highPoint,
                        color=color.red, width=2, extend=extend.right)

if ta.change(lowPoint) != 0
    line.delete(lowLine)
    lowLine := line.new(bar_index, lowPoint, bar_index + 20, lowPoint,
                        color=color.green, width=2, extend=extend.right)
 

Module 5: Strategy Development and Backtesting

Converting Indicators to Strategies

A key advantage of Pine Script is its ability to backtest trading rules. Here's how to convert our MA crossover to a strategy:

//@version=5
strategy("MA Crossover Strategy", overlay=true)

// Inputs
fastLength = input(9, "Fast MA Length")
slowLength = input(21, "Slow MA Length")

// Calculate MAs
fastMA = ta.sma(close, fastLength)
slowMA = ta.sma(close, slowLength)

// Plot MAs
plot(fastMA, color=color.blue, linewidth=1, title="Fast MA")
plot(slowMA, color=color.red, linewidth=1, title="Slow MA")

// Define entry conditions
buySignal = ta.crossover(fastMA, slowMA)
sellSignal = ta.crossunder(fastMA, slowMA)

// Execute trades
if buySignal
    strategy.entry("Buy", strategy.long)

if sellSignal
    strategy.close("Buy")
 

Position Sizing and Risk Management

Smart traders know position sizing is crucial. This enhanced strategy includes basic risk management:

//@version=5
strategy("Risk-Managed Strategy", overlay=true, default_qty_type=strategy.percent_of_equity, default_qty_value=10)

// Risk parameters
stopPercent = input(2.0, "Stop Loss %")
riskPerTrade = input(1.0, "Risk Per Trade %")

// Entry signal (simplified example)
enterLong = close > ta.sma(close, 20) and close > close[1]

// Calculate stop price
stopPrice = enterLong ? close (1 - stopPercent/100) : na

// Position sizing based on risk
posSize = strategy.equity (riskPerTrade/100) / (close - stopPrice)

// Execute trades with calculated position size
if enterLong
    strategy.entry("Long", strategy.long, qty=posSize)
    strategy.exit("SL", "Long", stop=stopPrice)
 

Analyzing Performance Results

After running a strategy, TradingView provides detailed metrics including:

• Total return and drawdown

• Win/loss ratio and profit factor

• Average trade duration

• Maximum consecutive wins/losses

Add this code to your strategy for a performance summary directly on your chart:

// Create performance table
if barstate.islastconfirmedhistory
    var table perfTable = table.new(position.top_right, 5, 4, bgcolor=color.new(color.black, 80))
   
    table.cell(perfTable, 0, 0, "Performance Metrics", bgcolor=color.blue, text_color=color.white)
    table.cell(perfTable, 0, 1, "Net Profit:", text_color=color.white)
    table.cell(perfTable, 1, 1, str.tostring(strategy.netprofit), text_color=strategy.netprofit >= 0 ? color.green : color.red)
   
    table.cell(perfTable, 0, 2, "Win Rate:", text_color=color.white)
    winRate = strategy.wintrades / strategy.closedtrades * 100
    table.cell(perfTable, 1, 2, str.tostring(winRate, "#.##") + "%", text_color=color.white)
   
    table.cell(perfTable, 0, 3, "Max Drawdown:", text_color=color.white)
    table.cell(perfTable, 1, 3, str.tostring(strategy.max_drawdown), text_color=color.red)
