How To Create A TradingView Indicator: Easy Pinescript Tutorial

In this Pinescript tutorial, we'll guide you through building a simple TradingView indicator using the latest version of Pinescript. Whether you're a beginner or an experienced trader, this step-by-step guide will help you harness the power of custom indicators for market analysis.

Why Create Custom TradingView Indicators?

TradingView indicators provide actionable insights by visualizing market data. With Pinescript—TradingView’s native scripting language—you can:

• Automate technical analysis (e.g., moving averages, RSI).
• Tailor indicators to your trading strategy.
• Enhance charts with dynamic labels and alerts.

👉 Explore advanced TradingView tools to complement your custom indicators.

Getting Started With Pinescript

Key Concepts

1. Execution Model: Pinescript runs iteratively on each candle (e.g., 300 candles = 300 executions).
2. Plotting: Indicators render directly on charts via plot() functions.
3. Overlay: Set overlay=true to display indicators atop price data.

Example: Simple Moving Average (SMA)

//@version=5  
indicator("My Script", overlay=true)  
plot(ta.sma(close, 21))  

• Line 1: Declares Pinescript v5.
• Line 2: Names the indicator and overlays it.
• Line 3: Plots a 21-period SMA of closing prices.

Pro Tip: Adjust timeframes (e.g., 1-hour vs. daily) to see how indicators adapt dynamically.

Pinescript 5: Key Enhancements

New Features

• Namespacing: Organizes functions (e.g., ta.sma for technical analysis).
• Libraries: Reusable code snippets (import via import User/Library/Version).
• Conversion Tool: Auto-upgrade v4 scripts to v5 in the Pine Editor.

👉 Browse free Pinescript libraries for pre-built functions.

Building a Custom Bitcoin Indicator

Bitcoin Bull Market Support Band

This indicator highlights the 50-week SMA—a key support level for Bitcoin.

//@version=5  
indicator("BullMarketSupportBand", overlay=true)  
maPeriod = input.int(title="Moving Average Period", defval=50, minval=1)  
maValue = ta.sma(close, maPeriod)  
plot(maValue, color=color.new(#00FF00, 90), style=plot.style_area)  

• User Input: Adjust maPeriod in settings.
• Visuals: Green shaded area (style_area) with 90% transparency.

Advanced Features: Labels & Alerts

Code Breakdown

var wait = 0  
wait := wait + 1  
if (low < maValue) and (wait > 12)  
  wait := 0  
  label.new(x=bar_index, y=low, text="💩", size=size.tiny)  
  alert("Buy The Dip "+syminfo.ticker, alert.freq_once_per_bar)  

• Throttling: Alerts trigger quarterly (wait > 12).
• Label: Poop emoji marks dips below support.
• Alert: Notifies via TradingView mobile/desktop apps.
