Coding Tradingview Pine Script Indicators for Beginners
Simple Moving Average (SMA)
The SMA helps smooth out market volatility, making it easier to spot price trends – an essential tool for those new to technical analysis.
How SMA Works
The SMA is calculated by taking the sum of prices over a specific period and dividing it by the number of periods. This approach reduces daily price fluctuations, allowing you to focus on the overall trend.
Different SMA periods serve different purposes:
- 200-day SMA: Highlights long-term market trends
- 50-day SMA: Monitors medium-term market movements
- 9-day SMA: Focuses on short-term price behavior
SMA Pine Script Code
Below is the Pine Script code for creating an SMA indicator:
//@version=5
indicator("Custom SMA", overlay=true)
// Input for SMA length
length = input.int(20, "SMA Period", minval=1)
// Calculate SMA
sma_value = ta.sma(close, length)
// Plot SMA line
plot(sma_value, color=color.blue, linewidth=2, title="SMA")
Trading with SMA
The SMA can provide trading signals through key patterns:
-
Price Crossovers
When the price moves above the SMA, it indicates upward momentum. If the price falls below it, this suggests downward pressure. - Multiple SMA Crossovers
| Signal Type | Description | Common Action |
|---|---|---|
| Golden Cross | 50-day SMA moves above 200-day SMA | Enter long |
| Death Cross | 50-day SMA moves below 200-day SMA | Enter short |
| Support/Resistance | SMA acts as a dynamic price floor or ceiling | Set stop-loss |
Keep in mind that the SMA is a lagging indicator. Its primary purpose is to confirm trends rather than predict them.
For best results, adjust SMA periods based on market activity: shorter periods (10-20 days) for stable markets and longer ones (30-50 days) for volatile conditions.
Next, we’ll dive into the Relative Strength Index (RSI) to analyze momentum.
Relative Strength Index (RSI)
The RSI works alongside the SMA to provide momentum insights, giving traders a more complete picture of market trends.
RSI Basics
Created by J. Welles Wilder Jr. in 1978, the RSI measures price momentum on a scale from 0 to 100. It identifies overbought conditions (above 70) and oversold conditions (below 30), which can indicate possible trend reversals. Here’s how the RSI behaves in different market scenarios:
| Market Condition | RSI Range | Support/Resistance Zone |
|---|---|---|
| Strong Uptrend | 40–90 | 40–50 acts as support |
| Strong Downtrend | 10–60 | 50–60 acts as resistance |
| Sideways Market | 30–70 | Traditional boundaries apply |
Below is a Pine Script example to implement the RSI oscillator.
RSI Pine Script Code
//@version=5
indicator("Custom RSI", overlay=false)
// Input for RSI period
rsi_length = input.int(14, "RSI Period", minval=1)
// Calculate RSI
rsi_value = ta.rsi(close, rsi_length)
// Plot the RSI line
plot(rsi_value, color=color.blue, title="RSI")
// Plot overbought and oversold levels
hline(70, color=color.red, linestyle=hline.style_dashed)
hline(30, color=color.green, linestyle=hline.style_dashed)
Reading RSI Signals
Once you’ve plotted the RSI, use these strategies to interpret its signals:
-
Overbought and Oversold Levels
These levels often signal potential price reversals, especially in sideways markets. However, in trending markets, the RSI may stay in extreme zones for longer periods. As Wilder explained:"Wilder believed that when prices rose very rapidly and therefore momentum was high enough, that the underlying financial instrument/commodity would have to eventually be considered overbought and a selling opportunity was possibly at hand."
-
Trend Confirmation
The RSI’s position relative to the 50 level offers clues about market direction. During bullish trends, the RSI generally stays above 40, while in bearish trends, it tends to remain below 60. -
Adjusting for Volatility
In highly volatile markets, you might need to tweak the RSI’s overbought and oversold levels:Market Condition Overbought Level Oversold Level Usage Standard Settings 70 30 General trading Aggressive Settings 80 20 For volatile markets

Moving Average Convergence Divergence (MACD)
The MACD blends trend analysis with momentum measurement, making it a go-to tool for technical analysis. Created by Gerald Appel in the 1970s and later updated with a histogram feature, it continues to be a key resource for traders.
MACD Components
The MACD has three main parts that work together to help traders understand market movements:
| Component | Description | Purpose |
|---|---|---|
| MACD Line | 12-day EMA minus 26-day EMA | Indicates trend direction and strength |
| Signal Line | 9-day EMA of the MACD Line | Provides trading signals |
| Histogram | MACD Line minus Signal Line | Highlights momentum changes |
"What makes the MACD such a valuable tool for technical analysis is that it is almost like two indicators in one. It can help to identify not just trends, but it can measure momentum as well." – TradingView
MACD Pine Script Code
Here’s how you can create a custom MACD using Pine Script:
//@version=5
indicator("Custom MACD")
// Input parameters
fast_length = input.int(12, "Fast Length")
slow_length = input.int(26, "Slow Length")
signal_length = input.int(9, "Signal Length")
// Calculate MACD values
[macdLine, signalLine, histLine] = ta.macd(close, fast_length, slow_length, signal_length)
// Plot components
plot(macdLine, color=color.blue, title="MACD")
plot(signalLine, color=color.red, title="Signal")
plot(histLine, style=plot.style_histogram, color=color.gray, title="Histogram")
MACD Trading Signals
The MACD generates three key trading signals:
-
Signal Line Crossovers
When the MACD line crosses above the signal line, it indicates a potential bullish move. A crossover below the signal line may signal a bearish turn. These signals are more reliable when they align with the prevailing trend. -
Zero Line Crossovers
A move above the zero line suggests strengthening bullish momentum, while a drop below it points to increasing bearish pressure. These signals are often used to confirm trends. -
Momentum Analysis
Observing changes in the histogram can provide insight into market momentum:Histogram Pattern Market Interpretation Trading Consideration Increasing Positive Values Upside momentum is building Possible continuation of an uptrend Decreasing Negative Values Downside momentum is growing Possible continuation of a downtrend Narrowing Bars Momentum is slowing down Consider locking in profits or adjusting stops
Pairing the MACD with other tools like the RSI can enhance its effectiveness. Use these signals alongside your broader analysis to make more informed trading decisions.
Bollinger Bands
Bollinger Bands Explained
Bollinger Bands, developed by John Bollinger in the early 1980s, are a popular tool for analyzing market volatility. They consist of three main components:
| Component | Description | Trading Significance |
|---|---|---|
| Middle Band | 20-day Simple Moving Average (SMA) | Reflects the overall price trend |
| Upper Band | SMA + 2 standard deviations | Highlights potential resistance levels |
| Lower Band | SMA – 2 standard deviations | Highlights potential support levels |
These bands adjust based on market volatility, creating a range that typically contains most price movements. This flexibility allows traders to identify potential breakouts and shifts in market conditions.
"Bollinger Bands have now been around for three decades and are still one of the most popular technical analysis indicators on the market. That really says a lot about their usefulness and effectiveness."
Bollinger Bands Pine Script Code
Here’s a custom Pine Script code for Bollinger Bands:
//@version=5
indicator("Custom Bollinger Bands", overlay=true)
// Input parameters
length = input.int(20, "SMA Period")
mult = input.float(2.0, "Standard Deviation")
// Calculate Bollinger Bands
basis = ta.sma(close, length)
dev = mult * ta.stdev(close, length)
upper = basis + dev
lower = basis - dev
// Plot bands
plot(basis, "Middle Band", color=color.yellow)
plot(upper, "Upper Band", color=color.blue)
plot(lower, "Lower Band", color=color.blue)
Using Bollinger Bands
Traders use Bollinger Bands to interpret various market scenarios:
- Bollinger Squeeze: When volatility drops, the bands contract or "squeeze", signaling a potential breakout. This often indicates upcoming significant price movements, helping traders prepare for new trends.
-
Overbought/Oversold Conditions: Price interactions with the bands can suggest market reversals:
Band Touch Market Condition Trading Consideration Upper Band Overbought Potential for profit-taking or short positions Lower Band Oversold Possible buying opportunities Middle Band Neutral Indicates overall trend direction - Trend Confirmation: In strong trends, prices may consistently touch or break through the bands. This pattern often confirms the strength of the current trend.
"Bollinger Bands are a versatile technical analysis tool that can be used to identify trends, overbought and oversold conditions, and potential breakouts."
For better accuracy, pair Bollinger Bands with momentum indicators like the MACD or RSI to validate trading signals. They work best as part of a broader trading strategy rather than a standalone tool. Up next, explore how combining these bands with other indicators can enhance your trading approach.
Conclusion
