TradingView's Pine Script is a powerful tool for creating custom trading indicators and strategies. Combining two indicators in Pine Script can enhance your analysis by providing more reliable signals and reducing false positives. This article will guide you through the process of combining indicators in Pine Script, explain the benefits of this approach, and offer practical examples to implement your own scripts.

Why Combine Indicators?​

Combining technical indicators can significantly improve your trading strategy by:

  1. Filtering False Signals: Using multiple indicators together can confirm or invalidate signals, reducing the risk of acting on false positives.
  2. Providing a Broader Perspective: Different indicators analyze different aspects of market conditions, such as trend direction, momentum, or volatility.
  3. Enhancing Timing: Aligning signals from multiple indicators can help pinpoint better entry and exit points.
  4. Reducing Risk: A multi-indicator approach minimizes the chances of making impulsive decisions based on a single indicator.

Step-by-Step Guide to Combining Two Indicators in Pine Script​

Step 1: Open the Pine Editor​

  1. Log in to your TradingView account.
  2. Open any chart and navigate to the Pine Editor tab at the bottom of the screen.

Step 2: Start with a Basic Script​

Begin with a blank indicator script:

// This source code is subject to the terms of the Mozilla Public License 2.0 at https://mozilla.org/MPL/2.0/
// © Pineify

//======================================================================//
//                    ____  _            _  __                          //
//                   |  _ \(_)_ __   ___(_)/ _|_   _                    //
//                   | |_) | | '_ \ / _ \ | |_| | | |                   //
//                   |  __/| | | | |  __/ |  _| |_| |                   //
//                   |_|   |_|_| |_|\___|_|_|  \__, |                   //
//                                             |___/                    //
//======================================================================//

Step 3: Define Your Indicators​

For this example, we'll combine the Relative Strength Index (RSI) and Exponential Moving Average (EMA):

// RSI Calculation
rsiValue = ta.rsi(close, 14)

// EMA Calculation
emaValue = ta.ema(close, 50)

Step 4: Combine Logic​

You can use logical conditions to combine these indicators. For instance:

  • A buy signal occurs when RSI is below 30 (oversold) and the price crosses above the EMA.
  • A sell signal occurs when RSI is above 70 (overbought) and the price crosses below the EMA.
buySignal = (rsiValue < 30) and (close > emaValue)
sellSignal = (rsiValue > 70) and (close < emaValue)

Step 5: Plot Signals​

Visualize these signals on the chart:

plotshape(buySignal, style=shape.labelup, location=location.belowbar, color=color.green, title="Buy Signal")
plotshape(sellSignal, style=shape.labeldown, location=location.abovebar, color=color.red, title="Sell Signal")

Step 6: Add Alerts (Optional)​

You can set alerts for these signals:

alertcondition(buySignal, title="Buy Alert", message="RSI & EMA Buy Signal Triggered")
alertcondition(sellSignal, title="Sell Alert", message="RSI & EMA Sell Signal Triggered")

Best Practices for Combining Indicators​

  1. Choose Complementary Indicators

    Select indicators that serve different purposes:

    • Trend-following (e.g., Moving Averages).
    • Momentum-based (e.g., RSI or MACD).
    • Volume-based (e.g., OBV).

  2. Avoid Overcrowding

    Limit your combination to two or three indicators to avoid analysis paralysis.

  3. Backtest Your Strategy

    Use historical data to validate your combined indicator's effectiveness before applying it in live trading.

  4. Understand Indicator Logic

    Learn how each indicator works to ensure they complement each other rather than duplicate information.

Example: Combining MACD and RSI​

Here’s an example script that combines MACD and RSI:

//                   |  _ \(_)_ __   ___(_)/ _|_   _                    //
//                   | |_) | | '_ \ / _ \ | |_| | | |                   //
//                   |  __/| | | | |  __/ |  _| |_| |                   //
//                   |_|   |_|_| |_|\___|_|_|  \__, |                   //
//                                             |___/                    //
//======================================================================//

//@version=6
indicator("[Pineify - Best Pine Script Generator] MACD & RSI Combined", overlay=false)

// MACD Calculation
[macdLine, signalLine, _] = ta.macd(close, 12, 26, 9)

// RSI Calculation
rsiValue = ta.rsi(close, 14)

// Buy/Sell Conditions
buyCondition = (macdLine > signalLine) and (rsiValue < 30)
sellCondition = (macdLine < signalLine) and (rsiValue > 70)

// Plotting Signals
plotshape(buyCondition, style=shape.triangleup, location=location.belowbar, color=color.green)
plotshape(sellCondition, style=shape.triangledown, location=location.abovebar, color=color.red)

Common Mistakes to Avoid​

  1. Using Correlated Indicators

  2. Overfitting

    Be cautious not to over-optimize settings during backtesting as this might not perform well in live markets.

  3. Ignoring Market Context

    Indicators work differently in trending vs. ranging markets; adapt accordingly.
