Creating your own Expert Advisor (EA) in NinjaTrader can seem daunting, especially if you’re a beginner. However, you can make your automated trading strategies with the proper guidance and a step-by-step approach. This guide will walk you through the basics of Ninja EA coding for beginners, providing you with the foundational knowledge you need to get started.
Step 1: Understanding NinjaScript
NinjaScript is the programming language NinjaTrader uses to create custom indicators, strategies, and automated trading systems. Since NinjaScript is based on C #, having a basic understanding of it is helpful. If you’re new to programming, don’t worry—plenty of resources are available to help you get up to speed.
Step 2: Setting Up NinjaTrader
Before you start coding, you must set up NinjaTrader on your computer. Here’s how to do it:
- Download and Install NinjaTrader: Visit the NinjaTrader website and download the latest version. Follow the installation instructions to set it up on your computer.
- Create an Account: You’ll need a NinjaTrader account to use the platform. If you haven’t already done so, sign up on their website.
- Connect to a Data Provider: You’ll need market data to test your strategies. Connect NinjaTrader to a data provider like Kinetick, which offers free end-of-day data, or your broker.
Step 3: Creating Your First Strategy
Once you have NinjaTrader set up, it’s time to create your first strategy. Follow these steps:
- Open NinjaTrader: Launch the NinjaTrader platform and login.
- Access the Strategy Wizard: Go to the “Tools” menu and select “New NinjaScript” > “Strategy.” This will open the Strategy Wizard, which allows you to create strategies without writing code.
- Define Strategy Parameters: The Strategy Wizard will guide you through defining your strategy’s parameters, such as entry and exit conditions, order types, and more.
Step 4: Writing Your Code
While the Strategy Wizard is great for beginners, writing your code gives you more flexibility and control. Here’s how to start coding your EA:
- Open the NinjaScript Editor: Go to “Tools” > “NinjaScript Editor.” This is where you’ll write and edit your code.
- Create a New Strategy: Click “New” and select “Strategy.” This will create a new strategy template.
- Understand the Structure: A NinjaScript strategy consists of several methods, including Initialize(), OnBarUpdate(), and OnOrderUpdate(). These methods control how your strategy behaves.

Step 5: Implementing Basic Logic
Let’s implement a simple moving average crossover strategy. This strategy buys when a short-term moving average crosses above a long-term moving average and sells when it crosses below.
- Define Variables: First, define the moving averages in the Variables section.
- Initialize Variables: Initialize the moving averages in the Initialize() method.
- Implement Trading Logic: Add the crossover logic in the OnBarUpdate() method.
Step 6: Testing Your Strategy
After writing your code, testing it thoroughly before deploying it in a live market is crucial.
- Backtesting: Use historical data to see how your strategy would have performed. In NinjaTrader, go to the “Strategies” tab, select your plan, and run it on historical data.
- Optimization: Adjust the parameters to find the most profitable settings. NinjaTrader’s optimization tools can help you find the best parameters for your strategy.
- Forward Testing: Test your strategy in real time using a demo account. This helps ensure it behaves as expected under live market conditions.
Step 7: Deploying Your Strategy
Once you’re confident in your strategy, you can deploy it in a live market.
- Connect to Your Broker: Connect NinjaTrader to your brokerage account.
- Enable the Strategy: In the “Strategies” tab, select your strategy and enable it for live trading.
- Monitor and Adjust: Monitor your strategy’s performance and adjust as needed.
