NinjaScript tutorials from someone who’s been writing it since NT6.5. Start at the top if you’re new — or jump to whatever you’re stuck on.
In the last post, we walked through our plan for the Better Moving Average (BMA) — an indicator that lets you switch between multiple moving average types using a single dropdown. Now it’s time to start building. This post focuses on laying the foundation — getting our files created, our workspace organized, and the core…
When you’re building indicators or strategies in NinjaScript, you’ll often find yourself needing to repeat an action—like checking the last 10 bars for a pattern, scanning through a list of values, or cleaning up old draw objects. That’s where loops come in. Loops let you automate repetitive tasks inside your code, saving you from writing…
In the last post, we kicked things off with the big idea: build a better moving average indicator—one that adapts to your logic, reflects it visually on the chart, and gives you full control over how it behaves. But before we start writing code, we need a blueprint. Rushing into NinjaScript without a plan is…
In the world of automated trading and indicator building, logic is everything. Whether you’re trying to trigger a signal when price crosses above a moving average or avoid double entries during a trend, NinjaScript uses one tool more than almost any other: the bool. Booleans (true or false values) are how NinjaTrader scripts think. Combine…
👋 So… you’ve used moving averages. And let’s be honest—they’re fine. Maybe useful. Maybe just noise. Maybe you’ve got an EMA or HMA on your chart that turns green or red when price crosses over. Maybe you’ve tried tweaking someone else’s code, hoping to make it fit your style. But what if you could actually…
Enums (short for enumerations) are a powerful yet simple tool available to NinjaScript developers. They help you organize your code, make your indicator settings user-friendly, and significantly improve readability. If you’ve ever wondered how some indicators provide neat dropdown menus or clearly labeled options, enums are usually behind the scenes making it happen. In this…
When you’re developing indicators in NinjaTrader, it’s easy to focus only on the visuals — plotting lines, marking highs and lows, or coloring candles. But charts alone don’t help much if you’re not watching the screen at the exact moment something important happens. That’s where alerts and sound notifications come in. ✅ With just a…
If you’ve written even a little bit of NinjaScript, you’ve probably used a draw object. They’re one of the most common tools in the platform — and for good reason. Drawing on the chart is straightforward, visual, and incredibly helpful. Whether you’re marking an entry with a dot, showing confirmation text above a candle, or…
When you first start coding indicators in NinjaScript, it’s common to think bar-by-bar: But sometimes, you need to track bigger stories across an entire session —like the highest high and lowest low — and doing that with basic variables can quickly get messy. That’s where creating your own class comes in. 📦 ✅ A class…
In NinjaScript, the built-in tools like Series<T> and Values[] are powerful — but sometimes you need more control over your data. Maybe you want to: That’s where Lists, Dictionaries, and Arrays come in. These C# structures give you a flexible, powerful way to handle historical data exactly the way you need for advanced custom indicators…
