I’m not “back to posting.” I’m not starting a schedule. I’m not making promises. I’m not doing the whole “consistent content” thing again just to disappear in a week. If anything, this post is the opposite. This might be my last post. I’m undecided. I’m writing this more for me than for anyone else. I’ve…
In Part 3, we laid the groundwork for our Better Moving Average (BMA) indicator — setting up the file structure, building inputs for multiple moving average types, and wiring up the core logic. But identifying the average is only half the story. In this post, we’re diving into trend detection. 📉📈 You’ll learn how to:…
It’s been a while since I’ve posted here. Life stuff, personal stuff, family stuff—you know, all the stuff. But I’m hoping to get back into a rhythm again. Not daily (let’s be real), but at least once a week. And yes, I will finally finish the series I started forever ago. Probably. In the meantime,…
If you’ve ever wanted to track live trades, monitor bid/ask changes, or build a tool that reacts faster than a bar can form, OnMarketData() is where the action begins. Unlike OnBarUpdate(), which reacts to completed bars, OnMarketData() responds to every change in Level I market data — including bid, ask, and last price updates. That…
Debugging is one of the most underrated skills when it comes to writing NinjaScript indicators. You can have the cleanest code in the world, but if the logic isn’t behaving how you expect—or worse, it’s silently failing—you’ll find yourself stuck staring at a chart wondering what went wrong. In NinjaTrader, debugging isn’t quite the same…
At some point, almost every trader questions whether they should keep going. It doesn’t always happen after a major blowup. Sometimes it comes after months of quiet frustration — when you’re putting in the work, watching the charts, testing ideas, and still not seeing progress. Other times, it shows up after repeated account resets or…
You finally got your custom indicator to compile. You drop it on the chart, ready to feel like a genius—aaaand 💥 Unhandled exception in OnBarUpdate(). If you’ve ever had NinjaTrader slap you with one of those cryptic errors or freeze your backtest halfway through, you’re not alone. The good news? There’s a simple tool built…
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…
