The platform I’ve been using and building on since NT6.5. Setup, troubleshooting, and what makes it work.
jdehorty’s Nadaraya-Watson Envelope is a kernel-regression non-repainting trend filter. The Rational-Quadratic kernel weighs each historical bar by a smooth, fast-decaying function — recent bars get the highest weight, older bars decay quickly. The weighted sum of close gives a ‘kernel close’ that’s smooth without the lag of a moving average and without the repainting common…

You’ve read enough of the foundational posts in this series to know what OnBarUpdate, OnStateChange, and Plots do in isolation. This post puts them together. By the end of this walkthrough you’ll have a working NinjaScript indicator on your chart that plots a moving average and recolors itself based on slope — green when it’s…
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…
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…
