Have you ever heard about futures trading and wondered how it works or how you might get involved? Perhaps you’ve seen news headlines about commodity prices, like oil or gold, swinging wildly due to global events, or you’ve come across discussions on various forums about leveraging market trends through futures. This guide is designed specifically…
In 1956 Nicolas Darvas was a 35-year-old ballroom dancer touring the world. He didn’t have a Bloomberg terminal, a screener, a chat room, or electronic trading charts. He had cabled stock quotes sent to his hotels in Tokyo, Saigon, and Hong Kong, and a few notebooks. By 1958 he had turned about $36,000 into more…
SuperTrend was a milestone for systematic trend trading — but its biggest weakness is whipsaw. Price wicks past the band by a tick, the trend flips, and you’re stopped out one bar before the real move resumes. HalfTrend by Alex Orekhov (TradingView’s everget) takes a different swing at the problem: instead of tracking the band…
At the end of Calculate Modes, we looked at an arrow-on-condition indicator that behaved differently depending on whether it was running on historical bars or live ticks. The fix in that post was a draw-cleanup pattern — remove the arrow before each OnBarUpdate pass and let the live condition repaint it. Good enough if you…
When you have a position on in NinjaTrader, the chart shows your stop, target, and entry lines — but it doesn’t tell you what any of them are worth. You’re left doing the arithmetic in your head, or looking away from price to read the order panel, right when the trade is live and you…
The default 30/70 RSI thresholds you see in every charting platform were calibrated by J. Welles Wilder in 1978 on flat, range-trading markets. They are mathematically wrong in a trending market — and Constance Brown made that case decades ago in Technical Analysis for the Trading Professional. In a sustained bull, RSI rarely drops below…
If you’ve ever watched a market grind sideways for thirty bars and then explode in one direction without warning, the Squeeze Momentum Indicator is built for exactly that moment. It tells you when volatility is being compressed — Bollinger Bands locked inside a Keltner Channel — and which direction momentum is leaning when the compression…
You wrote your first custom indicator. It plots cleanly, the math is right, you’re happy. Then you want to see it update live instead of only at bar close, so you flip Calculate from OnBarClose to OnPriceChange — a one-line change — and suddenly what shows up on the chart isn’t quite what it was…
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…
