Most oscillators give you one line that swings around a midpoint. The Andean Oscillator by alexgrover takes a different approach — it computes two lines, one tracking bull strength and one tracking bear strength, and lets the relationship between them tell you the regime. The math underneath is online recursive envelopes: instead of computing a…
The k-Nearest Neighbors post introduced one half of supervised learning: memorizing models that hold onto every historical bar and search through them at prediction time. This post is the other half. Instead of remembering every example, an online-learning model carries a small set of weights — three numbers, plus a bias term, in this case…
Most trend indicators give you a binary answer: up or down, with maybe a third ‘neutral’ state. That’s useful — but it throws away the most actionable piece of information, which is how confident the indicator is in that call. ChartPrime’s Bayesian Trend Indicator reframes the question as a probability: given the last N bars…
Search TradingView’s community scripts for terms like “machine learning” or “AI” and you’ll find a long list of community-built indicators that lean on one of the simplest and oldest algorithms in ML. k-Nearest Neighbors — the algorithm we’re building from scratch in NinjaScript today — dates to the 1950s and remains one of the most…
The original Williams Vix Fix is one of the cleverest technical indicators ever published — it reverse-engineers the VIX’s bottom-finding behavior and applies it to instruments that don’t have a real VIX. Larry Williams built it so traders could spot capitulation bottoms in stocks, futures, and forex using volatility-of-range math instead of options-derived volatility. ChrisMoody’s…
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…
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…
