The platform I’ve been using and building on since NT6.5. Setup, troubleshooting, and what makes it work.
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…
You wrote an indicator. It works great on a chart. Now you want to use it from a strategy — you write var sma = MySma(20); in State.DataLoaded and expect the cross-script reference to just work. Or you want to optimize Period in Strategy Analyzer and see which value produces the best backtest. How does…
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…
