John Ehlers’ Noise Elimination Technology (NET) sits on top of any oscillator and outputs how directional its recent values have been — values close to ±1 indicate a clear trend in the underlying, values near zero indicate noise. alexgrover’s RSI With Noise Elimination applies it to a normalized momentum oscillator (an efficiency-ratio form of RSI),…
A standard stochastic uses a single fixed lookback. Pick a small one and the indicator twitches; pick a large one and it lags every turn. LuxAlgo’s Inertial Stochastic takes a different angle: scan all lengths from MinLen to MaxLen and pick the one whose stochastic value sits closest to the previous bar’s chosen value. The…
One SuperTrend is a single voice. Zeiierman’s SuperTrend Cluster is a committee — five SuperTrend members, each with their own ATR length, factor, MA-smoothing type, MA length, and weight. The committee votes; the cluster line moves only when consensus crosses the threshold. The five members can use SMA, EMA, LinReg, WMA, HMA, or RMA smoothing…
A Kalman filter is the natural response to noisy price data — recursively estimate the underlying state and downweight new observations by how much you trust them. BigBeluga’s Kalman Volume Trend takes that idea, applies it to close, and stacks volume context around the resulting trend line: per-bar volume delta bars sized by the normalized…
SuperTrend gives you a binary trend signal: above the band or below it. ChartPrime’s SuperTrend Oscillator turns the same primitive into a graded momentum read by measuring the distance from price to the SuperTrend line, smoothing it, and normalizing — turning a yes/no flip into a continuous oscillator that swings roughly in ±1.7. The result…
Norman Fosback’s Positive Volume Index (PVI) and Negative Volume Index (NVI) are old-school: PVI accumulates only on rising-volume bars (the crowd, the dumb money), NVI only on falling-volume bars (the operators, the smart money). The classic read is that NVI rising while PVI is flat = quiet accumulation. AlgoAlpha’s Smart Money Volume Index takes that…
Standard SuperTrend gives you a clean trailing stop in trends and brutal whipsaws in noise. LuxAlgo’s Evasive SuperTrend is built for the noise problem — when price gets within a configurable Threshold × ATR of the active band, the band actively pushes away from price by Alpha × ATR, dodging the wick that would have…
Bill Williams fractals — five-bar pivots where the middle bar’s high is highest (or low is lowest) — are a clean structural primitive but useless on their own as a trade signal. BigBeluga’s Fractals Trend takes the next step: store the most recent N fractal highs and N fractal lows, smooth them into trend bands,…
capissimo’s Chop and explode (ps5) reframes the classic RSI as a regime detector. Instead of reading 70/30 thresholds for overbought/oversold, this version applies RSI to a minimax-scaled source — the price is normalized to a 0-100 range over a window — and uses 60/40 as the BUY/SELL switches. When the scaled RSI sits between 40…
Most SuperTrend variants are deterministic: ATR × multiplier sets the band width and the trend flips when price closes the wrong side. LuxAlgo’s KNN Supertrend Horizon takes a different swing — it runs a k-nearest-neighbors classifier over recent (RSI, ATR%) feature space, votes on the next-bar SuperTrend direction, EMA-smooths the probability, and only flips when…
