# Momentum Cycle Sentry Momentum Cycle Sentry is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®. A mirrored momentum oscillator that wraps a symmetric cloud around a zero line: width tracks trend velocity, teal and coral carry the bias, and a neon glow traces each retracement back toward equilibrium. Standard-deviation corridors replace fixed overbought and oversold lines. For trend and pullback traders who want cycles made visible. - Indicator in the LuxAlgo Library, by LuxAlgo, published Feb 19, 2026. - Access: free. - Concepts: [Momentum](https://www.luxalgo.com/library/concept/momentum/) (primary), [Dominant-cycle Detection](https://www.luxalgo.com/library/concept/dominant-cycle-detection/) - Open on Vela: https://vela.luxalgo.com/chart?pineScriptCodeId=cmpwn3pcy0056vhsgkkp5bcmi - Page: https://www.luxalgo.com/library/indicator/momentum-cycle-sentry/ The **Momentum Cycle Sentry** renders [momentum](https://www.luxalgo.com/library/concept/momentum/) as something you can watch breathe: a mirrored oscillator plotted symmetrically around a zero line, built from three nested layers of EMA smoothing, whose cloud width expands as a move gains velocity and contracts as participation fades. Color carries the bias (teal for bullish conditions, coral for bearish) while adaptive volatility corridors replace the fixed thresholds of classic oscillators. ## How to Trade the Momentum Cycle Sentry? - **Expanding teal cloud**: bullish momentum accelerating, trend-continuation conditions. - **Expanding coral cloud**: the bearish equivalent. - **Narrowing cloud**: weakening momentum or pre-breakout compression. - **Neon Path glow**: when momentum cools against the trend, the candles dim and a dotted trace follows the pullback along the curve and its mirror, with X markers on the zero line anchoring its duration. Watch for re-expansion near equilibrium to rejoin the trend. - **Dynamic OB/OS corridors**: standard-deviation zones flag statistically stretched conditions; curvature back toward zero from inside them is the mean-reversion cue. ## Momentum Cycle Sentry Settings - **Base Length**: lookback of the momentum engine: shorter is faster, longer smooths toward macro cycles. - **Smoothing**: EMA smoothing intensity across the layered structure. - **Magnitude**: scales the oscillator's height for chart visibility. - **Retracement Sensitivity**: how aggressively cooling cycles are detected. - **OB/OS Lookback / Inner Multiplier / Outer Multiplier**: the volatility window and the two corridor boundaries. - Style options cover bullish/bearish colors, base transparency, and candle coloring synced to the oscillator. ## Frequently Asked Questions ### Is it a trend-following or mean-reversion tool? Both roles work: follow expanding clouds with the trend, or fade extremes when the oscillator curls back from the outer corridors. Because the corridors scale with volatility, readings stay relevant across quiet and fast markets alike. ### How does it relate to other LuxAlgo momentum tools? It belongs to the library's [momentum family](https://www.luxalgo.com/library/family/momentum/), alongside builds like the [Adaptive Momentum Oscillator](https://www.luxalgo.com/library/indicator/adaptive-momentum-oscillator/). What sets the Sentry apart is the mirrored cloud, the retracement glow, and the standard-deviation corridors. ### Where can I get the Momentum Cycle Sentry? It is freely available from the LuxAlgo Library. The page also supports launching it in Quant, our coding agent, to test momentum-cycle ideas immediately. You can also copy the source code from this page and run it anywhere Pine Script® runs. ## Related indicators - [Momentum Terrain 3D](https://www.luxalgo.com/library/indicator/momentum-terrain-3d/) (Momentum): markdown at https://www.luxalgo.com/library/indicator/momentum-terrain-3d.md - [Adaptive Momentum Oscillator](https://www.luxalgo.com/library/indicator/adaptive-momentum-oscillator/) (Momentum): markdown at https://www.luxalgo.com/library/indicator/adaptive-momentum-oscillator.md - [LTF Momentum Projection](https://www.luxalgo.com/library/indicator/ltf-momentum-projection/) (Momentum): markdown at https://www.luxalgo.com/library/indicator/ltf-momentum-projection.md - [Triangular Momentum Oscillator & Real Time Divergences](https://www.luxalgo.com/library/indicator/triangular-momentum-oscillator-real-time-divergences/) (Momentum): markdown at https://www.luxalgo.com/library/indicator/triangular-momentum-oscillator-real-time-divergences.md - [Candle Breakout Oscillator](https://www.luxalgo.com/library/indicator/candle-breakout-oscillator/) (Momentum): markdown at https://www.luxalgo.com/library/indicator/candle-breakout-oscillator.md - [Rubber Band Liquidity Signals](https://www.luxalgo.com/library/indicator/rubber-band-liquidity-signals/) (Disparity Index): markdown at https://www.luxalgo.com/library/indicator/rubber-band-liquidity-signals.md - [Moving Averages Proximity Oscillator](https://www.luxalgo.com/library/indicator/moving-averages-proximity-oscillator/) (Disparity Index): markdown at https://www.luxalgo.com/library/indicator/moving-averages-proximity-oscillator.md - [ROC-of-ROC](https://www.luxalgo.com/library/indicator/roc-of-roc/) (Momentum & Oscillators): markdown at https://www.luxalgo.com/library/indicator/roc-of-roc.md --- Source: https://www.luxalgo.com/library/indicator/momentum-cycle-sentry/ (LuxAlgo Library).
