Trend FilterREACT

Long/Short Channel

Use one red/green band for trend direction and as dynamic support, resistance, and a price magnet.

Indicator overview

Use the Reactor to read trend direction and find cleaner pullback or rebound areas. A green channel favors long setups, while a red channel favors short setups. When price returns to the edge of the band, treat it as dynamic support or resistance to watch.

V2 is a high-length, displacement-adaptive low-lag channel that does not require volume. It keeps only green and red direction states and does not borrow the separate Quantum Reactor's gray state. The channel remains a clearly visible ribbon rather than a hairline. V1 remains available for saved charts with its multi-filter and Range ADX initialization behavior. Avoid chasing when price is far from the channel; a wider channel usually means volatility is expanding.

How to read the chart

Green Reactor band
Bullish state above the band; its edge can act as pullback support
Red Reactor band
Bearish state below the band; its edge can act as rally resistance
Upper/lower edges
The visual emphasizes band borders and fill without an extra center line
Channel width
Wider means more volatility or filter dispersion

Signal confirmation

Trend switch

A confirmed close changes from one side of the band to the other and recolors it

Retest confirmation

After a trend forms, price revisits the band edge and closes back with the trend

How to use it

  1. 01

    Use channel color as a direction filter rather than a standalone entry

  2. 02

    The first trend retest is usually easier to risk-manage than chasing a stretched price

  3. 03

    While price is inside the band, wait for a boundary exit instead of treating every swing as a reversal

  4. 04

    Avoid chasing far from the center where mean-reversion pressure is larger

Avoid when:

The first bars after a major gap and prolonged directionless low-volatility markets.

Algorithm versionV2

V2 is the displacement-adaptive low-lag channel; V1 preserves the historical multi-filter model

Band multiplier1.0

Higher is wider and stricter; lower is more responsive

Channel response465

V2 only; calibrated against the official visual with an unknown warmup state, while lower values react faster

Range ADX18

V1 only; filters in-band initialization and never grays an established trend

Show fillOn

Visual only; boundaries and trend state are unchanged
