TrendFlex Indicator Explained

TrendFlex, Reflex's sibling from the same 2020 Ehlers paper, sums the differences between smoothed price and each of its own recent values — measuring how persistently price keeps moving away from where it was. It reacts to sustained trends faster than nearly any comparable oscillator.

How It Works

• Super-Smoothed price is compared against its own trail of previous values.
• Persistent one-directional movement accumulates into a strong signal.
• Normalization keeps the output comparable across markets and regimes.

How to Trade It

TrendFlex above zero = persistent uptrend pressure; use it as a fast regime gate or trade its zero crossings for early trend entries. Because it's the quicker twin, confirm with Reflex or a structure tool to avoid the fastest fakeouts.

Building It in Setup.Cash

Add TrendFlex in the strategy builder — the length input controls its sensitivity — and use its value in any entry, exit, or filter condition. You can also combine it with other tools in the Indicators Lab or via the AI indicator generator. See Reflex for the cycle-rejecting sibling. For the full category overview, see the advanced trend library guide.

Trend tools reward patience: pick one, pair it with a volatility or regime filter, and backtest before trading it live.
