弹性罗盘 FlexReckon

Reflex × Trendflex zero-lag oscillators + ATR risk · H1 timeframe

Overview

FlexReckon is a two-line rhythm-and-trend framework built on John Ehlers' modern zero-lag oscillators. Reflex tracks the short-term cycle component and supplies the timing cue; its companion Trendflex tracks the trend component and acts as a soft direction gate. A trade is only considered when the rhythm flips, the broader trend does not strongly disagree, and volatility is actually awake.

Signal dashboard — three meters (Reflex cycle, Trendflex trend, ATR activity) with the long / short readout.

How it works

Reflex — cycle line

Price is first de-noised with a SuperSmoother filter (length 16), then measured against a straight-line projection and RMS-normalised. A zero-cross marks a fresh flip of the short-term rhythm — this is the timing trigger.

Trendflex — trend line

Same SuperSmoother pre-filter, but measured against its own running mean. Positive means the trend leans up, negative leans down. It is used as a gate: an entry is vetoed only when Trendflex points strongly the other way (±0.5).

ATR — activity floor

Current ATR(14) must clear 0.5× its 50-bar average, so dead and sleepy sessions are skipped.

Risk model

Stop at 1.5×ATR, target at a 1.8 reward-to-risk ratio, each plan risks 1% of equity, hard cap of 10 entries per day.

Execution flow — Reflex zero-cross → Trendflex gate → ATR activity → enter & protect.

Signal rules

LONG ▲

Reflex crosses up through zero
Trendflex > −0.5 (trend not strongly down)
ATR activity passes

SHORT ▼

Reflex crosses down through zero
Trendflex < +0.5 (trend not strongly up)
ATR activity passes
