TheDevashishratio-Momentum

21 Jul

This custom momentum indicator is inspired by Fibonacci principles but builds a unique sequence with steps of 0.5 (i.e., 0, 0.5, 1, 1.5, 2, ...). Instead of traditional Fibonacci numbers, each step functions as a dynamic lookback period for a momentum calculation. By cycling through these fractional steps, you capture a layered view of price momentum over varying intervals.

The "Fibonacci" Series Used
Sequence:
0, 0.5, 1, 1.5, 2, … up to a user-defined maximum

For trading indicators, lag values (lookback) must be integers, so each step is rounded to the nearest integer and duplicates are removed, resulting in lookbacks:
1, 2, 3, 4, ... N

Indicator Logic
For each selected lookback, the indicator calculates momentum as:

Momentum
n
=
close
−
close
[
n
]
Momentum
n
=close−close[n]
Where:

close = current price

n = integer from your series of [1, 2, 3, ... N]

You can combine these momenta for an averaged or weighted momentum profile, displaying the composite as an oscillator.


How To Use
Bullish: Oscillator above zero indicates positive composite momentum.

Bearish: Oscillator below zero indicates negative composite momentum.

Crosses: A cross from below to above zero may signal emerging bullish momentum, and vice versa.

Customization
Adjust max_step to control how many interval lags you want in your composite.

This oscillator averages across many short and mid-term momenta, reducing noise while still being sensitive to changes.

Summary
TheDevashishratio-Momentum offers a fresh momentum oscillator, blending a "Fibonacci-like" progression with technical analysis, and can be easily copy-pasted into TradingView to experiment and refine your edge.

It has become more robust. TheDevashishratio-Momentum (DRM) — Multi-lookback Momentum Oscillator

What it is.
DRM is a momentum oscillator that blends price changes across many lookbacks at once (1, 2, 3… up to a user-set cap). You can weight short lookbacks more, normalize by ATR or Z-Score to make values comparable across symbols/timeframes, smooth the result, and gate signals with higher-timeframe (HTF) trend and simple volume filters. It plots a histogram (the oscillator), a signal line, dynamic/fixed thresholds, and optional entry/exit markers. Alerts are included.

Core idea

Instead of using one period (say, 14), DRM sums ΔP = close − close[n] over a set of integer lookbacks derived from half-steps (0, 0.5, 1, 1.5… → uniques → 1, 2, 3, …).
Each ΔP can be:

Equally weighted

Linearly weighted (shorter lookbacks receive more weight)

Exponentially weighted (aggressively favors short-term momentum)

This gives a smoother, more resilient momentum read that reacts quickly without relying on a single period.

How the oscillator is built

Lookback set

Start with half-steps up to Max half-steps, convert to unique positive integers, and bound within Min / Max lookback.

Weighted momentum blend

Compute ∑ (weightᵢ × (close − close[nᵢ])) and divide by ∑ weights → mom_avg.

Normalization (optional)

None (raw points)

ATR (mom_avg ÷ ATR) for volatility scaling

Z-Score of mom_avg (rolling mean/std) for cross-asset comparability

Smoothing + Signal

EMA smoothing of the oscillator and a second EMA as the signal line.

Thresholds

Dynamic: ±k·σ using rolling stdev of the oscillator

Fixed: user-defined symmetric threshold

Plots

DRM Osc (histogram): main momentum line

Signal (line): crossovers with Osc drive setups

Zero line: mean-reversion reference

Threshold + / −: dynamic or fixed bands

Optional bar colors: teal above +threshold, red below −threshold

Optional markers: triangles for Long/Short setups, circles for suggested exits

Signals & alerts

Long setup: Osc crosses above Signal and Osc > +Threshold (+ optional filters pass)

Short setup: Osc crosses below Signal and Osc < −Threshold

Exit hints (visuals/alerts only):

Long exit when Osc crosses under 0 or an opposite Short setup appears

Short exit when Osc crosses over 0 or an opposite Long setup appears

Note: This is an indicator, not an auto-trader. Use with your own risk rules.

Filters (optional)

HTF trend filter

Pulls a higher-timeframe close and EMA (user-selectable TF and length).

Only allows Long when HTF close > HTF EMA; only Short when HTF close < HTF EMA.

Volume filter

Requires current volume > SMA(volume, lookback), avoiding thin bars.

Inputs (quick reference)

Max half-steps: defines how many half-steps generate the lookback set (larger → more periods blended).

Min/Max lookback bounds: clamps the resulting integer lookbacks.

Weighting: Equal / Linear / Exponential (with α).

Normalization: None / ATR / Z-Score (with ATR len or Z len).

Smoothing: EMA length for oscillator and for signal.

Thresholds: k·σ dynamic band or fixed value.

Filters: HTF timeframe + EMA len; Volume SMA len.

Visuals: Toggle histogram, bar color, and markers.

Recommended starting presets

General swing:

Weighting = Equal, Normalization = Z-Score (zLen 100), Smooth=10, Signal=6, Dynamic threshold ON with k=1.0.

Add HTF filter (e.g., 1H on a 5–15m chart) for higher-quality signals.

Faster intraday:

Weighting = Exponential (α≈0.85–0.92), Smooth=6–8, Signal=4–5, k=1.0–1.2.

Volume filter ON.

Trend following:

HTF filter ON (e.g., chart 15m, HTF 60m; chart 1H, HTF 4H).

Consider Fixed threshold slightly above 0 (e.g., ±0.2 ATR-norm or ±0.5 Z-Score) to avoid noise.

How to trade it (one possible workflow)

Context: Turn on the HTF filter. Trade only with the HTF direction.

Setup: Wait for Osc vs Signal crossover past the relevant threshold.

Entry: Use your own execution rule (e.g., next bar market/limit).

Risk: Place stops based on structure or ATR multiples (e.g., 1.5–2.5×ATR).

Exit:

Scale out near prior swing or when Osc crosses back to 0.

Full exit on opposite setup or when price/structure breaks.

Combine with S/R, session times, and higher-TF structure for confluence.

Strengths & caveats

Pros

Blends many lookbacks → robust momentum estimate

Normalization makes cross-asset/timeframe comparison easier

Simple, interpretable rules with clear thresholds and filters

Works for trend continuation and mean-reversion exits

Caveats

In choppy, low-vol regimes, oscillators can whipsaw. Use filters/thresholds.

Z-Score depends on window size; very small zLen can be unstable.

Dynamic thresholds expand/contract with volatility; fixed may suit some assets.

Tips

Want bar-close signals only? Wrap conditions with barstate.isconfirmed.

If the histogram feels “too hot,” increase Smooth and/or use Equal weights.

If signals are late, try Exponential weights and a shorter Signal len.

For scalping, consider Volume filter ON and slightly higher k (e.g., 1.2).
