Deviation Trend Profile indicator

1. Introduction

The Deviation Trend Profile indicator, developed by BigBeluga, merges trend analysis via a simple moving average (SMA) with a distribution profile based on ATR-scaled deviations. Its purpose is to highlight trend changes and zones of high or low price concentration, offering a visual map of volatility accumulation since the last market inflection.

2. What Is Deviation Trend Profile?

Deviation Trend Profile is a dual-purpose tool:

Trend: Plots an SMA whose color reflects momentum, and marks the exact bars where bullish or bearish turns begin.
Volatility & Distribution: Overlays six deviation lines (±1, ±2, ±3 ATR multiples) around the SMA, and generates a side histogram showing how many closes have fallen into each of a configurable number of bins between the maximum and minimum deviation levels.

This hybrid approach makes it easy to see when price deviates significantly from its mean and how those deviations are distributed over time.

3. How It Works

3.1. Calculation of SMA and ATR

SMA: Simple moving average of closes over a user-set period (smaLength, default 50).
ATR: 200-bar Average True Range, serving as the volatility baseline for scaling deviations.

3.2. Standard Deviation Levels

Six horizontal lines are drawn around the SMA:

Positive levels:
- +1 = SMA + ATR × mult1
- +2 = SMA + ATR × mult2
- +3 = SMA + ATR × mult3
Negative levels:
- –1 = SMA – ATR × mult1
- –2 = SMA – ATR × mult2
- –3 = SMA – ATR × mult3

These lines help distinguish “normal” price territory (±1 ATR) from stronger expansion zones (±2 and ±3 ATR).

3.3. Trend Change Detection

The indicator computes a normalized momentum:

A cross above +0.1 signals the start of a bullish trend; a cross below –0.1 signals the start of a bearish trend.

Each turn is marked with a point on the SMA.

4. Deep Dive into the Distribution Profile (Histogram)

This advanced feature works as follows:

Initialize bins
Create an array $bin of length bins (default 50), filled with zeros.
Populate bins with closes
For each bar since the last trend change (startIndex):
- Compute the dynamic range: profileRange = maxDev − minDev.
- Compute each bin’s width: step = profileRange / bins.
- Determine which bin a close c falls into by comparing it against lower = minDev + step × i and upper = lower + step, then increment $bin[i].
Determine color scaling
Find maxVal, the highest frequency among all bins. This value is used to set each rectangle’s transparency proportionally (val / maxVal).
Draw rectangles
- Position the histogram to the right by profileOffset bars.
- For each bin with val > 0, draw a rectangle from upper down to lower, with width proportional to val, filled semi-transparently in the current trend color.

The result is a lateral histogram showing price-close concentration since the last turn, highlighting potential dynamic support/resistance zones.

5. Parameter Configuration

Parameter	Description	Default
`smaLength`	Period of the simple moving average	50
`mult1`	ATR multiplier for ±1 deviation	1
`mult2`	ATR multiplier for ±2 deviation	2
`mult3`	ATR multiplier for ±3 deviation	3
`showTp`	Show distribution profile (1 = yes, 0 = no)	1
`bins`	Number of histogram bins	50
`profileOffset`	Horizontal offset (bars) for the histogram	30
`colUpR/G/B`	RGB channels for bullish trend color	18/209/235
`colDnR/G/B`	RGB channels for bearish trend color	250/40/86

6. Default Values and Recommendations

SMA (50) & ATR (200): a balanced medium-term setting.
Deviations 1–3: distinguish consolidation (±1) from strong expansions (±2, ±3).
Bins (50): balance detail and performance; reduce to 30–40 for faster charts, or increase to 70–100 for finer analysis.
Offset (30 bars): keeps the profile clear of price action; adjust to fit your chart width.
Colors: customize to match your template, ensuring good contrast against candles and other studies.
