# Weekly Stacked Daily Changes

Stacks every week's daily net price changes into a single column, so each weekday's contribution and the week's total volatility sit side by side. It renders with zero configuration, while width, spacing, colors and month markers stay adjustable, and the Bottom Stack Bias option anchors stacks to weekly net return, separating up-weeks from down-weeks at a glance.

**Weekly Stacked Daily Changes** draws each week as a stacked column of its daily net price changes, putting weekday behavior and weekly volatility side by side. It is a compact way to study [day-of-week effects](https://www.luxalgo.com/library/concept/day-of-week-effects/) on any symbol: tall stacks flag volatile weeks, and the mix of bullish and bearish boxes inside each stack shows which days did the work. No initial configuration is needed. The tool renders out of the box, with widths, spacing, colors and month markers left to taste.

## How to Trade the Weekly Stacked Daily Changes?

- **Stack height**: compare column heights to spot volatility regimes. Runs of tall stacks mark expansion, short stacks mark quiet weeks.
- **Box composition**: the same weekday repeatedly printing bullish or bearish boxes hints at recurring session behavior worth investigating.
- **Bottom Stack Bias off**: all stacks share a zero baseline, so height alone ranks weekly volatility.
- **Bottom Stack Bias on**: each stack pivots on its weekly net change. A stack starting below the zero line was a negative week, one starting above was positive.

Month names and boundary lines keep longer studies organized, so scanning a quarter of weekday behavior takes one pass, a natural companion to the library's other [time and seasonality tools](https://www.luxalgo.com/library/family/time-seasonality/).

## Weekly Stacked Daily Changes Settings

- **Width**: fixed width of each weekly column.
- **Offset**: the gap between columns.
- **Spacing**: the distance between the days inside a column.
- **Bottom Stack Bias**: uses the weekly net price change as the stack's bottom boundary.
- Style inputs cover **Bullish Change** and **Bearish Change** colors plus the **Show Months** and **Show Months Delimiter** toggles.

## Frequently Asked Questions

### What does Bottom Stack Bias actually change?
It swaps the baseline. Disabled, every stack starts at zero and heights compare raw volatility; enabled, the weekly net change becomes the pivot, so a stack opening below zero immediately reads as a losing week and one above as a winning week.

### Which tool should I use for weekday statistics?
This indicator shows the raw week-by-week picture; the [Day of Week Price Distribution](https://www.luxalgo.com/library/indicator/day-of-week-price-distribution/) aggregates behavior per weekday instead. Running both works well: one for structure, one for statistics.

### Is Weekly Stacked Daily Changes free to use?
Yes. It sits on the free side of the LuxAlgo Library, available from this page, and it runs in Quant, our coding agent, whenever you want to dig into weekday patterns hands-on. You can also copy the source code from this page and run it anywhere Pine Script® runs.
