# Indicators

> The indicator dialog, the full study catalog and study settings.

Everything a chart draws besides its main series is a study: order-flow layers like the heatmap and CVD, profiles, and classic indicators like RSI. Each study has inputs, plots with their own colours, and a place: over the price (overlay) or in its own pane below.

## Add a study

Press <kbd>/</kbd>, click **Indicators** in the top bar, or choose **Add indicator…** from the chart's context menu. The dialog is called **Indicators, metrics and strategies**.

| Section | What it lists |
|---|---|
| Search | Type to filter by name |
| Favourites | Studies you starred. Liquidity Heatmap, CVD, Volume Profile and VWAP are starred by default. |
| Templates | Your saved [indicator templates](/docs/app/layouts#indicator-templates) |
| Official | The curated list, including the Candles and Footprint chart types |
| All | Every study |
| Groups | Heatmaps, Footprint, Volume, Delta / CVD, Positioning, Profiles, Technicals |

Filter the list to **All**, **Overlays** or **Panes**. Click a row to add the study to the active chart; the dialog stays open so you can add several, and the row confirms with **Added** (or **Added ×2** for a second copy). Star a row to make it a favourite. Studies that need live order-flow data carry a badge.

## Study settings

Open a study's settings from its legend row (gear, or double-click the row) or from the object tree.

The settings come in tabs. A simple indicator has **Inputs**; order-flow layers group theirs:

| Layer | Tabs |
|---|---|
| Heatmaps | General, Interaction |
| Liquidation heatmap | General, Interaction, Profile, Leverage bands |
| Volume profiles | Display, Row / Scaling, POC, Value Area (and Session) |
| TPO | General, Session, Row / Scaling, POC, Value Area, Marks, Summary |
| Delta, CVD | Display, Trade size, Average |
| Bar Stats | General, Stats |
| Net Positioning | General, Absorption |
| Bubbles | Display, Filter |

Then, where they apply:

- **Price marker** (pane studies): the current value on the scale (on by default), in the pane at its right edge, a dashed line across the pane at it with its width, and the bar's countdown under the scale's tag.
- **Style**: the colour, width, line style and visibility of each plot, and for pane studies the **Pane**: its own, or shared with the pane above.
- **Aggregate** (order-flow layers): the markets the layer reads, see [Markets of an indicator](/docs/app/heatmap#markets).
- **Defaults** resets to the catalog values. **Cancel** restores what you had. **OK** keeps the changes.

Edits apply to the chart live while the dialog is open.

## The legend and panes

Each study gets a row in the chart's legend with its short name, inputs and current values. Hover the row for show or hide, settings and remove. A script's row also has **Source code** (`{}`, also in its right-click menu): it opens the script in the editor, yours or one from the community library alike.

Pane studies stack below the price pane. Drag the separators to resize them, and drag or scroll a pane's value axis to stretch its scale.

Studies compute only when their inputs or the bars change. The calculations are pure array maths with unit tests.

## Writing your own

Write your own indicators and strategies in [Flowscope Script](/docs/scripting): open the script editor from the bottom bar or **Indicators › My scripts › New script**. The [AI assistant](/docs/app/ai-assistant) can write one from a description.

## Sharing a pane

Two pane studies can draw in one pane, as Delta Volume and CVD often do: right-click the lower study's legend row and choose **Move to › The pane above** (or set **Pane** to "Shared with the pane above" on its Style tab). It keeps its own scale and value tags; its legend row sits under the first. **Move to › A new pane** splits them again.

**Pin to the pane's scale**, in the same menu, draws a shared study on the scale of the pane's own study instead of its own, so the two compare by value (two CVDs, an oscillator and its average). **Its own scale** undoes it.

## Arranging panes

Move the pointer over a study pane and five buttons appear at its top right; the legend row's right-click menu has the same actions.

| Button | Does |
|---|---|
| Maximize | Shows the pane large: the others fold to their names and the chart keeps a quarter. Again restores them. It is a view, not saved with the layout |
| Collapse | Folds the pane to its legend row; again unfolds it. Saved with the layout |
| Up, Down | Moves the pane above or below its neighbour, with the studies sharing it |
| Remove | Removes the study |

Drag the line between two panes to resize them (not while one is maximized).
