# Indicators and layers

> The Indicators and scripts picker on Pulse - Trade Echo layers, the built-in studies, chart types, compare, events, key levels, alerts and multi-chart layouts.

Everything you add to a Pulse chart comes from one picker, **Indicators and scripts**. Click **Indicators** in the toolbar, or **+ Add** in the legend.

## What's in the picker

| Tab | What you'll find |
|---|---|
| **Favorites** | Indicators, layers and scripts you've starred |
| **My scripts** | Scripts you wrote or copied in Echo Script |
| **Pulse layers** | Dealer positioning and flow drawn on the chart (below) |
| **Indicators** | Built-in studies (below) |
| **Chart types** | How bars draw on this chart |
| **Trade Echo data** | Scripts built on our GEX, charm, dark pool and flow data |
| **Editors' picks** | Chosen by the Trade Echo team each week |
| **Following** | New scripts, versions and comments from authors you follow |
| **Popular, Trending** | The most-added community scripts, and the ones gaining fastest this week |

The search box at the top searches built-in indicators, Pulse layers, your scripts and the community at once.

**The limit:** studies and scripts share 5 slots per chart. When the chart is full, turn one off to make room.

## Pulse layers

These draw Trade Echo's own data on price:

| Layer | What it draws |
|---|---|
| **GEX levels** | Walls and the gamma flip as lines, bubbles or channels, live through the day |
| **Charm drift** | Where dealer charm pushes price into the close |
| **Vanna** | Dealer vanna exposure by strike |
| **Gravity path** | The projected path toward the strongest gamma level |
| **Net flow** | Options net flow in its own pane |
| **Dark pool** | Dark pool levels and the magnet |
| **Flow prints** | Large option prints as bubbles, with an inspector |
| **Key levels** | Prior day high, low and close, and more (below) |
| **Events** | Earnings, Fed and econ releases, with a countdown |
| **Echo map** | Echo mode, on futures charts |

- GEX, Charm, Net flow and Dark pool come from stock options and stock prints, so they don't apply to futures roots.
- For how to read the dealer layers, see [Anchor points and defense lines](https://tradeecho.com/docs/features/dealeredge/anchor-points-defense-lines), [Charm lens](https://tradeecho.com/docs/features/dealeredge/charm-lens) and [Gravity Path](https://tradeecho.com/docs/features/pulse/gravity-path).

## Built-in studies

Moving averages, VWAP, RSI and BT Cloud, plus these 14 studies:

- Bollinger bands, Keltner channels, Donchian channels, SuperTrend
- Ichimoku cloud, Parabolic SAR, Pivot points (daily)
- Opening range
- MACD, Stochastic, Stochastic RSI, ADX and DMI, ATR, On-balance volume

**Opening range** draws the high and low of the first 5, 15, 30 or 60 minutes of the session (15 minutes by default). It has options for a midline, a fill, and drawing while the range is still forming. It needs a chart of 1 hour or less.

Each study has its own settings (inputs and style). Open them from the gear on its legend row. See [Pulse Quick Start](https://tradeecho.com/docs/features/pulse/quick-start#change-settings).

## Chart types and price scale

**Chart types:** Candles, Hollow, Bars, Line, Area, Heikin-Ashi, Baseline and Volume candles.

**Price scale:** Linear, Log or Percent.

## Compare

Compare puts up to 3 more symbols on the chart as percent change. Turning it on switches the chart to the Percent scale.

## Events

The **Events** layer marks earnings, Fed meetings and economic releases (CPI, jobs, PPI, PCE and jobless claims) on the chart, with a countdown to the next one.

## Key levels

Prior day high and low, prior close, premarket high and low, and the average daily range (ADR) high and low.

## Price alerts and cross alerts

**Price alerts:** use **Add alert** in the toolbar or the **Price alerts** panel. An alert made on a drawn line moves with the line, and alerts are checked on our servers.

**Cross alerts:** the bell on a moving average or VWAP alerts you when price crosses that line. They work on 1-minute to 1-hour charts, during regular hours.

## The rail

A strip on the right side of Pulse holds panels: Watchlist, Ticker details, Flow, Plans, Price alerts, the Echo Script editor and More widgets.

## Multi-chart

The **Chart layout** button shows one, two (side by side or stacked), three, four, six or eight charts at once. Sync switches keep the charts in step:

- Symbol
- Interval
- Crosshair
- Time
- Date range

On narrow screens Pulse shows one chart.
