![SPX chart with a level line on the call wall at 7,810 and a dashed price line at 7,799.25, each with its bell on the price scale](https://archive.firmtape.com/press/features/alerts/lines.d52f855d.webp)

**Why:** an alert where you are looking, on a fixed price or on the call wall, put wall or flip wherever the book moves it. **Where:** right-click the chart or a ladder row (hold for half a second on a phone); the bell on the price scale opens the line's card.

## How to use it

1. Right-click a price on the chart and pick **Alert at 7,809.75** for a **price line** at that price.
2. Near a wall or the flip, pick **Alert when price reaches Call wall** instead: a **level line** that follows that level as the book moves it.
3. On a ladder strike the menu offers **Alert at strike** and **Contract card**; **All alerts** opens the list in your account.
4. Drag a price line up or down to move it; the new price is saved when you let go.
5. Click the bell plate on the price scale for the card: **Once**, **Repeat** or **Delete**.

## How to read it

- A dashed line with a bell is a fixed price; a line named like **Call wall 7,810.00** follows its level.
- A loop mark on the bell means the line repeats.
- A line says nothing about direction: it fires whichever way price meets it.

## Settings and controls

| Control | What it does |
| --- | --- |
| Alert at <price> | A price line, dashed, at that price |
| Alert when price reaches <level> | A level line on the call wall, put wall or flip, which follows it |
| Alert at strike | A price line at a ladder strike |
| bell plate | Opens the card: Once, Repeat, Delete, and when it would have fired on the day on screen |
| drag | Moves a price line; saved on release |

## What it measures

A line fires on the first reading that crosses or touches it, with no waiting period, because you chose the price. A level line reads the volume book's flip, call wall or put wall, the levels the chart draws by default.

## Limits

Up to 25 lines an account, kept on your account so they are on every device you sign in on. A repeating line fires again once price has been 20 SPX points away. Lines fire during the regular session only.

## Questions

**What is the difference between a price line and a level line?**

A price line stays at the price you set. A level line follows the volume book's call wall, put wall or flip, so when the wall moves to a new strike the line moves with it.

**Can I set a line on a phone?**

Yes. Hold your finger on the price for half a second to open the same menu.

**Do my lines follow me to another device?**

Yes. Lines are kept on your account, up to 25 of them.

**What does a fired line send?**

The price, the time in New York, the flip and both walls of the book at that second, and the book it read. Never a trade call.
