Create powerful, informative alerts by incorporating dynamic data directly in your alert messages.

### Variable Placeholders

You can customize alert messages with real-time data using special placeholders. For example:

```
{{ticker}}:{{exchange}} {{condition_type}} {{condition_source_1}}
```

When triggered, this might display as: `TSLA:NASDAQ Crossing Down 144.68`

### Examples

Simple price alert:

```
Alert: {{ticker}}:{{exchange}} {{condition_type}} {{condition_source_1}} 
```

Multi-condition alert:

```
Alert: {{ticker}}:{{exchange}} crossing {{cond0.src1}} AND {{ticker}}:{{exchange}} crossing {{cond1.src1}} AND {{ticker}}:{{exchange}} crossing {{cond2.src1}} 
```

<Note>`src1` is a fixed parameter name. It stays `src1` no matter what source you select (price, indicator, or constant).
You can’t change the number — `src2` or other variants don’t exist.</Note>
