# FlashingCellType

Canonical page: https://www.adaptabletools.com/docs/reference/flashingcelltype

Flashing Cell rule flavour: Change (this edit vs previous value, including
any / percent / absolute change and value comparisons) or Observable
(live history over time — `CHANGE_COUNT`, `PREVIOUS`, …).

```ts title="TypeScript"
export type FlashingCellType = 'Change' | 'Observable';
```
