# Stock Runway and Lead Time
## Stock Runway
Stock Runway shows how many days your current stock is expected to last based on the forecast. It highlights products that are likely to run out in the coming days.
When Stock Runway is active, the forecast cells are colour coded:
* **Green** — stock is sufficient to cover that day's expected demand
* **Yellow** -- stock is getting low
* **Red** — stock is expected to run out before or on that day
## Lead Time
When Lead Time is active, it factors in approximate delivery times when showing to give users insight how soon you need to order.
### Updating Lead Time on Stock Item
1. In the [**Admin Portal**](https://admin.gobossit.com/), go to the **group level**.
2. Navigate to **Stock > Items**.
3. Locate and click on the relevant stock item.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.bossithq.com/stock/demand-forecast/stock-runway-and-lead-time.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
