# How to Get Fade Float and Percentage Price History

> cs2.sh exposes BUFF `float_fade` buckets that price an exact float range and Fade percentage range together, with OHLC history from May 19, 2026.

Float and Fade premiums overlap. Adding a float-only premium to a Fade-only premium double-counts listings that can belong to both groups. The combined bucket is the direct market slice for both attributes.

## BUFF range combinations

`GET /v1/market/buff/latest` splits a Fade item into available `base`, `float`, `fade`, and `float_fade` buckets.

| Bucket | Population |
| --- | --- |
| `base` | Entire item or variant |
| `float` | One float range |
| `fade` | One Fade percentage range |
| `float_fade` | Listings matching both ranges |

Each range uses an inclusive `min` and exclusive `max`. `bucket_id` stays stable between latest and history. Current buckets contain `ask`, `avg_ask`, `bid`, `ask_volume`, and `bid_volume` and refresh every 10 minutes.

## Select and compare history

Fetch the latest BUFF snapshot and choose the single `float_fade` bucket whose float and Fade bounds contain the item attributes. Retain its matching `base`, `float`, and `fade` buckets when available.

Request the same `market_hash_name` on `POST /v1/market/buff/history` and join series by `bucket_id`. Compare closing asks at shared timestamps. The combined-to-float comparison isolates the observed Fade difference within a similar float range; combined-to-fade isolates the float difference within a similar Fade range.

History provides ask, average-ask, and bid OHLC at `30m`, `1h`, or `1d`. It starts May 19, 2026 and requires Scale or Enterprise access.

## Applicable endpoints

| Endpoint | Returns | Plans |
| --- | --- | --- |
| `GET /v1/market/buff/latest` | Current base, float, Fade, and combined buckets | All plans |
| `POST /v1/market/buff/history` | Per-bucket OHLC since May 19, 2026 | Scale, Enterprise |

## What changes the comparison

- Not every item has every one-dimensional or combined bucket. Missing slices must remain unavailable.
- Discover ranges from the response. Common float bands are not a contract for every item.
- A bucket `close_ask` is the last listing floor, not a completed sale or an exact appraisal.
- Thin `ask_volume` allows one listing to move the floor substantially.
- Compare only shared timestamps. Forward-filling one side can create a premium that was never observed concurrently.
