# Crypto 2b exposure direction

> Reference for the Crypto 2b Exposure Direction dimension, a Copper analysis hierarchy classifying each Crypto 2b underlying as Long or Short based on its net aggregated gross exposure.

The **Crypto 2b Exposure Direction** hierarchy classifies each Crypto 2b underlying as Long or Short based on the relative size of its aggregated gross exposures.

| | |
| - | - |
| **Description** | Derived direction of each Crypto 2b underlying, classifying it as Long or Short based on which gross side dominates at query time. |
| **Members** | Long, Short |

This is a Copper analysis hierarchy derived at query time. For each underlying, the absolute long exposure (`Crypto 2b Exposure Long`) and absolute short exposure (`Crypto 2b Exposure Short`) are compared:

* **Long** — when the absolute long side is greater than or equal to the absolute short side.
* **Short** — when the absolute short side is greater.

Underlyings with no exposure on either side produce a null member and are excluded.

**Difference from [Crypto 2b Direction](./risk#crypto-2b-direction):** `Crypto 2b Direction` is a stored level sourced from the input data, reflecting the raw per-sensitivity direction field. `Crypto 2b Exposure Direction` is computed at query time across all sensitivities of an underlying and reflects the net directional classification of the aggregated exposure.
