This WebSocket message is used to subscribe to large trade transactions filtered by specified volume thresholds in USD.

**Key Notes:**

* Only swap transactions are included.
* The `min_volume` parameter is **mandatory** and sets the lower bound for the trade volume in USD, the min allowable set is `0`.
* The `max_volume` parameter is **optional** but must be higher than `min_volume` when provided.
* Transactions outside the specified volume range will be excluded from the subscription.
* The response includes trades for all tokens that meet the volume criteria, regardless of token type or trading pair.
