Trading account and WebSocket
- Added
GET /api/v5/account/position-tiersto fetch position and leverage tier information per instrument family. - The private
positionsWebSocket channel now emitspTime(push timestamp) distinct fromuTime(data update timestamp) so consumers can measure delivery latency.
Deprecation. The legacy POST /api/v5/account/set-greeks endpoint is
deprecated in favor of the greeksType parameter on
POST /api/v5/account/set-account-level. The legacy endpoint will be removed in
a future release; migrate to the account-level setting.
