Dear API user,

HTX is going to support batch cancellation upon multiple symbol selections, in existing batch order cancellation endpoint in REST API.

Effective Date：Sep 2, 2019 （GMT+8）
All the changes will be updated on https://huobiapi.github.io/docs/spot/v1/en/

The following are change details：
The existing REST API endpoint ”POST /v1/order/orders/batchCancelOpenOrders” does support open order cancellation upon a specific symbol.
Or, if user didn’t specify the symbol, the endpoint does cancel all the open orders (if any) upon all available symbols.
Since the effective day of this notification, HTX will be allowing users to specify multiple symbols (maximum 10 symbols in a request,
separated by comma) in existing query field “symbol”, while cancelling orders in batch mode via this endpoint.
There will be no change to other query fields, e.g. the maximum number of orders in one batch is still 100, neither response fields.

HTX
