Freezed open orders

I’m trying to test my application using Exchange/PRO api on sandbox environment.

Whenever I request my orders via endpoint (with statuses open, pending, active), I receive list of orders.

“client_oid”: “<client_order_id>”,
“created_at”: “2023-05-03T16:31:55.011071Z”,
“executed_value”: “0.0000000000000000”,
“fill_fees”: “0.0000000000000000”,
“filled_size”: “0.00000000”,
“id”: “d69a6eec-ddc7-413f-9f78-50c352ecce91”,
“market_type”: “spot”,
“post_only”: false,
“price”: “450000.00000000”,
“product_id”: “BTC-USD”,
“profile_id”: “<profile_id>”,
“settled”: false,
“side”: “sell”,
“size”: “0.00000223”,
“status”: “open”,
“time_in_force”: “GTC”,
“type”: “limit”

But it looks like some of orders returned by /orders endpoint are not active. I can’t cancel them neither via FIX nor HTTP request.
FIX Order Cancel Request returns message with FIX tags: 35=9 58=order not open.
And HTTP request for cancel all orders (with profile_id and product_id of freezed orders) returns empty json array.

How could I cancel these orders?

Hi @saddwarf ,

Thank you for your contact us, we are happy to help you.

I understand that you are facing some issue with your Exchange/pro orders cancellation.

We are not supporting Exchange/pro anymore, instead we suggest you to use Advance trade API.

Hence we request you to use advance trade API and if you are facing any issue with that please don’t hesitate to contact us, we will help you.
