Cancel a Delta Order

To cancel orders, you can use the /cancel endpoint provided by the API, which would remove the orders from the order book. The signature is an EIP-712 signature, built with the following structure. Both LIMIT and MARKET orders can be canceled.

domain	{ "name": "Portikus", "version": "2.0.0", "chainId": <chainId>, "verifyingContract": <deltaAddress> }
type	{ "OrderCancellations": [ { "name": "orderIds", "type": "string[]", } ] }
value	{ "orderIds": [<id1>, <id2>] }
