Request Parameters

Parameters	Type	Required	Description
op	STRING	Yes	cancelorders
tag	INTEGER or STRING	No	If given it will be echoed in the reply and the max size of tag is 32
dataArray	LIST of dictionaries	Yes	A list of orders with each order in JSON format, the same format/parameters as the request for cancelling a single order. The max number of orders is still limited by the message length validation so by default up to 20 orders can be placed in a batch, assuming that each order JSON has 200 characters.
