# Quote Cancel(Z)

The `Quote Cancel` (`Z`) message is used by an originator of quotes to cancel his quotes and related orders.

The Quote Cancel message supports cancelation of:

* All quotes
* Quotes for a specific symbol
* All quotes for a security kind (like futures, options)
* By QuoteSetID
* By base Currency of the instruments
* By Delta range

The canceling is accomplished by indicating the type of cancelation in the `QuoteCancelType` (`298`) field and optional additional parameters.

The message is equivalent of the `private/cancel_quotes` and shares the same semantic, so it is quite different from the other exchanges. The same as the Websockets "alter-ego" it is acknowledged only via list (possibly empty) of cancelled orders, namely as the `Order Mass Cancel Report` (`r`) with `ClOrdID` equal to the `QuoteMsgID` of the request, with the affected order ID's and subsequent `Execution Report` (`8`)-s for each individual cancelled order if there are any.
