I doubt there is a proper way to cancel all listings in a loop as the server needs to respond on the cancel in between.

The confirmation dialog is called via function
TRADING_HOUSE:ShowCancelListingConfirmation(listingIndex)

function ZO_TradingHouseManager:ShowCancelListingConfirmation(listingIndex)
    if not self.cancelListingDialog then
        self.cancelListingDialog = ZO_TradingHouseCancelListingDialog
        CancelListingDialogInitialize(self.cancelListingDialog, self)
    end

    self.cancelListingDialog.listingIndex = listingIndex
    ZO_Dialogs_ShowDialog("CONFIRM_TRADING_HOUSE_CANCEL_LISTING")
end

One maybe able to prehook it and return true to suppress it that way, and automatically call teh API function
CancelTradingHouseListing(listingIndex)

I'll see if this is possible and works and add it to my addon
FCOChangeStuff then.

Will post here once I found the time to test and add, if possible.

I'll add this to my swiss knive addon "FCOChangeStuff" and release it with version 0.2.6

You'll find it at Minion too.

Omg, you're a beautiful person! Thank you so much! All this stuff goes totally over my head so im so pleased you could figure out how to make this work, very excited for version 0.2.6!
