Whats the command in the console please?
Do you mean the command to cancel an order?
wallet_market_cancel_order <order_id>
to get the order ID:
wallet_market_order_list <base_symbol> <quote_symbol> [limit] [account_name]
this will be
wallet_market_order_list USD BTSX //for your bitUSD orders
[edit] order id might need to be in quotes.
