batch cancellations

1

Are there batch cancellations like dm.send_contract_batchorder extending usage of dm.send_contract_order?Or can one apply filter for direction and offset in cancel_all_contract_order?  dm.cancel_all_contract_order(symbol='BTC')   Best regards, Ingyu

dm.get_contract_depth() dm.get_contract_kline()等核心功能无法使用 怀疑跟网站更新有关?
