运行出错信息，不理解，请教

错误信息：

Traceback (most recent call last):
File “c:/TianQin/strategies/AB振埋单Y.py”, line 572, in <module>
B2 = api.insert_order(symbol=SYMBOL1, direction=”SELL”, offset=”CLOSETODAY”,limit_price=Bid1, volume=lots, advance=”FAK”)
TypeError: insert_order() got an unexpected keyword argument ‘advance’

为什么出现意外参数？
