tdaapi尾部停止在放置时失败

Question

总结： 当我从TDAAPI在python中放置一个拖尾停止顺序时，它给出了错误

"error": "trailingStopMethod is required when orderType is Trailing Stop."

当我创建一个保存的订单（通过将place\u order更改为create\u saved\u order）并手动放置它时，没有任何问题。从下面的调用中，我相信我通过执行set_stop_price_link_type(StopPriceLinkType.VALUE)来指定trailingstop方法，以指定我正在执行值偏移。以下是订购规格

from tda.orders.common import OrderType, StopPriceLinkType
from tda.orders.common import Duration, Session

trailStopResponse = client.place_order(config.account_id,
                            equity_sell_market(symbol,qty)
                            .set_duration(Duration.DAY)
                            .set_session(Session.NORMAL)
                            .set_order_type(OrderType.TRAILING_STOP)
                            .set_stop_price_offset(atrValFifteen/3) #trailing the market with our ATR val
                            .set_stop_price_link_type(StopPriceLinkType.VALUE) #-> means we're supplying a price as a stop value
                            .build()
                )

让我知道我错过了什么，使这个电话工作时，由自己放置
