使用TargetPosTask 下单

while True:
    api.wait_update()
    if api.is_changing(ru2101) or api.is_changing(ru2105):
        spread = ru2105.ask_price1 – ru2101.bid_price1
        print(“当前价差:”, spread)
        if spread < -200:
            print(“目标持仓: 空近月，多远月”)
            # 设置目标持仓为正数表示多头，负数表示空头，0表示空仓
            target_pos_near.set_target_volume(-1)
            target_pos_deferred.set_target_volume(1)
        if spread >200:
            print(“目标持仓: 空仓”)
            target_pos_near.set_target_volume(0)
            target_pos_deferred.set_target_volume(0)

抄的例子的这个代码，怎么执行完，成交不了？
