vnpy 2.1.1
比如这段简单到代码:
from vnpy.app.script_trader import init_cli_trading
engine = init_cli_trading([CtpGateway])
engine.connect_gateway(setting, "CTP")
time.sleep(8)
vt_symbol = 'rb2310.SHFE'
inprice_b = 3900
close_pos = 1
order = engine.buy(vt_symbol, inprice_b, abs(close_pos))
早上8点56的时候，不会发送订单， 9点之后buy就能正常发出订单，请问是哪里写错了吗
