如果有交易成交发送邮件，请问这个过程需要在run.py中加入什么操作吗/还是只要在策略中使用self.send_email()就可以？？？
def main():
"""Start Veighna Trader"""
qapp = create_qapp()
event_engine = EventEngine()
main_engine = MainEngine(event_engine)
main_engine.add_gateway(CtpGateway)
main_engine.add_app(CtaStrategyApp)
main_engine.add_app(CtaBacktesterApp)
#main_engine.add_app(DataManagerApp)
main_window = MainWindow(main_engine, event_engine)
main_window.showMaximized()
qapp.exec()
if name == "main":
main()
