论坛有个大佬写了单策略多合约，我有些想法 ，我现在是单合约多策略，但是总感觉之前那位大佬，写的多合约直接这样循环有问题，会堵塞吧？？然后TQ又不能调用多进程，多线程不安全，多合约同一策略确实是个大问题。。
while True:
# print('主循环启动')
tq_api.wait_update()
#tq_api.is_changing(qtick)
#print('最新 ：',qtick.last_price)
#print('买一：',qtick.bid_price1)
#print('卖一：',qtick.ask_price1)
# 多合约运行的话，需要循环检测哪个合约的行情产生了变化，进行处理
for symbol in list_code:
if tq_api.is_changing(kLineDic[symbol]):
