前日看vnpy更新了，非常感谢作者大神更新了下我上次发帖提的ctp二代行情的接口。有个问题想请教下：
if data["BidPrice2"]:
tick.bid_price_2 = data["BidPrice2"]
tick.bid_price_3 = data["BidPrice3"]
tick.bid_price_4 = data["BidPrice4"]
tick.bid_price_5 = data["BidPrice5"]
tick.ask_price_2 = data["AskPrice2"]
tick.ask_price_3 = data["AskPrice3"]
tick.ask_price_4 = data["AskPrice4"]
tick.ask_price_5 = data["AskPrice5"]
tick.bid_volume_2 = data["BidVolume2"]
tick.bid_volume_3 = data["BidVolume3"]
tick.bid_volume_4 = data["BidVolume4"]
tick.bid_volume_5 = data["BidVolume5"]
tick.ask_volume_2 = data["AskVolume2"]
tick.ask_volume_3 = data["AskVolume3"]
tick.ask_volume_4 = data["AskVolume4"]
tick.ask_volume_5 = data["AskVolume5"]
我看代码里这段似乎是只有当bp2>0时才会赋值五档行情，但行情有时会出现跌停的情况，导致bp2==0，此时ap这边是有五档的，这样处理是否会导致跌停的时候只有一档行情呢？我感觉可以data["BidPrice2"]和data["AskPrice2"]分别判断，来赋值。希望作者大神看下，谢谢。
