币安现货测试网API返回价格冻结问题咨询

各位好，我正在用Python开发基于Binance API的交易机器人，之前在测试网一直运行正常，但从昨天开始，订单簿（orderbook）和行情ticker的API突然返回冻结的价格了。我不是Binance的直接客户，没法直接联系官方确认这个问题，所以来这里问问有没有其他开发者遇到同样的情况——我查了Binance官网也没看到相关公告。如果这是普遍存在的问题，我就联系我的客户（我用的是他的账户），让他去联系Binance处理。

先跟大家说明下正常情况：LTC的买卖价格（bid/ask）正常来说每5-10秒至少会有0.01的波动，而且据我了解Binance测试网的价格应该和实盘保持接近，不会出现长时间不动的情况。

测试网异常日志 #

下面是我截取的一段日志，可以看到价格完全冻结了：订单簿的bid固定在64.18、ask固定在64.1，而ticker的bid固定在64.1、ask固定在64.18，两者各自保持不变，完全没有波动：

提前说明排除的可能性 #

有人可能会说是不是测试网没有匹配订单导致价格不动，但我可以提前排除这个：Binance是大型交易所，哪怕测试网也应该有足够的订单来维持价格波动；而且我从可靠渠道了解到，测试网的价格应该和实盘保持接近，所以肯定是会有变动的。

实盘测试结果 #

我用同样的代码在现货实盘运行，价格完全正常波动，以下是实盘的日志片段：

核心代码片段 #

我的代码逻辑很简单，就是循环获取订单簿和ticker数据，打印价格后休眠，核心代码如下：

while(True):
    order_book = client.get_order_book(symbol=symbol)
    new_bid = float(order_book['asks'][0][0])
    new_ask = float(order_book['bids'][0][0])
    logging.info(f" From orderbook:  ####")
    logging.info(f" ---------New bid: {new_bid}, new ask:{new_ask}  ####")

    ticker = client.get_orderbook_ticker(symbol=symbol)
    new_bid = float(ticker['bidPrice'])
    new_ask = float(ticker['askPrice'])
    logging.info(f" From Ticker:  ####")
    logging.info(f" ---------New bid: {new_bid}, new ask:{new_ask}  ####")

    logging.info(f"Wait for {pause_time} seconds")
    time.sleep(pause_time)

麻烦各位如果遇到同样的问题，或者知道是什么原因的话，帮忙回复一下，非常感谢！
