Python Interactive Brokers API 对于历史期权价格非常慢

Question

在下面的代码中，我试图检索一些期权价格的历史价格。我正在查看 4 个月的历史，条形大小为 8 小时。我以 Apple 为例，我正在尝试下载 6 次行使价和一次到期的看涨期权价格。这需要疯狂的时间......

当我运行下面的代码时，第 1 次打击需要 20 秒，第 2 次打击需要 1770 秒，第 3 次打击需要 3400 秒，第 4 次打击需要 840 秒，第 5 次打击需要 560 秒最后一击还有 460 秒。下载所有内容大约需要 2 个小时。出了什么问题，我该怎么做才能让它更快？

Answer 1

用“TRADES”代替“ASK”是可行的。 IT 需要 20 秒，而不是之前的 2 小时。
