我一直在尝试使用4小时的间隔来获取特定对的最后几个月的历史数据。我被引导到以下格式来获取数据：
https://poloniex.com/public?command=returnOrderBook¤cyPair=BTC_ETH
但有没有办法可以使用这些链接指定持续时间和时间间隔？
以上链接仅返回非常少量的数据：

Poloniex API文档非常缺乏。对于订单簿条目，您可以指定深度：
https://poloniex.com/public?command=returnOrderBook¤cyPair=BTC_NXT的＆安培;深度= 100
通过这种方式，您可以获得更多或更少的出价和询问条目。
从我可以收集的内容（来自他们的支持页面和论坛），您无法指定这些订单何时下达的时间范围。此命令显示特定时刻的所有活动订单。通过使用他们的websocket，您还可以获得订单簿的实时订阅源。

<强> returnOrderBook
返回给定市场的订单簿，以及用于Push API的序列号和指示市场是否冻结的指标。您可以将currencyPair设置为＆＃34; all＆＃34;获得所有市场的订单。样本输出：
{＆＃34;问＆＃34;：[[0.00007600,1164]，[0.00007620,1300]，...]，＆＃34;出价＆＃34;：[[0.00006901,200]，[0.00006900， 408]，...]，＆＃34; isFrozen＆＃34;：0，＆＃34; seq＆＃34;：18849}
或者，对于所有市场：
{＆＃34; BTC_NXT＆＃34;：{＆＃34;问＆＃34;：[[0.00007600,1164]，[0.00007620,1300]，...]，＆＃34;出价＆＃34;： [[0.00006901,200]，[0.00006900,408]，...]，＆＃34; isFrozen＆＃34;：0，＆＃34; seq＆＃34;：149}，＆＃34; BTC_XMR＆＃34;： ...}
致电：https://poloniex.com/public?command=returnOrderBook¤cyPair=BTC_NXT&depth=10
因此（正如弗洛林亚历山德鲁已经提到的那样）你需要添加“深度”＆＃39;查询参数。
数据包含要求和出价的元组。第一个数字是此条目的价格，第二个是该条目的销售/购买的（最大）金额。
如果您不需要实际优惠，我建议使用returnChartData：
<强> returnChartData
返回烛台图表数据。所需的GET参数是＆＃34; currencyPair＆＃34;，＆＃34; period＆＃34; （烛台时间以秒为单位;有效值为300,900,1800,7200,14400和86400），＆＃34;开始＆＃34;和＆＃34;结束＆＃34;。 ＆＃34;开始＆＃34;和＆＃34;结束＆＃34;以UNIX时间戳格式给出，用于指定返回数据的日期范围。样本输出：
[{＆＃34;日期＆＃34;：1405699200，＆＃34;高＆＃34;：0.0045388，＆＃34;低＆＃34;：0.00403001，＆＃34;开＆＃34;：0.00404545，＆ ＃34;靠近＆＃34;：0.00427592，＆＃34;体积＆＃34;：44.11655644， ＆＃34; quoteVolume＆＃34;：10259.29079097，＆＃34; weightedAverage＆＃34;：0.00430015}，...]
