昨天发了一篇文章，《一起来玩内部市场吧！/ Let's play the internal market》
很多朋友私下里表示了极大的兴趣，因为内部市场最吸引人的特点：没有手续费！与其去其它各类市场被人家薅羊毛，不如咱们自己在内部市场愉快的玩耍，没有手续费，考验的就是技术和运气了。
关于内部市场，我之前也写过一系列的文章，当然其实就是自己学习的过程，毕竟在这之前，我对交易什么的也一窍不通。详情可参考页面底部的之前相关文章。在这篇文章中，我来介绍一下，自动操作可能涉及到的API等。

本篇文章介绍以下API / In this article, I'll introduce the following APIs by example:
- get_ticker()
- get_volume()
- get_order_book()
- get_recent_trades()
- get_trade_history()
- get_market_history_buckets()
- get_market_history()
详情可以参考，market_history_api.hpp
They are located in market_history_api.hpp
API返回的结果是JSON 编码字符串，为了便于查看，我将其解码并格式化显示。
The return results are JSON encoded string, For convenience, I decode them and display them formatted.
