关于比特币套利交易的文章,坊间一搜一大堆,尤以 2014,2015 为甚。那时交易所间价差相当可观,套利的机会很多,躺着赚钱并非难事。如今,套利区间收窄,留在沙场上的估计只剩下大玩家,想要不费力气躺赢机会渺茫。最近帮朋友牵线寻找币圈量化交易的机会,本欲做个打酱油的中间人,事了拂衣去,安安静静做个三河市微胖界扛把子,谁料还是一时技痒,不小心昨夜搭进去六七个小时。
关于如何做套利交易,我就不赘述,大家可以看这篇文章,有内容有故事:https://daily.zhihu.com/story/4831821。
本文没有故事,只有技术和产品上的分析。
既然要做可行性分析,那么第一步就是观察交易数据。国内的交易市场虽然在政策要求下清场出局,国外的交易市场还算红火。从 bitfinex,kraken 一路到 bithumb,korbit 等,都提供 rest API,少量提供 websocket 接口。虽然文档欠缺,但这些接口都很简单,上手并不困难。
