关于北京时间 2019 年 5 月 31 日凌晨的 Websocket 延迟

在北京时间 2019 年 5 月 31 日凌晨 00:00-01:00,由于市场波动,BitMEX 的 websocket API 受到持续的延迟,其延迟是来自交易引擎产生的流量飙升。期间,websocket 连接亦一度无法持续更新市场数据,这是因为当时已达到内部通信层的内存限制,导致重新连接。

我们的工程师已加紧发展我们已计划的战略升级来优化我们的市场数据分布式架构,将大幅提高容量和减低 websocket 源的整体延迟。该容量升级预计于本周在 Testnet 上部署,在主网更新后我们会有公告通知各位。

Websocket Latency, 30 May 2019

Between 16:00 and 17:00 UTC 30 May 2019 the websocket API experienced periods of substantial lag due to spikes of traffic generated by the trading engine during large market moves. During this period some websocket connections also experienced dropped market data updates as memory limits on an internal messaging layer were hit, forcing reconnections.

Our engineers are accelerating the development effort in an already-planned strategic upgrade of our market data distribution architecture to vastly increase its capacity and lower the overall latency of the websocket feed. This capacity upgrade is scheduled for Testnet release this week and we will update users once this has been released to the main platform.

If you have any further questions, please contact Support via our contact form: https://www.bitmex.com/app/support/contact.

关于徽标的更新

我们很高兴地为 BitMEX 的视觉识别进行更新。从今天开始,你将看到这个替换徽标应用在所有 BitMEX 的产权里。关于我们徽标的历史背景,以及此更新的构想,请继续阅读。

我们的历史

BitMEX 徽标是在 2014 年初,在初始交易平台推出之前创建的,代表了 “买卖权平价关系”。买卖权平价关系定义了期货合约(或更简单地说,远期合约),可以通过由做多看涨期权和做空看空期权的投资组合来复制的。

最初的徽标设计是对于买卖权平价公式的阐述,虽然有效,但在很多现实环境里却不太实用。时移世易,我们已经减少了图示和徽标意象的表达,而增加了它的灵活性,以便更容易在社交媒体,合约以及一切运营一个现代化交易平台所使用的。

下一步是什么

随著我们不断改进 BitMEX 交易体验,我们也将会改善平台的外观和感觉,以便为你提供所需的所有信息,使你能够在一个简洁易明和专业的交易平台上作出明智和果断的交易。

我们重视过去几年我们收到的所有支持和反馈,请继续通过我们的微博支持页面来让我们知道该如何继续改进。

Logo Update

We are pleased to introduce updates to the BitMEX visual identity. Starting today, you will see the replacement marks applied to all BitMEX properties. For some background on the history of our logo, as well as the construction of the update, please read on.

Our History

The BitMEX logo was created in early 2014 before the launch of the initial trading platform and is a representation of the ‘put-call parity’. The put-call parity defines that a futures contract (or more simply, a forward) can be replicated by a portfolio consisting of a long call option and a short put option.

The original logo design was a literal interpretation of the put-call parity formula, which, while effective, proved unwieldy when applied to a myriad of real-world scenarios. Over time, we have made the icon and logo less representational, and more flexible, to allow for easier use in social media, contracts, and everything in between that comes with running a modern trading platform.

What’s Next

As we continue to improve the BitMEX trading experience, we will also be improving the look and feel of the platform so as to give you all the information you need to make intelligent, decisive trades on a clean, easy-to-read, and professional platform.

We value all the support and feedback we have received over the past few years, please continue to let us know how we can continue to improve, on Twitter, and through our support page.
