550是什么意思？

550是网络用语，我吻你的意思。
网络语言是指从网络中产生或应用于网络交流的一种语言，包括中英文字母、标点、符号、拼音、图标（图片）和文字等多种组合。这种组合，往往在特定的网络媒介传播中表达特殊的意义。
20世纪90年代诞生初，网民们为了提高网上聊天的效率或诙谐、逗乐等特定需要而采取的方式，久而久之就形成特定语言了。进入21世纪的十多年来，随着互联网技术的革新，这种语言形式在互联网媒介的传播中有了极快的发展。




网络用语的发展：
如果留意和总结一下近些年人们在表示愤怒时常说的词语，就会发现一条清晰的演化路线。即从最初由港台引进的“哇噻”（尽管后来在国内它大多代表惊喜的意思，但起初这却是句骂人的话）。我倒（现多用这个字面上比较文明的形式），我晕，我笑。
中间的那几个都被人们从起初的接受到后来的放弃，这是一个人民群众在语言使用过程中选择的过程，那些不符合时代和社会发展的词语最终会被抛弃在历史的长河之中，而只有那些被大多数人所认可的才会有持久的生命力。
针对互联网网络用语泛滥的情况，要抵制粗鄙、低俗的网络语言。

lmax的mtf与ecn有什么区别？

What's the difference between an MTF and an ECN?

MTFs (Multilateral Trading Facilities) are a MIFID Europe concept, defined as 'a multilateral system, operated by an investment firm or a market operator, which brings together multiple third-party buying and selling interests in financial instruments - in the system and in accordance with non-discretionary rules - in a way that results in a contract in accordance with the provisions of Title II of MiFID.'

This broadly fits with the SEC's definition of an exhange, which is 'any organization, association, or group of persons that:(1) brings together the orders of multiple buyers and sellers; and (2) uses established, non-discretionary methods (whether by providing a trading facility or by setting rules) under which such orders interact with each other, and the buyers and sellers entering such orders agree to the terms of a trade.', and some business such as BATS are listed regulated as an MTF in Europe and an Exchange in the USA.

Having said that, you'll find a lot of literature that consider and ECN and an MTF to be equivalent.

So what's the practical difference?

LMAX runs a single order book with binding orders. There's no last look by price providers, no opporunity to re-quote, and no routing around a network of possible counterparties to find a price. As a result a customers ability to hit an advertised price is only constrained by competition and the laws of physics, offering reliable and consistent order execution.

There's nothing to stop an ECN from operating in the exactly same way as LMAX, but many ECNs do offer price routing, last look etc, adding a degree of unpredictability to order execution. The regulatory constraints on an ECN are also less clear because it depends on what exemptions they've agreed and what level of market share they've acquired. There's much less negotiation around the regulatory requirements for an MTF.以上内容摘自投机修真记。
