撮合引擎

成交价

CoinAll撮合系统撮合订单的优先级按照价格优于时间的优先级来撮合，优先撮合价格更有优势的订单。当价格一致时按照下单时间顺序撮合，先下单的先撮合。 比如深度列表中目前有3笔挂单等待成交，分别为1: 9900USDT买1BTC，2: 10100USDT买2BTC，3: 9900USDT买1.5BTC。他们是按时间顺序1-2-3进入撮合系统的，根据价格优先，系统优先撮合订单2，根据时间优先，1跟3优先撮合1。所以系统撮合顺序是2-1-3。

YubiKey 4 series GPG and SSH setup guide

Written for fairly adept technical users, preferably of Debian GNU/Linux, not for absolute beginners.

You'll probably be working with a single smartcard, so you'll want only one primary key (1. Sign & Certify) and two associated subkeys (2. Encrypt, 3. Authenticate). I've published a Bash function which automates this slightly special key generation process.
