骨刀 麻烦梦神给稍微讲解一下在主函数中的引用方法吧。 例如 给举个例子 在30000的价格开仓 BTC_USDT quarter做多合约1张，应该怎么写呀？ 活着给讲解一下主函数中 var info = $.OpenLong(exchange, "quarter", 100) 这是开季度合约的多仓吧？那么exchange，100分别代表什么呀？
高吸低抛 SlidePrice最好应该是价格比率吧
小小梦 $.OpenLong(exchange, "quarter", 100) 就是在exchange这个交易所对象，开多，季度合约，100张。
小小梦 高频建议单独写交易机制，这个类库有一些交易剩余量检测，会很耗时。高频了建议直接定制交易逻辑了。
高吸低抛 我用这个OpenLong DOT（4刀），给我用9刀下单(4+5) .这个类里Sleep()时间太长，高频用不了，等我改改：）
小小梦 不是，是滑价，就是吃单时多出的一点溢价。
