本文提供了一个用vn.py来编写R-breaker交易策略的示例。只提供一个参考模板,并不能直接进入市场进行交易。感谢‘爱谁谁’在维恩的派论坛里的分享!...策略介绍 R-breaker策略是一种短线交易策略,结合了趋势和反转两种交易方式。 策略逻辑 周期:1min、5min 1....R-Breaker 是日内交易策略,若某个交易日已开仓且收盘前仍未触发平仓信号,则在收盘时强行平仓,不隔夜留仓以避免跳空的风险。...参考文献: R-Breaker 策略优化表现 (http://www.sohu.com/a/120307567_505915) 点击“阅读原文”查看原贴!
今天我们分享的内容是在spring下的三种circuit breaker的做法。...今天我们说的是circuit breaker,所以这里我们也不会去配置/error这个mapping。 接下来我们就开始circuit breaker之旅吧。...好,我们现在已经知道了hystrix的circuit breaker的基本使用了。 但现在你还并不知道hystrix的一些内部的监控信息。你也许发现了,我们之前引入了actuator的依赖。...这种做法虽然不像是一个正宗的circuit breaker。...但指定次数retry后,最后跳转到fallback方法,也算是一种最后对所执行的方法的一种解救,从而不至于所有的请求卡死排队在这里造成雪崩效应,从这个角度上,spring retry也算是一种circuit breaker

R-Breaker是个经典的具有长生命周期的日内模型 类型:日内趋势追踪+反转策略 周期:1分钟、5分钟 根据前一个交易日的收盘价、最高价和最低价数据通过一定方式计算出六个价位, 从大到小依次为: 突破买入价
