概述
本策略针对现货交易平台BitMEX设计,通过对快速RSI指标进行分析,结合多项技术指标筛选信号,实现高效率的趋势追踪交易。策略同时设置了资金管理、止损机制,可以有效控制交易风险。
策略原理
计算快速RSI,参数设置为7日线,超买线25,超卖线75。当RSI上穿超买线,为超买信号;当RSI下穿超卖线,为超卖信号。
对K线实体设置筛选。要求开盘为阴线,实体长度不小于昨日平均实体20%。
对K线颜色设置筛选。要求最近4根K为阴线时做空,最近4根K为阳线时做多。
设置止损逻辑。当价格向不利方向移动时,平仓止损。
设置防反弹机制。当价格向有利方向移动达到止损线时,再次发出信号才建仓。
设置资金管理。采用固定资金百分比建仓,每损失一笔加倍仓位。
优势分析
快速RSI参数设置合理,能快速捕捉趋势。结合K线实体和颜色判断,可有效过滤假突破。
多层过滤信号,可以减少交易次数,提高胜率。
策略内置止损机制,可以有效控制单笔损失。
采用动态仓位调整,实现适度激进的资金管理。
可自定义交易时间段,避开重大事件带来的震荡。
风险及优化
速度过快可能漏掉交易机会。可以适当放宽参数,增加灵活性。
无法有效判断趋势末期。可考虑结合其他指标判断潜在反转。
仓位调整方式过于激进,可引入锁仓方式。
可根据不同市场调整参数,实现更优的参数组合。
总结
本策略整体来说较为稳健,通过快速RSI判断趋势方向,再结合多重技术指标过滤信号,可以在趋势中获得较好回报。同时策略具备一定的优化空间,通过调整参数组合,可适应不同市场环境,具有较强的实用性。
