这个策略基于不同周期的EMA均线的交叉来判断趋势方向,并据此建立做多做空信号。主要使用2条均线,分别是10日线和20日线。当10日线从上向下穿过20日线时,做空;当10日线从下向上穿过20日线时,做多。该策略属于中短线交易策略。
该策略使用了2条EMA均线,包括10日线和20日线。EMA均线能很好地反映价格的趋势方向。当短期EMA线从下向上穿过长期EMA线时,表示价格走势由跌转升,属于做多信号;当短期EMA线从上向下穿过长期EMA线时,表示价格走势由升转跌,属于做空信号。
该策略同时结合了波动的极大值和极小值来过滤一部分交易信号。只有在价格波动达到一定幅度后,才会发出交易信号。这可以一定程度上过滤掉部分假信号。
具体来说,该策略通过追踪价格的极大值和极小值的到达时间,来判断价格趋势是否形成。在极大值或者极小值达到一定时间后,才会发出真正的交易信号。
该策略具有以下几个优势:
该策略也存在一些风险:
可以通过以下方法降低风险:
该策略可以从以下几个方向进行进一步优化:
该EMA交叉策略整体来说是一种简单实用的趋势跟踪策略。它使用EMA均线判断大趋势方向,再结合价格波动过滤信号,形成交易决策。该策略易于理解和调整参数,可以适应中短线交易。通过进一步优化,这可以成为一种值得长期持有使用的量化策略。
