该策略结合布林带和移动平均线,设计了一个跟踪趋势的交易系统。当价格突破布林带上轨且低轨高于SMA200时做多,当价格跌破布林带下轨时部分平仓,当价格跌破SMA200时全部平仓。该策略追踪趋势,在趋势变化时及时止损。
该策略判断趋势存在的前提是布林带需要完全位于SMA200之上,只有在明确的上升趋势中才会选择多头方向入场。当下跌趋势来临时,通过关键点份额止损和全仓止损来控制风险。
可以通过仔细测试布林带参数,优化部分止损策略,调整SMA周期参数,并引入更科学的风险管理方法来降低这些风险。
该策略整合布林带通道、SMA均线指标设计了一个较完整的趋势跟踪策略。它在判断趋势存在时比较可靠,具有较强的趋势跟踪能力。通过持续优化止损策略、降低信号误判率、引入科学的风险管理手段,该策略可以成为一个值得长期实盘跟踪的趋势策略。它为量化交易策略设计提供了一个整合多个指标的思路。
