该策略基于布林带(Bollinger Bands)指标,通过价格突破布林带上下轨的方式产生交易信号。当价格突破上轨时做多,突破下轨时做空。同时,当持有多单时,如果价格跌破下轨则平多;持有空单时,如果价格突破上轨则平空。该策略旨在捕捉市场的波动性,在价格波动加剧时及时入场交易,并在价格反转时及时止损。
BB均线突破策略是一个基于布林带指标的交易策略,通过捕捉价格突破布林带上下轨的机会进行交易。该策略优点是信号明确,易于实现,同时具有一定的风险控制措施。但是该策略也存在一些局限性,如交易频率可能过高,信号滞后等问题。因此在实际应用中,可以考虑从信号确认、止损优化、参数优化等方面对策略进行改进,以提高策略的稳定性和盈利能力。
