SR Breakout Strategy是一个基于LonesomeTheBlue的breakout finder指标开发的支撑阻力突破策略。该策略的主要思路是通过判断收盘价是否突破支撑位或阻力位来产生做多或做空信号。默认设置基于8小时K线,但在4小时K线上有更优的参数设置。该策略使用了pivothigh和pivotlow函数来确定支撑位和阻力位,并使用最高价和最低价来判断突破。同时,该策略还设置了止损和止盈。
SR Breakout Strategy是一个基于经典支撑阻力突破思路的交易策略,通过使用pivothigh和pivotlow函数计算支撑位和阻力位,并通过判断收盘价是否突破这些位置来产生交易信号。该策略的优势在于思路清晰,易于实现和优化;同时也存在一些风险,如在震荡行情中表现不佳,以及固定的止损止盈比例可能带来的风险。未来可以考虑从技术指标、止损止盈、过滤条件、支撑阻力优化等方面对该策略进行优化和改进,以提高其稳定性和盈利能力。
