双信号量化反转策略通过结合123反转策略和加速器振荡器指标,实现对趋势反转的判断,获取更准确的交易信号。该策略主要用于股指、外汇、贵金属和能源品种的短线和中线交易。
该策略由两段独立的代码逻辑组成。
第一部分为123反转策略,其判断反转信号的原理是:当收盘价连续两天低于上一收盘价,且9日STOCH指标K线低于D线时产生多头信号;当收盘价连续两天高于上一收盘价,且9日STOCH指号K线高于D线时产生空头信号。
第二部分为加速器振荡器指标。该指标通过计算绝对价格振荡器和其5周期移动平均线的差值,反映绝对价格振荡器的变化速度,可以提前判断趋势反转点。
最后,该策略将两个指标的信号进行组合:当两指标信号同向时(双多或双空),输出该方向的交易信号;当两指标信号不一致时,输出零信号。
该策略结合双重指标判断,可以过滤掉一定的假信号,信号准确可靠。同时利用绝对价格振荡器反映变化加速度的特点,可以提前捕捉到潜在的趋势反转点,从而争取更大的利润空间。
该策略最大的风险在于指标发出信号前价格已经出现明显的反转,导致错过最佳入场点。此外,行情剧烈波动时,指标参数需要进行优化调整。
针对入场点风险,可以结合更多反转指标进行组合,确保信号的可靠性;针对参数优化问题,可以建立动态调整机制,确保参数的合理性。
该策略可以从以下几个方面进行优化:
增加过滤条件,避免在高波动阶段产生错误信号
结合更多反转指标,形成多重验证机制
建立参数自适应机制,动态调整指标参数
优化止损策略,以控制单笔止损
双信号量化反转策略通过双重验证提高信号准确率,有助于把握市场关键的反转点;同时也需要注意防范指标滞后和参数失效的风险,持续对策略进行验证和优化,使之能适应多变的市场环境。该策略适合有一定量化交易经验的投资者使用。

// First strategy
// This System was created from the Book "How I Tripled My Money In The
// Futures Market" by Ulf Jensen, Page 183. This is reverse type of strategies.
// The strategy buys at market, if close price is higher than the previous close
// during 2 days and the meaning of 9-days Stochastic Slow Oscillator is lower than 50.
// The strategy sells at market, if close price is lower than the previous close price
// during 2 days and the meaning of 9-days Stochastic Fast Oscillator is higher than 50.
//
// Secon strategy
// The Accelerator Oscillator has been developed by Bill Williams
// as the development of the Awesome Oscillator. It represents the
// difference between the Awesome Oscillator and the 5-period moving
// average, and as such it shows the speed of change of the Awesome
// Oscillator, which can be useful to find trend reversals before the
// Awesome Oscillator does.
