本策略名称为“123反转与费希尔变换指标组合策略”。该策略集成应用123反转形态判定和费希尔变换指标,在两者发出共同信号时进行买入或卖出。

123反转形态指价格连续三日形成高低缺口,第三日收盘反转前两日趋势的形态。根据统计,123反转的交易获利率较高。

费希尔变换指标对价格作正态化处理,当变换曲线出现突破极值点时,可以有效识别价格反转点。

交易逻辑如下:

  1. 123反转形态显示买入信号或卖出信号。

  2. 费希尔变换曲线显示买入或卖出信号。

  3. 当两者发出同向信号时,进行相应的买入或卖出交易。

  4. 当两者发出反向信号时,保持空仓。

该策略的优势在于指标组合可以提高对价格反转时点的判断准确性。但参数优化仍然关键,需要严格的资金管理。

总体来看,指标集成应用可以形成更全面的分析角度。但交易者仍需保持足够的灵活性,根据市场情况进行策略调整。

// This is combo strategies for get a cumulative signal. 
//
// 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.
//
// Second strategy
// 	Market prices do not have a Gaussian probability density function
// 	as many traders think. Their probability curve is not bell-shaped.
// 	But trader can create a nearly Gaussian PDF for prices by normalizing
// 	them or creating a normalized indicator such as the relative strength
// 	index and applying the Fisher transform. Such a transformed output 
// 	creates the peak swings as relatively rare events.
// 	Fisher transform formula is: y = 0.5 * ln ((1+x)/(1-x))
// 	The sharp turning points of these peak swings clearly and unambiguously
// 	identify price reversals in a timely manner. 
//
// WARNING:
// - For purpose educate only
